The cantilevered tubular chair was originally designed by the legendary Dutch modernist architect Mart Stam as the S43 model, and from the 1920s it was produced and sold by the Thonet company in Germany.

However, this particular piece was produced in Czechoslovakia by the Gottwald furniture company in the 1930s under the Thonet licence. This is a fine example of the radical aesthetics of the Bauhaus. Original, simple and functional at the same time, it represents the philosophy of the avant-garde movement. Overall, the tubular frame is in very good vintage condition with minor signs of wear. The veneered plywood has recently been renovated to the highest level using original techniques and finishes, reviving the beautiful natural pattern of the seat and backrest which were then hand finished in Nitro varnish. The chair was found with a chipped corner on the upper left side of the backrest. It has been remodelled to its original form.
