A Game-Changer for Potty Training Tots! P-thingy is a car seat protector that has been crash-tested and approved for use with all Foonf and Fllo models. With a waterproof backing, it helps protect against spills and accidents, prevents gunk from making it's way into the deep crevices of your seat, and provides little extra padding for an extra comfy ride. Plus, it's machine washable and can be installed/removed in seconds!
