Our patented Variable-Bounce™ technology is an elegantly simple innovation that helps optimize the shock absorption rate and the bounce performance of the trampoline.

The upper, Primary Spring locks the PowerArm™ into the V-ring, while the lower, PowerSpring™ attaches to one of the PowerArm’s three stages--the top, middle, or bottom setting.
