Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fiscal Period, Policy [Policy Text Block]	Fiscal Periods Our fiscal year ends on the Saturday nearest to January 31, which results in fiscal years consisting of 52 or 53 weeks. Unless otherwise stated, references to years in this report relate to fiscal years rather than calendar years. Fiscal year 2015 (“2015”) is comprised of the 52 weeks that began on February 1, 2015 and will end on January 30, 2016. Fiscal year 2014 (“2014”) was comprised of the 52 weeks that began on February 2, 2014 and ended on January 31, 2015. The fiscal quarters ended October 31, 2015 (“third quarter of 2015”) and November 1, 2014 (“third quarter of 2014”) were both comprised of 13 weeks. The year-to-date periods ended October 31, 2015 (“year-to-date 2015”) and November 1, 2014 (“year-to-date 2014”) were both comprised of 39 weeks.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Selling and Administrative Expenses Selling and administrative expenses include store expenses (such as payroll and occupancy costs) and costs related to warehousing, distribution, outbound transportation to our stores, advertising, purchasing, insurance, non-income taxes, and overhead. Our selling and administrative expense rates may not be comparable to those of other retailers that include distribution and outbound transportation costs in cost of sales. Distribution and outbound transportation costs included in selling and administrative expenses were $41.0 million and $40.9 million for the third quarter of 2015 and the third quarter of 2014, respectively, and $120.3 million and $119.0 million for the year-to-date 2015 and the year-to-date 2014, respectively.
Advertising Costs, Policy [Policy Text Block]	Advertising Expense Advertising costs, which are expensed as incurred, consist primarily of television and print advertising, digital or internet marketing and advertising, and in-store point-of-purchase presentations. Advertising expenses are included in selling and administrative expenses. Advertising expenses were $15.9 million and $16.9 million for the third quarter of 2015 and the third quarter of 2014, respectively, and $53.7 million and $57.7 million for the year-to-date 2015 and the year-to-date 2014, respectively.
Derivatives, Policy [Policy Text Block]	Derivative Instruments We use derivative instruments to mitigate the risk of market fluctuations in diesel fuel prices. We do not enter into derivative instruments for speculative purposes. Our derivative instruments may consist of collar or swap contracts. Our current derivative instruments do not meet the requirements for cash flow hedge accounting. Instead, our derivative instruments are marked-to-market to determine their fair value and any gains or losses are recognized currently in other income (expense) on our consolidated statements of operations.
Reclassification, Policy [Policy Text Block]	Reclassifications Merchandise Categories In the first quarter of 2015, we realigned select merchandise categories to be consistent with the realignment of our merchandising team and changes to our management reporting. Specifically, we reclassified our home décor and frames departments from our former Furniture & Home Décor category to our Soft Home category. Subsequently, we changed the name of our Furniture & Home Décor category to Furniture. In order to provide comparative information, we have reclassified our net sales by merchandise category into this revised alignment for all periods presented in note 9 to the consolidated financial statements. We periodically assess, and make minor adjustments to, our product hierarchy, which can impact the roll-up of our merchandise categories. Our financial reporting process utilizes the most current product hierarchy in reporting net sales by merchandise category for all periods presented. Therefore, there may be minor reclassifications of net sales by merchandise category compared to previously reported amounts.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). This update provides 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. Additionally, this guidance expands related disclosure requirements. The pronouncement was originally set to be effective for annual and interim reporting periods beginning after December 15, 2016. In July 2015, the FASB approved a one-year deferral of the effective date from December 15, 2016 to December 15, 2017, but will allow for early adoption as of December 15, 2016. This ASU permits the use of either the retrospective or cumulative effect transition method. We are currently evaluating the impact this guidance will have on our consolidated financial statements as well as the expected adoption method. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. This update requires an entity to classify deferred tax liabilities and assets as noncurrent within a classified statement of financial position. ASU 2015-17 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2016. This update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early application is permitted as of the beginning of an interim or annual reporting period. We do not expect that the adoption of this guidance will have a significant impact on our consolidated financial statements.
