How do I spot a fake Barcelona chair?

To spot a fake Barcelona chair, start by checking the base. A genuine chair will feature a production number and Mies van der Rohe's signature. You can compare these markings to images published by trusted online resources to evaluate the authenticity of a chair. Next, count the number of panels on the upholstery. A real Barcelona chair will have 40 panels, but replicas may not. Also, the upholstery on authentic Barcelona chairs is a single piece to which piping is then applied. If you notice seams that indicate the maker utilized multiple pieces of hide or fabric, you're likely looking at a reproduction. When in doubt, seek the opinion of a certified appraiser or knowledgeable antique dealer. Explore an assortment of Mies van der Rohe Barcelona chairs on 1stDibs.
