Excellent chair at a very respectable price. Comfortable and offers good support after sitting down all day. We have Herman Miller and Steelcase chairs in the office and despite those chairs still being better they are certainly not worth the difference in price. The only thing to watch out for is your height. I am 5'8" and the headrest is still a little too low for my liking bumping my top vertebrae when I sit up straight. However if you don't care for the headrest you can easily remove it.
Easy to assemble with an extra set of hands (can still do it alone just takes a bit more time). Came nicely packaged clear instructions. The chair itself is very comfortable and has a good amount of adjustability. I especially love the arm rest height adjustment. Hoping for good durability - if it lasts 2-3 years I'll be super happy with it! Used by someone with average build 5' 10"
