The trampoline enclosure is sometimes also called a safety net or fun ring. It is a circular net that fits around the outside of the trampoline and prevents jumpers from falling off. The net serves as a wall between the jumping area and the rest of the outside. Most, if not all, trampoline enclosures are designed to be sturdy enough so that if a jumper bumps into it, the net will not fold or break.

There are two different kinds of trampoline enclosures. One kind has the netting on the inside of the trampoline padding. The other kind has the netting on the outside of the trampoline padding. Many injuries occur when the jumper falls onto the circular rail of the trampoline. The safety net that fits inside the trampoline padding prevents these kinds of injuries. Most circular rail injuries happen when the jumper is not aware of the safety rules about not jumping too close to the edge. When selecting a safety net, decide if the inner or outer netting is best.

When shopping for a trampoline enclosure, make sure that you are aware of the shape and size of the trampoline. It is important that the safety net you purchase for your trampoline is the best fit to ensure safety of jumpers.
