The Springfree trampoline's design includes the use of glass-reinforced plastic rods articulating below the jumping surface, as opposed to the radiating steel spring coils of a Nissen trampoline. The jumping surface is lowered around 450mm below the jumping surface of a traditional trampoline, and the base's rigidity is derived from a tubular ...
The trampoline bed is rectangular 4.28 by 2.14 metres (14 ft 1 in × 7 ft 0 in) in size fitted into the 5.05 by 2.91 metres (17 ft × 10 ft) frame [10] with around 110 steel springs (the actual number may vary by manufacturer). The bed is made of a strong fabric that can be woven from webbing, which is the most commonly used material.
Pike Jump – Again from a straight jump start, the legs are straight, held together and lifted parallel to the trampoline and the arms and body reach forwards towards the pointed toes. Straddle Jump – Similar to the pike jump except that the legs are spread sideways approximately 90° apart and the arms reach forward towards the pointed toes.
In a trampoline, the fabric is not elastic itself; the elasticity is provided by the springs which connect it to the frame. While the trampoline is an old invention which relied on crude and flawed designs, the modern trampoline was invented by George Nissen and Larry Griswold around 1934. [255] 1934 Acrostic (puzzle)

George Peter Nissen [1] (February 3, 1914 – April 7, 2010) was an American gymnast and inventor who developed the modern trampoline and made trampolining a worldwide sport and recreation. [ 2 ] Background
A pair of jumpers A mini-trampoline.. Rebound exercise (or “rebounding”) is a type of elastically leveraged low-impact exercise usually performed on a device known as a rebounder—sometimes called a "mini-trampoline" or "fitness trampoline"—which is directly descended from regular sports or athletic trampolines.
The apparatus originated as a 'free exercise' for men, very similar to the floor exercise of today. [1] Most competitive gymnastics floors are spring floors. They contain springs and/or a rubber foam and plywood combination, which make the floor bouncy, soften the impact of landings, and enable the gymnast to gain height when tumbling.
