I bought a used office chair about 20 years ago. It looks like it was made in the 60s. The aluminum base is massive and we did have to change the wheels from those old tiny brass ones. It's green perforated leather, and in all this time, the leather shows no wear, rips, discoloration or anything. The padding is still comfortable. Our daughter also used it for haircutting, coloring and perms. We've bought newer chairs which broke after 5 years. This thing is amazing.
