TUBULAR STEEL CLASSICS S 43 – AN EXEMPLARY DESIGN IN THE SPIRIT OF MODERNISM In all of his furniture designs Mart Stam relied on straightforward forms, an aesthetic economy of means in the construction and the benefit of improved sitting comfort. In the case of S 43 he combined the tubular steel frame with moulded plywood shells for seat and back and thus created an absolute reduction. Due to the comfortable flexing effect of the frame, upholstery is unnecessary. Its clear, reserved form makes this cantilever chair an exemplary design in the spirit of modernism. Today, Thonet owns the artistic copyright for this strictly cubic chair without back legs.   Frame tubular steel chrome-plated or lacquered in various colors (not stackable). Moulded plywood seat and backrest in stained beech, lacquered or with structured coating in 11 different colors.The cantilever chairs from program range S 43 with a set in TP 29 black (stain) or RAL 7021 (lacquer or structured coating) as a standard have black rivets on the seat and backrest. All other colors are assembled with silver rivets.
