I LOVE this kneeling stool. Before the day was over my 3-week long backache was subsiding and by the next day it was gone. It has not returned since I have been using this chair/stool. I'm a believer! I'm not going back to a chair again & will keep this at my desk forever. I work on the computer all day long so this has fixed all sorts of back ache problems for me. what a lifesaver! The knee pads are plenty squishy too.
