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.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
