This task chair is exactly what I was looking for. I have to fit my desk and chair into a very small space and was having trouble finding one with a small enough base. This one fit the bill perfectly.  The reason I gave it 4 stars rather than 5 is that the holes in the backrest and the frame didn't align properly so it was almost impossible to get the backrest screwed onto it; however, after some finagling, my husband managed to get it attached. Also, the stitching on the backside of the backrest looked a little tacky. But if you need a chair with a small base, I'd definitely recommend this one, as they're pretty hard to find.
