Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Basis of Presentation and Description of Business. Tempur Sealy International, Inc., a Delaware corporation, together with its subsidiaries, is a U.S. based, multinational company. The term “Tempur Sealy International” refers to Tempur Sealy International, Inc. only, and the term “Company” refers to Tempur Sealy International, Inc. and its consolidated subsidiaries. The Company develops, manufactures, markets and sells bedding products, which include mattresses, foundations and adjustable bases, and other products, which include pillows and other accessories. The Company also derives income from royalties by licensing Sealy® and Stearns & Foster® brands, technology and trademarks to other manufacturers. The Company sells its products through two sales channels: Wholesale and Direct. (b) Basis of Consolidation. The accompanying financial statements include the accounts of Tempur Sealy International and its controlled subsidiaries and the results of Comfort Revolution, LLC ("Comfort Revolution"). Intercompany balances and transactions have been eliminated. Comfort Revolution is a 45.0% owned joint venture. Comfort Revolution constitutes a variable interest entity (“VIE”) for which the Company is considered to be the primary beneficiary due to the Company's disproportionate share of the economic risk associated with its equity contribution, debt financing and other factors that were considered in the related-party analysis surrounding the identification of the primary beneficiary. The Company is party to put and call arrangements with respect to the common securities that represent the 55.0% non-controlling interest in Comfort Revolution not owned by the Company. The operations of Comfort Revolution are not material to the Company’s Consolidated Financial Statements. The Company also has ownership interests in a group of Asia-Pacific joint ventures to develop markets for Sealy® branded products in those regions. The equity method of accounting is used for these joint ventures, over which the Company has significant influence but does not have effective control, and consolidation is not otherwise required. The Company’s equity in the net income and losses of these investments is reported in equity income in earnings of unconsolidated affiliates in the accompanying Consolidated Statements of Income. The Company’s Asia-Pacific joint ventures are more fully described in Note 6 , "Unconsolidated Affiliate Companies." (c) Use of Estimates. The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Company’s results are affected by economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies and changes in the prices of raw materials, can have a significant effect on operations. (d) Fair Value Measurements. The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the Consolidated Financial Statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows: • Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets. • Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments. • Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements. The classification of fair value measurements within the established three-level hierarchy is based upon the lowest level of input that is significant to the measurements. There were no transfers between levels for the years ended December 31, 2017 or 2016 . The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term maturity of those instruments. The fair value of the Company's financial instruments that are recorded on a recurring basis at fair value is not material. (e) Foreign Currency. Assets and liabilities of non-U.S. subsidiaries, whose functional currency is the local currency, are translated into U.S. dollars at period-end exchange rates. Income and expense items are translated at the average rates of exchange prevailing during the period. The adjustments resulting from translating the financial statements of foreign subsidiaries are included in accumulated other comprehensive loss (“AOCL”), a component of stockholders’ equity/(deficit), and included in net earnings only upon sale or liquidation of the underlying foreign subsidiary or affiliated company. Foreign currency transaction gains and losses are recognized in net earnings based on differences between foreign exchange rates on the transaction date and on the settlement date. These amounts are not considered material to the Consolidated Financial Statements. (f) Derivative Financial Instruments. Derivative financial instruments are used in the normal course of business to manage interest rate and foreign currency exchange risks. The financial instruments used by the Company are straight-forward, non-leveraged instruments. The counterparties to these financial instruments are financial institutions with strong credit ratings. The Company maintains control over the size of positions entered into with any one counterparty and regularly monitors the credit ratings of these institutions. For all transactions designated as hedges, the hedging relationships are formally documented at the inception and on an ongoing basis in offsetting changes in cash flows of the hedged transaction. The Company records derivative financial instruments on the Consolidated Balance Sheets as either an asset or liability measured at its fair value. Changes in a derivative's fair value (i.e. unrealized gains or losses) are recorded each period in earnings or other comprehensive income ("OCI"), depending on whether the derivative is designated and is effective as a hedged transaction, and on the type of hedging relationship. For derivative financial instruments that are designated as a hedge, unrealized gains and losses related to the effective portion are either recognized in income immediately to offset the realized gain or loss on the hedged item, or are deferred and reported as a component of AOCL in stockholders' equity/(deficit) and subsequently recognized in net income when the hedged item affects net income. The change in fair value of the ineffective portion of a derivative financial instrument is recognized in net income immediately. For derivative instruments that are not designated as hedges, the gain or loss related to the change in fair value is also recorded to net income immediately. The effectiveness of the cash flow hedge contracts, including time value, is assessed prospectively and retrospectively on a monthly basis using regression analysis, as well as other timing and probability criteria. For derivative instruments that are not designated as hedges, the gain or loss related to the change in fair value is also recorded in net income immediately. The Company manages a portion of the risk associated with fluctuations in foreign currencies related to intercompany and third party inventory purchases denominated in foreign currencies through foreign exchange forward contracts designated as cash flow hedges. During 2017, the Company had foreign exchange forward contracts designated as cash flow hedges to buy U.S. dollars and to sell Canadian dollars. These foreign exchange forward contracts matured in September 2017. The forward exchange contract asset and liability as of December 31, 2016 and 2015 were based on Level 2 inputs and were not material in either period. The Company is also exposed to foreign currency risk related to intercompany debt and associated interest payments and certain intercompany accounts receivable and accounts payable. To manage the risk associated with fluctuations in foreign currencies related to these assets and liabilities, the Company enters into foreign exchange forward contracts. The Company considers these contracts to be economic hedges. Accordingly, changes in the fair value of these instruments affect earnings during the current period. These foreign exchange forward contracts protect against the reduction in value of forecasted foreign currency cash flows resulting from payments in foreign currencies. (g) Cash and Cash Equivalents. Cash and cash equivalents consist of all highly liquid investments with initial maturities of three months or less. The carrying value of cash and cash equivalents approximates fair value because of the short-term maturity of those instruments. (h) Inventories. Inventories are stated at the lower of cost or market, determined by the first-in, first-out method and consist of the following: December 31, (in millions) 2017 2016 Finished goods $ 121.8 $ 130.1 Work-in-process 11.5 10.7 Raw materials and supplies 49.7 55.7 $ 183.0 $ 196.5 (i) Property, Plant and Equipment. Property, plant and equipment are carried at cost at acquisition date and are depreciated using the straight-line method over their estimated useful lives as follows: Estimated Useful Lives (in years) Buildings 25-30 Computer equipment and software 3-5 Leasehold improvements 4-7 Machinery and equipment 3-7 Office furniture and fixtures 5-7 The Company records depreciation and amortization in cost of sales for long-lived assets used in the manufacturing process, and within each line item of operating expenses for all other long-lived assets. Leasehold improvements are amortized over the shorter of the life of the lease or seven years. Assets under capital lease are included within property, plant and equipment and represent non-cash investing activities. Property, plant and equipment, net consisted of the following: December 31, (in millions) 2017 2016 Machinery and equipment $ 315.0 $ 283.9 Land and buildings 316.2 302.6 Computer equipment and software 114.0 97.2 Furniture and fixtures 57.4 50.4 Construction in progress 63.2 52.9 Total property, plant, and equipment 865.8 787.0 Accumulated depreciation (430.7 ) (364.8 ) Total property, plant and equipment, net $ 435.1 $ 422.2 Depreciation expense, which includes depreciation expense for capital lease assets, for the Company was $65.3 million , $56.1 million and $53.5 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. (j) Long-Lived Assets. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets is assessed by a comparison of the carrying amount of the asset to the estimated future undiscounted net cash flows expected to be generated by the asset or group of assets. If estimated future undiscounted net cash flows are less than the carrying amount of the asset or group of assets, the asset is considered impaired and an expense is recorded in an amount required to reduce the carrying amount of the asset to its then fair value. Fair value generally is determined from estimated discounted future net cash flows (for assets held for use) or net realizable value (for assets held for sale). The Company did not identify any impairments for the years ended December 31, 2017 , 2016 and 2015 . (k) Goodwill and Other Intangible Assets. Intangible assets with finite useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment whenever events or changes in circumstances indicate impairment may have occurred. The Company performs an annual impairment test on goodwill and indefinite-lived intangible assets on October 1 of each year and whenever events or circumstances make it more likely than not that impairment may have occurred. In conducting the impairment test for the North America and International reporting units, the fair value of each of the Company's reporting units is compared to its respective carrying amount including goodwill. If the fair value exceeds the carrying amount, then no impairment exists. If the carrying amount exceeds the fair value, further analysis is performed to assess impairment. The Company’s determination of fair value of the reporting units is based on a discounted cash flow approach, with an appropriate risk-adjusted discount rate, and a market approach. Any identified impairment would result in an adjustment to the Company’s results of operations. The Company also tests its indefinite-lived intangible assets, principally the Tempur and Sealy trade names. The Company tested both trade names for impairment using a “relief-from-royalty” method. Significant assumptions inherent in the methodologies are employed and include such estimates as royalty and discount rates. The Company performed its annual impairment test of goodwill and indefinite-lived intangible assets in 2017 , 2016 and 2015 , and an interim impairment test for its North America reporting unit in March 2017, none of which resulted in the recognition of impairment charges. The most recent annual impairment tests performed as of October 1, 2017, indicated that the fair values of each of the Company's reporting units and indefinite-lived intangible assets were substantially in excess of their carrying values. For further information on goodwill and other intangible assets, refer to Note 5 , “ Goodwill and Other Intangible Assets .” (l) Accrued Sales Returns. The Company allows product returns through certain sales channels and on certain products. Estimated sales returns are provided at the time of sale based on historical sales channel return rates. Estimated future obligations related to these products are provided by a reduction of sales in the period in which the revenue is recognized. The Company considers the impact of recoverable salvage value on sales returns by segment in determining its estimate of future sales returns. The Company had the following activity for accrued sales returns from December 31, 2015 to December 31, 2017 : (in millions) Balance as of December 31, 2015 $ 28.5 Amounts accrued 130.6 Returns charged to accrual (128.8 ) Balance as of December 31, 2016 $ 30.3 Amounts accrued 102.1 Returns charged to accrual (102.4 ) Balance as of December 31, 2017 $ 30.0 As of December 31, 2017 and 2016 , $19.6 million and $20.0 million of accrued sales returns is included as a component of accrued expenses and other current liabilities and $10.4 million and $10.3 million of accrued sales returns is included in other non-current liabilities on the Company’s accompanying Consolidated Balance Sheets, respectively. (m) Warranties. The Company provides warranties on certain products, which vary based by segment, product and brand. Estimates of warranty expenses are based primarily on historical claims experience and product testing. Estimated future obligations related to these products are charged to cost of sales in the period in which the related revenue is recognized. In estimating its warranty obligations, the Company considers the impact of recoverable salvage value on warranty costs by segment in determining its estimate of future warranty obligations. The Company provides warranties on mattresses with varying warranty terms. Tempur mattresses sold in the North America segment and all Sealy mattresses have warranty terms ranging from 10 to 25 years, generally non-prorated for the first 10 to 15 years and then prorated for the balance of the warranty term. Tempur mattresses sold in the International segment have warranty terms ranging from 5 to 15 years, non-prorated for the first 5 years and then prorated on a straight-line basis for the last 10 years of the warranty term. Tempur pillows have a warranty term of 3 years, non-prorated. The Company had the following activity for warranties from December 31, 2015 to December 31, 2017 : (in millions) Balance as of December 31, 2015 $ 29.6 Amounts accrued 50.0 Warranties charged to accrual (49.7 ) Balance as of December 31, 2016 $ 29.9 Amounts accrued 50.3 Warranties charged to accrual (43.5 ) Balance as of December 31, 2017 $ 36.7 As of December 31, 2017 and 2016 , $16.7 million and $14.3 million of accrued warranty expense is included as a component of accrued expenses and other current liabilities and $20.0 million and $15.6 million of accrued warranty expense is included in other non-current liabilities on the Company’s accompanying Consolidated Balance Sheets, respectively. (n) Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are also recognized for the estimated future effects of tax loss carry forwards. The effect of changes in tax rates on deferred taxes is recognized in the period in which the enactment dates change. The deferred tax assets and liabilities have been re-valued pursuant to the U.S. Tax Reform Act as discussed in Note 13 - Income Taxes . Valuation allowances are established when necessary on a jurisdictional basis to reduce deferred tax assets to the amounts expected to be realized. The Company accounts for uncertain foreign and domestic tax positions utilizing a proscribed recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. (o) Revenue Recognition. Sales of products are recognized when persuasive evidence of an arrangement exists, title passes to customers and the risks and rewards of ownership are transferred, the sales price is fixed or determinable, and collectability is reasonably assured. The Company extends volume discounts to certain customers, as well as promotional allowances, floor sample discounts, commissions paid to retail associates and slotting fees, and reflects these amounts as a reduction of sales at the time revenue is recognized based on historical experience. The Company also reports sales net of tax assessed by qualifying governmental authorities. The Company extends credit based on the creditworthiness of its customers. No collateral is required on sales made in the normal course of business. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company regularly reviews the adequacy of its allowance for doubtful accounts. The Company determines the allowance for doubtful accounts based on historical write-off experience and current economic conditions and also considers factors such as customer credit, past transaction history with the customer and changes in customer payment terms when determining whether the collection of a customer receivable is reasonably assured. Account balances are charged off against the allowance after all reasonable means of collection have been exhausted and the potential for recovery is considered remote. The allowance for doubtful accounts included in accounts receivable, net in the accompanying Consolidated Balance Sheets was $27.4 million and $22.4 million as of December 31, 2017 and 2016 , respectively. The Company reflects all amounts billed to customers for shipping and handling in net sales and the costs incurred from shipping and handling product in cost of sales. Amounts included in net sales for shipping and handling were $11.3 million , $11.7 million and $11.1 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Amounts included in cost of sales for shipping and handling were $159.3 million , $155.1 million and $161.6 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. (p) Cost of Sales . Costs associated with net sales are recorded in cost of sales. Cost of sales includes the costs of receiving, producing, inspecting, warehousing, insuring, and shipping goods during the period, as well as depreciation and amortization of long-lived assets used in these processes. Cost of sales also includes shipping and handling costs associated with the delivery of goods to customers and costs associated with internal transfers between plant locations. (q) Cooperative Advertising, Rebate and Other Promotional Programs. The Company enters into programs with customers to provide funds for advertising and promotions. The Company also enters into volume and other rebate programs with customers. When sales are made to these customers, the Company records liabilities pursuant to these programs. The Company periodically assesses these liabilities based on actual sales and claims to determine whether all of the cooperative advertising earned will be used by the customer or whether the customer will meet the requirements to receive rebate funds. The Company generally negotiates these programs on a customer-by-customer basis. Some of these agreements extend over several years. Significant estimates are required at any point in time with regard to the ultimate reimbursement to be claimed by the customers. Subsequent revisions to the estimates are recorded and charged to earnings in the period in which they are identified. Rebates and cooperative advertising are classified as a reduction of revenue and presented within net sales in the accompanying Consolidated Statements of Income. Certain cooperative advertising expenses are reported as components of selling and marketing expenses in the accompanying Consolidated Statements of Income because the Company receives an identifiable benefit and the fair value of the advertising benefit can be reasonably estimated. (r) Advertising Costs. The Company expenses advertising costs as incurred except for production costs and advance payments, which are deferred and expensed when advertisements run for the first time. Direct response advance payments are deferred and amortized over the life of the program. Advertising costs are included in selling and marketing expenses in the accompanying Consolidated Statements of Income. Advertising costs charged to expense were $284.1 million , $352.7 million and $360.5 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Advertising costs include expenditures for shared advertising costs that the Company reimburses to customers under its integrated and cooperative advertising programs. Cooperative advertising costs paid to customers are recorded as a component of selling and marketing expenses within the Consolidated Statements of Income to the extent of the estimated fair value of the customer's underlying advertisement when the customer provides proof of advertising. The Company periodically assesses the liabilities recorded for cooperative advertising based on actual sales and claims to determine whether all of the cooperative advertising earned will be used by the customer. Advertising costs deferred and included in prepaid expenses and other current assets in the accompanying Consolidated Balance Sheets were $3.8 million and $7.4 million as of December 31, 2017 and 2016 , respectively. (s) Research and Development Expenses. Research and development expenses for new products are expensed as they are incurred and are included in general, administrative and other expenses in the accompanying Consolidated Statements of Income. Research and development costs charged to expense were $21.7 million , $26.7 million and $28.7 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. (t) Royalty Income and Expense. The Company recognizes royalty income based on sales of Sealy® and Stearns & Foster® branded products by various licensees. The Company also pays royalties to other entities for the use of their names on products produced by the Company. Royalty income, net of royalty expense, was $20.8 million , $19.5 million and $18.3 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. (u) Stock-based Compensation. The Company accounts for stock-based payment transactions in which the Company receives employee services in exchange for equity instruments of the Company. Stock-based compensation cost for restricted stock units (“RSUs”), performance restricted stock units (“PRSUs”) and deferred stock units (“DSUs”) is measured based on the closing fair market value of the Company’s common stock on the date of grant. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair value as calculated by the Black-Scholes option-pricing model. The Company recognizes stock-based compensation cost as expense for awards other than its PRSUs ratably on a straight-line basis over the requisite service period. The Company recognizes stock-based compensation cost associated with its PRSUs over the requisite service period if it is probable that the performance conditions will be satisfied. Further information regarding stock-based compensation can be found in Note 11 , “ Stock-based Compensation .” (v) Treasury Stock. Subject to Delaware law, and the limitations in the Company's 2016 Credit Agreement (as defined in Note 7 , "Debt") and the Company's other debt agreements, the Board of Directors may authorize share repurchases of the Company’s common stock (“Stock Repurchase Authorizations”). Purchases made pursuant to Stock Repurchase Authorizations may be carried out through open market transactions, negotiated purchases or otherwise, at times and in such amounts as the Company deems appropriate. Stock repurchased under Stock Repurchase Authorizations is held in treasury for general corporate purposes, including issuances under various employee stock-based award plans. On February 1, 2016, the Board of Directors authorized a stock repurchase program pursuant to which the Company was authorized to repurchase shares of Tempur Sealy International's common stock. For the year ended December 31, 2017 , the Company repurchased 0.6 million shares for approximately $40.1 million under the share repurchase authorization. As of December 31, 2017 , the Company had approximately $226.9 million remaining under the existing share repurchase authorization. In addition, the Company acquired 0.1 million and 0.0 million shares upon the vesting of certain PRSUs, which were withheld to satisfy tax withholding obligations during the year ended December 31, 2017 and 2016 , respectively. The shares withheld were valued at the closing price of the common stock on the New York Stock Exchange on the vesting date or last business day prior to the vesting date, resulting in approximately $4.8 million and $2.0 million in treasury stock acquired during the year ended December 31, 2017 and 2016 , respectively. Treasury stock is accounted for under the cost method and reported as a reduction of stockholders’ equity/(deficit). Stock Repurchase Authorizations may be suspended, limited or terminated at any time without notice. (w) Self-Insurance. The Company is self-insured up to $0.8 million per claim per year for certain losses related to medical claims with excess loss coverage. The Company also utilizes large deductible policies to insure claims related to general liability, product liability, automobile, and workers’ compensation. The Company’s recorded liability for workers’ compensation represents an estimate of the ultimate cost of claims incurred as of the Consolidated Balance Sheet date. The estimated workers' compensation liability is undiscounted and is established based upon analysis of historical and actuarial estimates, and is reviewed by the Company and third party actuaries on a quarterly basis to ensure that the liability is appropriate. As of December 31, 2017 and 2016 , $4.8 million and $8.6 million , respectively, of the recorded undiscounted liability is included in accrued expenses and other current liabilities and $15.9 million and $12.3 million , respectively, is included in other non-current liabilities within the accompanying Consolidated Balance Sheets. During 2016, the Company entered into a retroactive insurance policy to limit exposure on historical worker's compensation claims. As of December 31, 2017 and 2016, $2.4 million and $0.0 million , respectively, are included in prepaid expenses and other current assets and $ 7.6 million and $14.2 million , respectively, are included in other non-current assets within the accompanying Consolidated Balance Sheets, which together represent the value of expected recoveries related to the underlying insured events. The related liabilities for the Company's worker's compensation exposure are included in other non-current liabilities within the accompanying Consolidated Balance Sheets. (x) Pension Obligations. The Company has a noncontributory, defined benefit pension plan covering current and former hourly employees at two of its active Sealy plants and ten previously closed Sealy U.S. facilities. Sealy Canada, Ltd. (a 100.0% owned subsidiary of the Company) also sponsors a noncontributory, defined benefit pension plan covering hourly employees at one of its facilities. Both plans provide retirement and survivorship benefits based on the employees' credited years of service. The Company's funding policy provides for contributions of an amount between the minimum required and maximum amount that can be deducted for federal income tax purposes. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at December 31, the measurement date. The benefit obligation is the projected benefit obligation (“PBO”). The PBO represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. The measurement of the PBO is based on the Company’s estimates and actuarial valuations. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions that require significant judgment, including estimates of discount rates, expected return on plan assets, rate of compensation increases, interest crediting rates and mortality rates. (y) Restructuring Activities. For the year ended December 31, 2016 , the Company initiated certain restructuring activities, which included headcount reductions and store closures. As a result, the Company recognized $8.3 million of restructuring expenses consisting primarily of severance benefits and costs associated with store closures, which are recorded in cost of sales, selling and marketing expenses, and general, administrative and other expenses. (z) Customer Contract Termination. During the week of January 23, 2017, the Company was unexpectedly notified by the senior management of Mattress Firm, Inc. ("Mattress Firm") and representatives of Steinhoff International Holdi

Accounting Changes and Error Corrections [Abstract]
Revisions of Previously-Issued Financial Statements	Revisions of Previously-Issued Financial Statements During the fourth quarter of 2017, the Company identified accounting and operational irregularities associated with a Latin American subsidiary. These errors were immaterial to each of the prior reporting periods affected. However, the Company concluded that the cumulative effect of correcting the errors in 2017 would materially misstate the Company’s Consolidated Statement of Income for the year ended December 31, 2017. Accordingly, the prior period results have been revised. The cumulative impact for both Income before income taxes and Net income attributable to Tempur Sealy International, Inc. for the periods prior to January 1, 2015 is $27.2 million and is reflected in beginning retained earnings for January 1, 2015. The table below illustrates the effect of the corrections on the Company's consolidated financial statements for the periods presented. Year Ended December 31, 2016 Year Ended December 31, 2015 Previously Reported Correction As Revised Previously Reported Correction As Revised Net sales $ 3,127.3 $ 1.6 $ 3,128.9 $ 3,151.2 $ 3.4 $ 3,154.6 Gross profit 1,309.4 (1.9 ) 1,307.5 1,248.9 0.3 1,249.2 Operating income 415.5 (5.1 ) 410.4 309.1 (2.6 ) 306.5 Income before income taxes 283.3 (11.5 ) 271.8 200.1 (9.0 ) 191.1 Income tax provision (86.8 ) — (86.8 ) (125.4 ) — (125.4 ) Net income before non-controlling interests 196.5 (11.5 ) 185.0 74.7 (9.0 ) 65.7 Net income attributable to Tempur Sealy International, Inc. $ 202.1 $ (11.5 ) $ 190.6 $ 73.5 $ (9.0 ) $ 64.5 December 31, 2016 Previously Reported Correction As Revised Total assets $ 2,702.6 $ (3.8 ) $ 2,698.8 Total liabilities 2,707.2 25.9 2,733.1 Retained earnings 1,312.4 (47.6 ) 1,264.8 Total stockholders' deficit (12.2 ) (29.7 ) (41.9 ) Total liabilities, redeemable non-controlling interest and stockholders' deficit $ 2,702.6 $ (3.8 ) $ 2,698.8

Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2014-09, Revenue From Contracts With Customers (Topic 606), that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This ASU is based on the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The Company conducted a risk assessment and had developed a transition plan that enabled the Company to meet the implementation requirement. Revenue streams and performance obligations include product sales, sales-based royalties and warranties. The Company's contracts also include forms of variable consideration, including rebates (volume, cash and cooperative advertising), trade or other support, free products, slotting fees, and sales returns. Based on the evaluation of the Company's current contracts and the related revenue streams and performance obligations, most will be recorded consistently under both the current and new standard. The majority of the Company's revenue transactions are not accounted for under industry-specific guidance that will be superseded by Topic 606 and generally consist of a single performance obligation to transfer promised goods. The Company adopted the new revenue guidance effective January 1, 2018 using the modified retrospective method of adoption. The largest impacts as a result of the new standard are the new required qualitative and quantitative disclosures. Other presentation and disclosure changes include the reclassification of royalty income to revenue and changes in the balance sheet classification for sales returns. Under the new standard, the Company will continue to recognize the amount of consideration received or receivable that is expected to be returned as a refund liability, representing the Company's obligation to return the customer’s consideration. The Company evaluated the impact of the adoption on the classification of cooperative advertising programs and other promotional programs with the Company's customers. The impact of adoption to these promotional programs did not result in material changes in the Company's recognition or presentation of costs within the Company's Consolidated Statements of Income. As required under the new standard, the Company will establish a return asset for the right to recover the goods returned by the customer in 2018. The Company recognized a cumulative effect of initially applying the new standard as a decrease to the opening balance of retained earnings for approximately $3.0 million , net of tax. The Company does not expect the impact to cost of sales as a result of adjusting the return asset on an ongoing basis to be material. The return asset will be subject to impairment assessments on an ongoing basis. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases , that requires lessees to recognize most leases on the balance sheet and provides for expanded disclosures on key information about leasing arrangements. This ASU is effective for interim and annual periods beginning after December 5, 2018, which means it will become effective for the Company on January 1, 2019. In transition, the Company is required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating this ASU to determine the impact it will have on the Company's Consolidated Financial Statements. The Company expects that the adoption of the standard will result in a material increase to the assets and liabilities within the Consolidated Balance Sheets. Employee Share-Based Payments In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and the classification on the statement of cash flows. The Company adopted this ASU as of January 1, 2017. As a result of the adoption of this ASU: • The Company recognized all excess tax benefits and tax deficiencies as income tax provision or benefit in the Consolidated Statement of Income. The Company recognized excess tax deficiencies of $0.7 million for the year ended December 31, 2017. • The Company is prospectively presenting these excess tax benefits and tax deficiencies as an operating activity on the Consolidated Statement of Cash Flows. • The Company adopted a change in accounting policy to recognize forfeitures of awards as they occur instead of estimating potential forfeitures. Historically, the Company estimated the number of awards expected to be forfeited and adjusted the estimate when it was no longer probable that employees would fulfill their service conditions. The effect of this change in accounting policy is not material. Pensions In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which is accounting guidance that will change how employers who sponsor defined benefit pension and/or postretirement benefit plans present the net periodic benefit cost in the Consolidated Statements of Income. This guidance requires employers to present the service cost component of net periodic benefit cost in the same caption within the Consolidated Statements of Income as other employee compensation costs from services rendered during the period. All other components of the net periodic benefit cost will be presented separately outside of the operating income caption. This guidance must be applied retrospectively and will become effective for the Company on January 1, 2018. Adoption of this guidance will result in a reclassification of pension and other postretirement plan non-service income and re-measurement adjustments, net from within operating income to non-operating income.

(4) Capital lease obligations are a non-cash financing activity. 2016 Credit Agreement On April 6, 2016, the Company entered into a senior secured credit agreement ("2016 Credit Agreement") with a syndicate of banks. The 2016 Credit Agreement replaced the Company’s 2012 Senior Secured Credit Agreement ("2012 Credit Agreement"). The 2016 Credit Agreement provides for a $500.0 million revolving credit facility, a $500.0 million initial term loan facility and a $100.0 million delayed draw term loan facility. At any time, the Company may also elect to request the establishment of one or more incremental term loan facilities and/or increase commitments under the revolving credit facility in an aggregate amount of up to $500.0 million . A portion of the revolving credit facility of up to $250.0 million is available in Canadian Dollars, Pounds Sterling, the Euro and any additional currencies determined by mutual agreement of the Company, the administrative agent and the lenders under the revolving credit facility. A portion of the revolving credit facility of up to $100.0 million is available for the issuance of letters of credit for the account of the Company and a portion of the revolving credit facility of up to $50.0 million is available for swing line loans to the Company. Borrowings under the 2016 Credit Agreement will generally bear interest, at the election of Tempur Sealy International and the other subsidiary borrowers, at either (i) LIBOR plus the applicable margin or (ii) Base Rate plus the applicable margin. The applicable margins are determined by a pricing grid based on the consolidated total net leverage ratio of the Company following the delivery of the Consolidated Financial Statements of the Company for the most recent quarter. The delayed draw term loan facility has identical pricing to the revolving credit facility and initial term loan facility. For the period ended December 31, 2017 , the margin was either (i) LIBOR plus 1.75% per annum, or (ii) Base Rate plus 0.75% . Obligations under the 2016 Credit Agreement are guaranteed by the Company’s existing and future direct and indirect wholly-owned domestic subsidiaries, subject to certain exceptions. The 2016 Credit Agreement is secured by a security interest in substantially all of Tempur Sealy International’s and the other subsidiary borrowers’ domestic assets and the domestic assets of each subsidiary guarantor, whether owned as of the closing or thereafter acquired, including a pledge of 100.0% of the equity interests of each subsidiary guarantor that is a domestic entity (subject to certain limited exceptions) and 65.0% of the voting equity interests of any direct first tier foreign entity owned by a subsidiary guarantor. The 2016 Credit Agreement requires compliance with certain financial covenants providing for maintenance of a minimum consolidated interest coverage ratio, maintenance of a maximum consolidated total net leverage ratio, and maintenance of a maximum consolidated secured net leverage ratio. The consolidated total net leverage ratio is calculated using consolidated funded debt less qualified cash. Consolidated funded debt includes debt recorded on the Consolidated Balance Sheets as of the reporting date, plus letters of credit outstanding and other short-term debt. The Company is allowed to subtract from consolidated funded debt an amount equal to 100.0% of domestic qualified cash and 60.0% of foreign qualified cash, the aggregate of which cannot exceed $150.0 million at the end of the reporting period. As of December 31, 2017 , domestic qualified cash was $18.4 million and foreign qualified cash was $14.1 million . As of December 31, 2017 , the Company's consolidated total net leverage ratio was 3.91 times, within the covenant in the Company's debt agreements which limits this ratio to 5.00 times for the year ended December 31, 2017 . The 2016 Credit Agreement contains certain customary negative covenants, which include limitations on liens, investments, indebtedness, dispositions, mergers and acquisitions, the making of restricted payments, changes in the nature of business, changes in fiscal year, transactions with affiliates, use of proceeds, prepayments of certain indebtedness, entry into burdensome agreements and changes to governing documents and other junior financing documents. The 2016 Credit Agreement also contains certain customary affirmative covenants and events of default, including upon a change of control. The Company was in compliance with all applicable covenants in the 2016 Credit Agreement at December 31, 2017 . The Company is required to pay a commitment fee on the unused portion of the revolving credit facility. The commitment fee rate is determined by a pricing grid based on the consolidated total net leverage ratio of the Company. The commitment fee is payable quarterly in arrears following the delivery of Consolidated Financial Statements for the most recent quarter and on the date of termination or expiration of the commitments under the revolving credit facility. The Company and the other borrowers also pay customary letter of credit issuance and other fees under the 2016 Credit Agreement. For the period ended December 31, 2017 , the Company's commitment fee rate was 0.30% . In 2016, the Company also borrowed $100.0 million using the delayed draw term loan facility under the Company's 2016 Credit Agreement in connection with the repayment of the 8.0% Sealy Notes. The commitment to provide the delayed draw term loan facility terminated with its funding. As a result of the Company’s 2016 Credit Agreement, $3.6 million of deferred financing costs were capitalized in 2016 and will be amortized as interest expense over the respective debt instrument period, 5 years , using the effective interest method. In addition, the Company expensed $1.9 million of lender fees associated with this transaction in 2016, which is included in loss on extinguishment of debt in the Consolidated Statements of Income. The Company used the proceeds from the 2016 Credit Agreement to repay in full and terminate the 2012 Credit Agreement. The 2012 Credit Agreement initially provided for (i) a revolving credit facility of $350.0 million , (ii) a Term A facility of $550.0 million and (iii) a Term B facility of $870.0 million. In conjunction with the repayment of all outstanding borrowings on the 2012 Credit Agreement, the Company expensed approximately $11.0 million of deferred financing costs in 2016, which is included in loss on extinguishment of debt in the Consolidated Statements of Income. Senior Notes 2026 Senior Notes On May 24, 2016, Tempur Sealy International issued $600.0 million aggregate principal amount of 5.500% 2026 Senior Notes in a private offering to qualified institutional buyers pursuant to Rule 144A of the Securities Act of 1933, as amended (the "Securities Act"), and to certain non-U.S. persons in accordance with Regulation S under the Securities Act. The 2026 Senior Notes were issued pursuant to an indenture, dated as of May 24, 2016 (the "2026 Indenture"), among Tempur Sealy International, certain subsidiaries of Tempur Sealy International as guarantors (the "Combined Guarantor Subsidiaries"), and The Bank of New York Mellon Trust Company, N.A., as trustee. The 2026 Senior Notes are general unsecured senior obligations of Tempur Sealy International and are guaranteed on a senior unsecured basis by the Combined Guarantor Subsidiaries. The 2026 Senior Notes mature on June 15, 2026, and interest is payable semi-annually in arrears on each June 15 and December 15, which began on December 15, 2016. The gross proceeds from the 2026 Senior Notes were used to refinance the $375.0 million aggregate principal amount of 6.875% 2020 Senior Notes and to pay related fees and expenses, and the remaining funds were used for share repurchases and general corporate purposes. Tempur Sealy International has the option to redeem all or a portion of the 2026 Senior Notes at any time on or after June 15, 2021. The initial redemption price is 102.750% of the principal amount, plus accrued and unpaid interest, if any. The redemption price will decline each year after 2021 until it becomes 100.0% of the principal amount beginning on June 15, 2024. In addition, Tempur Sealy International has the option at any time prior to June 15, 2021 to redeem some or all of the 2026 Senior Notes at 100.0% of the original principal amount plus a “make-whole” premium and accrued and unpaid interest, if any. Tempur Sealy International may also redeem up to 35.0% of the 2026 Senior Notes prior to June 15, 2019, under certain circumstances with the net cash proceeds from certain equity offerings, at 105.500% of the principal amount plus accrued and unpaid interest, if any. Tempur Sealy International may make such redemptions as described in the preceding sentence only if, after any such redemption, at least 65.0% of the original aggregate principal amount of the 2026 Senior Notes issued remains outstanding. The 2026 Indenture restricts the ability of Tempur Sealy International and the ability of certain of its subsidiaries to, among other things: (i) incur, directly or indirectly, debt; (ii) make, directly or indirectly, certain investments and restricted payments; (iii) incur or suffer to exist, directly or indirectly, liens on its properties or assets; (iv) sell or otherwise dispose of assets, directly or indirectly; (v) create or otherwise cause or suffer to exist any consensual restriction on the right of certain of the subsidiaries of Tempur Sealy International to pay dividends or make any other distributions on or in respect of their capital stock; (vi) enter into transactions with affiliates; (vii) engage in sale-leaseback transactions; (viii) purchase or redeem capital stock or subordinated indebtedness; (ix) issue or sell stock of restricted subsidiaries; and (x) effect a consolidation or merger. These covenants are subject to a number of exceptions and qualifications. In conjunction with the issuance and sale of the 2026 Senior Notes, Tempur Sealy International and the Combined Guarantor Subsidiaries agreed through a Registration Rights Agreement to exchange the 2026 Senior Notes for a new issue of substantially identical senior notes registered under the Securities Act (the "Exchange Offer"). On October 18, 2016, Tempur Sealy International completed the Exchange Offer, with 100% of the outstanding notes tendered and received for new 2026 Senior Notes registered under the Securities Act. As a result of the issuance of the 2026 Senior Notes, $3.1 million of deferred financing costs were capitalized in 2016 and will be amortized as interest expense over the respective debt instrument period, 10 years , using the effective interest method. In addition, the Company expensed $5.9 million of lender fees associated with this transaction in 2016, which is included in loss on extinguishment of debt in the Consolidated Statements of Income. The Company used the proceeds from the 2026 Senior Notes to refinance the 2020 Senior Notes and to pay related fees and expenses. The 2020 Senior Notes were redeemed at a price equal to the principal amount thereof and the applicable "make-whole" premium, $23.6 million , which is included in loss on extinguishment of debt in the Consolidated Statements of Income. In conjunction with the refinancing of the 2020 Senior Notes, the Company wrote off approximately $4.8 million of deferred financing costs in the second quarter of 2016, which is included in loss on extinguishment of debt in the Consolidated Statements of Income. 2023 Senior Notes On September 24, 2015, Tempur Sealy International issued $450.0 million aggregate principal amount of 5.625% 2023 Senior Notes in a private offering to qualified institutional buyers pursuant to Rule 144A of the Securities Act, and to certain non-U.S. persons in accordance with Regulation S under the Securities Act. The 2023 Senior Notes were issued pursuant to an indenture, dated as of September 24, 2015 (the “2023 Indenture”), among Tempur Sealy International, the Combined Guarantor Subsidiaries (the Combined Guarantor Subsidiaries are the same under the 2026 Indenture, the 2023 Indenture and the 2020 Indenture), and The Bank of New York Mellon Trust Company, N.A., as trustee. The 2023 Senior Notes are general unsecured senior obligations of Tempur Sealy International and are guaranteed on a senior unsecured basis by the Combined Guarantor Subsidiaries. The 2023 Senior Notes mature on October 15, 2023, and interest is payable semi-annually in arrears on each April 15 and October 15, which began on April 15, 2016. The gross proceeds from the 2023 Senior Notes were used to refinance a portion of the term loan debt under the 2012 Credit Agreement and to pay related fees and expenses. Tempur Sealy International has the option to redeem all or a portion of the 2023 Senior Notes at any time on or after October 15, 2018. The initial redemption price is 104.219% of the principal amount, plus accrued and unpaid interest, if any. The redemption price will decline each year after 2018 until it becomes 100.0% of the principal amount beginning on October 15, 2021. In addition, Tempur Sealy International has the option at any time prior to October 15, 2018 to redeem some or all of the 2023 Senior Notes at 100.0% of the original principal amount plus a “make-whole” premium and accrued and unpaid interest, if any. Tempur Sealy International may also redeem up to 35.0% of the 2023 Senior Notes prior to October 15, 2018, under certain circumstances with the net cash proceeds from certain equity offerings, at 105.625% of the principal amount plus accrued and unpaid interest, if any. Tempur Sealy International may make such redemptions as described in the preceding sentence only if, after any such redemption, at least 65.0% of the original aggregate principal amount of the 2023 Senior Notes issued remains outstanding. The 2023 Indenture restricts the ability of Tempur Sealy International and the ability of certain of its subsidiaries to, among other things: (i) incur, directly or indirectly, debt; (ii) make, directly or indirectly, certain investments and restricted payments; (iii) incur or suffer to exist, directly or indirectly, liens on its properties or assets; (iv) sell or otherwise dispose of, directly or indirectly, assets; (v) create or otherwise cause or suffer to exist any consensual restriction on the right of certain of the subsidiaries of Tempur Sealy International to pay dividends or make any other distributions on or in respect of their capital stock; (vi) enter into transactions with affiliates; (vii) engage in sale-leaseback transactions; (viii) purchase or redeem capital stock or subordinated indebtedness; (ix) issue or sell stock of restricted subsidiaries; and (x) effect a consolidation or merger. These covenants are subject to a number of exceptions and qualifications. In conjunction with the issuance and sale of the 2023 Senior Notes, Tempur Sealy International and the Combined Guarantor Subsidiaries agreed through a Registration Rights Agreement to exchange the 2023 Senior Notes for a new issue of substantially identical senior notes registered under the Securities Act (the "2023 Exchange Offer"). On April 4, 2016, Tempur Sealy International completed the 2023 Exchange Offer, with 100% of the outstanding notes tendered and received for new 2023 Senior Notes registered under the Securities Act. Securitized Debt On April 12, 2017, Tempur Sealy International and certain of its subsidiaries entered into a securitization transaction with respect to certain accounts receivable due to and certain of the Company's subsidiaries (the "Accounts Receivable Securitization"). In connection with this transaction, Tempur Sealy International and its wholly-owned special purpose subsidiary, Tempur Sealy Receivables, LLC, entered into a credit agreement that provides for revolving loans to be made from time to time in a maximum amount that varies over the course of the year based on the seasonality of the Company's accounts receivable and is subject to an overall limit of $120.0 million . The obligations of the Company under the Accounts Receivable Securitization are secured by the accounts receivable and certain related rights and the facility agreements contain customary events of default. The accounts receivable continue to be owned by the Company and its subsidiaries and continue to be reflected as assets on the Company’s Consolidated Balance Sheets and represent collateral up to the amount of the borrowings under this facility. Borrowings under this facility are classified as long-term debt within the Consolidated Balance Sheets. Fair Value Financial instruments, although not recorded at fair value on a recurring basis, include cash and cash equivalents, accounts receivable, accounts payable, and the Company's debt obligations. The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximate fair value using Level 1 inputs because of the short-term maturity of those instruments. Borrowings under the 2016 Credit Agreement and the securitized debt are at variable interest rates and accordingly their carrying amounts approximate fair value. The fair value of the following material financial instruments were based on Level 2 inputs estimated using discounted cash flows and market-based expectations for interest rates, credit risk, and the contractual terms of debt instruments. The fair values of these material financial instruments are as follows: Fair Value (in millions) December 31, 2017 December 31, 2016 2023 Senior Notes $ 470.9 $ 468.5 2026 Senior Notes 618.1 606.8 Capital Leases The Company is party to capital leases as of December 31, 2017 and 2016 . The approximate remaining life of the leases ranges from 1 to 14 years as of December 31, 2017 , with several including an option to extend the lease term. Deferred Financing Costs The Company capitalizes costs associated with the issuance of debt and amortizes these costs as additional interest expense over the lives of the debt instruments using the effective interest method. These costs are recorded as deferred financing costs as a direct reduction from the carrying amount of the corresponding debt liability in the accompanying Consolidated Balance Sheets and the related amortization is included in interest expense, net in the accompanying Consolidated Statements of Income. Upon the prepayment of the related debt, the Company accelerates the recognition of an appropriate amount of the costs. Future Obligations As of December 31, 2017 , the scheduled maturities of long-term debt outstanding, including capital lease obligations, for each of the next five years and thereafter are as follows: (in millions) 2018 $ 72.4 2019 92.9 2020 59.3 2021 442.1 2022 5.7 Thereafter 1,090.1 Total $ 1,762.5

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans 401(k) Plan The Company has a defined contribution plan ("the 401(k) Plan") whereby eligible employees may contribute up to 85.0% of their pay subject to certain limitations as defined by the 401(k) Plan. Employees are eligible to participate in the 401(k) Plan upon hire and are eligible to receive matching contributions upon six months of continuous employment with the Company. The 401(k) Plan provides a 100.0% match of the first 3.0% and 50.0% of the next 2.0% of eligible employee contributions. The match for union employees is based on the applicable collective bargaining arrangement. All matching contributions vest immediately. The Company incurred $4.0 million , $6.7 million and $7.3 million of expenses associated with the 401(k) Plan for the years ended December 31, 2017 , 2016 and 2015 , respectively, which are included in the Consolidated Statements of Income. Company Defined Benefit Pension Plans The Company has a noncontributory, defined benefit pension plan covering current and former hourly employees at only two of its active Sealy plants and ten previously closed Sealy U.S. facilities. Sealy Canada, Ltd. (a 100.0% owned subsidiary of the Company) also sponsors a noncontributory, defined benefit pension plan covering hourly employees at one of its facilities (collectively, referred to as the "Plans"). The Plans provide retirement and survivorship benefits based on the employees’ credited years of service. The Company’s funding policy provides for contributions of an amount between the minimum required and maximum amount that can be deducted for federal income tax purposes. The Plans' assets consist of investments in various common/collective trusts with equity investment strategies diversified across multiple industry sectors and company market capitalization within specific geographical investment strategies, fixed income common/collective trusts, which invest primarily in investment-grade and high-yield corporate bonds and U.S. treasury securities, as well as money market mutual funds. The fixed income investments are diversified as to ratings, maturities, industries and other factors. The Plans' assets contain no significant concentrations of risk related to individual securities or industry sectors. The Plans have no direct investment in the Company's common stock. The long-term rate of return for the Plans is based on the weighted average of the Plans’ investment allocation and the historical returns for those asset categories. Because future compensation levels are not a factor in these Plans’ benefit formulas, the accumulated benefit obligation is equal to the projected benefit obligation as reported below. The discount rate is based on the returns on long-term bonds in the private sector and incorporates a long-term inflation rate. Summarized information for the Plans follows: Expenses and Status Components of net periodic pension cost which is included in general, administrative and other expenses included in the accompanying Consolidated Statements of Income for the years ended December 31 were as follows: (in millions) 2017 2016 2015 Service cost $ 0.9 $ 0.8 $ 0.8 Interest cost 1.2 1.2 1.9 Expected return on assets (1.5 ) (1.3 ) (2.2 ) Amortization of prior service cost 0.1 — — Settlement loss — 0.2 1.3 Net periodic pension cost $ 0.7 $ 0.9 $ 1.8 The other changes in plan assets and benefit obligations recognized in other comprehensive loss (income) for the years ended December 31 were: (in millions) 2017 2016 2015 Net loss $ 0.4 $ 1.5 $ 0.2 Amortization of prior service cost (0.1 ) — — Amortization or settlement recognition of net loss — (0.2 ) (1.3 ) New prior service cost 0.5 — 0.1 Total recognized in other comprehensive loss (income) $ 0.8 $ 1.3 $ (1.0 ) The following assumptions, calculated on a weighted-average basis, were used to determine net periodic pension cost for the Company’s Plans for the years ended December 31: 2017 2016 2015 Discount rate (a) 4.07 % 4.27 % 4.12 % Expected long-term return on plan assets 6.64 % 6.71 % 7.05 % (a) The discount rates used in 2017 to determine the expenses for the U.S. retirement plan and Canadian retirement plan were 4.06% and 4.10% , respectively. The discount rates used in 2016 to determine the expenses for the U.S. retirement plan and Canadian retirement plan were 4.26% and 4.30% , respectively. Obligations and Funded Status The measurement date for the Company's Plans is December 31. The funded status of the Plans as of December 31 was as follows: (in millions) 2017 2016 Change in Benefit Obligation: Projected benefit obligation at beginning of year $ 28.0 $ 28.2 Service cost 0.9 0.8 Interest cost 1.2 1.2 Plan amendments 0.5 — Actuarial loss 2.3 0.8 Settlements — (2.0 ) Benefits paid (0.9 ) (1.1 ) Expenses paid (0.1 ) — Foreign currency exchange rate changes 0.2 0.1 Projected benefit obligation at end of year $ 32.1 $ 28.0 Change in Plan Assets: Fair value of plan assets at beginning of year $ 21.7 $ 13.9 Actual return on plan assets 3.5 0.6 Employer contribution 0.9 10.2 Settlements — (2.0 ) Benefits paid (0.9 ) (1.1 ) Expenses paid (0.1 ) — Foreign currency exchange rate changes 0.2 0.1 Fair value of plan assets at end of year $ 25.3 $ 21.7 Funded status $ (6.8 ) $ (6.3 ) The Company’s defined benefit pension plan for U.S. Sealy employees is underfunded. As of December 31, 2017 , the projected benefit obligation and fair value of plan assets were $28.3 million and $21.0 million , respectively. As of December 31, 2016 , the projected benefit obligation and fair value of plan assets were $24.9 million and $18.6 million , respectively. As of December 31, 2017 , the projected benefit obligation and fair value of plan assets for the Sealy Canada Ltd. pension plan were $3.8 million and $4.3 million , respectively. As of December 31, 2016 , the projected benefit obligation and fair value of plan assets for the Sealy Canada Ltd. pension plan were $3.1 million and $3.1 million , respectively. The accumulated benefit obligation for all pension plans was $32.1 million at December 31, 2017 and $28.0 million at December 31, 2016 . The following table represents amounts recorded in the Consolidated Balance Sheets: December 31, (in millions) 2017 2016 Amounts recognized in the Consolidated Balance Sheets: Non-current benefit liability $ 7.3 $ 6.3 Non-current benefit asset 0.5 — The following assumption, calculated on a weighted-average basis, was used to determine benefit obligations for the Company’s defined benefit pension plans as of December 31: 2017 2016 Discount rate (a) 3.56 % 4.06 % (a) The discount rates used in 2017 to determine the expenses for the U.S. retirement plan and Canadian retirement plan were 3.54% and 3.70% , respectively. The discount rates used in 2016 to determine the benefit obligations for the U.S. and Canadian defined benefit pension plans were 4.06% and 4.10% , respectively. No material amounts are expected to be reclassified from AOCL to be recognized as components of net income during 2018 . Plan Contributions and Expected Benefit Payments During 2018 , the Company expects to contribute $0.3 million to the Company's Plans from available cash and cash equivalents. The following table presents estimated future benefit payments: (in millions) Fiscal 2018 $ 1.0 Fiscal 2019 1.0 Fiscal 2020 1.1 Fiscal 2021 1.1 Fiscal 2022 1.2 Fiscal 2023 ‑ Fiscal 2027 7.0 Pension Plan Asset Information Investment Objective and Strategies The Company's investment objectives are to minimize the volatility of the value of the Company's pension assets relative to pension liabilities and to ensure assets are sufficient to pay plan benefits. Target and actual asset allocations are as follows: 2017 Target 2017 Common/collective trust consisting primarily of: Equity securities 60.00 % 76.47 % Debt securities 40.00 % 23.28 % Other — % 0.25 % Total plan assets 100.00 % 100.00 % Investment strategies and policies reflect a balance of risk-reducing and return-seeking considerations. The objective of minimizing the volatility of assets relative to liabilities is addressed primarily through asset diversification. Assets are broadly diversified across many asset classes to achieve risk-adjusted returns that, in total, lower asset volatility relative to liabilities. The Company's policy to rebalance the Company's investment regularly ensures that actual allocations are in line with target allocations as appropriate. Strategies to address the goal of ensuring sufficient assets to pay benefits include target allocations to a broad array of asset classes that provide return, diversification and liquidity. The plan investment fiduciaries are responsible for setting asset allocation targets, and monitoring asset allocation and investment performance. The Company’s pension investment manager has discretion to manage assets to ensure compliance with the asset allocations approved by the plan fiduciaries. Significant Concentrations of Risk Significant concentrations of risk in the Company's plan assets relate to equity, interest rate, and operating risk. In order to ensure assets are sufficient to pay benefits, a portion of plan assets is allocated to equity investments that are expected, over time, to earn higher returns with more volatility than fixed income investments which more closely match pension liabilities. Within the common/collective trusts, the plan assets contain no significant concentrations of risk related to individual securities or industry sectors. In order to minimize asset volatility relative to the liabilities, a portion of the plan assets are allocated to fixed income investments that are exposed to interest rate risk. Rate increases will generally result in a decline in fixed income assets while reducing the present value of the liabilities. Conversely, rate decreases will increase fixed income assets, partially offsetting the related increase in the liabilities. Operating risks primarily include the risks of inadequate diversification and insufficient oversight. To mitigate this risk, investments are diversified across and within asset classes in support of investment objectives. Policies and practices to address operating risks include ongoing oversight, plan and asset class investment guidelines, and periodic reviews against these guidelines to ensure adherence. Expected Long-Term Return on Plan Assets The expected long-term return assumption at December 31, 2017 was 7.00% for the defined benefit pension plan for U.S. Sealy employees and 5.50% for the defined benefit pension plan for Sealy Canada, Ltd. The expected long-term return assumption is based on historical and projected rates of return for current and planned asset classes in the plan’s investment portfolio. The assumption considers various sources, primarily inputs from advisors for long-term capital market returns, inflation, bond yields, and other variables, adjusted for specific aspects of the Company's investment strategy by plan. The investments in plan assets primarily consist of common collective trusts and money market funds. Investments in common collective trusts and money market funds are valued at the net asset value ("NAV") per share or unit multiplied by the number of shares or units held as of the measurement date. The determination of NAV for the common/collective trusts includes market pricing of the underlying assets as well as broker quotes and other valuation techniques that represent fair value as determined by the respective administrator of the common/collective trust. Management has determined that the NAV is an appropriate estimate of the fair value of the common collective trusts at December 31, 2017 and 2016 , based on the fact that the common/collective trusts are audited and accounted for at fair value by the administrators of the respective common/collective trusts. The methods described above may produce a fair value that may not be indicative of net realizable value or reflective of future fair value. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the Consolidated Balance Sheet dates. The fair value of the Company’s plan assets at December 31 by asset category was as follows: (in millions) 2017 2016 Asset Category Common/collective trust U.S. equity $ 15.1 $ 12.5 International equity 4.2 3.7 Total equity based funds 19.3 16.2 Common/collective trust - fixed income 5.9 4.9 Money market funds 0.1 0.6 Total $ 25.3 $ 21.7 Multi‑Employer Benefit Plans Approximately 32.0% of the Company’s domestic employees are represented by various labor unions with separate collective bargaining agreements. Hourly employees working at nine of the Company’s domestic manufacturing facilities are covered by union sponsored retirement plans. Further, employees working at three of the Company’s domestic manufacturing facilities are covered by union sponsored health and welfare plans. These plans cover both active employees and retirees. Through the health and welfare plans, employees receive medical, dental, vision, prescription and disability coverage. The Company’s cost associated with these plans consists of periodic contributions to these plans based upon employee participation. The expense recognized by the Company for such contributions for the years ended December 31 was follows: (in millions) 2017 2016 2015 Multi‑employer retirement plan expense $ 4.3 $ 4.9 $ 5.0 Multi‑employer health and welfare plan expense 3.5 2.8 2.4 The risks of participating in multi‑employer pension plans are different from the risks of participating in single‑employer pension plans in the following respects: 1) contributions to the multi‑employer plan by one employer may be used to provide benefits to employees of other participating employers; 2) if a participating employer ceases its contributions to the plan, the unfunded obligations of the plan allocable to the withdrawing employer may be borne by the remaining participant employers; and 3) if the Company withdraws from the multi‑employer pension plans in which it participates, the Company may be required to pay those plans an amount based on its allocable share of the underfunded status of the plan. The following table presents information regarding the multi‑employer pension plans that are significant to the Company for the years ended December 31, 2017 and 2016 , respectively: Pension Fund EIN/Pension Plan Number Date of Plan Year-End Pension Protection Act (1) 2017 FIP/RP Status (2) Contributions of the Company 2017 Surcharge Imposed (3) Expiration Date Year Contributions to Plan Exceeded More than 5 Percent of Total Contributions (in millions) United Furniture Workers Pension Fund A (4) 13-5511877-001 2/28/17 Red Implemented $ 1.1 No 2020 2015, 2016, 2017 Pension Plan of the National Retirement Fund 13-6130178-001 12/31/16 Red Implemented $ 0.8 Yes, 10.0% 2019 N/A Central States, Southeast & Southwest Areas Pension Plan 36-6044243-001 12/31/16 Red Implemented $ 0.7 Yes, 10.0% 2018 N/A Pension Fund EIN/Pension Plan Number Date of Plan Year-End Pension Protection Act (1) 2016 FIP/RP Status (2) Contributions of the Company 2016 Surcharge Imposed (3) Expiration Date Year Contributions to Plan Exceeded More than 5 Percent of Total Contributions (in millions) United Furniture Workers Pension Fund A (4) 13-5511877-001 2/29/16 Red Implemented $ 1.2 Yes, 10.0% 2017 2014, 2015, 2016 Pension Plan of the National Retirement Fund 13-6130178-001 12/31/15 Red Implemented $ 1.3 Yes, 10.0% 2019 N/A Central States, Southeast & Southwest Areas Pension Plan 36-6044243-001 12/31/15 Red Implemented $ 0.3 Yes, 10.0% 2018 N/A (1) The Pension Protection Act of 2006 ranks the funded status of multi-employer pension plans depending upon a plan’s current and projected funding. A plan is in the Red Zone (Critical) if it has a current funded percentage of less than 65.0% . A plan is in the Yellow Zone (Endangered) if it has a current funded percentage of less than 80.0% , or projects a credit balance deficit within seven years. A plan is in the Green Zone (Healthy) if it has a current funded percentage greater than 80.0% and does not have a projected credit balance deficit within seven years. The zone status is based on the plan’s year end rather than the Company’s. The zone status listed for each plan is based on information that the Company received from that plan and is certified by that plan’s actuary for the most recent year available. (2) Funding Improvement Plan or Rehabilitation Plan as defined in the Employee Retirement Income Security Act of 1974 has been implemented or is pending.

Stockholders' Equity Note [Abstract]
Stockholders' (Deficit) Equity	Stockholders' Equity (Deficit) (a) Common Stock. Tempur Sealy International has 300.0 million authorized shares of common stock with $0.01 per share par value and 0.01 million authorized shares of preferred stock with $0.01 per share par value. The holders of the common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Subject to preferences that may be applicable to any outstanding preferred stock, holders of common stock are entitled to receive ratably such dividends as may be declared from time to time by the Board of Directors out of funds legally available for that purpose. In the event of liquidation, dissolution or winding up, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The Board of Directors is authorized, subject to any limitations prescribed by law, without further vote or action by the stockholders, to issue from time to time shares of preferred stock in one or more series. Each such series of preferred stock will have such number of shares, designations, preferences, voting powers, qualifications, and special or relative rights or privileges as determined by the Board of Directors, which may include, among others, dividend rights, voting rights, redemption and sinking fund provisions, liquidation preferences, conversion rights and preemptive rights. (b) Shareholder Rights Agreement. On February 8, 2017, the Board of Directors of the Company authorized and declared a dividend distribution of one right (a “Right”) for each outstanding share of common stock, par value $0.01 per share (the “Common Shares”), of the Company to stockholders of record at the close of business on February 20, 2017. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share (the “Preferred Shares”), of the Company at an exercise price of $90 per one one-thousandth of a Preferred Share, subject to adjustment. Generally, the Rights become exercisable in the event any person or group (including a group of persons that are acting in concert with each other) acquires 20% or more of the Common Shares without the approval of the Board of Directors, and until such time are inseparable from and trade with the Company's Common Shares. The Rights have a de minimis fair value. The Rights are issued pursuant to the Amended and Restated Rights Agreement dated as of March 14, 2017 ("Amended Rights Agreement"), between the Company and American Stock Transfer & Trust Company, LLC, the Company's rights agent.

Stock-based Compensation

Stock-based Compensation	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based Compensation	Stock-based Compensation Tempur Sealy International has two stock-based compensation plans which provide for grants of non-qualified and incentive stock options, stock appreciation rights, restricted stock and stock unit awards, performance shares, stock grants and performance based awards to employees, non-employee directors, consultants and Company advisors. The plan under which equity awards may be granted in the future is the Amended and Restated 2013 Equity Incentive Plan (the "2013 Plan"). It is the policy of the Company to issue stock out of treasury shares upon issuance or exercise of share-based awards. The Company believes that awards and purchases made under these plans better align the interests of the plan participants with those of its stockholders. On May 11, 2017, the Company's stockholders approved the amendment and restatement of the original 2013 Plan. The 2013 Plan provides for grants of stock options to purchase shares of common stock to employees and directors of the Company. The 2013 Plan may be administered by the Compensation Committee of the Board of Directors, by the Board of Directors directly, or, in certain cases, by an executive officer or officers of the Company designated by the Compensation Committee. The shares issued or to be issued under the 2013 Plan may be either authorized but unissued shares of the Company’s common stock or shares held by the Company in its treasury. Tempur Sealy International may issue a maximum of 8.7 million shares of common stock under the 2013 Plan, subject to certain adjustment provisions. The Amended and Restated 2003 Equity Incentive Plan, as amended (the “2003 Plan”), was administered by the Compensation Committee of the Board of Directors, which, together with the Board of Directors, had the exclusive authority to administer the 2003 Plan, including the power to determine eligibility to receive awards, the types and number of shares of stock subject to the awards, the price and timing of awards and the acceleration or waiver of any vesting and performance of forfeiture restrictions, in each case subject to the terms of the 2003 Plan. Any of the Company’s employees, non-employee directors, consultants and Company advisors, as determined by the Compensation Committee, were eligible to be selected to participate in the 2003 Plan. Tempur Sealy International allowed a maximum of 11.5 million shares of its common stock under the 2003 Plan to be issued. In May 2013, the Company's Board of Directors adopted a resolution that prohibited further grants under the 2003 Plan. In 2010, the Board of Directors approved the terms of a Long-Term Incentive Plan established under the 2003 Plan. In 2013, the Board of Directors approved the terms of another Long-Term Incentive Plan established under the 2013 Plan. Awards under both Long-Term Incentive Plans have typically consisted primarily of a mix of stock options, RSUs and PRSUs. Shares with respect to the PRSUs will be granted and vest following the end of the applicable performance period and achievement of applicable performance metrics as determined by the Compensation Committee of the Board of Directors. The Company’s stock-based compensation expense for the year ended December 31, 2017 included PRSUs, stock options, RSUs and DSUs. A summary of the Company’s stock-based compensation expense is presented below: Year Ended December 31, (in millions) 2017 2016 2015 PRSU (benefit) expense $ (6.5 ) $ 3.9 $ 13.7 Stock option expense 7.1 5.3 6.6 RSU/DSU expense 12.7 7.0 2.2 Total stock-based compensation expense $ 13.3 $ 16.2 $ 22.5 The Company granted PRSUs during the years ended December 31, 2017 , 2016 and 2015 . Actual payout under the PRSUs is dependent upon the achievement of certain financial goals. The Company recorded a benefit in the accompanying Consolidated Statements of Income of $9.3 million and $3.8 million for the years ended December 31, 2017 and 2016 after the change in estimate to reduce accumulated performance based stock compensation amortization to actual cost based on updated projected or final financial results. Performance Restricted Stock Units A summary of the Company’s PRSU activity and related information for the years ended December 31, 2017 and 2016 is presented below: (shares in millions) Shares Weighted Average Grant Date Fair Value Awards unvested at December 31, 2015 1.9 $ 68.17 Granted 0.2 60.78 Vested (0.1 ) 51.87 Forfeited (0.3 ) 70.43 Awards unvested at December 31, 2016 1.7 68.02 Granted 1.6 59.64 Vested (0.2 ) 59.39 Forfeited (0.4 ) 65.48 Awards unvested at December 31, 2017 2.7 $ 64.13 During 2017, the Company granted executive officers and certain members of management PRSUs if the Company achieves a certain level of adjusted earnings before interest, tax, depreciation and amortization ("Adjusted EBITDA") during four consecutive fiscal quarters as described below (the "2019 Aspirational Plan PRSUs"). Adjusted EBITDA is defined as the Company’s "Consolidated EBITDA" as such term is defined in the Company’s 2016 Credit Agreement. The 2019 Aspirational Plan PRSUs will vest based on the highest Adjusted EBITDA in any four consecutive fiscal quarter period ending between (and including) March 31, 2018 and December 31, 2019 (the “First Designated Period”). If the highest Adjusted EBITDA in the First Designated Period is $600.0 million , 66% will vest; if the highest Adjusted EBITDA equals or exceeds $650.0 million , then 100% will vest; if the highest Adjusted EBITDA is between $600.0 million and $650.0 million then a pro rata portion will vest; and if the highest Adjusted EBITDA is less than $600.0 million then one-half of the 2019 Aspirational Plan PRSUs will no longer be available for vesting based on performance and the remaining one-half will remain available for vesting based on the highest Adjusted EBITDA in any four consecutive fiscal quarter period ending between (and including) March 31, 2020 and December 31, 2020 (the “Second Designated Period”). If the highest Adjusted EBITDA in the Second Designated Period is $600.0 million then 66% of the remaining 2019 Aspirational Plan PRSUs will vest; if the Adjusted EBITDA is $650.0 million or more 100% will vest; if Adjusted EBITDA is between $600.0 million and $650.0 million then a pro rata portion will vest; and if Adjusted EBITDA is below $600.0 million then all of the remaining 2019 Aspirational Plan PRSUs will be forfeited. The Company did not record any stock-based compensation expense related to the 2019 Aspirational Plan PRSUs during the year ended December 31, 2017 , as it is not considered probable that the Company will achieve the specified performance target for either the First Designated Period or Second Designated Period. The Company will continue to evaluate the probability of achieving the performance condition in future periods and record the appropriate expense if necessary. Based on the price of the Company’s common stock on the grant date, the total unrecognized compensation expense related to this award if the performance target is met for the First Designated Period is $85.5 million , which would be expensed over the remaining service period if achievement of the performance condition becomes probable. As of December 31, 2017 , the Company has 1.1 million PRSUs outstanding that will vest if the Company achieves more than $650.0 million of Adjusted EBITDA for 2017 (the " 2017 Aspirational Plan PRSUs"). Adjusted EBITDA is defined as the Company’s "Consolidated EBITDA" as such term is defined in the Company’s 2012 Credit Agreement. The Company expects that in early March 2018 the Compensation Committee of the Board of Directors will formally determine that the Company did not have more than $650.0 million in Adjusted EBITDA for 2017. As a result, two-thirds of the total 2017 Aspirational Plan PRSUs will be forfeited as of this date. The remaining one-third of the total 2017 Aspirational Plan PRSUs will vest if the Company achieves more than $650.0 million in Adjusted EBITDA for 2018 . All remaining 2017 Aspirational Plan PRSUs will be forfeited if the performance metric is not met in 2018. The Company did not record any stock-based compensation expense related to the 2017 Aspirational Plan PRSUs during the years ended December 31, 2017 and 2016 , as it is not considered probable that the Company will achieve the specified performance target as of December 31, 2017 or December 31, 2018 . The Company will continue to evaluate the probability of achieving the performance condition in future periods and record the appropriate expense if necessary. Based on the price of the Company’s common stock on the grant date, the total unrecognized compensation expense related to this award if the performance target is met for 2017 is $74.7 million , which would be expensed over the remaining service period if achievement of the performance condition becomes probable. As of December 31, 2017 , the Company has 0.2 million PRSUs outstanding that will vest if the Company achieves certain financial metrics over the three year performance period that ended December 31, 2017. The Company expects that in early March 2018, the Compensation Committee of the Board of Directors will formally determine that the Company did not meet the financial metrics for 2017. As a result, these PRSUs will be forfeited as of this date. During the year ended December 31, 2017 , shares granted in 2014 with an aggregate intrinsic value of $2.9 million were paid out from treasury stock following the satisfaction of certain financial metrics over the three year performance period that ended December 31, 2016. The PRSUs were paid out from treasury stock at 71.2% of the target award, out of a maximum potential payout of 300% . During the year ended December 31, 2016, shares granted in 2014 with an aggregate intrinsic value of $5.6 million were paid out from treasury stock following the satisfaction of certain financial metrics over the two year performance period that ended December 31, 2015. The PRSUs were paid out from treasury stock at 79.0% of the target award, out of a maximum potential payout of 200% . The aggregate intrinsic value of PRSUs outstanding as of December 31, 2017 was $173.6 million . Stock Options The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock options granted. During the year ended December 31, 2016 , no stock options were granted. The assumptions used in the Black-Scholes option-pricing model for the years ended December 31, 2017 , 2016 and 2015 are set forth in the following table. Expected volatility is based on the unbiased standard deviation of Tempur Sealy International’s common stock over the option term. The expected life of the options represents the period of time that the Company expects the options granted to be outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant of the option for the expected term of the instrument. The dividend yield reflects an estimate of dividend payouts over the term of the award. During 2017, the Company adopted a change in accounting policy to recognize forfeitures of awards as they occur instead of estimating potential forfeitures. Historically, the Company estimated the number of awards expected to be forfeited and adjusted the estimate when it was no longer probable that employees would fulfill their service conditions. The Company uses historical data to determine these assumptions. Year Ended December 31, 2017 2016 2015 Expected volatility range of stock 37.4% - 40.8% N/A 34.0% - 36.2% Expected life of option, range in years 5 N/A 3 - 5 Risk-free interest range rate 1.8% - 1.9% N/A 0.9% - 1.5% Expected dividend yield on stock 0.0% - 0.0% N/A 0.0% - 0.0% A summary of the Company’s stock option activity under the 2003 Plan and 2013 Plan for the years ended December 31, 2017 and 2016 is presented below: (in millions, except per share amounts and years) Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Options outstanding at December 31, 2015 2.1 $ 42.75 Granted — — Released (0.6 ) 24.72 Forfeited — 58.37 Options outstanding at December 31, 2016 1.5 $ 50.46 Granted 0.6 69.04 Released (0.3 ) 38.44 Forfeited (0.1 ) 67.45 Options outstanding at December 31, 2017 1.7 $ 58.93 6.98 $ 1.5 Options exercisable at December 31, 2017 0.9 $ 51.57 5.66 $ 10.2 The aggregate intrinsic value of options exercised during the years ended December 31, 2017 , 2016 and 2015 was $5.4 million , $23.9 million and $71.8 million , respectively. Cash received from options exercised under all stock-based compensation plans, including cash received from options issued from treasury shares, for the years ended December 31, 2017 , 2016 and 2015 , was $12.8 million , $15.7 million , and $20.4 million , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies (a) Lease Commitments . The Company has various operating leases that call for annual rental payments due in equal monthly installments and a lease with a rent free occupancy period. The Company’s policy is to recognize expense for lease payment, including those with escalating provisions and rent free periods, on a straight-line basis over the lease term. Operating lease expenses were $41.6 million , $33.5 million , and $41.4 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Future minimum lease payments at December 31, 2017 under these non-cancelable leases are as follows: (in millions) Year Ended December 31, 2018 $ 39.5 2019 29.6 2020 22.5 2021 20.1 2022 15.5 Thereafter 40.1 $ 167.3 The Company has the option to renew certain plant operating leases, with the longest renewal period extending through 2043. Certain of the operating leases provide for increased rent through increases in general price levels. The Company recognizes rent expense in these situations on a straight-line basis over the lease term. (b) Purchase Commitments . The Company will, from time to time, enter into limited purchase commitments for the purchase of certain raw materials. Amounts committed under these programs are not significant to the Company as of December 31, 2017 and 2016 . (c) David Buehring, Individually and on Behalf of All Others Similarly Situated v. Tempur Sealy International, Inc., Scott L. Thompson, and Barry A. Hytinen, filed March 24, 2017. On March 24, 2017, a suit was filed against Tempur Sealy International, Inc. and two of its officers in the U.S. District Court for the Southern District of New York, purportedly on behalf of a proposed class of stockholders who purchased Tempur Sealy common stock between July 28, 2016 and January 27, 2017. The complaint alleges that the Company made materially false and misleading statements regarding its then existing and future financial prospects, including those with one of its retailers, Mattress Firm, allegedly in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The Company does not believe the claims have merit and intends to vigorously defend against these claims. A Motion to Dismiss the case was filed by the Company on October 5, 2017. The plaintiffs filed their opposition to the Motion to Dismiss on November 20, 2017, and the Company filed its reply on December 21, 2017. The Court has not yet ruled on the Company’s Motion to Dismiss. The case is still in the early stages of litigation and there has been no discovery in the case. As a result, the outcome of the case is unclear and the Company is unable to reasonably estimate the possible loss, or range of loss, if any. Accordingly, the Company can give no assurance that this matter will not have a material adverse effect on the Company’s financial position or results of operations. (d) Myla Gardner v. Scott L.

Each complaint alleges that the Board of Directors and officers caused the Company to make materially false and misleading statements regarding its business and financial prospects, including those with one of its retailers, Mattress Firm, which was a violation of the fiduciary duties they owed to the Company. The Company does not believe any of the suits have merit and intends to vigorously defend against the claims in each case. The Plaintiffs in each of the cases have agreed to stay their respective actions until after a decision is rendered on the Motion to Dismiss in the Buehring action noted above. These cases are in the early stages of litigation, and as a result the outcome of each case is unclear, so the Company is unable to reasonably estimate the possible loss, or range of loss, if any. (e) Mattress Firm, Inc. v. Tempur-Pedic North America, LLC and Sealy Mattress Company, filed March 30, 2017. On March 30, 2017, a suit was filed against Tempur-Pedic North America, LLC and Sealy Mattress Company ( two wholly-owned subsidiaries of the Company) in the District Court of Harris County, Texas by Mattress Firm. The complaint alleges breach of contract, tortious interference and seeks a declaratory judgment with respect to the interpretation of its agreements with the Company. On April 7, 2017, the Company's subsidiaries named above, among others, filed suit against Mattress Firm in the U.S. District Court for the Southern District of Texas, Houston Division, seeking injunctive relief and damages for trademark infringement, unfair competition and trademark dilution in violation of the Lanham Act, and breach of contract and other state law violations. The complaint alleges that Mattress Firm violated the parties' transition agreements dated January 30, 2017, and consequently, federal and state law, by its use of the Company’s trademarks after April 3, 2017. On April 28, 2017, the complaint was amended to add a claim by Sealy Mattress Company for nonpayment by Mattress Firm for products sold and delivered. On May 23, 2017, the complaint was further amended to add allegations that Mattress Firm continued to use the Company’s trade names and trademarks on its website and in advertising in an inappropriate manner. On July 11, 2017, the Court issued a preliminary injunction prohibiting Mattress Firm from using the Company’s names and marks in such manner. On July 17, 2017, the complaint was further amended to add allegations that despite representations to the contrary, Mattress Firm continued to use the Company’s trade names and trademarks on its website and in advertising. On July 31, 2017, the complaint was further amended to address false and misleading advertising by Mattress Firm in the form of a YouTube video in violation of federal and state law, and in violation of the agreements between the parties. On December 7, 2017, the complaint was further amended to address false and misleading advertising by Mattress Firm through their Dare to Compare advertising campaign. Discovery is proceeding in both the Texas District Court case filed by Mattress Firm and the U.S. District Court case filed by the Company’s subsidiaries. The Company does not believe the claims asserted by Mattress Firm have merit and intends to vigorously defend against them. The cases are still in the early stages of litigation, and as a result, the outcome remains unclear so the Company is unable to reasonably estimate the possible loss, or range of loss, if any. Accordingly, the Company can give no assurance that these matters will not have a material adverse effect on the Company’s financial position or results of operations. (f) Other. The Company is involved in various other legal proceedings incidental to the operations of its business. The Company believes that the outcome of all such other pending legal proceedings in the aggregate will not have a material adverse effect on its business, financial condition, liquidity, or operating results.

Income Taxes

Income Taxes	12 Months Ended
	Dec. 31, 2017
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act of 2017 (public law 115-97, the “U.S. Tax Reform Act”). The U.S. Tax Reform Act reduces the U.S. federal corporate income tax rate from 35% to 21%. The U.S. Tax Reform Act implements a new territorial tax system that imposes a one-time transition tax, or deemed repatriation, on the earnings and profits of the Company’s controlled and non-controlled foreign subsidiaries to the extent such earnings and profits have not previously been subject to U.S. income tax (the “Transition Tax”). The amount subject to tax is reduced pursuant to the U.S. Tax Reform Act by a dividend received deduction, and as such, the amount that is taxable is substantially less than the amount of previously untaxed earnings and profits. The amount of the Transition Tax is based in part on the amount of earnings held by the foreign subsidiaries in cash and other specified assets. While the effective date of the new corporate tax rates for the Company is January 1, 2018, the Company is required to calculate the effects of changes in tax rates and laws on deferred tax balances in 2017, the period in which the legislation was enacted. For the year-ended December 31, 2017, enactment of the U.S. Tax Reform Act resulted in the following impacts to income tax provision: Remeasurement of deferred taxes The remeasurement of deferred tax assets and liabilities at the lower enacted U.S. federal corporate tax rate resulted in a net benefit to income tax provision of approximately $69.7 million for the year ended December 31, 2017, which represents a benefit to the Company’s effective income tax rate of approximately 37.0% . The reduction in the federal income tax rate indirectly impacted the Company’s state income tax rate applicable to its state deferred income tax assets and liabilities to the extent such items are reported net of federal income tax expense or benefit. The applicable combined income tax rate used to measure the deferred income tax assets and liabilities of the U.S. companies in the consolidated group at December 31, 2017 and 2016 was approximately 25.7% and 39.0% , respectively. Transition tax The Transition Tax resulted in a $45.9 million increase in income tax expense for the year ended December 31, 2017, which represents an increase to the Company’s effective tax rate of approximately 24.4% . Global Intangible Low-Taxed Income The U.S. Tax Reform Act subjects U.S. taxpayers to current tax on “global intangible low-taxed income” (“GILTI”) of its controlled foreign corporations. GAAP provides that a taxpayer may elect to either record a charge for the GILTI tax in a future period to the extent such tax arises in that period, or to record the future impact to the taxpayer of GILTI as part of deferred taxes related to its controlled foreign corporations. The Company is evaluating the accounting for the effects of the GILTI tax law provisions. Such evaluation is not yet complete. As such, the Company has not yet made an accounting policy election with respect to GILTI. The estimated impacts of the U.S. Tax Reform Act recorded during the year ended December 31, 2017 are provisional in nature, and the Company will continue to assess the impact of the U.S. Tax Reform Act and will record adjustments through the income tax provision in the relevant period as authoritative guidance is made available to the public. In addition, in reflecting the impact of the U.S. Tax Reform Act in the Company’s 2017 consolidated financial statements it was necessary to, in some cases, make estimates of one or more items to calculate such impact during the measurement period. Accordingly, the impact of the U.S. Tax Reform Act may differ from the Company's provisional estimates due to and among other factors, information currently not available, changes in interpretations and the issuance of additional guidance, as well as changes in assumptions the Company has currently made, including actions the Company may take in future periods as a result of the U.S. Tax Reform Act. In particular, there is currently a lack of clarity regarding the application of the executive compensation deduction limitations and state tax implications as a result of the U.S. Tax Reform Act. The Company currently estimates that the effect of the U.S. Tax Reform Act on executive compensation deduction limitations will primarily be effective in future periods. With regard to state tax implications, the Company generally expects state taxable income will increase as a result of deduction limitations associated with the U.S. Tax Reform Act, though the impact is not currently reasonably estimable as most U.S. state tax jurisdictions have not responded to the specific effects of the U.S. Tax Reform Act. The Company will make relevant updates to management's estimates and assumptions as additional information becomes available. The following sets forth the amount of income before income taxes attributable to each of the Company’s geographies for the years ended December 31, 2017, 2016 and 2015: Year Ended December 31, (in millions) 2017 2016 2015 Income before income taxes: United States $ 97.2 $ 179.0 $ 120.2 Rest of the world 91.2 92.8 70.9 $ 188.4 $ 271.8 $ 191.1 The Company’s effective income tax provision differs from the amount calculated using the statutory U.S. federal income tax rate, principally due to the following: Year Ended December 31, 2017 2016 2015 (dollars in millions) Amount Percentage of Income Before Income Taxes Amount Percentage of Income Amount Percentage of Income Statutory U.S. federal income tax $ 65.9 35.0 % $ 95.1 35.0 % $ 66.9 35.0 % State income taxes, net of federal benefit (0.6 ) (0.3 )% 8.0 2.9 % 1.1 0.6 % Foreign repatriation, net of foreign tax credits — — (4.3 ) (1.6 )% — — Foreign tax differential (11.6 ) (6.1 )% (11.9 ) (4.4 )% (10.0 ) (5.2 )% Change in valuation allowances 8.3 4.4 % 20.2 7.4 % 2.5 1.3 % Uncertain tax positions 0.2 0.0 % (27.1 ) (9.9 )% 59.7 31.2 % Subpart F income 2.7 1.4 % 2.0 0.7 % 1.9 1.0 % Manufacturing deduction (1.9 ) (1.0 )% (4.2 ) (1.5 )% (1.6 ) (0.8 )% Remeasurement of deferred taxes (69.7 ) (37.0 )% — — — — Transition Tax 45.9 24.4 % — — — — Permanent and other 8.5 4.5 % 9.0 3.3 % 4.9 2.5 % Effective income tax provision $ 47.7 25.3 % $ 86.8 31.9 % $ 125.4 65.6 % Subpart F income represents interest and royalties earned by a foreign subsidiary as well as sales made by certain foreign subsidiaries outside of their country of incorporation and is taxable to Tempur Sealy International as if earned directly by Tempur Sealy International. The Transition Tax represents taxes on certain foreign sourced earnings and profits that were previously tax deferred. The income tax provision consisted of the following: Year Ended December 31, (in millions) 2017 2016 2015 Current provision Federal $ 73.5 $ 73.5 $ 107.1 State 3.1 4.5 7.2 Foreign 31.3 39.9 32.4 Total current $ 107.9 $ 117.9 $ 146.7 Deferred provision Federal $ (67.7 ) $ (21.4 ) $ (12.3 ) State 7.5 1.6 (3.7 ) Foreign — (11.3 ) (5.3 ) Total deferred (60.2 ) (31.1 ) (21.3 ) Total income tax provision $ 47.7 $ 86.8 $ 125.4 The income tax provision includes federal, state, and foreign income taxes currently payable and those deferred or prepaid because of temporary differences between financial statement and tax bases of assets and liabilities. The Company records income taxes under the liability method. Under this method, deferred income taxes are recognized for the estimated future tax effects of differences between the tax bases of assets and liabilities and their financial reporting amounts based on enacted tax laws. The amount provided for deferred income taxes reflects that impact of the revaluation of the Company's deferred income tax assets and liabilities required as the result of the change in the U.S. federal and state income tax rates, as discussed above. The net deferred tax assets and liabilities recognized in the accompanying Consolidated Balance Sheets, determined using the income tax rate applicable to each period, consist of the following: December 31, (in millions) 2017 2016 Deferred tax assets: Stock-based compensation $ 10.6 $ 18.4 Accrued expenses and other 36.3 49.9 Net operating losses, foreign tax credits and other tax attribute carryforwards 92.9 98.5 Inventories 6.2 7.2 Transaction costs 13.4 10.2 Property, plant and equipment 2.8 3.4 Total deferred tax assets 162.2 187.6 Valuation allowances (55.1 ) (45.2 ) Total net deferred tax assets $ 107.1 $ 142.4 Deferred tax liabilities: Intangible assets $ (161.9 ) $ (242.4 ) Property, plant and equipment (29.5 ) (42.4 ) Accrued expenses and other (6.4 ) (9.7 ) Total deferred tax liabilities (197.8 ) (294.5 ) Net deferred tax liabilities $ (90.7 ) $ (152.1 ) No additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the Transition Tax, or any additional outside basis differences inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations. At December 31, 2017, the Company’s tax basis in its top tier foreign subsidiary exceeded the Company’s book basis in this subsidiary in the hands of the top tier foreign subsidiary's U.S. shareholder. The Company has not recorded a deferred tax asset on such excess tax basis as it is not apparent that the excess tax basis will reverse in the foreseeable future. As it relates to the book to tax basis difference with respect to the stock of each of the Company’s lower tier foreign subsidiaries, as a general matter, the book basis exceeds the tax basis in the hands of such foreign subsidiaries' shareholders. By operation of the tax laws of the various countries in which these subsidiaries are domiciled, earnings of lower tier foreign subsidiaries are not subject to tax, in all material respects, when distributed to a foreign shareholder. It is the Company’s intent that the earnings of each lower tier foreign subsidiary, with the exception of its Danish subsidiary and one of its Canadian subsidiaries, will be permanently reinvested in each such foreign subsidiaries' own operations. As it relates to the Danish subsidiary, its earnings may be distributed without any income tax impact. Thus, no tax is provided for with respect to the book to tax basis difference of its stock. With respect to the Canadian subsidiary, Canadian income tax withholding applies to any distribution it makes to its foreign parent company. At December 31, 2017, the Company has concluded that the Canadian subsidiary does not have accumulated earnings in excess of its operating needs. As such no Canadian withholding tax has been accrued at December 31, 2017. The Company has the following gross income tax attributes available at December 31, 2017 and 2016 , respectively: (in millions) 2017 2016 State net operating losses (“SNOLs”) $ 133.9 $ 131.2 U.S. federal foreign tax credits (“FTCs”) 12.2 12.2 U.S. state income tax credits ("SITCs") 8.1 4.0 Foreign net operating losses (“FNOLs”) 33.1 34.1 Charitable contribution carryover ("CCCs") 18.0 38.4 The SNOLs, FTCs, SITCs, FNOLs and CCCs generally expire in 2021, 2023, 2023, 2023 and 2020, respectively. Management believes that, based on a number of factors, the available objective evidence creates sufficient uncertainty regarding the realizability of certain of the SNOLs, FTCs, SITCs, FNOLs, CCCs and certain other deferred tax assets related to certain foreign operations (together, the “Tax Attributes”). In assessing the realizability of deferred tax assets (including the Tax Attributes), management considers whether it is more likely than not that some portion of all of such deferred tax assets will not be realized. Accordingly, the Company has established a valuation allowance for certain Tax Attributes. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the temporary differences become deductible or creditable. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. The Company has recorded valuation allowances against approximately $124.2 million of the SNOLs, $12.2 million of the FTCs, and $8.1 million of SITCs. With respect to all other tax attributes above, based upon the level of historical taxable income and projections for future taxable income, management believes it is more likely than not the Company will realize the benefits of the underlying deferred tax assets. However, there can be no assurance that such assets will be realized if circumstances change. GAAP prescribes a recognition threshold and measurement attribute for the accounting and financial statement disclosure of tax positions taken or expected to be taken in a tax return. The evaluation of a tax position is a two-step process. The first step requires the Company to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. The second step requires the Company to recognize in the financial statements each tax position that meets the more likely than not criteria, measured at the largest amount of benefit that has a greater than 50.0% likelihood of being realized. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: (in millions) Balance as of December 31, 2015 $ 69.8 Additions based on tax positions related to 2016 2.5 Additions for tax positions of prior years 29.2 Expiration of statutes of limitations (5.0 ) Settlements of uncertain tax positions with tax authorities (24.8 ) Balance as of December 31, 2016 $ 71.7 Additions based on tax positions related to 2017 3.9 Additions for tax positions of prior years 11.4 Expiration of statutes of limitations — Settlements of uncertain tax positions with tax authorities (2.5 ) Balance as of December 31, 2017 $ 84.5 The amount of unrecognized tax benefits that would impact the effective tax rate if recognized at December 31, 2017 , 2016 and 2015 would be $31.7 million, $21.4 million and $67.7 million , respectively. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense. During the years ended December 31, 2017 , 2016 and 2015 , the Company recognized approximately $0.4 million , $1.6 million , and $33.5 million in interest and penalties, respectively, in income tax expense. The Company had approximately $59.9 million , $52.3 million , and $43.8 million of accrued interest and penalties at December 31, 2017 , 2016 , and 2015 , respectively. The Company has received income tax assessments from the Danish Tax Authority ("SKAT") with respect to the tax years 2001 through 2008 relating to the royalty paid by a U.S. subsidiary of Tempur Sealy International to a Danish subsidiary (the "Danish Assessments"). The royalty is paid by the U.S. subsidiary for the right to utilize certain intangible assets owned by the Danish subsidiary in the U.S. production process. In its assessment, SKAT asserts that the amount of royalty rate paid by the U.S. subsidiary to the Danish subsidiary is not reflective of an arms-length transaction. Accordingly, the tax assessment received from SKAT is based, in part, on a 20% royalty rate, which is substantially higher than that historically used or deemed appropriate by the Company. The cumulative total tax assessment for the Danish Assessments at December 31, 2017 for all years for which an assessment has been received (2001 - 2008) is approximately Danish Krone ("DKK") 1,638.4 million , including interest and penalties ( $264.3 million , based on the DKK to USD exchange rate on December 31, 2017). The cumulative total tax assessment at December 31, 2016 for all years for which an assessment had been received up through that date (2001 - 2008), including interest and penalties, was approximately DKK 1,547.3 million ( $219.3 million , based on the DKK to USD exchange rate on December 31, 2016). If SKAT continues to issue assessments for each year not currently assessed, the Company expects the aggregate assessments for such years (2009 - 2017) to be in excess of the amounts described above as assessed for the years 2001 - 2008 (collectively the years 2001 through 2017 are referred to as the "Danish Tax Matter"). At December 31, 2017 and 2016, the Company had accrued Danish tax and interest for the Danish Tax Matter of approximately DKK 854 million and DKK 850 million respectively (approximately $137.8 million and $120.6 million using the December 31, 2017 and 2016 exchange rates, as applicable) as an uncertain income tax liability. Approximately DKK 835 million (approximately $134.8 million and $118.5 million using December 31, 2017 and 2016 exchange rates, as applicable) represents the amount that the Company and SKAT preliminarily agreed to in a non-binding proposed resolution for the years 2001 through 2011. The balance of approximately DKK 18 million and DKK 15 million (approximately $3.0 million and $2.1 million respectively using the December 31, 2017 and 2016 exchange rates, as applicable) may be subject to further negotiation in the future as part of an Advanced Pricing Agreement the Company may choose to pursue for years after 2011. The amount accrued is included in other non-current liabilities on the Company's Consolidated Balance Sheets. In addition, at December 31, 2017 and 2016 the Company had recorded a deferred tax asset of approximately $47.2 million and $43.5 million , respectively, for the U.S. correlative benefit related to this matter. At December 31, 2017 and 2016, the Company has recorded a valuation allowance with respect to this benefit of approximately $19.3 million and $17.6 million related to years for which relief may not be realized. Because the Company is in a net deferred tax liability position, the deferred tax asset referred to herein is netted with the Company’s deferred tax liabilities as reflected on the Consolidated Balance Sheets at December 31, 2017 and 2016. The Company’s uncertain tax liability associated with the Danish Tax Matter is derived using the cumulative probability analysis with possible outcomes based on the Company's updated evaluation of the facts and circumstances regarding this matter and applying the technical requirements applicable to U.S., Danish, and international transfer pricing standards as required by GAAP, taking into account both the U.S. and Danish income tax implications of such outcomes. Both the uncertain tax liability and the deferred tax asset discussed herein reflects the Company’s best judgment of the facts, circumstances and information available through December 31, 2017. If the Company is not successful in defending its position before the Danish National Tax Tribunal (the "Tribunal"), the appeals division within SKAT, or in the Danish courts or in negotiating a mutually acceptable settlement, there is significant risk that the Company could be required to pay a significant amount to SKAT in excess of any related reserve. Such an outcome could have a material adverse impact on the Company’s profitability and liquidity. In addition, prior to any ultimate resolution of this issue before the Tribunal or the Danish courts, based on a change in facts and circumstances, the Company may be required to further increase its uncertain tax liability associated with this matter, which could have a material impact on the Company's reported earnings. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense. It is reasonably possible that there could be material changes to the amount of uncertain tax positions due to activities of the taxing authorities, settlement of audit issues, reassessment of existing uncertain tax positions, including the Danish tax matter, or the expiration of applicable statute of limitations; however, the Company is not able to estimate the impact of these items at this time. From June 2012 through December 31, 2017, SKAT withheld Value Added Tax refunds otherwise owed to the Company, pending resolution of this matter. Total withheld refunds at December 31, 2017 and 2016 are approximately DKK 336.5 million (approximately $54.1 million ) and DKK 258.0 million (approximately $36.6 million ), respectively. In July 2016, the Company paid a deposit to SKAT in the amount of approximately DKK 615.2 (approximately $98.9 million and $87.2 million using the applicable exchange rates at December 31, 2017 and 2016, respectively) (the “Tax Deposit”) and applied approximately DKK 224.6 million (approximately $36.1 million and $31.8 million using the exchange rate at December 31, 2017 and 2016) of its Value Added Tax refund (the “VAT Refund Applied”) to the aforementioned potential Danish income tax liability, consistent with the Company’s reserve position for this royalty matter. The deposit was made to mitigate additional interest and foreign exchange exposure. The Tax Deposit and the VAT Refund Applied are included within other non-current assets on the Consolidated Balance Sheets. The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. In the quarter ended September 30, 2015, the Company was advised by the IRS that the federal income tax return for 2013 would be examined. That examination was settled and finalized in the fourth quarter of 2016 commensurate with the Company’s expectations. With few exceptions, the Company is no longer subject to tax examinations by the U.S. state and local municipalities for periods prior to 2011, and in non-U.S. jurisdictions for periods prior to 2001. Additionally, the Company is currently under examination by various tax authorities around the world. The Company anticipates it is reasonably possible an increase or decrease in the amount of unrecognized tax benefits could be made in the next twelve months as a result of the statute of limitations expiring and/or the examinations being concluded on these returns. However, the Company does not presently anticipate that any increase or decrease in unrecognized tax benefits will be material to the Consolidated Financial Statements. Other than the changes discussed in the preceding paragraphs, particularly as it relates to the Danish royalty matter, there were no significant changes to the liability for unrecognized tax benefits during the year ended December 31, 2017.

Non-controlling Interests

Noncontrolling Interest [Abstract]
Non-controlling Interests	Non-controlling Interest s The Company's call arrangement with Comfort Revolution may be exercised by the Company on December 31, 2019. The put arrangement may be exercised by Comfort Revolution on December 31, 2020. The redemption value for both the put and the call arrangement is equal to 7.5 times EBITDA, as defined in the related limited liability company ("LLC") agreement, of Comfort Revolution for the preceding 12 months, adjusted for net debt outstanding and multiplied by the 55.0% ownership interest not held by the Company. Due to the existing put and call arrangements, the non-controlling interest is considered to be redeemable and is recorded on the Consolidated Balance Sheets as a redeemable non-controlling interest outside of permanent equity. The redeemable non-controlling interest is recognized at the higher of 1) the accumulated earnings associated with the non-controlling interest or 2) the contractually-defined redemption value as of the balance sheet date. As of December 31, 2017 and 2016, the accumulated earnings exceeded the redemption value and, accordingly, a redemption value adjustment was not necessary. During the year ended December 31, 2016, the Company acquired 51% of the outstanding equity of an entity included in the North America segment with the remaining 49% representing non-controlling interest. The non-controlling interest was originally recorded at its acquisition date fair value in “Stockholders’ (deficit) equity” in the Consolidated Balance Sheets at December 31, 2016 as the non-controlling interest is not redeemable currently or in future periods. During the year ended December 31, 2017, the Company acquired the remaining 49% equity interest.

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information The Company operates in two segments: North America and International. Corporate operating expenses are not included in either of the segments and are presented separately as a reconciling item to consolidated results. These segments are strategic business units that are managed separately based on geography. The North America segment consists of Tempur and Sealy manufacturing and distribution subsidiaries, joint ventures and licensees located in the U.S. and Canada. The International segment consists of Tempur and Sealy manufacturing and distribution subsidiaries, joint ventures and licensees located in Europe, Asia-Pacific and Latin America. The Company evaluates segment performance based on net sales, gross profit and operating income. There were no customers that contributed more than 10% of the Company's sales in 2017 . Mattress Firm, previously a customer in the North America segment, represented 21.4% and 23.7% of the Company's sales for the year ended December 31, 2016, and 2015, respectively.

As described in Note 13 , "Income Taxes," during the fourth quarter of 2015, the Company recorded a change in estimate of its uncertain tax positions related to the Danish Tax Matter of approximately $60.7 million . In addition, in the third quarter of 2015 the Company recognized $9.5 million of other income from certain other non-recurring items, including the partial settlement of a legal dispute. In the first quarter of 2017, the Company recorded $25.9 million of net charges related to the termination of the relationship with Mattress Firm. As previously disclosed, in the third quarter of 2017, the Company recorded $11.7 million of charges related to a Latin American subsidiary. In the fourth quarter of 2017, the Company recorded $14.0 million of charges associated with this subsidiary. The Company has revised its financial statements for the fourth quarter of 2016 to record $11.5 million of charges associated with this subsidiary. The sum of the quarterly earnings per common share amounts may not equal the annual amount reported because per share amounts are computed independently for each quarter and for the full year based on respective weighted-average common shares outstanding and other dilutive potential common shares. The Company’s quarterly operating results fluctuate as a result of seasonal variations in the Company’s business.

Summary of Significant Accoun29

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation and Description of Business	Basis of Presentation and Description of Business. Tempur Sealy International, Inc., a Delaware corporation, together with its subsidiaries, is a U.S. based, multinational company. The term “Tempur Sealy International” refers to Tempur Sealy International, Inc. only, and the term “Company” refers to Tempur Sealy International, Inc. and its consolidated subsidiaries. The Company develops, manufactures, markets and sells bedding products, which include mattresses, foundations and adjustable bases, and other products, which include pillows and other accessories. The Company also derives income from royalties by licensing Sealy® and Stearns & Foster® brands, technology and trademarks to other manufacturers. The Company sells its products through two sales channels: Wholesale and Direct.
Basis of Consolidation	Basis of Consolidation. The accompanying financial statements include the accounts of Tempur Sealy International and its controlled subsidiaries and the results of Comfort Revolution, LLC ("Comfort Revolution"). Intercompany balances and transactions have been eliminated. Comfort Revolution is a 45.0% owned joint venture. Comfort Revolution constitutes a variable interest entity (“VIE”) for which the Company is considered to be the primary beneficiary due to the Company's disproportionate share of the economic risk associated with its equity contribution, debt financing and other factors that were considered in the related-party analysis surrounding the identification of the primary beneficiary. The Company is party to put and call arrangements with respect to the common securities that represent the 55.0% non-controlling interest in Comfort Revolution not owned by the Company. The operations of Comfort Revolution are not material to the Company’s Consolidated Financial Statements. The Company also has ownership interests in a group of Asia-Pacific joint ventures to develop markets for Sealy® branded products in those regions. The equity method of accounting is used for these joint ventures, over which the Company has significant influence but does not have effective control, and consolidation is not otherwise required. The Company’s equity in the net income and losses of these investments is reported in equity income in earnings of unconsolidated affiliates in the accompanying Consolidated Statements of Income.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Company’s results are affected by economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies and changes in the prices of raw materials, can have a significant effect on operations.
Fair Value Measurements	Fair Value Measurements. The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the Consolidated Financial Statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows: • Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets. • Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments. • Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements. The classification of fair value measurements within the established three-level hierarchy is based upon the lowest level of input that is significant to the measurements. There were no transfers between levels for the years ended December 31, 2017 or 2016 . The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term maturity of those instruments. The fair value of the Company's financial instruments that are recorded on a recurring basis at fair value is not material.
Foreign Currency	Foreign Currency. Assets and liabilities of non-U.S. subsidiaries, whose functional currency is the local currency, are translated into U.S. dollars at period-end exchange rates. Income and expense items are translated at the average rates of exchange prevailing during the period. The adjustments resulting from translating the financial statements of foreign subsidiaries are included in accumulated other comprehensive loss (“AOCL”), a component of stockholders’ equity/(deficit), and included in net earnings only upon sale or liquidation of the underlying foreign subsidiary or affiliated company. Foreign currency transaction gains and losses are recognized in net earnings based on differences between foreign exchange rates on the transaction date and on the settlement date. These amounts are not considered material to the Consolidated Financial Statements.
Derivative Financial Instruments	Derivative Financial Instruments. Derivative financial instruments are used in the normal course of business to manage interest rate and foreign currency exchange risks. The financial instruments used by the Company are straight-forward, non-leveraged instruments. The counterparties to these financial instruments are financial institutions with strong credit ratings. The Company maintains control over the size of positions entered into with any one counterparty and regularly monitors the credit ratings of these institutions. For all transactions designated as hedges, the hedging relationships are formally documented at the inception and on an ongoing basis in offsetting changes in cash flows of the hedged transaction. The Company records derivative financial instruments on the Consolidated Balance Sheets as either an asset or liability measured at its fair value. Changes in a derivative's fair value (i.e. unrealized gains or losses) are recorded each period in earnings or other comprehensive income ("OCI"), depending on whether the derivative is designated and is effective as a hedged transaction, and on the type of hedging relationship. For derivative financial instruments that are designated as a hedge, unrealized gains and losses related to the effective portion are either recognized in income immediately to offset the realized gain or loss on the hedged item, or are deferred and reported as a component of AOCL in stockholders' equity/(deficit) and subsequently recognized in net income when the hedged item affects net income. The change in fair value of the ineffective portion of a derivative financial instrument is recognized in net income immediately. For derivative instruments that are not designated as hedges, the gain or loss related to the change in fair value is also recorded to net income immediately. The effectiveness of the cash flow hedge contracts, including time value, is assessed prospectively and retrospectively on a monthly basis using regression analysis, as well as other timing and probability criteria. For derivative instruments that are not designated as hedges, the gain or loss related to the change in fair value is also recorded in net income immediately. The Company manages a portion of the risk associated with fluctuations in foreign currencies related to intercompany and third party inventory purchases denominated in foreign currencies through foreign exchange forward contracts designated as cash flow hedges. During 2017, the Company had foreign exchange forward contracts designated as cash flow hedges to buy U.S. dollars and to sell Canadian dollars. These foreign exchange forward contracts matured in September 2017. The forward exchange contract asset and liability as of December 31, 2016 and 2015 were based on Level 2 inputs and were not material in either period. The Company is also exposed to foreign currency risk related to intercompany debt and associated interest payments and certain intercompany accounts receivable and accounts payable. To manage the risk associated with fluctuations in foreign currencies related to these assets and liabilities, the Company enters into foreign exchange forward contracts. The Company considers these contracts to be economic hedges. Accordingly, changes in the fair value of these instruments affect earnings during the current period. These foreign exchange forward contracts protect against the reduction in value of forecasted foreign currency cash flows resulting from payments in foreign currencies.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash and cash equivalents consist of all highly liquid investments with initial maturities of three months or less. The carrying value of cash and cash equivalents approximates fair value because of the short-term maturity of those instruments.
Inventories	Inventories. Inventories are stated at the lower of cost or market, determined by the first-in, first-out method
Property, Plant and Equipment	Property, Plant and Equipment. Property, plant and equipment are carried at cost at acquisition date and are depreciated using the straight-line method over their estimated useful lives as follows: Estimated Useful Lives (in years) Buildings 25-30 Computer equipment and software 3-5 Leasehold improvements 4-7 Machinery and equipment 3-7 Office furniture and fixtures 5-7 The Company records depreciation and amortization in cost of sales for long-lived assets used in the manufacturing process, and within each line item of operating expenses for all other long-lived assets. Leasehold improvements are amortized over the shorter of the life of the lease or seven years. Assets under capital lease are included within property, plant and equipment and represent non-cash investing activities.
Long-Lived Assets	Long-Lived Assets. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets is assessed by a comparison of the carrying amount of the asset to the estimated future undiscounted net cash flows expected to be generated by the asset or group of assets. If estimated future undiscounted net cash flows are less than the carrying amount of the asset or group of assets, the asset is considered impaired and an expense is recorded in an amount required to reduce the carrying amount of the asset to its then fair value. Fair value generally is determined from estimated discounted future net cash flows (for assets held for use) or net realizable value (for assets held for sale).
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets. Intangible assets with finite useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment whenever events or changes in circumstances indicate impairment may have occurred. The Company performs an annual impairment test on goodwill and indefinite-lived intangible assets on October 1 of each year and whenever events or circumstances make it more likely than not that impairment may have occurred. In conducting the impairment test for the North America and International reporting units, the fair value of each of the Company's reporting units is compared to its respective carrying amount including goodwill. If the fair value exceeds the carrying amount, then no impairment exists. If the carrying amount exceeds the fair value, further analysis is performed to assess impairment. The Company’s determination of fair value of the reporting units is based on a discounted cash flow approach, with an appropriate risk-adjusted discount rate, and a market approach. Any identified impairment would result in an adjustment to the Company’s results of operations. The Company also tests its indefinite-lived intangible assets, principally the Tempur and Sealy trade names. The Company tested both trade names for impairment using a “relief-from-royalty” method. Significant assumptions inherent in the methodologies are employed and include such estimates as royalty and discount rates. The Company performed its annual impairment test of goodwill and indefinite-lived intangible assets in 2017 , 2016 and 2015 , and an interim impairment test for its North America reporting unit in March 2017, none of which resulted in the recognition of impairment charges. The most recent annual impairment tests performed as of October 1, 2017, indicated that the fair values of each of the Company's reporting units and indefinite-lived intangible assets were substantially in excess of their carrying values.
Accrued Sales Returns	Accrued Sales Returns. The Company allows product returns through certain sales channels and on certain products. Estimated sales returns are provided at the time of sale based on historical sales channel return rates. Estimated future obligations related to these products are provided by a reduction of sales in the period in which the revenue is recognized. The Company considers the impact of recoverable salvage value on sales returns by segment in determining its estimate of future sales returns.
Warranties	Warranties. The Company provides warranties on certain products, which vary based by segment, product and brand. Estimates of warranty expenses are based primarily on historical claims experience and product testing. Estimated future obligations related to these products are charged to cost of sales in the period in which the related revenue is recognized. In estimating its warranty obligations, the Company considers the impact of recoverable salvage value on warranty costs by segment in determining its estimate of future warranty obligations. The Company provides warranties on mattresses with varying warranty terms. Tempur mattresses sold in the North America segment and all Sealy mattresses have warranty terms ranging from 10 to 25 years, generally non-prorated for the first 10 to 15 years and then prorated for the balance of the warranty term. Tempur mattresses sold in the International segment have warranty terms ranging from 5 to 15 years, non-prorated for the first 5 years and then prorated on a straight-line basis for the last 10 years of the warranty term. Tempur pillows have a warranty term of 3 years, non-prorated.
Income Taxes	Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are also recognized for the estimated future effects of tax loss carry forwards. The effect of changes in tax rates on deferred taxes is recognized in the period in which the enactment dates change. The deferred tax assets and liabilities have been re-valued pursuant to the U.S. Tax Reform Act as discussed in Note 13 - Income Taxes . Valuation allowances are established when necessary on a jurisdictional basis to reduce deferred tax assets to the amounts expected to be realized. The Company accounts for uncertain foreign and domestic tax positions utilizing a proscribed recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.
Revenue Recognition	Revenue Recognition. Sales of products are recognized when persuasive evidence of an arrangement exists, title passes to customers and the risks and rewards of ownership are transferred, the sales price is fixed or determinable, and collectability is reasonably assured. The Company extends volume discounts to certain customers, as well as promotional allowances, floor sample discounts, commissions paid to retail associates and slotting fees, and reflects these amounts as a reduction of sales at the time revenue is recognized based on historical experience. The Company also reports sales net of tax assessed by qualifying governmental authorities. The Company extends credit based on the creditworthiness of its customers. No collateral is required on sales made in the normal course of business.
Allowance for Doubtful Accounts	The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company regularly reviews the adequacy of its allowance for doubtful accounts. The Company determines the allowance for doubtful accounts based on historical write-off experience and current economic conditions and also considers factors such as customer credit, past transaction history with the customer and changes in customer payment terms when determining whether the collection of a customer receivable is reasonably assured. Account balances are charged off against the allowance after all reasonable means of collection have been exhausted and the potential for recovery is considered remote.
Cost of Sales	Cost of Sales . Costs associated with net sales are recorded in cost of sales. Cost of sales includes the costs of receiving, producing, inspecting, warehousing, insuring, and shipping goods during the period, as well as depreciation and amortization of long-lived assets used in these processes. Cost of sales also includes shipping and handling costs associated with the delivery of goods to customers and costs associated with internal transfers between plant locations.
Cooperative Advertising, Rebate and Other Promotional Programs	Cooperative Advertising, Rebate and Other Promotional Programs. The Company enters into programs with customers to provide funds for advertising and promotions. The Company also enters into volume and other rebate programs with customers. When sales are made to these customers, the Company records liabilities pursuant to these programs. The Company periodically assesses these liabilities based on actual sales and claims to determine whether all of the cooperative advertising earned will be used by the customer or whether the customer will meet the requirements to receive rebate funds. The Company generally negotiates these programs on a customer-by-customer basis. Some of these agreements extend over several years. Significant estimates are required at any point in time with regard to the ultimate reimbursement to be claimed by the customers. Subsequent revisions to the estimates are recorded and charged to earnings in the period in which they are identified. Rebates and cooperative advertising are classified as a reduction of revenue and presented within net sales in the accompanying Consolidated Statements of Income. Certain cooperative advertising expenses are reported as components of selling and marketing expenses in the accompanying Consolidated Statements of Income because the Company receives an identifiable benefit and the fair value of the advertising benefit can be reasonably estimated.
Advertising Costs	Advertising Costs. The Company expenses advertising costs as incurred except for production costs and advance payments, which are deferred and expensed when advertisements run for the first time. Direct response advance payments are deferred and amortized over the life of the program. Advertising costs are included in selling and marketing expenses in the accompanying Consolidated Statements of Income. Advertising costs charged to expense were $284.1 million , $352.7 million and $360.5 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Advertising costs include expenditures for shared advertising costs that the Company reimburses to customers under its integrated and cooperative advertising programs. Cooperative advertising costs paid to customers are recorded as a component of selling and marketing expenses within the Consolidated Statements of Income to the extent of the estimated fair value of the customer's underlying advertisement when the customer provides proof of advertising. The Company periodically assesses the liabilities recorded for cooperative advertising based on actual sales and claims to determine whether all of the cooperative advertising earned will be used by the customer.
Research and Development Expenses	Research and Development Expenses. Research and development expenses for new products are expensed as they are incurred and are included in general, administrative and other expenses in the accompanying Consolidated Statements of Income.
Royalty Income and Expense	Royalty Income and Expense. The Company recognizes royalty income based on sales of Sealy® and Stearns & Foster® branded products by various licensees. The Company also pays royalties to other entities for the use of their names on products produced by the Company.
Stock-Based Compensation	Stock-based Compensation. The Company accounts for stock-based payment transactions in which the Company receives employee services in exchange for equity instruments of the Company. Stock-based compensation cost for restricted stock units (“RSUs”), performance restricted stock units (“PRSUs”) and deferred stock units (“DSUs”) is measured based on the closing fair market value of the Company’s common stock on the date of grant. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair value as calculated by the Black-Scholes option-pricing model. The Company recognizes stock-based compensation cost as expense for awards other than its PRSUs ratably on a straight-line basis over the requisite service period. The Company recognizes stock-based compensation cost associated with its PRSUs over the requisite service period if it is probable that the performance conditions will be satisfied.
Treasury Stock	Treasury Stock. Subject to Delaware law, and the limitations in the Company's 2016 Credit Agreement (as defined in Note 7 , "Debt") and the Company's other debt agreements, the Board of Directors may authorize share repurchases of the Company’s common stock (“Stock Repurchase Authorizations”). Purchases made pursuant to Stock Repurchase Authorizations may be carried out through open market transactions, negotiated purchases or otherwise, at times and in such amounts as the Company deems appropriate. Stock repurchased under Stock Repurchase Authorizations is held in treasury for general corporate purposes, including issuances under various employee stock-based award plans. On February 1, 2016, the Board of Directors authorized a stock repurchase program pursuant to which the Company was authorized to repurchase shares of Tempur Sealy International's common stock. For the year ended December 31, 2017 , the Company repurchased 0.6 million shares for approximately $40.1 million under the share repurchase authorization. As of December 31, 2017 , the Company had approximately $226.9 million remaining under the existing share repurchase authorization. In addition, the Company acquired 0.1 million and 0.0 million shares upon the vesting of certain PRSUs, which were withheld to satisfy tax withholding obligations during the year ended December 31, 2017 and 2016 , respectively. The shares withheld were valued at the closing price of the common stock on the New York Stock Exchange on the vesting date or last business day prior to the vesting date, resulting in approximately $4.8 million and $2.0 million in treasury stock acquired during the year ended December 31, 2017 and 2016 , respectively. Treasury stock is accounted for under the cost method and reported as a reduction of stockholders’ equity/(deficit). Stock Repurchase Authorizations may be suspended, limited or terminated at any time without notice.
Self-Insurance	Self-Insurance. The Company is self-insured up to $0.8 million per claim per year for certain losses related to medical claims with excess loss coverage. The Company also utilizes large deductible policies to insure claims related to general liability, product liability, automobile, and workers’ compensation. The Company’s recorded liability for workers’ compensation represents an estimate of the ultimate cost of claims incurred as of the Consolidated Balance Sheet date. The estimated workers' compensation liability is undiscounted and is established based upon analysis of historical and actuarial estimates, and is reviewed by the Company and third party actuaries on a quarterly basis to ensure that the liability is appropriate. As of December 31, 2017 and 2016 , $4.8 million and $8.6 million , respectively, of the recorded undiscounted liability is included in accrued expenses and other current liabilities and $15.9 million and $12.3 million , respectively, is included in other non-current liabilities within the accompanying Consolidated Balance Sheets. During 2016, the Company entered into a retroactive insurance policy to limit exposure on historical worker's compensation claims. As of December 31, 2017 and 2016, $2.4 million and $0.0 million , respectively, are included in prepaid expenses and other current assets and $ 7.6 million and $14.2 million , respectively, are included in other non-current assets within the accompanying Consolidated Balance Sheets, which together represent the value of expected recoveries related to the underlying insured events. The related liabilities for the Company's worker's compensation exposure are included in other non-current liabilities within the accompanying Consolidated Balance Sheets.
Pension Obligations	Pension Obligations. The Company has a noncontributory, defined benefit pension plan covering current and former hourly employees at two of its active Sealy plants and ten previously closed Sealy U.S. facilities. Sealy Canada, Ltd. (a 100.0% owned subsidiary of the Company) also sponsors a noncontributory, defined benefit pension plan covering hourly employees at one of its facilities. Both plans provide retirement and survivorship benefits based on the employees' credited years of service. The Company's funding policy provides for contributions of an amount between the minimum required and maximum amount that can be deducted for federal income tax purposes. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at December 31, the measurement date. The benefit obligation is the projected benefit obligation (“PBO”). The PBO represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. The measurement of the PBO is based on the Company’s estimates and actuarial valuations. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions that require significant judgment, including estimates of discount rates, expected return on plan assets, rate of compensation increases, interest crediting rates and mortality rates.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2014-09, Revenue From Contracts With Customers (Topic 606), that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This ASU is based on the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The Company conducted a risk assessment and had developed a transition plan that enabled the Company to meet the implementation requirement. Revenue streams and performance obligations include product sales, sales-based royalties and warranties. The Company's contracts also include forms of variable consideration, including rebates (volume, cash and cooperative advertising), trade or other support, free products, slotting fees, and sales returns. Based on the evaluation of the Company's current contracts and the related revenue streams and performance obligations, most will be recorded consistently under both the current and new standard. The majority of the Company's revenue transactions are not accounted for under industry-specific guidance that will be superseded by Topic 606 and generally consist of a single performance obligation to transfer promised goods. The Company adopted the new revenue guidance effective January 1, 2018 using the modified retrospective method of adoption. The largest impacts as a result of the new standard are the new required qualitative and quantitative disclosures. Other presentation and disclosure changes include the reclassification of royalty income to revenue and changes in the balance sheet classification for sales returns. Under the new standard, the Company will continue to recognize the amount of consideration received or receivable that is expected to be returned as a refund liability, representing the Company's obligation to return the customer’s consideration. The Company evaluated the impact of the adoption on the classification of cooperative advertising programs and other promotional programs with the Company's customers. The impact of adoption to these promotional programs did not result in material changes in the Company's recognition or presentation of costs within the Company's Consolidated Statements of Income. As required under the new standard, the Company will establish a return asset for the right to recover the goods returned by the customer in 2018. The Company recognized a cumulative effect of initially applying the new standard as a decrease to the opening balance of retained earnings for approximately $3.0 million , net of tax. The Company does not expect the impact to cost of sales as a result of adjusting the return asset on an ongoing basis to be material. The return asset will be subject to impairment assessments on an ongoing basis. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases , that requires lessees to recognize most leases on the balance sheet and provides for expanded disclosures on key information about leasing arrangements. This ASU is effective for interim and annual periods beginning after December 5, 2018, which means it will become effective for the Company on January 1, 2019. In transition, the Company is required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating this ASU to determine the impact it will have on the Company's Consolidated Financial Statements. The Company expects that the adoption of the standard will result in a material increase to the assets and liabilities within the Consolidated Balance Sheets. Employee Share-Based Payments In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and the classification on the statement of cash flows. The Company adopted this ASU as of January 1, 2017. As a result of the adoption of this ASU: • The Company recognized all excess tax benefits and tax deficiencies as income tax provision or benefit in the Consolidated Statement of Income. The Company recognized excess tax deficiencies of $0.7 million for the year ended December 31, 2017. • The Company is prospectively presenting these excess tax benefits and tax deficiencies as an operating activity on the Consolidated Statement of Cash Flows. • The Company adopted a change in accounting policy to recognize forfeitures of awards as they occur instead of estimating potential forfeitures. Historically, the Company estimated the number of awards expected to be forfeited and adjusted the estimate when it was no longer probable that employees would fulfill their service conditions. The effect of this change in accounting policy is not material. Pensions In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which is accounting guidance that will change how employers who sponsor defined benefit pension and/or postretirement benefit plans present the net periodic benefit cost in the Consolidated Statements of Income. This guidance requires employers to present the service cost component of net periodic benefit cost in the same caption within the Consolidated Statements of Income as other employee compensation costs from services rendered during the period. All other components of the net periodic benefit cost will be presented separately outside of the operating income caption. This guidance must be applied retrospectively and will become effective for the Company on January 1, 2018. Adoption of this guidance will result in a reclassification of pension and other postretirement plan non-service income and re-measurement adjustments, net from within operating income to non-operating income.

Schedule of Stock Options Valuation Assumptions	The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock options granted. During the year ended December 31, 2016 , no stock options were granted. The assumptions used in the Black-Scholes option-pricing model for the years ended December 31, 2017 , 2016 and 2015 are set forth in the following table. Expected volatility is based on the unbiased standard deviation of Tempur Sealy International’s common stock over the option term. The expected life of the options represents the period of time that the Company expects the options granted to be outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant of the option for the expected term of the instrument. The dividend yield reflects an estimate of dividend payouts over the term of the award. During 2017, the Company adopted a change in accounting policy to recognize forfeitures of awards as they occur instead of estimating potential forfeitures. Historically, the Company estimated the number of awards expected to be forfeited and adjusted the estimate when it was no longer probable that employees would fulfill their service conditions.
