This rug is really just mediocre. I was totally expecting it to be thin, and it is. I figured this was ok because I wanted to use it in our playroom to protect the light colored carpet. The problem is that the backing has absolutely no depth or grip, so basically it's as if I spread a thick blanket on the floor. And you know how blankets behave on a floor--they never stay flat. The rug bunches up as soon as a child sits on it, runs across it, etc. So, I'm constantly trying to pull it and flatten it back out, and that's pretty much a losing battle. For us this rug is a fail. Maybe if it was on a hard surface and had a rug pad underneath it would do better, but I'm not sure.
