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.

- a unitary backrest and rear leg portion having a compressible brace transversing the width of the unitary structure;
- and a reversed seven-shaped seat and frontal leg portion being compatible with the transverse brace portion of the backrest rear leg portion so as to interact with the compressible brace to form an interlocking sleeve, whereby a secure chair structure is formed.
