Here is a museum devoted to the history and celebration of modern chair design, especially Bauhaus steel tubing approaches.
It is housed on the Tecta campus in buildings designed by Peter and Alison Smithson.
Apparently, the cantilever approach was derived from bicycle steel tubing by Bauhaus designers. It was adapted to the wooden frame on the right by Gropius.
And who knows, you might run into Walter Gropius, Marcel Breuer and Wassily Kandinsky at the Tecta Kragstuhlmuseum !
Chairs by Gerrit Rietveld, with an original from his design shop on the left.
