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.
