Mies van der Rohe was inspired by the Egyptian folding chair and the Roman folding chair for its design. The chair was made to reproduce the throne and first appeared at an exhibition at the inauguration of the Spanish royal family.
This chair exudes size and class and is light and strong at the same time. The Barcelona chair is widely recognized as the pinnacle of a harmonized strategy to materials, design and workmanship.
In 1950, Mies improved on the original design, resulting in a fully welded object with an additional bracket removed from spot welding. A one-piece frame made of stainless steel offers greater strength and suspension.
In the US, George Nelson's design was popularized. The chair was originally made by hand but was then mass-produced and marketed by Knoll Associates, which now manufactures it in the US and 29 other countries.
Two pairs of connected crossed steel bars represent the seat frame; The front and back legs of the chair are curved, the back legs intersect with the front legs and form a double curve that supports the seat.
