The stones mimic those in a river, with each side of the triangle varying in steepness and difficulty. The goal is to jump from stone to stone without touching the floor. Change their position to create more challenging paths for children. Each of the stones has rubber studs on the base, which prevent them from slipping and protect indoor floor areas. Includes three 14" x 3"H stones and three 10" x 2"H stones. Weight capacity 110 lbs.
