I love this rug. It's super cute. I got the largest size there is. Very colorful and my son uses the states as different animal cages for his toys and the kids love to look at the map and the letters. It's a very fun addition to our playroom that has hardwood floors. It does not require a non-slip rug pad underneath it. It stays in place without it. My only gripe is that it has frayed pretty easily compared to other rugs. Need to be careful when taking the plastic ties off and around pet cats.
