Hop ’N Pop^® is a sensory-based, large exercise mat that encourages active play for pediatric adaptive physical and occupational therapy programs. The activity fitness mat contains a brightly-colored, custom-sized sheet of close to 2,000 bubbles that snap and pop each time a child jumps, hops, dances, or plays on the mat, thus helping children discover the relationship between cause and effect. The mat’s top layer is made of a sturdy, washable, mesh fabric with vibrant graphic designs, while the bottom layer is a 1/4" thick, non-skid foam vinyl, which is heavy duty for extra stability and absorbing impact.
