It's been several months since I got this chair and I can still say that this chair almost exactly meets my needs as a short person (5'3") with lower-back problems. It doesn't quite get low enough to be the correct height for me, but it is very close and using a small footrest helps.  The adjustable features give a lot of good ergonomic adjustments, but the controls are a little difficult and finicky to adjust.  Overall, I'm satisfied with the chair because its price was reasonable and the quality is otherwise as expected for this price. It's a pretty good option for an ergonomic office chair for someone on a tight budget.
