A trampoline system has a rebounding bed and a resilient member located below the bed at such a position that the bed depresses the resilient member when the bed is sufficiently depressed by a person jumping on the bed. The presence of the resilient member makes it easy tune the system to adjust the performance of the trampoline and to minimize impacts on a jumper and thereby reduce the likelihood of bed-impact injuries.
