The little girl I sent off to JK last year had to purchase her own mat to leave at daycare. They were directed to All About Kids to get them.

For those that use the mats do you find a difference between the fold up ones and the non fold. I can imagine certain size kids not being comfortable on the fold up ones depending on what body parts fall where and wonder if by the time I fold and store 5 mats if it would save me any space compared to stacking 5 nonfolding ones.
