Question: are foam play mats safe for babies?
Answer: Many foam materials like those used for baby mats, yoga mats and in gyms are usually made up of polyvinyl chloride (PVC), polyurethane, or EVA. ... Polyurethane, although itself is non-toxic, is flammable and typically contains added flame-retardants like PBDEs that can be detrimental to child development (2,3).
