You know what is disgusting to think about? Putting your sweet angel of a baby onto a filthy changing table. While we wholeheartedly support all restaurants and facilities with changing tables (THANK YOU!!!), we felt there should be a barrier of protection between the table and your baby. That is why each pack of Dwypers contains a changing mat made of a poly-backed, waffle embossed product (think: dental bib). The poly-backing provides an extra layer of protection against fluids and other nastiness we don't even want to think about right now.
