Our mats are designed for your rapidly growing baby to use until they are potty trained (approx. on or before they reach 2 years old). Its great surface area of 70cm x 55cm makes this possible, it is also intended to keep those wiggly hands and feet on the clean white surface when in use, unlike other mats which have a small and narrow surface area.Use it wherever your want, on public toilet changing stations, on the grass, on the floor, on the carpet, etc.
