ABSTRACT:
The specification discloses a chair having a seat seated on spaced side rails above an auxiliary seat supporting surface which is spaced slightly below the seat and which shares the load imposed on the seat by a person sitting in it with the side rails and their supporting stretcher, yet allows the seat to give slightly so that the seat feels comfortably yielding.
