Sturdy and comfortable
Excellent choice for a sturdy and comfortable office chair.  The assembly was quick and simple; the instructions were clear and easy to follow, and all the hardware and tools were included and well-labeled.  The mesh backing is firm and comfortable, and the seat is soft and cushiony.  The height of the lumbar support is adjustable.  The arms can be rotated up to be out of the way; however the armrest height is not adjustable. (This was not an issue for me because they happen to sit at the perfect height for me.)  This chair is a definite improvement from my previous office chair.  Overall great chair - the only unfortunate thing is all the typos in the product listing.
