Take a deep breath and exhale because you?ve found your pathway to that perfect sleep. Topped with a gel-infused surface to keep your body climate steady, the mattress dissipates your body heat while quickly conforming to your weight and position. Sleep peacefully with an open cell memory foam solution that relieves pressure points, reduces bounce between two sleepers, and delivers welcome relief from the aches and pains of traditional mattresses. Foam is CertiPUR-US? certified so you can be confident that the flexible polyurethane foam inside the mattress meets CertiPUR-US? standards for content, emissions, and durability, and has been analyzed by independent, accredited testing laboratories. The mattress comes vacuum-packed and rolled to fit into an easily portable box. It takes 2 to 4 hours for the mattress to expand most of the way, and a day to expand fully. Includes one full mattress and a removable stretch knit diamond patterned cover. Box spring or foundation are optional. Slatted bases should be less than 3? apart. Set Includes: One - Aveline 6" King Mattress
