The WORLD’S LARGEST RECTANGULAR TRAMPOLINE! What is so special about this trampoline other than its size? The frame: This has the most robust frame in the rectangular trampoline industry. Most other trampolines use a maximum of 1.5mm steel frames. The patented five-leg heavyweight stabilizer frame is 3mm thick and made of steel tubing which is fully galvanized and built to last. The thickness of the top rail adds durability and stability to make the JumpPRO™ one of the strongest and most stable trampolines available. The bounce: The shape and size of trampolines is similar to those used in high-level competitions such as the Olympics. If you want top performance and enough room to do your tricks as well as practice routines, then there is no better choice currently on the market. Our high specification jump bed combined with the 142 x 9 inch springs gives the user added height and a really soft bounce. The Springs: It is not just the trampoline spring count (142) or the length (9 inches) that provides it with the best bounce, but the resilience of the spring. The springs are completely galvanized to prevent rust and corrosion. The net: The specially designed net allows you to choose between two options for attaching to the trampoline. The traditional, sewn in method, where the net is attached to the jump mat with cord to ensure that fingers and toes can't access the springs providing additional safety making this method ideal for younger bouncers. The second method is to attach the net to the enclosure poles using the bungee cords provided. This opens the net out to give more space inside the trampoline and by not attaching it to the mat, allows the trampoline to be as bouncy as it possibly can be. This is ideal for older bouncers and those wanting to perform tricks. All of the above combined will give you an incredible trampoline which will last for many years.
