I'm 5'8" 170-lbs with a normal height office desk and this chair is just right for comfortable access to t e keyboard tray and desktop. May be a little low for some. The posture it encourages is a big improvement for back comfort over conventional office desk chairs.

Pros: great value, relatively easy assembly, BUT  mainly very, very comfortable and accomodation for back discomfort from sitting
Cons: none-- for some folks this different posture may require a little acclimation to optimize back benefits
