I bought this chair based on other positive reviews and was disappointed. The quality of the build is great, the chair has quite a lot of adjustments for the price. However, there are notable issues with it:
1. The arm rests are not coming up high enough for me. This means that I can lean on one arm rest or another, but not both. In either case, I have to tilt to the right or left. I need to rely on arm rests not to put too much pressure on my wrists as I type.
2. The arm rests have a groove for your elbows. If they were rotatable, this would have been fine, but they point straight, which is not the direction of arms of a person at a desk. This creates an uncomfortable feeling in elbows. If they could rotate, or at least did not have a groove, it would have been better
3. The back does not have a lumbar support to talk of. The back of the seat is a wrong shape for me I have a dislocated lower back disk, but this chair is tending to bend me forward, I seem to be fighting this position all the time
4. The seat is slippery for me - my butt tends to slide forward and I end up putting all pressure on the tail bone.
Overall the quality of the chair is great, it looks good, works well, only of shapes of some components were more fitting to my body! I can see that this chair could be great for other people, but unfortunately have to return it and spend more money and time to find an alternative.
