The simple and elegant Tetrahedron inspires movement and allows children to explore it's triangular shapes. Climbing the structure encourages stretching and agility, important for physical development in the early years. The responsive nets are designed to allow children to experience the effects of their movements on the structure, while also feeling the movements of others and encouraging social development as they become aware of others. The membrane in the middle offers a space to steady and also to rest, if needed. Children will enjoy the social side while playing with their friends in the open design. An element of fantasy play can be introduced as young children imagine they are climbing a ship mast or conquering a mountain!
