S 43 PVDR Swivel upholstered chair with castors

S 43 PVDR is a swivel chair with castors and flat upholstery designed by Mart Stam.‎

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 seating 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 with no rear legs”.‎
