^{^}You may exchange your mattress once, with a return delivery fee of $99.99* and a restocking fee of $149.99, and receive, as credit toward the purchase price of a different mattress, the purchase price of your original mattress. If you still aren’t absolutely satisfied with your new mattress, you can return it with a return delivery fee of $99.99* and an additional restocking fee of $149.99 and receive, as a refund, the purchase price of your new mattress. Your refunded purchase price will be further reduced by any state use taxes that we are required to apply. Mattress Firm is unable to exchange or refund stained, unsanitary or damaged mattresses under the 120 Night Sleep Trial®. That’s why we highly recommend using a waterproof mattress protector to help keep your new mattress clean. In addition, we recommend keeping all original tags on your mattress. If you remove the law tag from the mattress or foundation, it will void the 120 Night Sleep Trial®.
