I'm 5'7" 160 lbs. It fits me perfectly and feels really comfortable. However I give it 4 stars because the headrest needs to be more adjustable. I got this chair for the guy who works for me 6' 190 lbs. The headrest was pressing the back of his shoulder even after he pull it all the way up.
Great chair BUT assembly was a bear! Everything went fine until the last step - attaching the headrest to the seat back. The was a tolerance problem either with the chair back or the headrest; screen holes did not line up properly. If not for this the rating would be excellent.
