The S 33/S 34 was designed by Mart Stam and belongs to the product range of the German furniture manufacturer Thonet. Experimenting with industrial steel pipe brought the designer Mart Stam in the mid 20s ultimately to the idea of a curved frame combined with leather.

Design Story

The Dutch designer and architect Mart Stam was a pioneer of modern furniture design. His experiments in the early 1920s with industrial pipes brought him in 1926 to the development of the S 33, the first cantilever chair. Mart Stam made a significant contribution not only to the Weissenhof Estate project in Stuttgart, but also aroused an international sensation. During his lifetime, Mart Stam worked not only at the Bauhaus Dessau, but also oversaw projects on virtually every continent, projects which continue to attract even new admirers. His genre defining cantilever chair is marketed today by the German manufacturer Thonet, and remains his most famous product - if only because the design and engineering possibilities and thinking to construct a chair without back legs was unknown before Stam developed them. The S 33 is distinguished thanks to its teetering structure through a sense of convenience and ease. The S 34 in turn provides with its armrests an additional level of comfort, and an even more solid seating position. Regardless of which one chooses, both Thonet chairs, thanks to their mix of timeless design and elegant materials, genuinely enliven and enrich any room.

IMM Cologne 2016: Thonet All Seasons Collection

...And that the All Seasons chairs can be used indoors and out is not just because the Thonet sales team tell you they can, but because the All Seasons collection presents new versions of the S 33, S 34, S 35 & S 533 chairs - established Thonet classics and all originally intended for indoor domestic use... The decision for the S 33, S 34, S 35 & S 533 was ultimately made on the basis that they are self-contained in their construction, with, for example, the S 32 the frame requires the wooden backrest for its stability, with the All Seasons collection we have exclusively steel tube chairs with a woven synthetic mesh for backrest and seat...
