ABSTRACT:
Springs (10) or other elastic connectors used to support a bed (14) within the frame of a trampoline or the like are attached using methods that systematically vary the tension (or the travel distance required to reach limit of elasticity) between adjacent (or sets of adjacent) springs (10). These spring attachment methods increase the time it takes a given trampoline to absorb a given amount of energy, increasing the shock absorption time and thereby reducing the likelihood of an injury.
