Bouncing River Stone is designed as a complementary add-on to the original River Stones. It combines a soft base with a rigid top platform supported by three robust steel springs for a controlled, responsive bounce. Each step and jump requires subtle ankle and leg adjustments, building balance, stability, and proprioception. Use it on its own for focused motor-skill training or pair it with River Stones to create more dynamic play and obstacle-course setups. Perfect for sensory integration and proprioceptive training, this stone allows children to bounce and adjust their movements, supporting physical development and strength enhancement.
