Sitzmöbel B9 by Thonet, also known as the chair of Le Corbusier, was not designed by Le Corbusier but by Michael Thonet, the Thonet factory owner, at the end of the nineteenth century. Le Corbusier was fond of it and used it in many of the houses he designed and took it for his own use, actually at his own apartment, choosing the white ones.

Because the seat of this chair is bigger than usual, it makes it sit comfortably and it is very lightweight, so it makes it easy to move. It is suitable for architects or artists working in the studio a lot.

Le Corbusier even said that this chair is a masterpiece both in terms of assembly, construction, and practical use.
