Springfree Trampoline is the world's first Smart Trampoline™. We've effectively removed the impact areas that cause injuries on a traditional, spring-based trampoline. KEY SAFETY FEATURES >> Mat Rods: Springfree Trampoline's flexible composite rods lie beneath the jumping surface and out of harm's way. Spring-based trampolines have springs that will pinch or injure a jumper. >> Hidden Frame: Springfree Trampoline’s frame is well beneath the jumping surface - you can’t hit it, period. The frame on a spring-based trampoline is a hazard to jumpers, resulting in significant fractures, lacerations and head injuries. >> SoftEdge™ Mat: Springfree Trampoline's SoftEdge mat is over 30 times more shock-absorbent than the pads. The pads on spring-based trampolines do not protect from injury, lose much of their shock-absorbency after the first impact and have the shortest lifespan of any part on the trampoline. >> FlexiNet™ Enclosure: Springfree Trampoline's FlexiNet enclosure uses flexible net rods to cushion jumpers and prevent falls. Spring-based trampoline enclosures use steel poles to fasten the net to the trampoline, allowing jumpers to collide with a solid pole and be dropped down onto the frame and springs.
