How do I tell if a Cesca chair is real?

To tell if a Cesca chair is real, examine its tubular metal frame closely. Real Cesca chairs have smoothly polished, welded ends, while reproductions often have end caps that are fitted onto the frame to hold it together. In addition, turn the chair over and examine the label under the seat. A genuine Cesca will have Marcel Breuer's signature as well as the Florence Knoll name. If you're unsure about the authenticity of a chair, have a certified appraiser or knowledgeable antique dealer evaluate it. Find a diverse assortment of Cesca chairs on 1stDibs.
