ABSTRACT:
A support cushion has a flexible, airtight casing having a support layer on one side defining a support surface for being engaged by a portion of a body to be supported. A resilient layer of foam is disposed within the casing generally coextensive with the casing support layer support surface for normally urging the casing toward an expanded condition. A fluid-filled pad is positioned within the casing adjacent the additional foam material. A valve is mounted to the casing for communicating with the interior of the casing and is operable for preventing or permitting flow of air through the valve into and out of the casing.
