Enjoy perfect sleep with a triple-layered cooling memory foam mattress. Caroline comes topped with an open cell layer of air flow memory foam that keeps air moving, while a second layer of gel-infused memory foam further ensures a cool and comfortable night sleep. Caroline is a responsive mattress that 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. Caroline is CertiPUR-US? certified by accredited independent testing laboratories so you can be confident that the memory foam is made without formaldehyde, ozone depleters, mercury and other heavy metals, PBDEs, TDCPP or TCEP (?Tris?) flame retardants, and is low on VOC. 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 a removable stretch cover, gray polyester mesh and a non-slip bottom. Box spring or foundation are optional. Slatted bases should be less than 3" apart. Set Includes: One - Caroline 10" Full Mattress
