I really like this floor mat; and so does my 9 1/2 month grandchild. She just started crawling recently; and she can move very easily on this mat. We have the mat under a play yard and it fits very well. I like that the mat is one piece; so it is easy to move, no putting together squares every time we want to move it. Believe me I did my research; and this is a winner because it is non-toxic and not too thick that a baby's face can go deep into the foam. It offers just the right amount of cushion. I am very pleased with this mat.
