In 1934, Gerald Summers designed a very original “armchair”, that was obtained from the curvature of a single sheet of plywood. This was the starting point of this armchair, consisting of two symmetrical pieces, each of them born from a single sheet of wood. The difficulty consisted in finding the right proportions in the cuts so as to assure the chair a stable position after bending each part (arms, legs, back). A complication was the desire of not working on a basis simply cylindrical. The final result gives honour to Mr. Summers whose lesson hasn’t been forgotten.
