This roba changing mat is particularly comfortable for your baby because the surface fabric, made of 35% cotton and 65% polyester, is coated with phthalate-free PU (polyurethane). This makes it not only skin-friendly and soft for your baby but also washable and therefore easy to care for. The underside is made of polyester. The soft padding inside is made of polyester fleece. With its three-sided raised edge, the changing mat gives your baby a sense of security.
