JumpSport Fitness Trampolines deliver the smoothest, deepest, and most supportive low-impact bounce on the market. Featuring EnduroLast Elastic Cords, uniquely formulated to stretch 2x resting length, compared to standard bungees that only stretch as little as 1.25x resting length. The 350 has a 32.5-inch jumping surface, arched legs, and 3 easy-to-adjust firmness settings. The JumpSport hinge is light but creates a super stable, rigid frame rail for confident and secure jumping. Work out without worry. Step up with confidence and add versatility to your fitness routine with the arched-legged trampolines and handlebar accessories. No-tip arched legs are safe and reliable, and allow you to stack multiple units in a commercial setting. The mat extension skirt and petal designs protect jumpers from stepping on the cords, and provide more exercise space, while the trampoline legs and 12.5 inches-high frame are stable enough for push-ups, dips, and more.
