ABSTRACT:
A chair adapted to be packaged, transported and sold in knocked-down (disassembled) fashion and constructed of extremely lightweight and inexpensive components while providing a chair of more than adequate structural strength for normal usage. A pair of uprights are formed from an extremely lightweight relatively soft plastic material such as foamed polystyrene (polyurethane foam) preferably having imbedded therein either cardboard discs or a flat cardboard sheet generally conforming to the outline of each upright for yielding added structural strength; the uprights each being provided with coaligned openings for receiving paper tubes to collectively define an assembled chair frame. The discs or the sheet define the base of each opening. A one-piece fabric cover is stretched over the frame and is tied along the bottom serving as a means for securing the frame pieces in the assembled state, as well as maintaining the fabric spanning the seat and back portions of the chair sufficiently taut to assure comfortable seating thereupon.
