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.
