Bests & Worsts Reviews from Amazon

Great product that works as advertised - once you get it to uncurl and lie flat on the floor. Taking a cue from a review of a similar product, I soaked the entire (very tightly curled) product in a sink full of HOT water (the hottest I could get out of the sink), making sure the entire thing was covered by water. After about 5 minutes of soaking, I pulled it out - and it was extremely soft and flexible. I dried off most of the water and then laid the product on a towel on the floor, laid another towel on top of it - and then covered the length of the entire product with stacks of books to ensure it got fully flattened out. An hour or so later, I uncovered everything - and it was totally flat (and firm) once again. A little bit of a hassle - but it works like a charm to make it flat as a pancake.
