Although it cannot be considered innovative in a narrow sense, this model is unquestionably Breuer’s work. During this same period, other designers were working on the continuous tubular cantilever chair, which gave rise to legal disputes around attribution. In a lawsuit filed in 1929 the German High Court awarded attribution to the Dutch designer Mart Stam. Breuer?s version with the beechwood seat and back was nevertheless a brilliant solution to the necessity for the structural stiffening of the frame. In the hemp or wicker versions designed by Mart Stam, Anton Lorenz and Mies, metal bars introduced under the seat and behind the back provided the strength to keep the legs separated. In the 1960s, the chair was renamed „Cesca“, as a tribute to his daughter Cheska.
