Springs or other elastic connectors used to support a bed within the frame of a trampoline or the like are attached using methods that permit the adjustment and/or a systematic variation of the tension (or the travel distance required to reach limit of elasticity) between adjacent (or sets of adjacent) springs. These spring attachment methods adjust the energy absorption capacity of the tramnpoline bed, as well as 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.
