How do you tell if a Butterfly chair is real?

How you tell if a Butterfly chair is real depends on what you mean by the term "real." If by real you mean an authentic Knoll Butterfly chair produced from 2018 and onwards, first look for the Knoll label found under the seat. Compare this label to images found online to begin to assess its authenticity. Then, examine the metal frame of the chair. An authentic Knoll Butterfly chair will be evenly polished and show no imperfections, such as highly visible welding marks. Any flaws will usually indicate that a piece is counterfeit. On the other hand, if by real you mean an original Butterfly chair made by Antonio Bonet, Juan Kurchan and Jorge Ferrari-Hardoy, the answer is that your chair is unlikely to be. The designers only created three Butterfly chairs, which are all part of museum collections. To learn more about the age and maker of your Butterfly chair, consult a certified appraiser or knowledgeable antiques dealer. Explore a range of Knoll Butterfly chairs on 1stDibs.
