This is a nice moderately priced chair. The lumbar support is good and so is the headrest. The seat is able to be positioned not only up and down but also tilting forward/backward. I’m 5’2” and find this comfortable. Good seat depth and width. The armrest are ok - the go up and down but are not padded.
This is literally better than 600++ Herman Miller Aeron and it comes with headset included. Good lumbar support only thing lacking is can no lock the angle during tilting back.
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.
