Herman Miller- Eames E24 Chair.
Iconic believed E24 design chair by Herman Millions. I can find no stamp mark or label sadly but resemblance is convincing. Spins beautifully and adjusts.
Obviously as you can see it has been a well loved and used piece of furniture.
Available as is so you can take it as far on the restoration journey as you wish or just sit relax and enjoy as it is.
