This product is a good buy very well constructed (not cheap at all). Only issue is I'm 6'2" but only 185 lbs and I find the seat a little tight and the back a little short. Your mileage may very.
I bought this chair to replace a very old one as I am at present working from home every day. It is very comfortable and I am able to work comfortably all day. (In my old chair my back would cramp up after a few hours.) It was very reasonably priced. I highly recommend this chair to anyone needing to work for long hours on a computer. The only improvement I can think of is that the neck rest could have a better height adjustment. I'm 6' tall and my shoulders brush the bottom of the neck rest when it is at it's maximum height. People taller than I am might have an issue with that.
I loved this chair. I love the material ease of build and also the quality. Nit pick (and doesn't sway me from buying again) is the arm rests dont move side to side or forward or back just height. Again not a deal breaker just if i had one thing to change.
I like a lot of lumbar support so I was hesitant to just buy a chair online sight unseen. But the other reviews were accurate and I'm so happy with my purchase.
