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...
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.
The Hyken chair is fine but after sitting in it for about an hour I noticed that my sciatic nerve starting bothering me which it usually doesn't. The front of the chair hits the back of my legs in such a way that it causes a problem. The box was already gone in the garbage so we're left with a chair that no on in the house is using.
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.
