For context I bought this chair half-off so I'm reviewing it as a $130 chair. At that price I think it's a solid purchase. The build quality feels robust. I love the mesh which will be perfect as it gets warmer. As someone who is 5'8" the lumbar support and head rest fit me perfectly. I would like to see a greater degree of adjustability when it comes to the armrests and the angle of the back.
Assembly was a breeze. It's comfortable in the way that a good office chair should be--I could never fall asleep in it but my posture is better and my back doesn't hurt at the end of the work day.
I started off my search for an office chair looking at the $1000 x-chair which I have never sat in. at $149 (on sale) I can't imagine what could be any better than this. Great chair very comfortable for sitting 8+ hours a day. Seems to be well made and should last for years. Highly recommend!
