Sleep is more than just a mattress. Pillows and mattress protectors are a VERY important part of the sleep experience! If you aren't completely satisfied and comfortable on your new mattress after sleeping on it for at least 30 days, you have 6, 12 or 18 months to exchange it (depending on which plan you choose). If you select one of greater value, then simply pay the difference. No questions asked and no fees involved. It's that simple!
