Are you looking for the ultimate bouncing technology? With the BERG Elite 11ft Green In-Ground Trampoline Incl. Safety Net, you get BERG’s unique twinspring technology which features extra long springs & allows for 30% more springs to attach to the jumping mat. Both larger springs & higher quantity of springs means more bounce, so BERG have managed to combine both elements to produce a smooth & high quality bounce for the user. 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. In terms of the base structure, unique, patented T-sections exclusive to BERG, bolt in place to secure the frame & maximise sturdiness. The framework also comes with extra rust-protection which is provided through a 2-layer coat as a zinc layer protects the steel frame for rust prevention. The enclosure features a top cap with a screw top that secures the enclosure net with the enclosure poles, ensuring that your child is secure when bouncing in the trampoline. Curved enclosure poles increase the jumping area for the user when the trampoline is in use, maximising the available space.
