Trampoline enclosures are by far the most important accessory for any 12ft trampoline. A trampoline can be fun for all the family, but can also be very dangerous if not used properly. Falling off a trampoline, or landing on the frame can both cause very serious injuries. The easiest way to avoid this is to buy a 12ft trampoline enclosure to go around it.
The trampoline enclosure is basically a netting which is pulled around vertical posts attached to the trampoline frame, which then prevents anybody falling off, landing on the frame, or other children throwing things onto the trampoline when it is in use.
