Abstract

An inflatable cushion is organized into zones (r, s, t, u) or compartments which are normally isolated from each other. The base (2) of the cushion contains channels (28) which lead from several zones to a flap-type valve. When the flap is extended, the channels are connected through a manifold (36) in the valve. However, when the flap is folded over upon itself, the channels are blocked before the manifold and the zones are isolated. Having separate and isolated zones, the cushion provides improved stability and better serves to maintain the user in a desired posture. A
modification has individual fill valves (10) and stems (8) for each zone and for the manifold.
