The Most Chair-like of Chairs

Standardization, Practicality, and a Classic: The Standard Chair

A standard is the level ordinary people recognize and accept in a given situation. Creating one entails countless attempts and experiences, repetition and discussion. Once a standard is established, what follows becomes smoother—and it becomes a foundation that opens new possibilities. The Standard Chair is a case in point. Its prototype was the Chaise no. 4, which Jean Prouvé created in 1934. Building on it, Prouvé accepted what circumstances demanded, adapted to new conditions, and gradually developed a better chair. His principles throughout were firm: a chair must be sturdy and comfortable; surfaces that meet the body should be soft; production should be rational; and the chair should sit harmoniously within its space. Because his standards were unwavering, the Chaise no. 4 retained its identity and value through repeated changes. Prouvé paid particular attention to the rear of the chair, where the seat meets the back legs. Judging that this part, which bears the greatest weight when seated, needed reinforcement, he devised legs with a triangular structure. Thanks to the stout rear legs, the load is distributed according to each leg's strength, forming a solid structure. A thorough functionalist, Prouvé believed a chair must be chair-like: furniture for sitting, and that a maker's duty was to create practical furniture for the many. In that sense, these somewhat rugged triangular legs epitomize his design philosophy. This is why the Standard Chair has become 'more than a chair' today—a classic built on a story of focusing on the essentials and steadily advancing one's principles and intentions.

The Origin of the Standard Chair: Chaise no. 4

The Chaise no. 4, the foundation of the Standard Chair, was created as office furniture. It was the first to feature triangular legs made of folded sheet metal, with a thick solid-wood seat whose sitting surface was smoothly finished. For the backrest and seat, the atelier collaborated with Luterma, then a pioneer in plywood furniture, raising both productivity and quality. At the time, Ateliers Jean Prouvé had some twenty skilled workers producing a wide range of goods in concert. With the arrival of Jean Boutemain and Jean-Marie Glatigny, a separate design studio was established, and specialists in tracing, pressing, extrusion, and welding were brought in to reinforce production. The recruitment of Émile Marchal, a former aircraft mechanic, further strengthened its technical expertise, while a three-meter press, shears, and an extrusion table accelerated the work. With the Chaise no. 4 as its model, the atelier received tenders from hospitals, government offices, and schools; a project with the CPDE (Compagnie Parisienne de Distribution d'Électricité), the Paris electricity company, proved especially meaningful. The chair evolved once more: armrests were added, and the seat and back were cushioned and upholstered in artificial leather. This design later went through further changes, giving rise to various office chair versions. The CPDE project became a decisive moment in which Ateliers Jean Prouvé won recognition as both designer and manufacturer in mass-produced furniture.

A Chair Entirely of Wood: The Chaise Tout Bois

The Chaise tout bois is an example of remarkable adaptability under extreme manufacturing conditions. With metal hard to procure during the war, the chair was made—as its name suggests—entirely of wood. Notably, production was entrusted to Vauconsant, a manufacturer near Nancy. Wooden chairs with slightly different joinery were produced in variety at this time, made possible by the high proportion of studio workers free to attempt different approaches. After the war came a version that could be assembled and disassembled: the Chaise bois démontable, built of wood but using metal parts where the legs join the seat supports. Through it all, the inverted-triangle structure of the rear legs never wavered—a glimpse of Prouvé's idea, and his obstinacy, in putting a chair's solidity first in any circumstance. The Chaise tout bois is also striking as the only chair Ateliers Jean Prouvé aimed at the consumer market. It gained further significance in 1947 by winning an award at the French furniture competition organized by the Ministry of Industrial Production to build a furniture market serving society at large, including the disadvantaged and refugees. That award, in a competition with such intent, speaks for Prouvé's vision of practicality and the common good.

The Start of Mass Production: The Chaise Cafétéria no. 300

After moving the factory to Maxéville in the late 1940s, Jean Prouvé faced many questions in running the company. As an engineer he needed to develop models that met the needs of households and public institutions, and to secure enough production to maintain steady stock; but he also considered it vital to build a commercial distribution structure so the furniture division could stand on its own. It was then that Steph Simon joined—someone who could ease Prouvé's burden. A machine-company operator with a wide network, Simon became the agent for the atelier's furniture, producing brochures to appeal to public institutions and colonial markets and proposing improvements in materials and convenience. The Chaise Cafétéria no. 300, introduced at this time, was a 'démontable' version of the earlier wooden knock-down chair, now made of metal. The front and rear legs were joined by welding steel tube to triangular columns of folded sheet metal. The parts amounted to a seat and back, two leg frames connecting front and rear legs, two rods linking the frames while supporting the seat, and two screws. The joining of seat and frame was upgraded as well: where the Chaise no. 4 had notched its triangular columns to fix the seat, the Cafétéria no. 300 presents a seamless profile, its center stamped—a process of pressing metal into shape or piercing it in a mold—to receive the screw, completing the triangular structure with greater refinement. The chair was mass-produced for the cafeteria of the Cité Internationale Universitaire de Paris and sent, under the name 'Tropique,' to the Air France headquarters in Brazzaville, Congo. Prototypes applying aluminum casting, drawing on the influence of parent company L'Aluminium Français, were also attempted; high production costs kept them from full production, but versions with aluminum seat and back were later released. It calls to mind Prouvé's tenacity: where chairs were concerned, research and development never stopped.

The Birth of the Standard: The Chaise Métropole no. 305

Before long, the Cafétéria chair evolved once more into the Chaise Métropole no. 305. Its defining feature was a one-piece frame in place of assembly, making production far more efficient in both process and cost. Joining the front and rear legs by piercing the center of the triangular column, inserting the front leg, and welding it from inside the tube was also a departure from earlier methods. A look at this detail reveals how the chair is joined—a glimpse of Prouvé's preference for designs that lay the production process bare. Used in places from the French steel industry's association to the offices of the atomic and alternative energy commission, the Métropole no. 305 is also the version that best displays the colors of Prouvé's palette. Prouvé gave it the name 'Standard Chair,' believing it the chair that best represented his design. After the Maxéville factory ceased production in 1951, it was produced and distributed through Steph Simon until 1969. Simon advised Prouvé closely on the direction of the business, yet one plan was never accepted: putting Prouvé's name front and center for marketing. Prouvé felt that personal fame would disturb the balance of design and manufacturing and overshadow the achievements of his fellow workers. He sought only to develop efficient production methods suited to circumstance and to remain faithful to making practical objects for the public realm through mass production. Perhaps that is why this chair he named 'Standard' carries the air of a plain declaration, much like the man himself.
