ABSTRACT:
The present invention entails a body support structure such as a chair, bed or the like that is provided with an inflated bladder interposed between a plurality of load carrying members and a main frame that allows the plurality of load carrying members to be depressed independently of each other and to, as a group, generally conform to the shape of the load being supported. In the design of a chair and the seat therefor, for example, the chair is provided with two side frames. Each side frame receives and retains an elongated inflated bladder with upper segments of the bladder being exposed. A plurality of independent transversely extending seat members or slats span said two side frames with each seat member or slat about opposite ends resting over and generally supported by said bladder. Thus, the bladder tends to support the respective seat members or slats in a floating-resilient type fashion.
