These chairs are the first cantilever chairs in furniture history. They were used for the first time in 1927 in the Weissenhof-Siedlung in Stuttgart. Starting in 1925, Mart Stam experimented with gas pipes that he connected with flanges and developed the principle of cantilevering chairs that no longer rest on four legs. He thus created a construction principle that became an important building block in the history of modern furniture design with its formal reservation. In the beginning, Stam was not yet focused on the flexing effect of the bent tubular steel; rather, he was interested in the clear form, which perfectly fit in with the modern buildings of the time.
