In my opinion, the chair is comfortable and supports your back. All the functions work as advertised. It was easy to put together and the instructions were clear. My only complaint is that the unpadded arms are a bit rough on my forearms (but I knew they were not padded when I bought it). To summarize, in my opinion, this chair is a good, inexpensive task chair that met most if not all my basic requirements.
We waited too long to replace our old office chair. This chair was a wonderful purchase because of price but most importantly because it was easy to assemble and is extremely comfortable, with excellent back support!
