With 5 star Jumping comfort & 5 stars for quality, the BERG Elite 14ft Green In-Ground Trampoline Incl. Safety Net is finally here! Extra long twinsprings which have extra coils give the user the ultimate bounce-experience. This unique feature to BERG enhances the energy of the users to produce more bounce than regular sized springs. The Twinspring system also allows for 30% more springs than that of a standard trampoline of the same size – more springs means more bounce! To increase safety, BERG boast their extra large spring padding on the Elite series which measures 30mm in thickness for extra protection if your child comes into contact with the spring area. The spring padding also covers more spring area than any other BERG trampoline being 400mm in depth, preventing trapped hands/legs in the springs. Rust-prevention technology is significant to extending the life of your trampoline frame. BERG have developed a 2-layer protective coat consisting of the steel frame & a zinc layer which provides serious protection against rusting of the frame – extending its lifespan & preventing weakening of the frame. A unique top cap with a screw cap ensures that the net & the frame are firmly connected, securing the enclosure of the trampoline & maximising safety for you child. Arched enclosure poles also make the bouncing area larger to other models, giving your children more room to bounce about & have fun! In terms of the base structure, unique, patented T-sections exclusive to BERG, bolt in place to secure the frame & maximise sturdiness
