Abstract

Abstract A body support system, such as a chair or bed, having a pair of support rails and a plurality of rows of flexible cords. The cords are generally perpendicular to the rails and parallel to each other. A plurality of elongate rigid support links are rigid supported from adjacent rows of cords. Alternate links along each row extend in opposite directions for providing a continuous, conformable low interface pressure, body support surface.
