Chaise Tout Bois is the only chair by the French 'constructeur' and designer Jean Prouvé that is made entirely out of wood. The design is very similar to Prouvé's famous Standard chair, but wood was substituted for the metal base due to the scarcity of metal during the Second World War. The form of the Chaise Tout Bois articulates Prouvé's intention to provide added strength at the transition point between the seat and backrest, where the load weight of the human anatomy is greatest. The profile of the rear frame section – back legs and backrest support – makes reference to this load transfer and is a typical characteristic of Prouvé's designs for both furniture and architecture. Prouvé created several prototypes of this chair during the war for the purpose of testing its structural strength as well as the joints, leg position and connection between the seat and back. The chosen type of wood depended on what was available at the time. After the war, there was once again a sufficient supply of oak, which due to its hardness and strength was commonly used in France to construct ships and cathedral roofs. As these properties are also ideal for an all-wood chair, the Chaise Tout Bois was ultimately made out of oak and plywood – also offered in dark-stained versions when requested by Jean Prouvé's customers. In 1947, Prouvé won an award for the Chaise Tout Bois in the 'Meubles de France' competition. The concept of the competition was to find attractive, high-quality, mass-produced furnishings to meet the post-war needs of society – particularly refugees and young married couples.
