Hilltops offer high play value and ample opportunity to develop and stimulate children’s gross motor skills, social skills and creativity. Five Hilltops of varying heights encourage children to jump from top to top, helping to develop the ability to estimate distances, while building a familiarity with heights. The Hilltops’ stable design makes them perfectly safe for jumping activities, and the other included games suggestions. Each Hilltop has a non-slip rubber rim, which also protects indoor surfaces. Each set includes 5 Hilltops in three heights: two measuring 14.96" x 14.56" x 3.35"; two measuring 16.14" x 16.14" x 6.69"; one measuring 16.92" x 16.92" x 10.23".
