How does Springfree™ trampoline work?

Springfree™ Trampoline is rod-based, using strong flexible fibreglass rods instead if springs. Imagine a circle of fishing rods standing upright with their handles stuck firmly in the ground. If you bent them all in towards the center and connected the tops of them with a tight material, you would basically have a workable trampoline. If you landed on the edge you would spike yourself on the end of a rod—not a good thing. So instead of the rods standing upright, they have all been leaned over. They still have the ends bent towards the center, so they still keep the mat tight. But if you land on the end of a leaned over rod, you cannot spike yourself. Instead the end of the rod is just pushed down. This gives a relatively soft and safe edge to the mat.  more
