Abstract
An inflatable multi-layer body support cushion, adapted to buffer or dampen the fluid reaction to forces applied to the upper surface of the cushion, includes a plurality of adjacent cells of generally hourglass configuration defined by vertically stacked upper and lower chamber portions and medial neck portion. The laterally adjacent chambers are interconnected for the intralayer fluid flow therebetween. The vertically adjacent chambers are interconnected in the neck portion of the cells by orifices which control the interlayer fluid communication between the upper and lower chambers.
