This chair was just what I was looking for at the right price! Be careful assembling it; particularly the arms and back. Slightly screw in the arm bolts before attaching the back. Then barely attach the first bolts in the back before putting in the last bolts. After that keep rotating with tightening bolts a little at a time until they’re all tightened down.
We got this chair for my son to do at-home schooling and homework at a small desk in his room. His plan also includes it as a comfy seat for gaming. It is much nicer than my own office chair the padding and arms keep him comfortable. The adjustability of height for his desk also helpful all of which might help with the focusing etc.
The chair was fine but a washer that was suppose to be casted into the plastic arm was missing. So that meant you couldn't tighten the bolt up that held the arm on. The arm holds the angle between the seat of the chair and the back of the chair so it's really important. I ended up sourcing a nut that fit together into the casting where the washer was missing and I drove it in with a hammer and a punch. This allowed me to tighten up both against the but holding the lower arm bolt in place and tight. Seems to be working for now.
