What the headrest might seam a little which is not exactly a stable impression and is attached only behind the backrest. A height adjustment is not possible. Furthermore, the adjustment of the headrest itself is very minimal. So in my opinion, I could buy myself even the office chair without headrest would also have been a lot cheaper. The armrests can be better adjusted. The scroll wheel makes it very difficult to move the backrest up or down.
But otherwise fully satisfied with the office chair.
