There is no way this chair cannot be adjusted for your personal needs. Enormous range of adjustments makes that possible. Seat and back fabric is of high quality and pleasing to the eye. Putting the chair together was a little tricky, since some of the chair bolts were under a lever which was hard to reach with the included wrenches. No big deal.[...]
I work from home & might be in the chair 10+ hours each day. Being "frugal" (some would say "cheap") I have in the past gone with the very low end task chair. These often have lots of adjustments & ok back support, so they start out comfortable but there is not enough padding in the seat & soon I am sitting "sidesaddle" or sliding around on a supplemental seat cushion. Have had this chair only a couple of weeks but so far very happy I finally sprung for a better product. Everything adjusts, including height & angle of arms so it prevents the sideways slouch. If there is one thing they could change (and it is a very small thing) it would be to let the lowest height of the seat go another ½ to 1 inch lower. It slides under my desk but will not go under my keyboard tray.
