Purchased this play mat for our 5 month old grand daughter in the hopes it would help with tummy time, and I am so glad I did!! She absolutely loves it. She hated tummy time, no matter what we did or used to help her, she would not participate. Found this in my Amazon search, read the reviews and decided I had nothing to lose so I purchased 2, one for us grandparents & one for the parents. The design is fantastic! The water & air filled mat is obviously very comfortable for her (she even layed her head on it as if she wanted to nap!), the art work & floating 'fishies' keep her entertained. I am very happy with this purchase! It's a little awkward to fill with water, but it was definitely worth it for me. It seems to be very durable, it's easily cleaned and as long as you fill it with the suggested water it should be void of any mold or smells.
