It is a good quality chair and it has good ergonomics. It was easy to assemble. The headrest adjustments are kind of poor and may not work for many taller than 5'10''.
Don't bother installing headrest as it is way too low for an adult. Found a website hack that tells you how to install it several inches higher up. Not recommended by manufacturer but it makes the chair into a five star
The concept of mesh is nice with the nice headrest. The lumber support piece broke off very soon and not it hurts/pokes in your back. I believe the build quality of that particular piece is not good. I would not recommend for long seating for 4/5 hours Would not buy again
The chair is overall of good quality and comfort! I do wish the headrest was adjustable. I am 6’ 2” and I have to use the chair without the headrest because it doesn’t hit me in the right spot.
For the money this chair is great! First I purchased one for my wife and she loved it so after sitting in her chair and reading the reviews I purchased one for myself. I am in my chair about 4 hours per day and its comfortable and functional.
