Abstract: The trampoline with inflated base includes a generally toroidal shaped inflatable tube having an open center area. A mesh rebound member extends over the open center area and is secured around its entire periphery to the tube on the upper surface of the tube member. The tube includes a singular air duct or a plurality of air ducts extending radially which allow communication of air between the space interior to the tube and the space exterior to the tube.

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.
