Active Kids Happy Kids: Great for safe, family fun our trampolines are a great way to get kids off those electronic devices and outside to burn off some of that energy. Kahuna trampolines are a great way to improve gross motor skills and coordination in younger children PLUS they're great for when family and friends with children visit. Springless design: Rather than using steel springs, this innovative design uses super-responsive, wide elastic straps all the way around the mat to provide the bounce in a safe springless jumping area. This is a heavy trampoline and uses linked legs and grounding straps for superior stability. The structure of the legs also minimises the tendency for legs to dig into the ground. Legs also feature re-enforced joint bars to enhance strength and stability. The padding cover of the trampoline is UV stabilised and has embedded nylon mesh for re-enforcement.
