This review is for the Ergonomic Executive Office chair. I bought it because its white, and its a midsized chair. I am 51 and 130lbs and it fits my seat. It is a little taller where my feet doesnt touch the ground but that doesnt bother me because I sit cross legged anyways. The chair does feel sturdy. The silver arm rest is plastic. Ive had it for a couple of weeks, and it seems to be holding great and rolling great.
