I recommend for certain people highly this chair. First off want to say the chair is NOT for tall folks. It was bought for my wife and she is not tall so all works well. My 5'5" son liked it and takes it from her office any second he can. I'm just 6 feet and its not good for me cause my lower neck is above the head rest. Also the lumbar doesn't adjust high enough for taller people. I'm also at the upper weight limit and wonder how long it would last under my load. The ergonomic chair I used cost me $800 over 10 years ago so for the money given its features this chair is good deal. I really like you get 7 year limited warranty from Staples on the chair. To me this says its quality construction because I figure Staples will lose their shirt giving warranties that long if they had someone make them poorly made chairs.
I bought this chair to alleviate my back issues for working from home: while it didn't fix it completely I didn't expect surgery I felt a big improvement to my back support. Easy to put together god bless whoever decided to color and label the screws for easy matching the only minor drawback is the mesh feeling a bit plastic-y. Otherwise 5 stars as it's a sweet spot price/performance
