Can children's foam play mats release volatile chemicals?
Yes. A 2025 study screened 34 children's play mats and found 71 volatile substances, including formamide, toluene, and alpha-methylstyrene among higher-priority chemicals.
What is actually in it
Many children's play mats are made from foam materials such as EPE, XPE, PVC, or EVA. These materials can release volatile substances into indoor air.
Babies and toddlers spend time close to the mat surface, so this exposure can matter during floor play.
What the research says
A 2025 study in Ecotoxicol Environ Saf tested 34 children's play mats with non-targeted screening. Researchers found 71 volatile substances.
The study used a risk scoring method and highlighted 14 higher-priority substances, including alpha-methylstyrene, formamide, and toluene. It ranked volatile chemical safety in this order: EPE, XPE, PVC, then EVA.
For supervised floor time where padding is not needed, a cotton baby blanket is a simpler option than foam. It is not a fall-protection mat, so use it only where that tradeoff makes sense.
