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.
