About chair 14
Michael Thonet experimented over the years to create the first mass-produced chair that could be sold at a reasonable price (cheaper than a bottle of wine). His ambitions were particularly daring. Alice Rousthorn writes in the New York Times:
“When the No.14 was launched in 1859, it was the first piece of furniture to be both attractive and inexpensive enough to appeal to everyone from aristocrats to schoolteachers. By 1930, some 50 million No.14s had been sold, and millions more have been snapped up since then.”

Bentwood chair is also known as bistro chair. Its construction consists of six pieces of beech that are heated with steam, pressed into curved cast-iron molds, and then dried to the desired shape. Later versions had two diagonal supports added on each side to help secure the seat and backrest.

What makes chair No.14 so special? First, this chair satisfies its predetermined purpose, as every well-designed object must do. Second, it looks and feels outstanding. The German furniture designer Konstantin Grcic said:
“It’s one of the most beautiful chairs there is, and it has exactly the right weight. When you pick it up, it feels perfect. That’s an important aspect of chair design that’s often overlooked.”
Thonet chairs are still widely used today and are considered to be some of the most popular chairs ever made. More than 180 years after their inception, Thonet chairs can be found in several restaurants, cafes, bars, bistros, boutiques, and homes around the world. Bentwood chairs have belonged to many famous people: world leaders, artists, scientists, and many others, such as Albert Einstein, Joseph Stalin, Pablo Picasso, and Henri de Toulouse Lautrec. In fact, in Lautrec’s “At the Moulin Rouge”, you can identify two Bentwood chairs in the painting.

Industrial Design and Mass Production
During the 1851 World’s Fair in London, England, Thonet received a bronze medal for his Viennese Bent Wood Chairs. His fame continued as an international breakthrough and he was awarded a silver medal at the next World’s Fair in 1855 in Paris, France for his famous No. 14 chair. The Bentwood Chair. Production methods were improved and the demand for his chairs made it possible to acquire a new factory in Koricany, Moravia in 1856. Chair 1859 Nr. 14, also known as Konsumstuhl Nr. Chair # 14 or Coffee Shop # 14 is considered a Chair of Chairs. It is said that over 50 million chairs were produced before 1930. The Thonet chair is considered to be the very first mass-produced chair.

How is it made?
The Model 14 Bentwood Chair is made up of just six components combined with a few screws and nuts. Initially, looking for simpler and cheaper means of production, Thonet used folded veneers glued together and held together in what is called “Jigs”. This proved to be a labor-intensive method, and the wood could only be bent in one direction. By adopting this method through further cutting, twisting, and ‘buffing operations, Thonet was able to obtain 3-dimensional curves with oval sections. His quest to get rid of glue led him to his revolutionary solution: a solid piece of steamed wood and a metal strap could be folded together without breaking the wood. Once dry, the wood would retain its new shape.

Therefore, a stronger chair was made with fewer pieces, fewer joints, and screws that replace the glue. In 1856, this modern and original process was patented by Thonet’s son, Gebrüder Thonet, and mass production followed. The design has remained virtually unchanged for over 150 years. Classic and timeless, indeed.
