Abstract: A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided in the preferred embodiment by a support system of independent poles, linked at their tops by a flexible strap or line. An impact anywhere on the fence causes the posts to flex inwardly, absorbing the force. Much of this impact injury is stored in system components and is subsequently returned, helping propel an errant jumper back onto to the rebounding surface. Numerous other embodiments and accessories are also detailed. Similar arrangements are suitable for use with above ground pools.

Abstract: An attachment for a circular trampoline includes four backstops that are attached to the base frame of the trampoline. Each backstop includes a backstop bed, which is attached to an arch-shaped backstop frame with a suspension system. Each backstop is mounted to the base frame and extends upwardly and outwardly from the base bed. An apex of each backstop is positioned over the base frame.
