I want to buy some foam tiles to use at my mom's house on her tile and out in the yard on the patio, but am having trouble finding something that seems "safe." I know everything out there is potentially "dangerous" for our health so I'm wondering if it's even worth making a big deal out of, especially since he won't be using it every day. It just causes me some concern that EVA foam mats were banned in Europe and not here..... Thanks for any advice/product recommendations mamas!
