ABSTRACT:
A folding chair of the type having generally rectangular, open, inner and outer frames pivotally connected together and nestable one within the other, a seat panel pivotally secured to one of the frames, and a seat back in the form of a generally rectangular open frame which is pivotally secured to one of the inner or outer frames and nestable therewith so that the chair may be folded into a very compact unit of minimum dimensions. In order to provide comfort to the user and additional rigidity to the structure, there is provided a rigid seat back panel pivotally secured along one edge to the seat panel and having its opposite edge removably received in a slot in the upper portion of the seat back frame. When the seat back is pulled forwardly from its fully extended, upright position, the back panel will be pulled out of the slot so that the seat back frame may be passed over the seat panel and folded together with the seat panel and the inner and outer frames.
