Abstract
Multi-layer cushion supports are described which may generally comprise a first support having a first contact surface for contacting a portion of a body and a second surface opposite to the first surface, the first support defining a central chamber and a peripheral chamber surrounding the central chamber, wherein the first support is filled with a first gas or liquid and a second support attached to the first support along the first contact surface. The second support may be filled with a second gas or liquid which is relatively more viscous than the first gas or liquid. In particular, the first support may be filled with a volume of air and the second support may be filled with oil which is less than the volume of air.
