There are a lot of pics showing what happens with bonded leather... It's scraps of leather that is basically glued onto a fabric. Really quickly this outer layer rubs off and once that starts it peels off even quicker. This leaves pieces all over the place and usually haven't had the item that long at all. Staples needs to remove and discontinue selling anything bonded leather. Beware this is definitely 100% a bad purchase.
This chair is very comfortable. There is a lot of back support and the arms being able to go up makes it very easy to get in and out of. The height adjustment is great. The only thing I am not completely satisfied with is there is no way to lock this chair in a leaning position.
