Experience the sleep of your life with a four-layered cooling and supportive latex air gel memory foam mattress. Sabrina comes topped with a ventilated layer of natural latex for exceptional support, while layers of air-flow and gel-infused memory foam keep the air moving and cool for a comfortable night sleep. Sabrina 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 sleepers and delivers welcome relief from the aches and pains of traditional mattresses. Sabrina is CertiPUR-US certified by accredited independent testing laboratories, so you can be confident that the memory foam is made without formaldehyde, ozone depletes, mercury and other heavy metals including 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 knit cover, dark blue polyester mesh and a non-slip bottom with zipper. Box spring or foundation is optional. Slatted bases should be less than 3 in. apart.
