The Barcelona chair is a chair designed by Ludwig Mies van der Rohe and Lilly Reich, for the German Pavilion at the International Exposition of 1929, hosted by Barcelona, Catalonia, Spain.
The chair was first used in Villa Tugendhat, a private residence, designed by Mies in Brno (Czech Republic).
The frame was initially designed to be bolted together but was redesigned in 1950 using stainless steel, which allowed the frame to be formed with a seamless piece of metal, giving it a smoother appearance. Bovine leather replaced the ivory-colored pigskin which was used for the original pieces.
