Claim:
A pneumatic foam cushion for use within a vehicle seat comprising: a foam member having a contoured, at least partially curved, outer surface; a first impermeable member characterized by a first contoured, at least partially curved, shape substantially the same as a portion of said contoured, at least partially curved, outer surface of the foam member when not in contact with said foam member; and a second impermeable member characterized by one of said first contoured, at least partially curved, shape and a second contoured, at least partially curved, shape substantially the same as another portion of said contoured, at least partially curved, outer surface of said foam member when not in contact with said foam member; and wherein said first and second impermeable members are positionable in contact with said respective portions of said contoured, at least partially curved, outer surface of said foam member to form an impermeable layer substantially coextensive with said contoured, at least partially curved, outer surface such that said foam member retains said contoured, at least partially curved, outer surface and said first and second impermeable members retain said respective contoured, at least partially curved, shapes when positioned in contact with said outer surface of said foam member to form said impermeable layer, said impermeable layer permitting selective pressurization and depressurization of said foam member within said vehicle seat.
