The chair is utilitarian. I sit in it 6 hours a day and have no problems with comfort. At 6'2" the adjustable armrests are critical as is the lumbar support. My only knock is the headrest does not adjust forward and back only up and down.
This chair is really comfortable. Only thing is - it's too short for my desk! That's my own fault for not checking the measurements before ordering. My desk is 29" high & I'm having to sit on a cushion to make myself tall enough.
I'm 6 2 around 130lb. The chair is pretty comfortable and I like the head support. What I don't like is the tilt lock. It only locks at up straight location but not when tilted. Also I wish I could adjust the depth of back with the bolts in the bottom.
