The chairs support more load on the hind legs, where they must support the weight of the upper body. Jean Prouvé applied this simple principle in the Standard Chair edited by Vitra in a significant way. While for the front legs, with a relatively weak load, is enough with a steel tube, the rear legs have been designed as a bulky hollow body that transmits the load to the ground. Details: Seat and back in oak (natural or dark finish) ), walnut (black pigmented finish). Frame in sheet steel, smooth powder coating.
