The targeted restriction in the use of materials, elegance in the lines and transparency in the effect are the characteristic properties of the S 533. It owes its special comfort to constant elastic flexing. This effect results from the fact that Mies van der Rohe conceived the front part of the tubular steel frame as a big bow made of spring-hard tubular steel. While most of the de- signs from the 1920s were rather simple and functional, this chair clearly communicates the signature of the architect: his design combines functionality and comfort with timeless aesthet- ics. The chair was first presented in the Weis- senhof-Siedlung in 1927.
