Abstract
A utility chair having spaced apart leg members, a frame supported by the leg members having a base portion and a back portion, the improvement consisting of a one-piece blow molded hollow back member and a one-piece blow molded hollow seat member adapted to be mounted on the base portion. The seat member comprises integrally formed front, back, top, and bottom walls. The top wall is vertically spaced from the bottom wall and is yieldably deformable. An upstanding reinforcing member is integrally formed with the bottom wall for providing rigidity to the seat member while at the same time permitting the top wall to flex downwardly a limited distance upon downward forces being exerted on the upper surfaces of the seat, thereby providing a cushioning effect.
