THONET bar stool • Programme S 43 H
Simplicity that works its effect everywhere: Mart Stam took the hind legs off a chair that had been shaped along similar principles for centuries. Through evolutionary refinement, this produced a piece of seating furniture that cuts a fine figure anywhere understatement and quality are called for. In his furniture designs, Mart Stam was concerned with high utility and economy, both aesthetically and materially. This resulted in the clean-lined shape, the clear construction, and improved seating comfort. Stam achieved the greatest possible reduction with the cantilever S 43 by combining the tubular steel frame with moulded wood parts for the seat and back. Its pure, restrained shape makes this cantilever chair an exemplary design in the spirit of modernism. The artistic copyright for the strictly cubic, legless chair now belongs to Thonet. The Natural Sciences reading room of the German National Library in Leipzig was already furnished with the S 43 cantilever chair in 1933. More than 70 years later, Thonet supplied new S 43 chairs to complete the set. Such longevity and sustainability are only found in tubular steel furniture of the high quality typical of Thonet. The programme is extended by the swivel chair variants S 43 Atelier (DR), the S 43 H bar stools, and the S 43 K children's chairs.
The THONET S 43 H brings the S 43 cantilever chair up to bar height: chrome-plated tubular steel frame, seat and back in moulded plywood. It is available unupholstered (S 43 H) and with mirror upholstery (S 43 PVH). The frame is available powder-coated for a surcharge, and the moulded wood parts in further stain shades, in oak, or with opaque lacquer. POM plastic glides or felt glides are included.
