Nap Mat Cupcake. Thereâs no better way to be sent off into sleepy town than on a Stephen Joseph Nap Mat. The fun designs will set your toddlers imagination going for dreams full of adventures and theyâll wake up happy and refreshed. Each design features a character pillow to sink their tired little heads onto, and an incredibly soft blanket to keep then snug and cosy. And when itâs time to wake up and play again, the mat rolls up tightly for easy storage.
