I LOVE this chair! I am 5'1" and always struggle with office chairs - the lumbar and neck support hit in the wrong places I always need a footrest etc. Not the case with this chair! Everything fits as it should from arm rests to lumbar support and the awesome adjustable neck rest. I loved it when I tried it in store and even more now that I've been using it about a week. Lots of adjustable features. It was very easy to assemble - I was able to do so myself in under an hour. Highly recommend!
I'm 6'1 225lbs and the chair is comfortable to me and has great back support. My only complaint is I with the head rest was higher it currently hits the top of my shoulders.
