Frequently Asked Questions

  • Does it have a cover?

    Yes. It has a nice cover with zipper.

  • What is wonder gel?

    It is a solid gel that is the shape of squares. The gel and the squares are a couple of inches thick, so that when you sit on them, they absorb your weight.

  • Do the holes go all the way through? I want to use it on my hard plastic shower bench without the cover.

    No, the holes do not go all the way through. So, staying wet might be an issue, although I'm guessing you could figure out how to easily dry it off. The only thing I'd be concerned about is cleaning it. The cover is meant to help get around cleaning issues, and I think you could easily mop it off when the cover is off, but I'm not sure what any heavy duty cleaning solutions would do it, like the solutions we tend to use in the shower. I think that's the only thing I'd beware of when using in the shower.
