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.
