Trampoline Net Inside or Outside the Springs? The Answer That Decides the Whole Purchase

Why the position matters more than the mesh

Fall injuries on a trampoline are not mostly falls to the ground. The American Academy of Pediatrics has been consistent for years that most trampoline injuries happen on the mat, and the hazards at the perimeter are the springs and the frame. A net that sits outside the springs lets a jumper reach them: run at the mesh, and your feet and shins travel across the pad on the way. A net attached to the mat at the spring line removes that travel completely. There is nothing to land on between mat and mesh because there is no between.

This is why our trampolines rubric gives enclosure and edge design 30 percent, more than any other metric, and why the highest scores go to frames where the net is sewn or clipped to the mat: Zupapa sews net and mat together, Jumpflex clips its net to the mat for the full 360 degrees, Skywalker buttons the net to the jump surface at every spring, and Springfree deletes the springs altogether (best trampolines with an enclosure net).

The second-order effects follow the same logic. A net inside the springs means the enclosure poles sit outside the jumping area, so a jumper meets mesh rather than a padded tube. A net outside the springs usually means the poles are inside the pad line and clamped to the frame, which puts rigid steel at shoulder height. Pole padding helps; pole position helps more.

The three systems, and how to tell them apart

Our registry holds replacement nets for all three, and the scores follow the table: 9 for a mat-attached kit, 8 for a curved-pole net and 6 for an outside-mount net.

One nuance worth knowing before you shop: an outside-mount net is not the same thing as a net over the springs on a springless trampoline. Vuly's Ultra deliberately puts its coils outside the netting with net and springs arching in opposite directions, which achieves the mat-attached result by another route, and Springfree's rods sit under the mat where nothing can reach them (Springfree vs spring trampolines).

How to identify yours in 30 seconds

Stand on the trampoline and look at the bottom edge of the net. If the net ends at the mat, attached through button holes or clips to rings on the jumping surface, you have a mat-attached system and the springs are outside the net. If the net ends on top of the pad and you can see or feel the springs through the pad inside the net, you have an outside-mount system. If the net hangs from a hoop at the top of curved poles and tucks between the mat and the frame, you have a top-ring system.

Then count the poles and check the shape, because that is what a replacement net is sold against: five curved poles and eight straight poles need different nets even on the same 15 ft frame. Skywalker goes further and lists exact model codes its 15 ft enclosure kit fits, so a replacement is a parts-lookup job rather than a guess. Measure the frame and count the V-rings on the mat before ordering anything (best trampoline replacement nets).

Nets that fit each system

Three nets for the three systems above, all for a 15 ft frame. Buy for the system you have, not for the one you wish you had.

Can you move a net inside the springs?

Usually not, and it is not worth improvising. A mat-attached net needs V-rings on the jumping mat and poles positioned for a net that runs inside the spring line; an outside-mount frame has neither. Tying an inside-style net to a frame it was not designed for leaves gaps at the base, which is the exact failure the design is supposed to prevent.

If your enclosure is an outside-mount system and the net has reached the end of its life, you have two honest options: replace like for like and keep the pad in good condition so the covered springs are as protected as they can be, or replace the trampoline with a frame built around a mat-attached net. The pad is doing real work in that first option, so it is worth replacing at the same time (best trampoline safety pads, when to replace a trampoline mat and net). And whichever you choose, CPSC's wider guidance still applies: one jumper, no somersaults, adult supervision, and the enclosure intact (trampoline safety rules).
