Springfree Trampolines are a next generation design trampoline removing all dangerous design elements present in traditional trampolines. Springfree's springless trampolines use flexible fiberglass rods to give a soft non-jarring bounce. The rods lie beneath the jumping surface out of harms way. Springfree Trampoline's frame is well beneath the jumping surface. You can't hit it, period. The Springfree Trampoline FlexiNet enclosure has flexible supports to cushion jumpers and prevent falls. The jumper is directed back to the center of the mat and cannot make contact with the enclosure rods. If you are in the Maryland or Virginia area visit your nearest Play N' Learn to test bounce on a Springfree trampoline.
