TEMPUR® material is "open cell" and polyurethane based. The open cell structure is breathable and promotes air flow. Air is pushed out of the TEMPUR® cells when pressure is applied. When the pressure is removed, the cells automatically "reinflate" to return to their original shape. This breathable structure also promotes the dissipation of heat to keep individuals cool and comfortable. All products produced by Tempur-Pedic have a minimum density of 5.3 lb/ft3. The Base Layer of our mattresses provides support to the TEMPUR® components. The AirFlow System™ Base Layer increases circulation to the TEMPUR® components Additional Base Layers provide additional cushioning and support
