How can you tell a fake Egg chair?

To tell a fake Egg chair, look for its tag. Chairs produced in 2010 or later will have a red tag, while older pieces will display a brown one. Although the tag designs have changed over the years, nearly all Egg chairs show the correct “Republic of Fritz Hansen” logo. Some will also feature a serial number, which you can cross-reference with information shared on trusted online resources for authentication purposes. Next, look at the stitching on the upholstery. If you notice any creasing, folds or wrinkles, your chair is likely a knockoff. Finally, get a measuring tape or use a smartphone measuring app to check the dimensions of your chair. An authentic Egg chair will measure 42.1 inches (107 centimeters) high by 33.9 inches (86 centimeters) wide, with a seat height of 14.6 inches (37 centimeters). Chairs that don't fit these specifications are unlikely to be real. When in doubt, consider having a certified appraiser or knowledgeable antique dealer provide you with a professional opinion.
