Short version: Good for your posture, but not as comfortable as I'd hoped.

This chair definitely has an "ergonomic" feel to it. The padding on the seat is much more firm than I typically like but it does feel like it will hold up for a while because of that and it's not uncomfortable, just stiff. The seat and arms are covered in the same mesh material used on the back so if porous material on your bear arms or back of your thighs is a problem, steer clear of this. The back of the chair does jut forward a bit more than I was expecting, it gives great support to your lower back, but if you slouch (at all), that's the only part of the chair back you will ever feel. This is a good work professional chair.
