The quality of the bonded leather was better than I expected.  The mechanics of chair are good and the quality of the chair is excellent.  The assembly was easy and parts were easy to use.  The one arm did not match exactly for the screws but with a little muscle I was able to get the line up properly.  My wife likes it and I am very pleased with the chair.  The chair rolls or should I say glides over the tile floor.  The left arm does become loose from time to time however, and I have to retighten it.  Comfortable too!
