This chair has good lower back support but the seat is too short making it very uncomfortable for me. Unless you're a very small person you might want to stay away from it.
I have a home office and wanted a chair that I could sit in for much of the day. I really like how comfortable it is all the options to make it fit perfectly for me. Before this chair I had experienced back pain from my old chair. This one has virtually eliminated that pain. And assembling it was a breeze took about 30 minutes. I'd buy it again.
I really am happy with the chair. It was nicely priced and easy to assemble. The many adjustments make it easy to get to an ergonomic position. It looks reasonably ell made so it should last for awhile.
