Abstract: A seat cushion with a carrying handle has a multi-cellular foam interior structure for holding and releasing air encased within an air impermiable covering and at least one valve member secured to the covering and having a conduit extending through the covering into the foam. The handle may span a front indented portion in which the valve is located so as to span the valve. The cushion may have a second valve permitting air to enter into but not exit from the foam so as to re-inflate the cushion gradually. The first valve permits air to exit the foam when it is open while a compressible force is applied to the foam. Thus, when a person sits on the cushion and opens the valve, air within the cellular structure of the foam is expelled in accordance with the force applied and the foam is shaped to that of the user's compression applying members. The second valve permits re-inflation of the cushion gradually if the user fails to open or actuate the first valve when removed from the cushion for an extended time.

Abstract: A motorcycle seat has a shape forming base on which a selectively deformable cushion is positioned and covered by an exterior covering, the cushion having a foam material encased within an airtight bladder. A valve member located externally of the covering has a conduit which extends through the bladder in sealed fashion and terminates within the foam material. The valve may be selectively opened, and when open while a compression force is applied on the foam, air is expelled from the foam, and if the valve is then closed the foam is formed into the shape of the force applicator. With the valve closed, movement upon the cushion redistributes the air within the foam accordingly. When the compression force is relieved and the valve is opened, the cushion takes on its original shape.
