Abstract:
An air distribution support surface product includes a vapor permeable material such as a sheet of breathable material, a fluid resistant material, such as a sheet of waterproof material and an intermediate fluid passing material interposed between the vapor permeable material and the fluid resistant material to form a plurality of chambers. One of the chambers serves as a type of fluid retention chamber and another chamber serves as a type of fluid loss chamber. A fluid intake opening may be provided to allow fluid, such as air, to inflate the chambers. In one example, both of the chambers share the intermediate fluid passing material. As such, the fluid retention chamber is formed by the fluid resistant material and the intermediate fluid passing material. The fluid loss chamber is formed by the vapor permeable material and the intermediate fluid passing material.
