Only issue is that the head rest is more of a Neck rest. I'm 5'10 (M) 176-180 Lbs The head rest doesn't go up or down much just the angle changes. still overall a great chair though. The seat is a bit aggressive in its curve at first buy it eventually stretches and settles down. Hopefully it doesn't breakdown we shall see.
My wife gave me this chair for xmas last year and I really like it. It is actually more comfortable than the Herman Miller chair I have a work which I would assume cost at least 3x the cost of this chair. I recently purchased a second chair for my wife and she loves it.
Nice support. Seat hurts a little. I like it but don’t love it. I also thought a headrest would be a great feature but not finding it super comfortable either
