I like the chair generally very much. The head rest seems unnecessary and we did not install. I really wish the arm rests could be swung away as they can be too restrictive at times.
Bought it couple of weeks ago. I just wish back lumbar piece would have better adjustment for the lower back. Head piece is also limited on adjustment. Overall I'm satisfied. I use it for about 8 hours daily and no back aches like I used to have with my prior chair.
