Springfree™ Trampoline offers you the World’s Safest Trampolines. After 14 years of injury prevention research, we bring you a smart, safety-conscious design from a team of world class engineers. Our Large Square Trampoline and Safety Enclosure is designed for jumpers of all ages. Our 3.4m wide x 4.1m diagonal mat jumping surface is equivalent to a traditional 4.3m trampoline but takes up the space of a traditional 3.4m trampoline. This is a large trampoline, with an equally large bounce., , Springfree™ Trampoline uses flexible fibreglass rods to give a soft non-jarring bounce. The rods lie beneath the jumping surface out of harms way. Traditional trampolines have springs that give a harsh, jolting bounce, and despite safety pads, can still injure., , Springfree™ Trampoline’s frame is well beneath the jumping surface. You can’t hit it, period. On traditional trampolines the frame is a hazard to jumpers, being the same height as the mat.
