Very comfortable chair with ample room in the seat.  The adjustable lumbar support works and feels great.  I like the height of the chair, but the lowest height does not fit well below an under-desktop keyboard tray.  My wife had some issues with her feet touching the ground.  At the lowest setting the seat is 18-inches off the ground. 

The chair is very sturdy and feels solid.  Armrests are a good height and 25-inches apart, so my arms fit well.

I would buy this chair again if needed.
