The simple and intelligent design of the Spida inspires children to climb, stretch, imagine, and play with the varied entry points, graduated challenge and the many levels of play. There are different ways to use the Spida, the side bars offer an option of entry and egress, and the responsive ropes offer variation and challenge for the more experienced climbers, these are important aspects of play that support cognitive skills such as decision making and self regulation, as well as physical skills in agility, balance, and coordination. Opportunities to jump to the ground from the lower surfaces also help to build bone density, essential for physical health.
