If you have a standard trampoline & are looking to upgrade you will sure to see the difference when on this BERG in-ground Ultim Champion trampoline. Featuring Twin Spring Gold spring system you will definitely notice a substantial amount of different compared to a bounce on your standard trampoline. Upgrade to the best & feel the difference. Rectangular trampolines are possibly the best type of trampolines if you are not restricted on space. Spanning a larger length than the average trampoline, you are more likely to get more space & a better fit for your outdoor space. On a rectangular trampoline you can jump over the entire length, whether you want to roll, do a running handstand or simply run; the space & possibilities are endless. The jumps that you make on a rectangular trampoline are more controlled & you have more room to practice additional types of jumps without worrying about the room you have. The shape of the Ultim Champion trampoline ensures that the trampoline fits perfectly in a geometric garden design. Due to the trampoline’s size -11ft x 7ft- it can be installed in practically any convenient place if you have a larger outdoor space. The Champion series has incorporated the Air Flow technique to enable our little ones to make higher jumps. This jumping mat allows 50% more air permeation compared with a standard jumping mat. As with any trampoline good air flow ensures less resistance while jumping, which is why your little ones may be jumping higher than you would imagine. The durable air flow jump mat is made from woven polypropylene & contains special spring-eyes for the Twin Spring system. The loops for the strong metal spring eyes are thoroughly joined to the jumping mat with no less than 8 rows of stitching. The perfect jump area is that optimal part of the jump mat which results in the best jump experience. Jumping outside of this area results in a sense of feeling as if you are being pushed towards the inner part of the trampoline. Trampolines comprising of Twin Spring Gold Springs are mounted in the shape of a “V” – you will find only BERG offers this amount of quality on trampolines. This allows for larger perfect jump area compared to trampolines that are sold with a conventional spring. Due to the angled positioning of the Twin Spring Gold, the springs are longer in length without compromising the size of the jumping mat.
