ABSTRACT:
A chair construction of two separate yet complementary members. The first member includes two symmetrical, oppositely facing and substantially parallel side pieces held rigidly in relative position. A backrest may be provided by a first series of parallel and spaced apart slats which are secured rigidly and aligned transversely to even forward edges of the parallel side pieces of the first member. The first member also includes structure defining a gap below the backrest which has a vertical height generally the same as the depth of the side pieces. The gap is further defined by two transverse slats attached to rear edges of the side pieces. The second member includes two elongated side pieces which are substantially symmetrical with the side pieces of the first member and which are spaced apart for a distance sufficiently less than the side pieces of the first member so that the side pieces of the second member fit closely inside the side pieces of the first member. The side pieces of the second member are held rigidly in relative position by cross pieces which may also provide the seat element of the chair construction. Preferably, the seat element is provided by a second series of parallel, spaced apart slats which are aligned transversely and secured rigidly to the even upward edges of the side pieces of the second member along the front portion of the second member. Thus, the side pieces of the second member may slip through the gap of the first member to a position where the seat adjoins the back to provide the chair in its useful position. Alternatively, the second member may be slipped inside of the first member for storage and carrying purposes.
