The seat and backrest of the Standard chair by Jean Prouvé are available in various types of robust wood, and the chair‘s striking metal frame comes in different colours.‎ This understated, iconic design is a famous classic by the French ‚constructeur‘.‎Materials:- Seat and backrest: oak (natural or dark finish) or walnut (black-pigmented finish).‎- Base: bent sheet steel and tubular steel, powder-coated finish (smooth).‎Chairs take the most stress on their back legs, where they bear the weight of the user's upper body.‎ The engineer and designer Jean Prouvé illustrated this simple insight in his distinctive design for the Standard chair: while steel tubing suffices for the front legs, since they bear a relatively light load, the back legs are made of voluminous hollow sections that transfer the primary stress to the floor.‎Standard is offered with a seat and backrest in wood or as the model Standard SP in ASA plastic.‎ In addition, there is the all-wood Chaise Tout Bois, whose design is very similar to the Standard chair.‎ During World War II, Jean Prouvé responded to the limited supply of metal with a version made entirely out of veneer and solid wood.‎
