Stockholders' Equity Note [Abstract]
Stockholders' Equity	15. Stockholders’ Equity Prior to the Business Combination, GPAC was a shell company with no operations, formed as a vehicle to effect a business combination with one or more operating businesses. After the Closing, the Company became a holding company whose sole material asset consists of its interest in Purple LLC. *Class A Common Stock* The Company has 210.0 million shares of Class A Stock authorized at a par value of $0.0001 per share. Holders of the Company’s Class A Stock are entitled to one vote for each share held on all matters to be voted on by the stockholders and participate in dividends, if declared by the Board, or receive any portion of any such assets in respect of their shares upon liquidation, dissolution, distribution of assets or winding-up of the Company in excess of the par value of such stock. Holders of the Class A Stock and holders of the Class B Stock voting together as a single class, have the exclusive right to vote for the election of directors and on all other matters properly submitted to a vote of the stockholders. Holders of Class A Stock and Class B Stock are entitled to one vote per share on matters to be voted on by stockholders. At December 31, 2020, 63.9 million shares of Class A Stock were outstanding. In connection with the Business Combination, all of GPAC’s issued and outstanding shares of common stock were renamed to Class A Stock. The Company distributed approximately $90.6 million of the cash proceeds from the Company’s initial public offering to redeem approximately 9.0 million shares of Class A Stock, which shares were then cancelled by GPAC. In addition, the Sponsor agreed to forfeit an aggregate of 1.3 million of the 3.9 million shares of common stock it received at GPAC’s formation (the “Founder Shares”), which forfeited shares were then cancelled by the Company. GPAC issued an additional 4.0 million shares of Class A Stock to investors as part of a private investment in public equity (PIPE financing). In accordance with the terms of the Business Combination, approximately 1.3 million shares of Class A Stock were subject to vesting and forfeiture. The shares of Class A Stock subject to vesting will be forfeited eight years from the Closing, unless any of the following events (each a “Triggering Event”) occurs prior to that time: (i) the closing price of the Class A Stock on the principal exchange on which it is listed is at or above $12.50 for 20 trading days over a thirty trading day period (subject to certain adjustments), (ii) a change of control of the Company, (iii) a “going private” transaction by the Company pursuant to Rule 13e-3 under the Exchange Act or such other time as the Company ceases to be subject to the reporting obligations under Section 13 or 15(d) of the Exchange Act, or (iv) the time that the Company’s Class A Stock ceases to be listed on a national securities exchange. During the year ended December 31, 2020, a Triggering Event occurred as the closing price of the Class A Stock on the principal exchange on which it is listed was at or above $12.50 for 20 trading days over a thirty-trading day period. Accordingly, the shares of Class A Stock are no longer subject to vesting or forfeiture. *Class B Common Stock* The Company has 90.0 million shares of Class B Stock authorized at a par value of $0.0001 per share. Holders of the Company’s Class B Stock will vote together as a single class with holders of the Company’s Class A Stock on all matters properly submitted to a vote of the stockholders. Shares of Class B Stock may be issued only to InnoHold, their respective successors and assigns, as well as any permitted transferees of InnoHold. A holder of Class B Stock may transfer shares of Class B Stock to any transferee (other than the Company) only if such holder also simultaneously transfers an equal number of such holder’s Purple LLC Class B units to such transferee in compliance with the Second Purple LLC Agreement. The Class B Stock is not entitled to receive dividends, if declared by the Board, or to receive any portion of any such assets in respect of their shares upon liquidation, dissolution, distribution of assets or winding-up of the Company in excess of the par value of such stock. In connection with the Business Combination, approximately 44.1 million shares of Series B Stock were issued to InnoHold as part of the equity consideration. InnoHold subsequently transferred a portion of its shares to permitted transferees and exchanged its remaining shares for Class A Stock that it sold. At December 31, 2020, the 0.5 million shares of Class B Stock outstanding were all held by other parties. *Preferred Stock* The Company has 5.0 million shares of preferred stock authorized at a par value of $0.0001 per share. The preferred stock may be issued from time to time in one or more series. The directors are expressly authorized to provide for the issuance of shares of the preferred stock in one or more series and to establish from time to time the number of shares to be included in each such series and to fix the voting rights, designations and other special rights or restrictions. At December 31, 2020, there were no shares of preferred stock outstanding. *Public and Sponsor Warrants* There were 15.5 million public warrants (the “Public Warrants”) issued in connection with GPAC’s formation and IPO and 12.8 million warrants (the “Sponsor Warrants”) issued pursuant to a private placement simultaneously with the IPO. Each of the Company’s warrants entitled the registered holder to purchase one-half of one share of the Company’s Class A Stock at a price of $5.75 per half share ($11.50 per full share), subject to adjustment pursuant the terms of the warrant agreement. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares of the Class A Stock. In no event will the Company be required to net cash settle any warrant. The warrants have a five-year term which commenced on March 2, 2018, 30 days after the completion of the Business Combination, and will expire on February 2, 2023, or earlier upon redemption or liquidation. The Company had the right to call the Public Warrants for redemption if the reported last sale price of the Class A Stock equaled or exceeded $24.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date the Company sent the notice of redemption to the warrant holders. The Sponsor Warrants are not redeemable by the Company so long as they are held by the Sponsor or its permitted transferees. In addition, with respect to the Sponsor Warrants, so long as such Sponsor Warrants are held by the Sponsor or its permitted transferee, the holder may elect to exercise the Sponsor Warrants on a cashless basis, by surrendering their Sponsor Warrants for that number of shares of Class A Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A Stock underlying the Sponsor Warrants, multiplied by the difference between the exercise price of the Sponsor Warrants and the “fair market value” (defined below), by (y) the fair market value. The “fair market value” means the average reported last sale price of the Class A Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of warrant exercise is sent to the warrant agent. All other terms, rights and obligations of the Sponsor Warrants remain the same as the Public Warrants. On October 27, 2020, the Company provided notice to the holders of the Public Warrants that the Company was exercising its right under the terms of the Public Warrants to redeem such warrants by paying to the warrant holders the redemption price of $0.01 per warrant on November 30, 2020. Any exercise of the warrants prior to that date was to be done on a cashless basis, in accordance with the terms of the warrants. During the year ended December 31, 2020, 15.5 million Public Warrants and 4.3 million Sponsor Warrants were exercised or redeemed resulting in the issuance of 7.6 million shares of Class A common stock. At December 31, 2020, there were 8.5 million warrants outstanding all of which were Sponsor Warrants. *Incremental Loan Warrants* In connection with the Amended and Restated Credit Agreement, the Company issued to the Incremental Lenders 2.6 million Incremental Loan Warrants to purchase 2.6 million shares of the Company’s Class A Stock. Each Incremental Loan Warrant entitled the registered holder to purchase one share of the Company’s Class A Stock at a price of $5.74 per share, subject to adjustment pursuant to the terms of the warrant agreement. In May 2020, Tony Pearce or Terry Pearce individually or together ceased to beneficially own at least 50% of the voting securities of the Company. As a result, the exercise price of the warrants was reduced to zero based on the formula established in the agreement. The Company had the right to call the warrants for redemption at a price of $0.01 per Share of Class A Stock if the reported last sale price of the Class A Stock equaled or exceeded $24.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date the Company sent the notice of redemption to the warrant holders. If the Company called the Incremental Loan Warrants for redemption, it had the option to require the holder to exercise the Incremental Loan Warrants on a cashless basis, by surrendering their Incremental Loan Warrants for that number of shares of Class A Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A Stock underlying the Incremental Loan Warrants, multiplied by the difference between the exercise price of the Sponsor Warrants and the “fair market value” (defined below), by (y) the fair market value. The “fair market value” means the average reported last sale price of the Class A Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of Incremental Loan Warrants. On October 27, 2020, the Company provided notice to the holders of the Incremental Loan Warrants that the Company was exercising its right to redeem such warrants by paying to the warrant holders the redemption price of $0.01 per warrant on November 30, 2020. Any exercise of the warrants prior to that date was to be done on a cashless basis, in accordance with the terms of the warrants. On November 9, 2020, upon the exercise of all the Incremental Loan Warrants, the Company issued 2.6 million shares of Class A common stock in exchange for the Incremental Loan Warrants held by the Incremental Lenders. *Noncontrolling Interest* Noncontrolling interest (“NCI”) is the membership interest in Purple LLC held by holders other than the Company. Upon the close of the Business Combination and at December 31, 2018, InnoHold’s and other Class B Unit holders’ combined NCI percentage in Purple LLC was approximately 82%. At December 31, 2020, the combined NCI percentage in Purple LLC was approximately 1%. The Company has consolidated the financial position and results of operations of Purple LLC and reflected the proportionate interest held by all such Purple LLC Class B Unit holders as NCI.
