I've read the posts about using foam and then covering with black carpet. Looks great, but sounds like a lot of work.

I'm wondering if anyone has used the foam floor tiles that are used in workout rooms? These are pretty cheap and easy to work with. I've done a floor with them and the tiles join together and there's also edging pieces to finish the ends. It would be easy to glue these to a piece of OSB, but I'm wondering if it would be enough padding.

Thanks
