Foamed floor mats are mainly made of high foamed polyethylene by chemical process, and some illegal manufacturers are really toxic.

This kind of foam mat is cheaper, because it is made of inferior toxic substances, which is harmful to human body and cannot be used by children. The products produced by general standard manufacturers are non-toxic and can be used by children.

Buy foam mats on professional and safe websites, not cheap ones. For the sake of children's health, please don't use inferior foam mats, foam puzzles, foam slippers, foam toys, etc.

Foam mats have been banned in Belgium and stopped in France on the grounds that they release the toxic substance formamide. Formamide easily penetrates into human body from human skin, damaging blood and nervous system. Because of its volatility, formamide can also enter the human body through the respiratory tract, which has cancer risk.
