Technology becomes furniture; a striking invention becomes an elegant interior design object. Ludwig Mies van der Rohe was the first to provide the cantilever chair with aesthetic lightness and to relate it to its environment with curved lines. In the run-up to the Weissenhof Estate exhibition, which he organised, Mies van der Rohe became familiar with the principle of the cantilever chair thanks to Mart Stam. As new as this approach may have been, Mies van der Rohe was not impressed with its first implementation by Stam. He immediately answered the technological innovation with his own aesthetic solution, which he was able to present in 1927. The S 533 is one of the first cantilever chairs, and it defines the surrounding environment with its large, elegantly curved circular tubular steel form. Targeted restriction with regard to the use of materials, elegance of lines, and transparency in its effect are the characteristics of S 533.
