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.‎
