Unfortunately, UPPAbaby does use PFAS in their products.
PFAS, or Per- and polyfluoroalkyl substances, are harmful chemicals that bioaccumulate in the body (meaning they stay in the body for a long time). This is how they get the nickname “forever chemicals”. Science is still studying the negative health impacts of PFAS but evidence is showing that negative health impacts include including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression and cancer.
PFAS chemicals are often found in chemicals stroller manufacturers use to make them stain-resistant and water-resistant.
