Trampoline

A trampoline is a device consisting of a piece of taut, strong fabric stretched over a steel frame using many coiled springs. People bounce on trampolines for recreational and competitive purposes.
The fabric that users bounce on (commonly known as the bounce mat or trampoline bed) is not elastic itself.  The elasticity is provided by the springs that connect it to the frame, which store potential energy.
