Abstract

A foam cushion suitable for use such as with a wheelchair provides a combination of general pressure relief and positioning control over legs of a patient possibly otherwise having reduced or impaired motor control skills. A desired leg position is achieved by separating the legs and supporting them in a generally parallel position. Two base pieces have predetermined upper profiles and are glued to an upper support element having integrated cubic elements for pressure relief. Channels between adjacent cubic elements facilitate flexure of the upper element to conform to the contours of the two base pieces. Relatively high ILD foam characteristics and relatively high foam densities combined with the subject structure give good results for support and for product life, including compression fatigue considerations.
