120 Day Mattress Comfort Guarantee

Mattress industry experts recommend at least 30 nights of sleep on a new mattress to adjust to the feel. Please allow your body to adjust to your new sleep set. If, after 30 days of sleeping on your new mattress and foundation, you are not able to adjust to the proper support, you have up until the 120th day from your original delivery date to make a one-time reselection. The delivery of your reselection must be scheduled within 14 days. You may choose a new mattress of equal or greater value or we will pick-up the mattress and foundation(s) for credit (minus fees). The customer is responsible for paying any difference in price. Mattress and foundation(s) must be undamaged, unsoiled and free of stains. A redelivery fee or pick-up fee will be charged and a 15% preference fee will be deducted from your original returned mattress purchase. This does not apply to mattress and foundations that have been replaced under the manufacturer's warranty.
