My butt doesn't dread my office chair anymore.
When I first got it I tried it on a hard wood chair in my kitchen.  I was disappointed because it seemed to squish all the way down.  I then brought it to work to use on my mesh office chair.  It took a little to get used to, but the more I used it, the better my butt felt.  Now my butt is back to being happy after a week of using it.  I'm about to buy the ultimate for my home mesh chair, and then decide which one I want at work.  Remember that if you are buying this, your butt is most likely hurting.  After a week of no pressure points, your butt comes back.
