The didactic therapy and play set is modelled on well-known sports balls such as tennis balls, rugby balls, football balls, basketball balls, golf balls and baseball balls, and its velvety surface encourages children to try out their tactile senses and reduce stress. The kneadable natural rubber foam bounces slightly on impact. Especially for toddlers aged 1-6, hours can be spent playing with the motor activity balls, learning about their sense of touch and motor skills in a playful way. Due to their nature, the motor activity balls can also be used for therapy purposes, relaxation and stress reduction. Thanks to the flocked surface, the balls are comfortable to hold.
