AFFORDABLE REST, CERTIFIED QUALITY - Experience the luxury of high-quality CertiPUR-certified foams without breaking the bank. This fiberglass-free mattress offers unparalleled value and is developed for quality, durability and ultimate comfort. EXPERTLY PACKAGED - Our technology allows this mattress to be efficiently compressed into one box that’s easily shipped and maneuvered into the bedroom; simply unbox, unroll and this mattress does the rest, expanding to its original shape within 72 hours. Please allow 24-72 hours for your mattress to regain its original shape. Memory foam will expand faster in a warmer room and may take longer to regain shape from its compressed state in colder temperatures. Expansion time will vary based on surroundings. Worry-free 10 year limited warranty included; twin mattress supports a maximum weight of 250 lbs, while all other sizes can support up to 500 lbs
