ABSTRACT:
An ergonomic support in the nature of chairs, sofas and the like, includes flexible and resilient posterior and lumbar supporting portions having non-planar, contoured shaped surfaces which comfortably conform to the body. The supporting portion is shaped to form a plurality of cantilevers which automatically adjust and conform to body movement without mechanical parts, as opposed to adjusting the body to conform to the supporting portion.
