Has anyone used the 2" thick folding Bollinger exercise mats? I need to put something down on my cement basement floor -- the bottoms of my feet are starting to hurt. I've read all the posts about the 2' interlocking tiles that many people seem to like, but I'm going to need to pick the mat up everyday after my workout. It seems this foldable mat would be a lot easier to pick up. But I'm wondering if it's too thick and cushy for jumping around on. Thanks for your input.
