<sup>††</sup>For 60 and 72 months in-store purchases taxes and delivery fees must be paid upfront and cannot be charged to your Mattress Firm credit card; upfront payment of taxes and delivery fees will not reduce monthly payment or amount financed. Qualifying purchase amount, less any applicable downpayment must be on one receipt. No interest will be charged on the amount financed and equal monthly payments are required on such balance until it is paid in full.
