Baby foam play mat / foam puzzle mat — child safety profile

High risk

Interlocking foam floor tiles and padded play mats used in nurseries, playrooms, and under baby gyms.

What is this product?

Interlocking foam floor tiles and padded play mats used in nurseries, playrooms, and under baby gyms. The most common material is EVA (ethylene-vinyl acetate) foam — lightweight, colorful, and cushioning. These products became the subject of a major European product safety action in 2013–2015 when formamide — a reproductive and developmental toxicant used as a foam blowing agent in EVA production — was found migrating from EVA foam mats into ambient air at levels of regulatory concern. The issue remains relevant in markets where reformulated products have not fully displaced legacy inventory.
