Roger this chair has too perfect of a pattern and I think it is vinyl. I was able to get a swatch from underneath, it buns (doesn't go out, dried like plastic but I could smell a little protein while it was burning. The back side looks like and feels like ultra suede or a very fine leather, but I think the top is a vinyl.
Is there a definitive method to know for sure weather it is vinyl or leather?
