I give it 3-Stars. It’s relatively comfortable but I can’t figure how to adjust the back and head support so I can stop over compensating while sitting at the desk and working; especially as I type. The wheels roll smoothly so that’s nice. The armrest padding is rather hard and I’ve scratched myself twice on the edge of it; plastic sharp and too hard. I wouldn’t recommend it because of lack of comfort and armrest too hard.
At 6ft tall / 190 lbs I find this chair really comfortable. I am really impressed with the headrest It is super comfortable. Also at the angle I use it (slightly leant back due to high monitors) it puts more weight on my hamstrings instead of my butt which makes it super comfortable. I agree with other reviews that it lacks more adjustment settings but for this price point I am really really happy. It feels like a much more expensive chair. Two of my screws were incorrectly color-coded (yellow instead of blue - according to instructions) but otherwise the installation was really fast and easy.
I LOVE it!!!!!!!!!!! Wish the mesh seat was just a hair tighter but it is a great chair. It comes up two inches higher off the floor than the other mesh chair with a head rest and that is why I got this one. Head rest is perfect for me and I am about 5’9”. I am 74 and had no difficulty assembling it.
I love this chair I have had no issues with my back since I got it. If I sat in my old chair for any length of time just standing up was pain full. It makes it easier to sit in a proper position with the supports where they help the most. I would definitely recommend this chair.
