This chair is a simplification of the Mart Stam and Breuer cantilever arm chair of 1929 (Standard- Möbel, Thonet Model B34).
Since the continuous tube which forms both the base and the arms also serves to keep the back
verticals apart, the “handlebar” back cross piece of the earlier model is eliminated.
This chair began to be produced by several companies in Italy during the 1960’s. At present, it is one of the most widely sold modern chairs.
