cords are better than springs. there, i said it. trampolines that have elastic cords instead of springs are a better investment for your body, plain and simple. although springs may be one of the first things to come to mind when you think of a trampoline, they do not offer the best bounce. thick, metal, springs are unnecessarily strong for a mat that is 32 inches in diameter. as a result, springs can pull the mat so tight that it takes away from the low impact nature of the trampoline.
cords have the elasticity needed to give you all the low impact goodness of bounce. think about it scientifically for a moment; one of the many benefits of bounce is that the actual rebound the trampoline provides throughout your workout is allowing your body to work against gravity to build strength and endurance. depending on the height and speed of your bounce, your g-force - or perception of weight, can be up to four times your actual weight. if you're jumping on the ground or another hard surface, such as a trampoline with springs, your joints are responsible for absorbing the energy and force with which you come down.
trampolines with cords have the perfect amount of give while you bounce; they allow the mat to absorb your weight, offering a smooth and supported landing every time your feet hit the mat. like all good things, elastic cords can wear down over time. that's why our trampoline uses EnduroLast™ cords created by JumpSport. with a higher elasticity and thickness, they have a significantly longer lifespan than other cords on the market. additionally, they have a third and fourth knot with more adjustable settings, allowing users to get more use out of each individual cord on their trampoline. EnduroLast™ cords are designed for optimal durability and performance to provide a longer lasting, smooth, and luxurious bounce.
