Can You Put a Trampoline on Artificial Turf?

This page is for families with a turf lawn, or about to install one, who want a backyard trampoline on it. Most answers online stop at "yes, use anchors." We read the anchor instructions from two makers and the site rules from three, and found the part they skip: the anchors are written for soft soil, and a turf lawn is not built on soft soil.

Can a trampoline go on artificial grass?

Yes, and the makers that address surfaces put turf in the acceptable group. Springfree's guidance says: "Yes, you can put a trampoline on artificial grass. It won't be as soft as natural grass but would likely serve as a better option than concrete since you can use anchors to secure the trampoline to the ground." JumpSport says the best surface is "dirt or grass," and only asks for dense foam under each leg on "a very hard surface such as concrete or asphalt."

A turf lawn sits between those two. It is level, which every maker requires, and it drains. But under the fibers is compacted crushed rock, not topsoil, and that changes two things: how anchors go in, and how the legs bear on the surface.

BERG's list is the one that seems to leave turf out for ordinary trampolines. Read it closely: its leg-trampoline ranking is about what you land on if you come off, not what holds the frame up. That is a fall surface question, and turf over compacted rock is a poor fall surface whatever sits on it. More on that below.

Why is anchoring a trampoline on turf harder than on grass?

Because the anchor has to pass through a layer built to resist it. A family turf lawn sits on 3 to 4 inches of compacted crushed rock, packed in lifts with a plate compactor; see base preparation. The JumpKing kit tells you the opposite condition is needed: "The ground should be soft, and it may be necessary to pre-soften this area with some water." You can soak compacted road base all day and it stays hard.

Springfree's anchor manual draws the line clearly. Item D: "Do not install this product on surfaces with sandy soil conditions. If you have rocky terrain or cannot install the pegs to their full depth, you must find an alternative method for securing your equipment." Item E repeats that the pegs must be installed "to their full depth." A compacted base is rocky terrain by design.

Below the rock is a second problem: if your native soil is sand, Springfree's anchor is not for it at all. Plan a concrete anchor point (below) instead.

None of the makers publishes a holding force, so we cannot say how many pounds that costs. JumpSport's own caution covers it: "even anchored trampolines can become airborne or damaged. Consult a qualified contractor to determine what type of anchor works best in your location."

How do you anchor a trampoline on an existing turf lawn?

Drill through the base, then screw the anchor into the soil beneath. This is our method; it follows the cutting practice in cutting around obstacles.

1. Call 811 and find the sprinkler lines. Springfree item C and the JumpKing kit both require checking for buried utilities, and JumpKing names sprinklers. If the lawn had an irrigation system, see sprinklers and artificial turf for where capped pipe may still run.
2. Mark each anchor point where the kit says. JumpKing: the midpoint of each leg, about 6 inches outside the leg base. Springfree: evenly spaced, opposite sides or all sides, 8 on the S155 and O200.
3. Part the fibers and open the backing with a small cut between stitch rows, just wide enough for the shaft.
4. Break through the base with a digging bar or a long masonry bit until you hit soil. Keep the hole narrow so the surrounding rock stays locked.
5. Screw the anchor to full depth. The eye should sit at the fiber tips, not proud of them; Springfree warns that a peg left high is a trip and toe hazard.
6. Pack the hole around the shaft with base fines, tamp with the bar, then brush the fibers back over the cut.
7. Mark the anchors. Springfree suggests it, in case long grass or landscaping hides them; on turf, a photo with measurements does the job.

Springfree also says to inspect the anchors periodically "because soil conditions may change over time." On turf, check that the eye has not lifted after heavy rain.

How do you anchor a trampoline on a new turf install?

Set the anchor points before the base, the same order we use for an in-ground basketball hoop on turf. This is the "alternative method" route Springfree leaves to the owner, and it is the only clean answer on sandy or rocky soil.

At each anchor location, dig into the subgrade, pour a small footing with an eye bolt cast in, and finish it level with the top of the planned base. The base is compacted around it, the turf is slit over the eye, and the trampoline ties down with straps. We do not give a footing size: no maker we read publishes one, and JumpSport sends you to a contractor for it.

Fix the trampoline's position before the turf goes down. Moving it later means new anchor points, and every abandoned one is a slit in the backing.

Do you need a pad under the trampoline on turf?

Under the legs, we recommend one. JumpSport only requires dense foam under each leg on concrete or asphalt, and turf is softer than that. But a steel leg standing on turf for months presses the fibers beneath it flat, and every landing pushes it down again. A strip of dense rubber or foam under each leg spreads the load and takes the wear instead of the turf. Pick a material that drains or is narrow enough not to trap water.

The bigger pad question is the ground around the trampoline. Our playground turf guide explains why lawn turf over compacted base is close to packed earth for a fall. A trampoline's enclosure net is the first defense; the surface beyond it is the second. BERG's point that artificial grass "combined with an impact-absorbing base layer" increases safety is the honest version of the claim: it is the pad, not the turf. If you want that protection, size the pad as you would for a play set; see fall height and shock pads and the pad types in shock pads.

How much space does a trampoline need on turf?

More than the frame. Springfree says keep the trampoline at least 3 to 5 feet from surrounding objects. JumpSport asks for a minimum of 24 feet of clear space overhead, free of wires and tree limbs, and clear space on all sides.

JumpSport also says to remove any obstructions from beneath the trampoline: on turf, leaves and toys. Clear them when you brush.

How do you stop a trampoline wearing out turf?

Move it a little, regularly. The fibers under each leg and in the path to the ladder take all the load and get pressed flat; matted fibers covers how to bring them back, and when they will not come back.

Our rule is to shift the trampoline a foot or two each time you cross-brush the traffic lanes, which is monthly for a family yard in our brushing and grooming schedule. JumpSport's method works on turf: two people lift one side by a rail section, keep it horizontal, rotate that end about five feet, then do the other end. It also says to disassemble the trampoline "for any move greater than a few feet." Dragging it across turf pulls fibers and can catch a seam.

If the trampoline is anchored, moving it means releasing the straps and re-anchoring, which is why fixed anchor points suit a trampoline that stays put. In that case, pads under the legs do the work moving would have done. Brush the leg spots against the grain whenever you move it or lift the pads.

On brand new turf, wait at least 24 hours after seaming before setting up a trampoline; see how long before you can walk on new turf.

When does this answer stop applying?

In-ground and flat-ground trampolines are a different build: a pit dug into the yard with its own drainage, which BERG rates artificial grass highly around. Turf laid over concrete or a roof deck has nothing to anchor into; Springfree's answer for concrete is sandbags, and our turf on concrete guide covers that surface. In a storm forecast, no anchor is the plan: JumpSport says to move the trampoline to a sheltered location or disassemble it, and Springfree suggests lowering the enclosure, moving it or taking it down. And the brand matters: Springfree's anchor is "only for use on Springfree trampolines," so for any other frame use that maker's kit and its own instructions.

Frequently asked questions

Will a trampoline kill artificial grass like it kills real grass?

No. Artificial grass needs no sun or water, so the shaded area under the mat stays green. The damage on turf is mechanical instead: flattened fibers under the legs and along the ladder path, and debris that collects under the mat. Pads under the legs and a monthly brush handle both.

Can I use sandbags instead of anchors on turf?

Springfree suggests sandbags for concrete, where anchors cannot go, which matches the CPSC's advice for soccer goals on artificial turf. On turf they are a fallback if anchors cannot reach full depth, but none of the sources we read gives a sandbag weight for a trampoline, so we cannot say how much is enough. A sandbag left in one spot for weeks also flattens the fibers under it.

How many anchors does a trampoline on turf need?

Follow the maker. Springfree recommends 8 on its S155 and O200 models, spread on opposite sides or all around; the JumpKing kit uses 4, one per leg. On turf, the number matters less than whether each one reached full depth, because a short anchor in rock holds less than the kit was designed for.

Will the trampoline legs rust on artificial turf?

Turf drains faster than a soil lawn, so standing water under a leg is less likely. JumpSport's inspection checklist still lists rust, with the fix "clean and paint." A pad that holds water against the foot of a leg is the risk to watch, so use a draining pad or lift it to check the steel during your monthly brush.
