ABSTRACT:
The invention relates to a two-piece collapsible chair, one of which pieces provides a backrest and rear leg element, and the other of which provides an inverted seven-shaped seat and frontal leg element. Both elements are constructed so that upon erection of the chair the inverted seven-shaped seat and frontal leg element engage and interlock the backrest and rear leg element about the vertex of the seven. Seating pressure biases the seat so as to enhance the interlocking engagement of the two pieces.
