To play, simply insert the large rubber piece on the platform and snap the 4 safe feet (each a vinyl-covered spring) on the bottom side. Great to develop balance and for sensory integration, as a stand-alone component or part of an obstacle course. For indoor and outdoor use. With a square surface, offers a larger jumping area than the classic round trampolines. 65 x 65 x 12 cm high. Maximum weight: 73 kg.
