Jumping never felt so good!

EnduroLast Elastic Cords deliver the smoothest, deepest, and most supportive low-impact bounce on the market. These are highly advanced bungee cords, uniquely formulated to stretch 2x resting length, compared to standard bungees that only stretch as little as 1.25x resting length. We use either 55 ft or 66 ft of elastic cord on every trampoline, whereas low-cost, similar-sized competitor trampolines may have only 15 ft of bungee. The extended elasticity, combined with the longer length of our EnduroLast Elastic Cords, reduces the stress on the bungee material so our cords last significantly longer than trampolines with lower quality, shorter bungees.
