I wanted to really like the chair but the lumbar support shifts on me and whenever I lean back it moves. I have to adjust it all the time. The seat width is fine but the arms don't adjust much outwards more so it is a little tight to sit in. I am 5'11" 215lbs. My previous chair was wider and would go lower (height wise). I would of rated this higher if I didn't have to constantly adjust the lumbar support...
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.
