this chair is super comfy and not too big. My 9 year old and I fight over who gets to use it. It also is a really nice shade of grey. My only advice would be if they are offering assembly maybe consider taking them up on it. It wasn't hard to assemble but a little awkward. Either way the sale I got it with made this chair a steal and it' very sturdy and comfortable.
I've had this chair for roughly 4 months very comfortable BUT the piston has already failed. Chair will just fall within minutes of adjusting the height.
