Device: Trampoline https://amzn.to/2UZ1Pmn 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. A mini-trampoline (also known as a rebounder, trampette, jogging trampoline, or exercise trampoline) is a type of trampoline less than 1 metre (3 ft 3 in) in diameter and about 30 centimetres (12 in) off the ground, often kept indoors and used as part of a physical fitness regime. So-called rebounding provides a form of exercise with a low impact on knees and joints. Mini-trampolines do not give a rebound as high as larger recreational or competitive trampolines.
