I have one that my kids throw at each other and play on. It was a silly gift from a friend. It's a little strange to sit on!

I might like it if my dimples conform to the nobbies. Other than that - no thanks. No need to massage my butt that badly.

I have to admit it brings up visions of polka dotted butts!

Do they make vibrating versions?

The idea is to make it easier to sew/quilt...not distract you!
But the idea is intriguing.

I wonder if the nubs would be like Croc shoes and almost have a massaging effect. ??? I think the web site said it increases circulation, so it might be possible. I'm not sure how it would make you use core muscles though, it doesn't seem like it'd be round enough. Of course, I have been known to lose my balance on the exercise balls, so maybe this would be safer. tee hee

ROLFLMAO!!!!!

Yes years ago; think I got it thru a gym supply company.
I've since thrown it out.
I'd briefly borrowed one from a friend at a retreat to try it out; thought it was wonderful
Bought it, after sitting a longer period found it annoyingly uncomfortable. I am big bottomed too. The nubbiness got to me plus my bottom got too warm.
My friend doesn't use hers any more either - didn't ask her why.

Oh!! WOOOOO!!! LOL

No kidding- the cellulite does that enough!
