ABSTRACT:
A cushion system for supporting a body such as a seated person at risk of developing pressure sores. An array of one or more foam members is biased such that each foam member exhibits a substantially constant force per unit area when supporting the body. The bias may be passive, by choice of foam characteristics, and additionally, may be applied actively by providing a gas to the foam and controlling the pressure of the gas in response to the pressure conditions at the interface with the supported body.
