Scope note:

Cantilever chairs that are considered a major development in modern furniture. Mart Stam created the first experimental models with gas pipes and flanges and developed the principle of cantilevering chair supports without four legs. Later innovations allowed the use of tubular steel. Others such as Marcel Breuer and Mies van der Rohe designed their own variations on the principle.
