Model 250 uses padded petals to fully cover the elastic cords. From black EnduroLast 2 elastic cords to a black frame, this sleek unit is designed to outlast and out-perform any steel coil spring rebounder. EnduroLast offers a smooth, cushioned, exhilarating bounce that helps you feel buoyant and happy! Now you can experience a wonderful stress-free bounce instead of the harsh, stress-full bounce your body feels on a steel coil spring rebounder. Our patent-pending, arched legs provide an exceptionally stable and safe platform, compared to straight-leg rebounders. This allows for a wider variety of exercises (as seen on our fitness DVD). The virtually silent bounce allows you to use this anytime, day or night. Have fun bouncing beyond your fitness goals, with the JumpSport® Fitness Trampoline!
