I just finished putting it together; it probably took me half an hour or so. I like the firmness and support of the chair itself (which I'm sitting in as I type this), a significant improvement over my old office chair.

The quality of this chair is top notch and the assembly instructions were simple to follow. The chair is very supportive and the adjustable to adjust the seat makes it even better.

The chair itself is decently comfortable, and I was initially satisfied. The chair itself is for my son who is 6'1" and he loves how the chair fits him. The headrest and curves in the back of the chair are built for someone his height. The armrests also adjust which is a bonus.
