The asymmetric case built to extend one of the legs reminds to the handle of the scythe or the number 7, a Chair in wood.

HISTORY
In 1973, Pierre Chapo developed the T 21 table and the S 31 stool and then completed the “converging lines” furniture range with the introduction of the S 34 chair. The complexity of the base, composed of legs converging together, forced him to extend his research, notably in the field of plane geometry, to obtain a perfect construction.

The diameter of the S 34 seat is too small to ensure the structure’s stability, and too big to borrow the S 31 stool’s tripod base. Pierre Chapo solved this problem by thinking of a dihedral angle laid on the ground, which receives the seat in the middle and the back at the top. This section rests on a transverse leg consolidated by the two other legs, assembled together in such a way as to distribute the weight in relation to the four converging legs. The last leg completes the assembly by resting on the first at a dihedral angle. The polygonal seat is also exactly positioned to distribute the load of the seated person
