Stepping stones to better coordination, balance and fun. The River Stones are inspired by stepping stones in a river with each side of the triangle varying in steepness and difficulty. The purpose is to jump from stone to stone without touching the floor - you can vary the position of the stones to create more challenging paths for children. Each stone has a rubber rim on the base which prevent them from slipping, and also protect indoor floor areas. Provides challenging, active, imaginative fun. Builds children's confidence when jumping, judging distances, co-ordinating and balancing. Improved design of the original River Stones. River Stones can now be stacked so that they are practical to store. Maximum load 100 kg.
