The AirFlow jumping mat allows 50% more AirFlow. This results in better jumping comfort and higher and more flexible jumping! Because the TwinSpring Gold springs are placed at an angle, they are extra long and supple without reducing the jumping surface. Extra safety due to the thick PVC protective edge. The Safety Net has a self-closing entrance with distinctive trim, thick foam around the poles and is of good quality. A safe solution! The structure of the trampoline and the net is very sturdy due to the construction and the steel clamps and assembly pieces. Extra long lifespan of the protective edge due to an upper and lower layer of PVC!
