Strong trampolines equal bigger, smoother bouncing for the whole family. Good thing our new Jumpflex® HERO™ 12 ft trampoline has an innovative dual ring frame, which makes this range of trampolines our strongest and most stable ever. These 12 ft trampolines are engineered using high-tensile steel that will never buckle or lose shape, achieved through a world leading zero-bolt, zero-weld approach.

This all means our HERO™ 12 ft trampolines can handle an incredible 250 kg load and a max individual user weight of 160 kg.
