Overall the chair is just barely satisfactory. It's not terrible, but it's not really all that good either. The biggest issue that I have with this chair is the width of the arm rests. I am male 5'8" 150lbs, and while sitting in this chair, with the most narrow setting for the armrests, my arms are spread out like chicken wings because the armrests lay a few inches wider than a normal resting position. This is quite the shame because the armrests themselves are actually grooved to better fit your arms, but I just can't comfortably reach them. Having to type and mouse around on a computer for hours on end makes the armrests on this chair more of a nuisance than anything else.
I am satisfied with everything else; the rest of it is pretty standard fare. The cushioning and the backrest are just "okay". I was expecting a chair that would fit the grooves of your butt and back a little more, and even though you can lean back and recline a little bit (depending on how much you loosen or tighten the knob), it is still a bit on the stiff side.
In the end I would not recommend this chair to anyone unless you are around 5'11"-6ft tall-ish, or have a wider build. If I could still, I would return it, and save my money for something better.
