The naming dispute over the Barcelona chair and its companion pieces goes back to the 1920s, when Mies van der Rohe designed the chair, the stool/ottoman, coffee table, and daybed, for the International Exposition in Barcelona, Spain, for visiting Spanish royalty. It was kind of a big deal.
Because it looks so cool, Knoll bought the rights to the furniture and began selling it under the trademarked name, Barcelona, to fans of modern furniture all over the world.
But since the copyright to the design has expired, it means no one owns the rights to the design itself. Anyone can make a knockoff and charge whatever they want. Which is great for most of us, because Knoll charges a few thousand dollars per piece of furniture that bears the Mies van der Rohe name. And the only difference between the "authentic" piece and the knockoffs is the name of the designer stamped into each piece.
So the cheaper Barcelona stool replica models are sold under the names "Barcelona-style," "Exposition," or "Pavilion," reflecting its history while avoiding the name dispute.
So, where do we get one?
