Rated 1 out of 5 by MGinSB Didn't help at all!
I have to agree with other review...did not stay on my desk chair. Tried it on couch, car, dining room chair and other places..........did not help at all. Tried it with different amounts of air also.......nothing. Waste of shipping charges both ways!

Being a sufferer of chronic back discomfort I was looking forward to how this might relieve some of it. I understand about it helping to strengthen your core - my complaint is IT WON'T STAY ON MY OFFICE CHAIR! It constantly is sliding off and I have to constantly reposition it. I have an ergonomic chair with a cloth seat - but it constantly slides forward taking me with it which leads to almost falling off the chair. Definitely needs more 'grip' to stay put.
If i can just sit still in my living room chair - it does seem to work.
