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.
The chair is fairly sturdy and well made compared to others in the price range I've tried. Solid lumbar support and comfortable if you sit properly but the bottom seat rails are narrow for anyone with above average thigh size. Cyclists / gym rats be aware! It appears well enough construction wise and the red color isn't bad considering it's red. I have some long term durability questions but it's cheap enough I won't be too angry if I get 18mo out of it.
Fits me really well. Was nervous buying it sight unseen but could pass up the price of a full mesh chair. Seems construction is about what I would expect for this price. Very comfortable and fits my 5'9'' 140lb frame very well.
I mostly like this chair it's definitely great for the price. I wish the seat had a little more depth or adjustable depth and that the headrest was easier to raise and have more height. The lumbar support could also be a little bigger as I definitely feel pressure from it a little closer than if it were spread a little taller.
