The rubber backing keeps the rug in place when the child runs/plays on it.
We know that children are extra sensitive, but not to worry. This product has been tested and contains no substances, phthalates or chemicals that can harm your child's skin or health.
The pile of the rug dampens sound, creating a snug feeling, and is soft to walk on for all sizes of feet.
Playing hopscotch on one or two legs helps your child develop both motor and balance skills.
