I am just wondering when these foam/plastic type mats that your talking about became so popular.

My eldest is almost 13 (makes me feel so old) and he played on a quilt and lambs wool rug. So I'm just curious I guess. Then we had dd 6 and I just did the same thing, I guess the mats are a new phenominon or I was shopping with my eyes shut. Which is so me, shopping with my eyes shut I mean.
My bff has them in her play room for her toddlers so I'll let her know. Thanks for this thread.
