Despite its name, this design was actually born in Germany. During the International Exposition in 1929, the country offered this entry as an ode to the Expo's host city, Barcelona, Spain. The chair was a collaboration between two great design minds, Ludwig Mies van der Rohe and his longtime partner and companion, Lilly Reich, a designer and architect in her own right. It is often cited as an icon of modern design. Its inspiration came from campaign and folding chairs of ancient eras. With a stainless steel frame, and a cushioned, Bovine-leather seat and back, it's a popular choice of design-obsessed homeowners. The chair has been manufactured by Knoll since the 1950s.
