Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
	We prepared the condensed consolidated financial statements as of and for the three months ended April 4, 2015 of Select Comfort Corporation and 100%-owned subsidiaries (“Select Comfort” or the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and they reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly our financial position as of April 4, 2015, and January 3, 2015, and the consolidated results of operations and cash flows for the periods presented. Our historical and quarterly consolidated results of operations may not be indicative of the results that may be achieved for the full year or any future period.
	Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with our most recent audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended January 3, 2015 and other recent filings with the SEC.
	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of sales, expenses and income taxes during the reporting period. Predicting future events is inherently an imprecise activity and, as such, requires the use of judgment. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods. Our critical accounting policies consist of stock-based compensation, goodwill and indefinite-lived intangible assets, warranty liabilities and revenue recognition.
	The condensed consolidated financial statements include the accounts of Select Comfort Corporation and our 100%-owned subsidiaries. All significant intra-entity balances and transactions have been eliminated in consolidation.
	New Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) issued a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This new guidance was originally effective for annual reporting periods beginning after December 15, 2016 and early adoption was not permitted. On April 1, 2015, the FASB voted in favor of proposing a one-year delay of the effective date and to permit companies to voluntarily adopt the new standard as of the original effective date. Early adoption prior to the original effective date is not permitted. A final decision on the effective date is expected in 2015. Companies may use either a full retrospective or a modified retrospective approach to adopt this new guidance. We are evaluating the effect of the new standard on our consolidated financial statements and related disclosures, and have not yet selected a transition method.

	At April 4, 2015 and January 3, 2015, we had $1.2 million and $1.0 million, respectively, of debt and equity securities that fund our deferred compensation plan and are classified in other assets in our condensed consolidated balance sheets. We also had corresponding deferred compensation plan liabilities of $1.2 million and $1.0 million at April 4, 2015 and January 3, 2015, respectively, which are included in other long-term liabilities in our condensed consolidated balance sheets. The majority of the debt and equity securities are Level 1 as they trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. Unrealized gains/(losses) on the debt and equity securities offset those associated with the corresponding deferred compensation plan liabilities.

Debt	Credit Agreement
	Our $20.0 million Credit Agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association, as amended, is an unsecured revolving credit facility that matures on August 31, 2016. The Credit Agreement contains an accordion feature that allows us to increase the amount of the line from $20 million to up to $50 million in total availability, subject to lender approval.
	Any borrowings under the Credit Agreement will, at our request, be classified as either LIBOR Loans or Adjusted Base Rate (“ABR”) Loans (both as defined in the Credit Agreement). The rate of interest payable by us in respect of loans outstanding under the revolving credit facility is: (i) with respect to LIBOR Loans, the Adjusted LIBO Rate (as defined in the Credit Agreement) for the interest period then in effect, plus 1.25%; or (ii) with respect to ABR Loans, the ABR (as defined in the Credit Agreement) then in effect for the Daily One-Month LIBO Rate (as defined in the Credit Agreement), plus 1.50% or the prime rate. We are subject to certain financial covenants under the Credit Agreement, including minimum tangible net worth, a requirement to maintain a minimum amount of cash, cash equivalents and marketable debt securities, and to maintain at the administrative agent cash, cash equivalents and marketable debt securities equal to the amount the lenders are committed to lend under the Credit Agreement.
	At both April 4, 2015 and January 3, 2015, we had no borrowings and $20 million was available under the Credit Agreement. We had no outstanding letters of credit as of April 4, 2015 or January 3, 2015.

	Legal Proceedings
	We are involved from time to time in various legal proceedings arising in the ordinary course of our business, including primarily commercial, product liability, employment and intellectual property claims. In accordance with generally accepted accounting principles in the United States, we record a liability in our consolidated financial statements with respect to any of these matters when it is both probable that a liability has been incurred and the amount of the liability can be reasonably estimated. With respect to currently pending legal proceedings, we have not established an estimated range of reasonably possible additional losses either because we believe that we have valid defenses to claims asserted against us or the proceeding has not advanced to a stage of discovery that would enable us to establish an estimate. We currently do not expect the outcome of these matters to have a material effect on our consolidated results of operations, financial position or cash flows. Litigation, however, is inherently unpredictable, and it is possible that the ultimate outcome of one or more claims asserted against us could adversely impact our consolidated results of operations, financial position or cash flows. We expense legal costs as incurred.
	On August 23, 2013, we filed a complaint in U.S. District Court in the District of Minnesota against Gentherm, Inc. seeking a declaratory judgment that Select Comfort be named as an assignee of certain patents asserted against Select Comfort by Gentherm or in the alternative that the asserted patents are not enforceable or are invalid or that Select Comfort and its products do not infringe any valid claim of the asserted patents. This complaint was filed after Gentherm asserted in a letter that Select Comfort’s recently introduced DualTemp™ layer product infringed certain patents owned by Gentherm. Subsequently, Gentherm filed counterclaims alleging infringement of its patents and seeking various legal and equitable remedies, including injunctive relief, treble damages and attorney’s fees. In March of 2015, the parties agreed to dismiss without prejudice all of the claims and counterclaims asserted in this litigation.

Accounting Policies [Abstract]
Business and Basis of Presentation, Policy	We prepared the condensed consolidated financial statements as of and for the three months ended April 4, 2015 of Select Comfort Corporation and 100%-owned subsidiaries (“Select Comfort” or the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and they reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly our financial position as of April 4, 2015, and January 3, 2015, and the consolidated results of operations and cash flows for the periods presented. Our historical and quarterly consolidated results of operations may not be indicative of the results that may be achieved for the full year or any future period.
	Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with our most recent audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended January 3, 2015 and other recent filings with the SEC.
Use of Estimates, Policy	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of sales, expenses and income taxes during the reporting period. Predicting future events is inherently an imprecise activity and, as such, requires the use of judgment. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods. Our critical accounting policies consist of stock-based compensation, goodwill and indefinite-lived intangible assets, warranty liabilities and revenue recognition.
Consolidation, Policy	The condensed consolidated financial statements include the accounts of Select Comfort Corporation and our 100%-owned subsidiaries. All significant intra-entity balances and transactions have been eliminated in consolidation.
New Accounting Pronouncements, Policy	In May 2014, the Financial Accounting Standards Board (FASB) issued a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This new guidance was originally effective for annual reporting periods beginning after December 15, 2016 and early adoption was not permitted. On April 1, 2015, the FASB voted in favor of proposing a one-year delay of the effective date and to permit companies to voluntarily adopt the new standard as of the original effective date. Early adoption prior to the original effective date is not permitted. A final decision on the effective date is expected in 2015. Companies may use either a full retrospective or a modified retrospective approach to adopt this new guidance. We are evaluating the effect of the new standard on our consolidated financial statements and related disclosures, and have not yet selected a transition method.
Stockholders' Equity, Policy	There is no expiration date governing the period over which we can repurchase shares. Any repurchased shares are constructively retired and returned to an unissued status. The cost of stock repurchases is first charged to additional paid-in-capital. Once additional paid-in capital is reduced to zero, any additional amounts are charged to retained earnings.
