If you are in the market for a professional trampoline for some serious acrobatics, then the new Air King rectangular range is just what you are looking for. Thanks to the rectangular design, these trampolines give the highest bounce curve in the whole of the Air King range, & they are able to achieve this with a relatively smaller amount of springs. The safety enclosure can be woven into the edge of the mat at the base to provide additional security (i.e. there are no potential gaps which a small child could get through), & is fitted with zip fastenings for easy & secure closure.
