This is one of the most comfortable desk chairs I have ever owned! The seat is firm and mesh back hits me in all the right places. I am short (5'2") and most office chairs with arms are oversized. This one is perfect!
I like the chair. It's comfortable the assembly was a snap and the adjustments are easy. My one criticism is that the chair seat actually sits at a very slight angle--the front is a little down from the back and there isn't an adjustment for the seat angle.
The chair assembly was easy and quick. The chair is comfortable for 1-2 hours in the office. If you have to spend all day sitting at the computer a better chair may be for you.
