Hi. This chair is very roomy and spacious for your bottom. However there is no back support especially for your lumbar. You will need to purchase extra support some type of accessory to support your back. The other area of opportunity is the tilt of the seat of the chair. There is none although the description lists that there is a tilt. The back of the chair reclines and locks but the actual seat it leans forward which again is not good for the lumbar of your back. Also the chair sits low even when fully extended at its highest height so...that could be better as well. The fabric is itchy. For instance if you are sitting in the chair with shorts on the back of your legs will begin to itch because of the type of fabric. All in all it's a seat until your back starts to hurt from the unsupported lumbar. I plan to purchase another office chair to replace this one.
When I first received the chair I was thinking of returning it because it seemed so big. After I thought about it and put it together I realized this is the best chair ever. It's comfortable sturdy and not heavy or bulky. I love that everything on the chair is adjustable and I am able to work better at my computer since I have it. Love love love it and would recommend this chair to anyone who wants to have a nice roomy comfy and back support chair to sit in.
Seat is wider than I expected and is comfortable. Seems to be reasonably sturdy. I have only had it for a week so its ability to handle stress over time is still being tested. It has a nice set of adjustments and rolls pretty well even on berber carpet. For an under 350 dollar chair I think it is worth the price. The lumbar support was a plus.
I tried a few chairs and none worked for me. I'm heavy and have poor back health. This chair is wonderful. Wider than I need so I'm able to change positions easily. Want to buy a second but currently there are no more in stock.
