The chair is way too small. I’m 5’11 and the neck rest doesn’t even reach my neck. The seat is big enough only for half of my thighs with the rest of my legs hanging off. The chair is too narrow and I’m only 190lbs. I can’t imagine anyone my size or bigger could fit in this chair comfortably. I gave it to my 13 year old daughter and it seems to fit her just right.
The arms are different than what is in the manual. They do not turn in or slide forward. They can be adjusted up and down and for my size they fit fine without further adjusting.
I had to remove the headrest because it couldn't be adjusted high enough. I'm 6' 1" tall. For a shorter person the headrest should be fine. It hit me in between my shoulder blades. The mesh is cold so I would prefer fabric. On the positive side I could adjust the armrests to fit and the chair high enough.
