I had them too .... When my youngest was an infant I used it cause we had ceramic tile in our kitchen and great room and when he was learning to sit up I was always afraid he was going to fall back and crack his head open and the same when he was starting to climb on the couch he fell off so many times I was thankful for the foam mats I also used them in the daycare on the carpet so the kids had I firm place to do a puzzle but everytime it was walked on it would break apart .... Now all the pieces are in storage.
