The accompanying unaudited condensed consolidated financial statements, taken as a whole, contain all adjustments that are of a normal recurring nature necessary to present fairly the financial position of the Company as of December 1, 2018 . Operating results for the three and six months ended December 1, 2018 , are not necessarily indicative of the results that may be expected for the year ending June 1, 2019 . It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company's annual report on Form 10-K for the year ended June 2, 2018

New Accounting Standards

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Standards	Recently Issued Accounting Standards Recently Adopted Accounting Standards Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Revenue from Contracts with Customers The standard 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. The core principle of the revenue model is 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. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The standard allows for two adoption methods, a full retrospective or modified retrospective approach. June 3, 2018 The Company adopted the standard effective June 3, 2018 using the modified retrospective method. Refer to Note 3 to the financial statements for further information regarding the adoption of the standard. Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities The standard provides guidance for the measurement, presentation and disclosure of financial assets and liabilities. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any change in fair value in net income. The standard does not permit early adoption and at adoption a cumulative-effect adjustment to beginning retained earnings should be recorded. June 3, 2018 The Company adopted the standard effective June 3, 2018 using the modified retrospective method. As a result, the Company reclassified $0.1 million of net gains on mutual fund equity securities, that were formerly classified as available for sale securities before the adoption of the new standard, from Accumulated other comprehensive loss to Retained earnings. The impact of adoption also resulted in certain disclosure changes. Refer to Note 11 of the financial statements for further information. Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Early adoption is permitted. September 2, 2018 The Company early adopted the standard prospectively effective September 2, 2018. The impacts resulting from adoption did not have an impact on the Company’s Financial Statements. Recently Adopted Accounting Standards (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This update allows for the reclassification to retained earnings of the tax effects stranded in Accumulated Other Comprehensive Income resulting from The Tax Cuts and Jobs Act. Early adoption is permitted. September 2, 2018 The Company early adopted the standard effective September 2, 2018 and reclassified $1.5 million from Accumulated other comprehensive loss to Retained earnings related to the Company’s interest rate swap agreements. Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost This standard changes the rules related to the income statement presentation of the components of net periodic benefit cost for defined benefit pension and other postretirement benefit plans. Under the new guidance, entities must present the service cost component of net periodic benefit cost in the same income statement line items as other employee compensation costs related to services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line items that include the service cost. Early adoption is permitted. June 3, 2018 The Company retrospectively adopted the standard effective June 3, 2018. Prior to adoption, the Company recorded net periodic benefit costs related to its defined benefit pension and post-retirement medical plans within Selling, general and administrative expenses. As a result of adoption, these costs are recorded within Other, net. The Company retrospectively reclassified these costs in the Condensed Consolidated Statements of Comprehensive Income for the period ending September 2, 2017 from Selling, general and administrative to Other, net. Refer to Note 7 of the financial statements for further information. Recently Issued Accounting Standards Not Yet Adopted Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities This update amends the hedge accounting recognition and presentation with the objectives of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and simplifying the application of hedge accounting. The update expands the strategies eligible for hedge accounting, relaxes the timing requirements of hedge documentation and effectiveness assessments and permits the use of qualitative assessments on an ongoing basis to assess hedge effectiveness. The new guidance also requires new disclosures and presentation. June 2, 2019 The Company is currently evaluating the impact of adopting this guidance. Leases Under the updated standard a lessee's rights and obligations under most leases, including existing and new arrangements, would be recognized as assets and liabilities, respectively, on the balance sheet. The standard must be adopted under a modified retrospective approach and early adoption is permitted. June 2, 2019 The standard is expected to have a significant impact on our Consolidated Financial Statements. The Company does not expect the Statement of Comprehensive Income to be significantly impacted. However, the impact to the balance sheet of recording right of use assets and lease liabilities for the Company’s operating leases, as well as the necessary financial statement disclosures, is expected to be significant. The Company has assembled a project team and is working towards implementation of the lease accounting standard. Measurement of Credit Losses on Financial Instruments This guidance replaces the existing incurred loss impairment model with an expected loss model and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. May 31, 2020 The Company is currently evaluating the impact of adopting this guidance. Recently Issued Accounting Standards Not Yet Adopted (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement This update eliminates, adds and modifies certain disclosure requirements for fair value measurements. Early adoption is permitted, and an entity is also permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their effective date. May 31, 2020 The Company is currently evaluating the impact of adopting this guidance. Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans This update eliminates, adds and clarifies certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Early adoption is permitted. May 30, 2021 The Company is currently evaluating the impact of adopting this guidance.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	Revenue from Contracts with Customers Impact of Adoption The Company adopted ASC 606 - Revenue from Contracts with Customers at the beginning of fiscal 2019. The Company completed its review of the impact of the new standard and identified certain key accounting policy changes that resulted from adopting the new standard. These included changes to the identification of performance obligations for commercial contracts in which the Company sells directly to end customers. Under previous accounting rules, which were codified under ASC 605, the Company generally delayed revenue recognition until the products were shipped and installed as the Company had concluded that contracts that contained both products and services represented a single, combined deliverable. However, under ASC 606, the Company has determined that products and services are distinct and as such, represent separate performance obligations. The Company also determined that under ASC 606, certain product pricing elements related to its direct customer sales should be recorded within Cost of sales rather than net within Net sales as had been historical practice under ASC 605. The Company adopted ASC 606 using the modified retrospective approach and applied the guidance therein to all applicable contracts that were not complete as of the date of adoption. As a result of these changes in accounting, the Company recorded a cumulative adjustment to retained earnings of $1.9 million on the date of adoption. With the change in performance obligations under ASC 606, product revenue recognition is accelerated on certain direct commercial customer sales. As a result, the cumulative adjustment recorded upon the adoption of ASC 606 had the impact of reducing inventory for sales transactions that would have been recognized in a prior period under ASC 606 and recording unbilled receivables for the amounts owed prior to invoicing. Additionally, the cumulative adjustment reflects the change in accrued expenses, including income taxes payable, related to these sales transactions. The cumulative impact to our Condensed Consolidated Balance Sheet as of June 3, 2018 was as follows: Balance at Adjustments due Balance at (In millions) June 2, 2018 to ASC 606 June 3, 2018 Balance Sheet Assets: Unbilled accounts receivable $ 1.9 $ 11.1 $ 13.0 Inventories, net 162.4 (7.1 ) 155.3 Liabilities: Accrued compensation and benefits 86.3 0.2 86.5 Other accrued liabilities 77.0 1.9 78.9 Equity: Retained earnings 598.3 1.9 600.2 In accordance with the modified retrospective adoption rules per ASC 606, the Company has disclosed in the tables below the differences in our financial statements due to the adoption of the standard. The “As reported” column represents the financial statement values recorded in accordance with ASC 606, while the “Legacy GAAP” column represents what the financial statement values would have been under ASC 605, had the new standard not been adopted.

Accounting Policies The Company recognizes revenue as performance obligations based on the terms of contracts with customers are satisfied. This happens when control of goods and services based on the contract have been conveyed to the customer. Revenue for the sale of products is typically recognized at the point in time when control transfers, generally upon transfer of title and risk of loss to the customer. Revenue for services, including the installation of products by the Company's owned dealers, is recognized over time as the services are provided. The method of revenue recognition may vary, depending on the type of contract with the customer, as noted in the section Disaggregated Revenue further below. The Company's contracts with customers include master agreements and certain other forms of contracts, which do not reach the level of a performance obligation until a purchase order is received from a customer. At the point in time that a purchase order under a contract is received by the Company, the collective group of documents represent an enforceable contract between the Company and the customer. While certain customer contracts may have a duration of greater than a year, all purchase orders are less than a year in duration. As of December 1, 2018 , all unfulfilled performance obligations are expected to be fulfilled in the next twelve months. Variable consideration exists within certain contracts that the Company has with customers. When variable consideration is present in a contract with a customer, the Company estimates the amount that should be included in the transaction price utilizing either the expected value method or the most likely amount method, depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Adjustments to Net sales from changes in variable consideration related to performance obligations completed in previous periods are not material to the Company's financial statements. Also, the Company has no contracts with significant financing components. The Company adopted the following accounting policies as a result of adopting the new standard on revenue recognition: – Shipping and Handling Activities - the Company accounts for shipping and handling activities as fulfillment activities and these costs are accrued within Cost of sales at the same time revenue is recognized. – Sales Taxes - the Company does not record revenue for sales tax, value added tax or other taxes that are collected on behalf of government entities. The Company’s revenue is recorded net of these taxes as they are passed through to the relevant government entities. – Incremental Costs of Obtaining a Contract - the Company has recognized incremental costs to obtain a contract as an expense when incurred as the amortization period is less than one year. – Significant Financing Component - the Company has not adjusted the amount of consideration to be received for any significant financing components as the Company’s contracts have a duration of one year or less. Disaggregated Revenue The Company’s revenue is comprised primarily of sales of products and installation services. Depending on the type of contract, the method of accounting and timing of revenue recognition may differ. Below, descriptions have been provided that summarize the Company’s different types of contracts and how revenue is recognized for each. – Single Performance Obligation - these contracts are transacted with customers and include only the product performance obligation. Most commonly, these contracts represent master agreements with independent third-party dealers in which a purchase order represents the customer contract, point of sale transactions through the Consumer reportable segment, as well as customer purchase orders for the Maharam subsidiary within the Specialty reportable segment. For contracts that include a single performance obligation, the Company records revenue at the point in time when title and risk of loss has transferred to the customer. – Multiple Performance Obligations - these contracts are transacted with customers and include more than one performance obligation; products, which are shipped to the customer by the Company and installation and other services, which are primarily fulfilled by independent third-party dealers. For contracts that include multiple performance obligations, the Company records revenue for the product performance obligation at the point in time when control transfers, generally upon transfer of title and risk of loss to the customer. In most cases, the Company has concluded that it is the agent for the installation services performance obligation and as such, the revenue and costs of these services are recorded net within “Net sales” in the Company’s Condensed Consolidated Statements of Comprehensive Income. In certain instances, entities owned by the Company, rather than independent third-party dealers, perform installation and other services. In these cases, Service revenue is generated by the Company’s entities that provide installation services, which include owned dealers, and is recognized by the Company over time as the services are provided. For c ontracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on relative standalone selling prices. – Other - these contracts are comprised mainly of alliance fee arrangements, whereby the Company earns revenue for allowing other furniture sellers access to its dealer distribution channel, as well as other miscellaneous selling arrangements. Revenue from alliance contracts are recorded at the point in time in which the sale is made by other furniture sellers through the Company’s sales channel. Revenue disaggregated by contract type has been provided in the table below: Three Months Ended Six Months Ended (In millions) December 1, 2018 December 1, 2018 Net Sales: Single performance obligation Product revenue $ 539.4 $ 1,074.6 Multiple performance obligations Product revenue 107.9 192.7 Service revenue 3.2 5.9 Other 2.1 4.1 Total $ 652.6 $ 1,277.3 Revenue disaggregated by product type and reportable segment has been provided in the table below: Three Months Ended Six Months Ended (In millions) December 1, 2018 December 1, 2018 North American Furniture Solutions: Systems $ 143.5 $ 288.1 Seating 100.0 196.6 Freestanding and storage 78.5 153.2 Other 31.2 59.0 Total North American Furniture Solutions $ 353.2 $ 696.9 ELA Furniture Solutions: Systems $ 28.4 $ 51.1 Seating 62.1 130.8 Freestanding and storage 13.9 24.3 Other 14.1 27.8 Total ELA Furniture Solutions $ 118.5 $ 234.0 Specialty: Systems $ 1.8 $ 3.3 Seating 26.9 55.9 Freestanding and storage 19.5 32.3 Textiles 4.0 9.0 Other 29.4 58.4 Total Specialty $ 81.6 $ 158.9 Consumer: Systems $ 0.1 $ 0.1 Seating 58.1 111.8 Freestanding and storage 16.8 34.0 Other 24.3 41.6 Total Consumer $ 99.3 $ 187.5 Total $ 652.6 $ 1,277.3 Refer to Note 16 of the Condensed Consolidated Financial Statements for further information related to our reportable segments. Contract Assets and Contract Liabilities The Company records contract assets and contract liabilities related to its revenue generating activities. Contract assets include certain receivables from customers that are unconditional as all performance obligations with respect to the contract with the customer have been completed. These amounts represent trade receivables and they are recorded within the caption “Accounts and notes receivable, net” in the Condensed Consolidated Balance Sheets. The payment terms for the Company's customers differs depending on the type of customer. For third party dealers and commercial contract customers, standard credit terms apply. Sales transacted through the Company's direct to consumer channels are generally paid for by the customer at point of sale. Contract assets also include amounts that are conditional because certain performance obligations in the contract with the customer are incomplete as of the balance sheet date. These contract assets generally arise due to contracts with the customer that include multiple performance obligations, both the product that is shipped to the customer by the Company, as well as installation services provided by independent third-party dealers. For these contracts, the Company recognizes revenue upon satisfaction of the product performance obligation. However, the asset is conditional and the customer is not invoiced by the Company until the installation performance obligation is completed. These contract assets are included in the caption "Unbilled accounts receivable" in the Condensed Consolidated Balance Sheets until all performance obligations in the contract with the customer have been satisfied. Contract liabilities represent deposits made by customers before the satisfaction of performance obligation(s) are complete and revenue is recognized. Upon completion of the performance obligation(s) that the Company has with the customer based on the terms of the contract, the liability for the customer deposit is relieved and revenue is recognized. These customer deposits are included within the caption “Customer deposits” in the Condensed Consolidated Balance Sheets. During the three and six month periods ended December 1, 2018 , the Company recognized Net sales of $17.8 million and $23.1 million , respectively, related to customer deposits there were included in the balance sheet as of September 1, 2018 and June 2, 2018

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recognizes interest and penalties related to uncertain tax benefits through income tax expense in its Condensed Consolidated Statement of Comprehensive Income. Interest and penalties recognized in the Company's Condensed Consolidated Statement of Comprehensive Income were negligible for the three and six months ended December 1, 2018 and December 2, 2017 . The Company's recorded liability for potential interest and penalties related to uncertain tax benefits was: (In millions) December 1, 2018 June 2, 2018 Liability for interest and penalties $ 0.9 $ 1.0 The components of the Company's unrecognized tax benefits are as follows: (In millions) Balance at June 2, 2018 $ 3.2 Increases related to current year income tax positions 0.2 Decreases related to settlements (1.1 ) Balance at December 1, 2018 $ 2.3 The balance of unrecognized tax benefits would impact the effective tax rate if recognized. On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was signed into law in the United States. The effects of the Act included the reduction of the federal corporate income tax rate from 35% to 21% and a new participation exemption system of taxation on foreign earnings, among other provisions. In accordance with SAB 118, for the three month period ended December 1, 2018 , the Company has not completed its accounting for all the effects of the Act, as the U.S. Treasury Department and the Internal Revenue Service continue to provide additional guidance. As a result of analyzing additional guidance, the Company has updated its provisional estimate related to foreign tax credits and recorded a discrete increase to income tax expense of $0.9 million . Additionally, the Company updated its provisional estimate for the one-time U.S. tax liability on certain undistributed foreign earnings and recorded a discrete decrease to income tax expense of $0.1 million . The Company will continue to refine its estimates as additional analysis is completed and further guidance is issued. Besides the one-time U.S. tax liability on undistributed foreign earnings as required by the Act, no other provision was made for income taxes that may result from future remittances of undistributed earnings of foreign subsidiaries that are determined to be indefinitely reinvested. Determination of the total amount of unrecognized deferred income tax on undistributed earnings of foreign subsidiaries is not practicable. For tax years beginning after December 31, 2017, the Act subjects a U.S. shareholder to tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred. The Company has not yet made its accounting policy election regarding GILTI deferred taxes. In determining the provision for income taxes for the three and six month periods ended December 1, 2018 , the Company used an estimated annual effective tax rate which was based on expected annual income and statutory tax rates across the various jurisdictions in which it operates, which included effects of the Act. The effective tax rates were 22.6% and 30.5% , respectively, for the three month period s ended December 1, 2018 and December 2, 2017 . The effective tax rates were 21.4% and 30.5% , respectively, for the six month period s ended December 1, 2018 and December 2, 2017 . The year over year decrease in the effective tax rate for the three and six months ended December 1, 2018 was the result of the Act. The effective tax rate for the three and six months ended December 1, 2018 is higher than the United States federal statutory rate due to the mix of earnings in taxing jurisdictions that had rates that were higher than the United States federal statutory rate. The effective tax rate for the three and six months ended December 2, 2017 is lower than the United States federal statutory rate due to the mix of earnings in taxing jurisdictions that had rates that were lower than the United States federal statutory rate, along with the research and development tax credit under the Protecting Americans from Tax Hikes ("PATH") Act of 2015. The Company is subject to periodic audits by domestic and foreign tax authorities. Currently, the Company is undergoing routine periodic audits in both domestic and foreign tax jurisdictions. It is reasonably possible that the amounts of unrecognized tax benefits could change in the next twelve months because of the audits. Tax payments related to these audits, if any, are not expected to be material to the Company's Condensed Consolidated Statements of Comprehensive Income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company's financial instruments consist of cash equivalents, marketable securities, accounts and notes receivable, deferred compensation plan, accounts payable, debt, redeemable noncontrolling interests, interest rate swaps and foreign currency exchange contracts. The Company's financial instruments, other than long-term debt, are recorded at fair value. The carrying value and fair value of the Company's long-term debt, including current maturities, is as follows for the periods indicated: (In millions) December 1, 2018 June 2, 2018 Carrying value $ 285.3 $ 285.8 Fair value $ 288.0 $ 288.6 The following describes the methods the Company uses to estimate the fair value of financial assets and liabilities, which have not significantly changed in the current period: Cash and cash equivalents — The Company invests excess cash in short term investments in the form of commercial paper and money market funds. Commercial paper is valued at amortized costs while money market funds are valued using net asset value. Equity securities — The Company's equity securities primarily include equity mutual funds. The equity mutual fund investments are recorded at fair value using quoted prices for similar securities. Available-for-sale securities — The Company's available-for-sale marketable securities primarily include fixed income mutual funds and government obligations. These investments are recorded at fair value using quoted prices for similar securities. Foreign currency exchange contracts — The Company's foreign currency exchange contracts are valued using an approach based on foreign currency exchange rates obtained from active markets. The estimated fair value of forward currency exchange contracts is based on month-end spot rates as adjusted by market-based current activity. These forward contracts are not designated as hedging instruments. Interest rate swap agreements — The value of the Company's interest rate swap agreements is determined using a market approach based on rates obtained from active markets. The interest rate swap agreements are designated as cash flow hedging instruments. Deferred compensation plan — The Company's deferred compensation plan primarily includes various domestic and international mutual funds that are recorded at fair value using quoted prices for similar securities. Other — The Company's contingent consideration liabilities and redeemable noncontrolling interests are deemed to be nonrecurring level 3 fair value measurement. Refer to Note 14 for further information regarding redeemable noncontrolling interests. The following table sets forth financial assets and liabilities measured at fair value through net income and the respective pricing levels to which the fair value measurements are classified within the fair value hierarchy as of December 1, 2018 and June 2, 2018 .

These payments are based on the future performance of the acquired businesses or product line. The contingent consideration liabilities are valued using estimates based on discount rates that reflect the risk involved and the projected sales and earnings of the acquired businesses. The estimates are updated and the liabilities are adjusted to fair value on a quarterly basis. The following is a summary of the carrying and market values of the Company's fixed income mutual funds and equity mutual funds as of the respective dates: December 1, 2018 June 2, 2018 (In millions) Cost Unrealized Gain/(loss) Market Value Cost Unrealized Market Mutual funds - fixed income $ 7.5 $ (0.1 ) $ 7.4 $ 7.8 $ (0.1 ) $ 7.7 Mutual funds - equity 0.7 0.1 0.8 0.7 0.2 0.9 Total $ 8.2 $ — $ 8.2 $ 8.5 $ 0.1 $ 8.6 Adjustments to the fair value of fixed income mutual funds are recorded as increases or decreases, net of income taxes, within Accumulated other comprehensive loss in stockholders’ equity. These adjustments are also included within the caption Unrealized holding gain within the Condensed Consolidated Statements of Comprehensive Income. Unrealized losses recognized in the Company's Condensed Consolidated Statement of Comprehensive Income related to fixed income mutual funds were zero and $0.1 million for the three and six month periods ended December 1, 2018 , respectively. Unrealized losses recognized in the Company's Condensed Consolidated Statement of Comprehensive Income related to fixed income mutual funds were zero for the three and six month periods ended December 2, 2017 . Adjustments to the fair value of equity mutual funds are recorded as increases or decreases, net of income taxes, in the Condensed Consolidated Statements of Comprehensive Income within Other, net. Unrealized gains recognized in the Company's Condensed Consolidated Statement of Comprehensive Income related to equity mutual funds were zero for the three and six month periods ended December 1, 2018 and December 2, 2017 . The cost of securities sold is based on the specific identification method; realized gains and losses resulting from such sales are included in the Condensed Consolidated Statements of Comprehensive Income within "Other, net". The Company reviews its investment portfolio for any unrealized losses that would be deemed other-than-temporary and require the recognition of an impairment loss in earnings. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, the duration and extent to which the fair value is less than its cost, the Company's intent to hold the investment, and whether it is more likely than not that the Company will be required to sell the investment before recovery of the cost basis. The Company also considers the type of security, related industry and sector performance, and published investment ratings. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis in the investment is established. If conditions within individual markets, industry segments, or macro-economic environments deteriorate, the Company could incur future impairments. The Company views its equity and fixed income mutual funds as available for use in its current operations. Accordingly, the investments are recorded within Current Assets within the Condensed Consolidated Balance Sheets. On June 3, 2018, as a result of the adoption of ASU 2016-01 - Financial Instruments , the Company reclassified net gains on mutual fund equity securities, that were formerly classified as available for sale securities before the adoption of the new standard, from Accumulated other comprehensive loss to Retained earnings. The impact of adoption was not material to the Company's financial statements. Derivative Instruments and Hedging Activities Foreign Currency Forward Contracts The Company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, the Company's strategy is to have increases or decreases in our foreign currency exposures offset by gains or losses on the foreign currency forward contracts to mitigate the risks and volatility associated with foreign currency transaction gains or losses. Foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. Foreign currency forward contracts generally settle within 30 days and are not used for trading purposes. These forward contracts are not designated as hedging instruments. Accordingly, we record the fair value of these contracts as of the end of the reporting period in the Consolidated Balance Sheets with changes in fair value recorded within the Consolidated Statements of Comprehensive Income. The balance sheet classification for the fair values of these forward contracts is to Other current assets for unrealized gains and to Other accrued liabilities for unrealized losses. The Consolidated Statements of Comprehensive Income classification for the fair values of these forward contracts is to Other expenses (income): Other, net, for both realized and unrealized gains and losses. The realized loss on foreign currency forward contracts was $0.2 million for the three months ended December 1, 2018 and December 2, 2017 , respectively. The realized gain on foreign currency forward contracts was $0.2 million for the six months ended December 1, 2018 and December 2, 2017 , respectively. Interest Rate Swaps The Company enters into interest rate swap agreements to manage its exposure to interest rate changes and its overall cost of borrowing. The Company's interest rate swap agreements were entered into to exchange variable rate interest payments for fixed rate payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amount of the interest rate swap agreements is used to measure interest to be paid or received and does not represent the amount of exposure to credit loss. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense. The interest rate swaps were designated cash flow hedges at inception and remain an effective accounting hedge as of December 1, 2018 . Since a designated derivative meets hedge accounting criteria, the fair value of the hedge is recorded in the Consolidated Statement of Stockholders’ Equity as a component of Accumulated other comprehensive loss, net of tax. The ineffective portion of the change in fair value of the derivatives is immediately recognized in earnings. The interest rate swap agreements are assessed for hedge effectiveness on a quarterly basis. In September 2016, the Company entered into an interest rate swap agreement. The interest rate swap is for an aggregate notional amount of $150.0 million with a forward start date of January 3, 2018 and a termination date of January 3, 2028. As a result of the transaction, the Company effectively converted indebtedness anticipated to be borrowed on the Company’s revolving line of credit up to the notional amount from a LIBOR-based floating interest rate plus applicable margin to a 1.949% fixed interest rate plus applicable margin under the agreement as of the forward start date. On June 12, 2017, the Company entered into an interest rate swap agreement. The interest rate swap is for an aggregate notional amount of $75.0 million with a forward start date of January 3, 2018 and a termination date of January 3, 2028. As a result of the transaction, the Company effectively converted the Company’s revolving line of credit up to the notional amount from a LIBOR-based floating interest rate plus applicable margin to a 2.387% fixed interest rate plus applicable margin under the agreement as of the forward start date. As of December 1, 2018 , the fair value of the Company’s two outstanding interest rate swap agreements, which are designated cash flow hedges, was an asset of $11.9 million . The asset fair value was recorded within Other noncurrent assets within the Condensed Consolidated Balance Sheets. The net unrealized gain recorded within Other comprehensive loss, net of tax, for the effective portion of the Company's designated cash flow hedges was $1.0 million and $2.6 million for the three months ended December 1, 2018 and December 2, 2017 , respectively. The net unrealized gain recorded within Other comprehensive loss, net of tax, for the effective portion of the Company's designated cash flow hedges was $0.5 million and $1.0 million for the six months ended December 1, 2018 and December 2, 2017 , respectively. There were no gains or losses recognized against earnings for hedge ineffectiveness for the three and six month periods ended December 1, 2018 and December 2, 2017 , respectively. The losses reclassified from Accumulated other comprehensive loss into earnings were $0.1 million and zero for three month periods ended December 1, 2018 and December 2, 2017 , respectively. There were no gains or losses reclassified from Accumulated other comprehensive loss into earnings for the six month periods ended December 1, 2018 and December 2, 2017 . The net of tax amount expected to be reclassified out of Accumulated other comprehensive loss into earnings during the next twelve months is a $0.9 million

Commitments and Contingencies Disclosure [Abstract]
Contingencies And Contingencies	Commitments and Contingencies Product Warranties The Company provides coverage to the end-user for parts and labor on products sold under its warranty policy and for other product-related matters. The standard length of warranty is 12 years for the majority of products sold; however, this varies depending on the product classification. The Company does not sell or otherwise issue warranties or warranty extensions as stand-alone products. Reserves have been established for the various costs associated with the Company's warranty program and are included in the Condensed Consolidated Balance Sheets under “Accrued warranty.” General warranty reserves are based on historical claims experience and other currently available information. These reserves are adjusted once an issue is identified and the actual cost of correction becomes known or can be estimated. The Company provides an assurance-type warranty that ensures that products will function as intended. As such, the Company's estimated warranty obligation is accounted for as a liability.

These arrangements are common in the industry and generally have terms ranging between one and three years. The bonds are required to provide assurance to customers that the products and services they have purchased will be installed and/or provided properly and without damage to their facilities. The bonds are provided by various bonding agencies. However, the Company is ultimately liable for claims that may occur against them. As of December 1, 2018 , the Company had a maximum financial exposure related to performance bonds totaling approximately $5.1 million . The Company has no history of claims, nor is it aware of circumstances that would require it to pay, under any of these arrangements. The Company also believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the Company's financial statements. Accordingly, no liability has been recorded in respect to these bonds as of either December 1, 2018 or June 2, 2018 . The Company has entered into standby letter of credit arrangements for purposes of protecting various insurance companies and lessors against default on insurance premium and lease payments. As of December 1, 2018 , the Company had a maximum financial exposure from these standby letters of credit totaling approximately $11.3 million , all of which is considered usage against the Company's revolving line of credit. The Company has no history of claims, nor is it aware of circumstances that would require it to perform under any of these arrangements, and believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the Company's financial statements. Accordingly, no liability has been recorded in respect of these arrangements as of December 1, 2018 and June 2, 2018 . Contingencies The Company is also involved in legal proceedings and litigation arising in the ordinary course of business. In the opinion of management, the outcome of such proceedings and litigation currently pending will not materially affect the Company's consolidated financial statements.

The facility will expire in September 2021 and outstanding borrowings bear interest at rates based on the prime rate, federal funds rate, LIBOR or negotiated rates as outlined in the agreement. Interest is payable periodically throughout the period if borrowings are outstanding. As of December 1, 2018 , the total debt outstanding related to borrowings under the syndicated revolving line of credit was $225.0 million . Available borrowings against this facility were $163.7 million due to $11.3 million related to outstanding letters of credit. As of June 2, 2018, total debt outstanding related to borrowings under the syndicated revolving line of credit was $225.0 million and available borrowings were $166.8 million due to $8.2 million outstanding letters of credit. Supplier Financing Program The Company has an agreement wit h a third party financial institution to provide a platform that allows certain participating suppliers the ability to finance payment obligations from the Company. Under this program, participating suppliers may finance payment obligations of the Company, prior to their scheduled due dates, at a discounted price to the third party financial institution. The Company has lengthened the payment terms for certain suppliers that have chosen to participate in the program. As a result, certain amounts due to suppliers have payment terms that are longer than standard industry practice and as such, these amounts have been excluded from the caption “Accounts payable” in the Condensed Consolidated Balance Sheets as the amounts have been accounted for by the Company as a current debt obligation. Accordingly, $3.4 million and $3.8 million have been recorded within the caption “Other accrued liabilities” for the periods ended December 1, 2018 and June 2, 2018 , respectively. Construction-Type Lease During fiscal 2015, the Company entered into a lease agreement for the occupancy of a new studio facility in Palo Alto, California which runs through fiscal 2026. In fiscal 2017, the Company became the deemed owner of the leased building for accounting purposes as a result of the Company's involvement during the construction phase of the project. The lease is therefore accounted for as a financing transaction and the building and related financing liability were initially recorded at fair value in the Consolidated Balance Sheets within both Construction in progress and Other accrued liabilities. The fair value of the building and financing liability was determined through a blend of an income approach, comparable property sales approach and a replacement cost approach. During the first quarter of fiscal 2018, the construction was substantially completed, and the property was placed in service. As a result, the Company began depreciating the assets over their estimated useful lives. The Company also reclassified the related financing liability to Long-term debt. Additionally, the Company began allocating its monthly lease payments between land rent, which is recorded as an operating lease expense, interest expense and the reduction of the related lease obligation. The imputed interest rate on the financing liability is 2.9% , our incremental borrowing rate. The carrying value of the building and the related financing liability were both $6.9 million at December 1, 2018 . The carrying value of the building and the related financing liability were both $7.0 million at June 2, 2018

Restructuring and Related Activities Disclosure [Text Block]	Restructuring and Impairment Expenses Fiscal 2019 Restructuring Expenses ELA segment During the fourth quarter of fiscal 2018, the Company announced a facilities consolidation plan related to its ELA segment. This impacted certain office and manufacturing facilities in the United Kingdom and China. It is currently contemplated that this plan will generate approximately $3 million in annual cost reductions as part of the Company's three-year cost savings initiatives. In the second quarter of fiscal 2019, the Company recognized restructuring expenses of $0.3 million related to the consolidation of certain facilities in China and the United Kingdom that were announced in the fourth quarter of fiscal 2018.

As the United Kingdom office building and related assets meet the criteria to be designated as assets held for sale, the carrying value of these assets have been classified as current assets and included within "Prepaid expenses and other" in the Condensed Consolidated Balance Sheets for the period ended December 1, 2018 . The carrying amount of the assets held for sale was approximately $5.0 million as of December 1, 2018 .

Revenue from Contracts with Customers [Abstract]
New Accounting Pronouncements, Policy	Recently Adopted Accounting Standards Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Revenue from Contracts with Customers The standard 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. The core principle of the revenue model is 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. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The standard allows for two adoption methods, a full retrospective or modified retrospective approach. June 3, 2018 The Company adopted the standard effective June 3, 2018 using the modified retrospective method. Refer to Note 3 to the financial statements for further information regarding the adoption of the standard. Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities The standard provides guidance for the measurement, presentation and disclosure of financial assets and liabilities. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any change in fair value in net income. The standard does not permit early adoption and at adoption a cumulative-effect adjustment to beginning retained earnings should be recorded. June 3, 2018 The Company adopted the standard effective June 3, 2018 using the modified retrospective method. As a result, the Company reclassified $0.1 million of net gains on mutual fund equity securities, that were formerly classified as available for sale securities before the adoption of the new standard, from Accumulated other comprehensive loss to Retained earnings. The impact of adoption also resulted in certain disclosure changes. Refer to Note 11 of the financial statements for further information. Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Early adoption is permitted. September 2, 2018 The Company early adopted the standard prospectively effective September 2, 2018. The impacts resulting from adoption did not have an impact on the Company’s Financial Statements. Recently Adopted Accounting Standards (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This update allows for the reclassification to retained earnings of the tax effects stranded in Accumulated Other Comprehensive Income resulting from The Tax Cuts and Jobs Act. Early adoption is permitted. September 2, 2018 The Company early adopted the standard effective September 2, 2018 and reclassified $1.5 million from Accumulated other comprehensive loss to Retained earnings related to the Company’s interest rate swap agreements. Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost This standard changes the rules related to the income statement presentation of the components of net periodic benefit cost for defined benefit pension and other postretirement benefit plans. Under the new guidance, entities must present the service cost component of net periodic benefit cost in the same income statement line items as other employee compensation costs related to services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line items that include the service cost. Early adoption is permitted. June 3, 2018 The Company retrospectively adopted the standard effective June 3, 2018. Prior to adoption, the Company recorded net periodic benefit costs related to its defined benefit pension and post-retirement medical plans within Selling, general and administrative expenses. As a result of adoption, these costs are recorded within Other, net. The Company retrospectively reclassified these costs in the Condensed Consolidated Statements of Comprehensive Income for the period ending September 2, 2017 from Selling, general and administrative to Other, net. Refer to Note 7 of the financial statements for further information. Recently Issued Accounting Standards Not Yet Adopted Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities This update amends the hedge accounting recognition and presentation with the objectives of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and simplifying the application of hedge accounting. The update expands the strategies eligible for hedge accounting, relaxes the timing requirements of hedge documentation and effectiveness assessments and permits the use of qualitative assessments on an ongoing basis to assess hedge effectiveness. The new guidance also requires new disclosures and presentation. June 2, 2019 The Company is currently evaluating the impact of adopting this guidance. Leases Under the updated standard a lessee's rights and obligations under most leases, including existing and new arrangements, would be recognized as assets and liabilities, respectively, on the balance sheet. The standard must be adopted under a modified retrospective approach and early adoption is permitted. June 2, 2019 The standard is expected to have a significant impact on our Consolidated Financial Statements. The Company does not expect the Statement of Comprehensive Income to be significantly impacted. However, the impact to the balance sheet of recording right of use assets and lease liabilities for the Company’s operating leases, as well as the necessary financial statement disclosures, is expected to be significant. The Company has assembled a project team and is working towards implementation of the lease accounting standard. Measurement of Credit Losses on Financial Instruments This guidance replaces the existing incurred loss impairment model with an expected loss model and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. May 31, 2020 The Company is currently evaluating the impact of adopting this guidance. Recently Issued Accounting Standards Not Yet Adopted (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement This update eliminates, adds and modifies certain disclosure requirements for fair value measurements. Early adoption is permitted, and an entity is also permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their effective date. May 31, 2020 The Company is currently evaluating the impact of adopting this guidance. Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans This update eliminates, adds and clarifies certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Early adoption is permitted. May 30, 2021 The Company is currently evaluating the impact of adopting this guidance. ASU 2017-07 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost on June 3, 2018. As the Company's pension and post retirement medical plans are frozen and not open to new plan participants, these plans no longer have a service component in net periodic benefit cost. Prior to adoption, the Company recorded net periodic benefit costs related to its defined benefit pension and post-retirement medical plans within Selling, general and administrative expenses. As a result of adoption, these costs are recorded within Other, net. The Company retrospectively reclassified $0.4 million and $0.8 million

Revenue from Contracts with Customers [Abstract]
Revenue from Contract with Customer Policy	Significant Financing Component - the Company has not adjusted the amount of consideration to be received for any significant financing components as the Company’s contracts have a duration of one year or less.The Company recognizes revenue as performance obligations based on the terms of contracts with customers are satisfied. This happens when control of goods and services based on the contract have been conveyed to the customer. Revenue for the sale of products is typically recognized at the point in time when control transfers, generally upon transfer of title and risk of loss to the customer. Revenue for services, including the installation of products by the Company's owned dealers, is recognized over time as the services are provided. The method of revenue recognition may vary, depending on the type of contract with the customer, as noted in the section Disaggregated Revenue further below. The Company's contracts with customers include master agreements and certain other forms of contracts, which do not reach the level of a performance obligation until a purchase order is received from a customer. At the point in time that a purchase order under a contract is received by the Company, the collective group of documents represent an enforceable contract between the Company and the customer. While certain customer contracts may have a duration of greater than a year, all purchase orders are less than a year in duration. As of December 1, 2018 , all unfulfilled performance obligations are expected to be fulfilled in the next twelve months.
Shipping and Handling Activities Policy	Shipping and Handling Activities - the Company accounts for shipping and handling activities as fulfillment activities and these costs are accrued within Cost of sales at the same time revenue is recognized.
Sales Tax Policy	Sales Taxes -
Incremental Costs of Obtaining a Contract Policy	Incremental Costs of Obtaining a Contract - the Company has recognized incremental costs to obtain a contract as an expense when incurred as the amortization period is less than one year.
Single Performance Obligation Revenue Policy	Single Performance Obligation - these contracts are transacted with customers and include only the product performance obligation. Most commonly, these contracts represent master agreements with independent third-party dealers in which a purchase order represents the customer contract, point of sale transactions through the Consumer reportable segment, as well as customer purchase orders for the Maharam subsidiary within the Specialty reportable segment. For contracts that include a single performance obligation, the Company records revenue at the point in time when title and risk of loss has transferred to the customer.
Multiple Performance Obligations Revenue Policy	– Multiple Performance Obligations - these contracts are transacted with customers and include more than one performance obligation; products, which are shipped to the customer by the Company and installation and other services, which are primarily fulfilled by independent third-party dealers. For contracts that include multiple performance obligations, the Company records revenue for the product performance obligation at the point in time when control transfers, generally upon transfer of title and risk of loss to the customer. In most cases, the Company has concluded that it is the agent for the installation services performance obligation and as such, the revenue and costs of these services are recorded net within “Net sales” in the Company’s Condensed Consolidated Statements of Comprehensive Income. In certain instances, entities owned by the Company, rather than independent third-party dealers, perform installation and other services. In these cases, Service revenue is generated by the Company’s entities that provide installation services, which include owned dealers, and is recognized by the Company over time as the services are provided. For c
Other Revenue Policy	Other - these contracts are comprised mainly of alliance fee arrangements, whereby the Company earns revenue for allowing other furniture sellers access to its dealer distribution channel, as well as other miscellaneous selling arrangements. Revenue from alliance contracts are recorded at the point in time in which the sale is made by other furniture sellers through the Company’s sales channel.

The core principle of the revenue model is 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. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The standard allows for two adoption methods, a full retrospective or modified retrospective approach. June 3, 2018 The Company adopted the standard effective June 3, 2018 using the modified retrospective method. Refer to Note 3 to the financial statements for further information regarding the adoption of the standard. Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities The standard provides guidance for the measurement, presentation and disclosure of financial assets and liabilities. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any change in fair value in net income. The standard does not permit early adoption and at adoption a cumulative-effect adjustment to beginning retained earnings should be recorded. June 3, 2018 The Company adopted the standard effective June 3, 2018 using the modified retrospective method. As a result, the Company reclassified $0.1 million of net gains on mutual fund equity securities, that were formerly classified as available for sale securities before the adoption of the new standard, from Accumulated other comprehensive loss to Retained earnings. The impact of adoption also resulted in certain disclosure changes. Refer to Note 11 of the financial statements for further information. Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Early adoption is permitted. September 2, 2018 The Company early adopted the standard prospectively effective September 2, 2018. The impacts resulting from adoption did not have an impact on the Company’s Financial Statements. Recently Adopted Accounting Standards (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This update allows for the reclassification to retained earnings of the tax effects stranded in Accumulated Other Comprehensive Income resulting from The Tax Cuts and Jobs Act. Early adoption is permitted. September 2, 2018 The Company early adopted the standard effective September 2, 2018 and reclassified $1.5 million from Accumulated other comprehensive loss to Retained earnings related to the Company’s interest rate swap agreements. Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost This standard changes the rules related to the income statement presentation of the components of net periodic benefit cost for defined benefit pension and other postretirement benefit plans. Under the new guidance, entities must present the service cost component of net periodic benefit cost in the same income statement line items as other employee compensation costs related to services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line items that include the service cost. Early adoption is permitted. June 3, 2018 The Company retrospectively adopted the standard effective June 3, 2018. Prior to adoption, the Company recorded net periodic benefit costs related to its defined benefit pension and post-retirement medical plans within Selling, general and administrative expenses. As a result of adoption, these costs are recorded within Other, net. The Company retrospectively reclassified these costs in the Condensed Consolidated Statements of Comprehensive Income for the period ending September 2, 2017 from Selling, general and administrative to Other, net. Refer to Note 7 of the financial statements for further information. Recently Issued Accounting Standards Not Yet Adopted Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities This update amends the hedge accounting recognition and presentation with the objectives of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and simplifying the application of hedge accounting. The update expands the strategies eligible for hedge accounting, relaxes the timing requirements of hedge documentation and effectiveness assessments and permits the use of qualitative assessments on an ongoing basis to assess hedge effectiveness. The new guidance also requires new disclosures and presentation. June 2, 2019 The Company is currently evaluating the impact of adopting this guidance. Leases Under the updated standard a lessee's rights and obligations under most leases, including existing and new arrangements, would be recognized as assets and liabilities, respectively, on the balance sheet. The standard must be adopted under a modified retrospective approach and early adoption is permitted. June 2, 2019 The standard is expected to have a significant impact on our Consolidated Financial Statements. The Company does not expect the Statement of Comprehensive Income to be significantly impacted. However, the impact to the balance sheet of recording right of use assets and lease liabilities for the Company’s operating leases, as well as the necessary financial statement disclosures, is expected to be significant. The Company has assembled a project team and is working towards implementation of the lease accounting standard. Measurement of Credit Losses on Financial Instruments This guidance replaces the existing incurred loss impairment model with an expected loss model and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. May 31, 2020 The Company is currently evaluating the impact of adopting this guidance. Recently Issued Accounting Standards Not Yet Adopted (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement This update eliminates, adds and modifies certain disclosure requirements for fair value measurements. Early adoption is permitted, and an entity is also permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their effective date. May 31, 2020 The Company is currently evaluating the impact of adopting this guidance. Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans This update eliminates, adds and clarifies certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Early adoption is permitted. May 30, 2021 The Company is currently evaluating the impact of adopting this guidance. ASU 2017-07 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost on June 3, 2018. As the Company's pension and post retirement medical plans are frozen and not open to new plan participants, these plans no longer have a service component in net periodic benefit cost. Prior to adoption, the Company recorded net periodic benefit costs related to its defined benefit pension and post-retirement medical plans within Selling, general and administrative expenses. As a result of adoption, these costs are recorded within Other, net. The Company retrospectively reclassified $0.4 million and $0.8 million

Fair Value Measurements (Polici

Fair Value Measurements (Policies)	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments, Policy	Adjustments to the fair value of fixed income mutual funds are recorded as increases or decreases, net of income taxes, within Accumulated other comprehensive loss in stockholders’ equity. These adjustments are also included within the caption Unrealized holding gain within the Condensed Consolidated Statements of Comprehensive Income. Unrealized losses recognized in the Company's Condensed Consolidated Statement of Comprehensive Income related to fixed income mutual funds were zero and $0.1 million for the three and six month periods ended December 1, 2018 , respectively. Unrealized losses recognized in the Company's Condensed Consolidated Statement of Comprehensive Income related to fixed income mutual funds were zero for the three and six month periods ended December 2, 2017 . Adjustments to the fair value of equity mutual funds are recorded as increases or decreases, net of income taxes, in the Condensed Consolidated Statements of Comprehensive Income within Other, net. Unrealized gains recognized in the Company's Condensed Consolidated Statement of Comprehensive Income related to equity mutual funds were zero for the three and six month periods ended December 1, 2018 and December 2, 2017 .
Marketable Securities, Policy [Policy Text Block]	The Company reviews its investment portfolio for any unrealized losses that would be deemed other-than-temporary and require the recognition of an impairment loss in earnings. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, the duration and extent to which the fair value is less than its cost, the Company's intent to hold the investment, and whether it is more likely than not that the Company will be required to sell the investment before recovery of the cost basis. The Company also considers the type of security, related industry and sector performance, and published investment ratings. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis in the investment is established. If conditions within individual markets, industry segments, or macro-economic environments deteriorate, the Company could incur future impairments. The Company views its equity and fixed income mutual funds as available for use in its current operations. Accordingly, the investments are recorded within Current Assets within the Condensed Consolidated Balance Sheets.
Derivatives, Methods of Accounting, Hedging Derivatives [Policy Text Block]	Foreign Currency Forward Contracts The Company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, the Company's strategy is to have increases or decreases in our foreign currency exposures offset by gains or losses on the foreign currency forward contracts to mitigate the risks and volatility associated with foreign currency transaction gains or losses. Foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. Foreign currency forward contracts generally settle within 30 days and are not used for trading purposes. These forward contracts are not designated as hedging instruments. Accordingly, we record the fair value of these contracts as of the end of the reporting period in the Consolidated Balance Sheets with changes in fair value recorded within the Consolidated Statements of Comprehensive Income. The balance sheet classification for the fair values of these forward contracts is to Other current assets for unrealized gains and to Other accrued liabilities for unrealized losses. The Consolidated Statements of Comprehensive Income classification for the fair values of these forward contracts is to Other expenses (income): Other, net, for both realized and unrealized gains and losses. The realized loss on foreign currency forward contracts was $0.2 million for the three months ended December 1, 2018 and December 2, 2017 , respectively. The realized gain on foreign currency forward contracts was $0.2 million for the six months ended December 1, 2018 and December 2, 2017 , respectively. Interest Rate Swaps The Company enters into interest rate swap agreements to manage its exposure to interest rate changes and its overall cost of borrowing. The Company's interest rate swap agreements were entered into to exchange variable rate interest payments for fixed rate payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amount of the interest rate swap agreements is used to measure interest to be paid or received and does not represent the amount of exposure to credit loss. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense. The interest rate swaps were designated cash flow hedges at inception and remain an effective accounting hedge as of December 1, 2018 . Since a designated derivative meets hedge accounting criteria, the fair value of the hedge is recorded in the Consolidated Statement of Stockholders’ Equity as a component of Accumulated other comprehensive loss, net of tax. The ineffective portion of the change in fair value of the derivatives is immediately recognized in earnings. The interest rate swap agreements are assessed for hedge effectiveness on a quarterly basis.
