These things will make under trampoline cushioning and provide lovely landscape. But you can put some natural things like grass, rugs and many more for a certain period.

This article will guide you on ideal floor material for trampoline. Also, I’ll cover here under trampoline skirt ideas so kids and pets’ safety. So, let’s find out which trampoline floor material suits you best!

What to Put Under a Trampoline?

Here I’m going to discuss 13 different trampoline base materials that you can put on your trampoline for safe flooring. Let’s know, what is best to put under a trampoline.

What To Put Under A Trampoline

01. Trampoline on Grass Itself

As a first-timer, you may wonder, can I place my trampoline on the grass?  Yes, the grass is the most widely held natural thing to put beneath the trampoline. But choose a flat lawn for safety purposes.

It provides good aesthetics as well as great safety than setting the trampoline on bare ground, deck, brick patio, or concrete. But I’m not claiming that grass is the safest option as there are other cushioning base materials like rubber mats, artificial turfs, rubber mulches, barks, etc.


  • Almost zero cost
  • Easy setup


  • Grass needs extra care
  • Dirt may form on trampoline legs

02. Trampoline on Play Sand

Sand is another good option to use as trampoline floor material, especially when there is not enough grass around the trampoline. Adding sand to the trampoline floor will give you a desert landscape as well as some protection if kids fall off the trampoline.

But sand is not the safest option as there are some drawbacks. Sand can be tracked easily which is not safe during bouncing. Prolonged exposure to sand might cause lung damage in some cases. Also, animals could use sand as a bathroom.

If you want to add sand after purchasing, it costs around $5 per bag. For your information, one sandbag can cover 1/2 cubic feet area. So, for a 14 ft trampoline, you need almost 80 sandbags equal to $400 to fill the area with sand, that’s not too cheap, right?


  • Lasts longer
  • Easy to apply


  • Not very bouncy
  • Quite expensive

03. Trampoline on Dirt

The next place to put a trampoline in the garden is dirt. This is a natural way and not so cushioning as rubber mulch, mat, or turf. Due to being natural, it is a low-cost method.

Without grass, dirt may move with the air. In this case, you also have to move the trampoline to a new place having enough dirt.

If your yard has numerous trees and scrubs, the fallen leaves will also give you a good cushion, especially in the autumn. You can also pile up tree leaves for natural cushioning.

But dirt might be too hard when they get cold or dry. Falling off such a tough surface might be hazardous. So, you can use an extra soft layer there.


  • No cost base idea
  • Good cushion


  • Dirt or leaves may move with the air

04. Trampoline on Wood Chips

Wood chips or bark is an ideal cheap material to use on the trampoline floor. If you live in a wooded area this will add good aesthetics, just choose the right shade mulch.

Wood mulch also absorbs some shock that will add safety if jumpers drop to the ground. To get the best outcome, apply at least 12 inches of depth wood chips. Some playgrounds use bark to cover the base area.

Usually, one bag of wood mulch covers around 2 cubic feet, which costs almost $3 to $5. So, you can cover the 14 ft trampoline base area at $100 easily. But some wood mulch needs $150 and even more.

Keep in mind, that wood mulch might attract bugs and pests. There are also risks of breeding mold and bacteria in the ground.

  • Found everywhere


  • Not so bouncy as rubber
  • Risk of attracting insects

05. Trampoline on Rubber Mulch

If you want to ensure a soft and safe landing on the trampoline, I highly recommend you opt for rubber mulch. It provides great shock resistance. You might know, nowadays most playgrounds and football fields are filled with rubber mulch.

Rubber mulch lasts longer as it deteriorates slowly and prevents from mold forming. This soft and bouncy trampoline base material provides an ideal floor under the trampoline and borders. The rubber mulch comes in a dark color that seems to mimic the dark wood mulch.

Before putting soft rubber base for trampoline, you have to dig a circular hole at least 3 inches in depth and then apply the mulch there. But, wood or rubber mulch works best for 12 to 14 inches in depth. For further safety, increase the depth of the hole as well as extend the circle diameter.

But rubber mulch isn’t too cheap as wood mulch. You have to spend around $350 for each cubic foot to apply rubber mulch. For example, a 14-ft round trampoline needs 156 square feet which is equivalent to 43 cubic feet of mulch.

So, if anyone asks you, what is the best surface to put a trampoline on? Undoubtedly, you can recommend him/her to use rubber mulch as base material on the trampoline to get the best experience.

  • Long-lasting


  • Expensive
  • Digging necessary

Grass mat is also a long-lasting floor material. You can cover a 12 ft round trampolines base area below $350, that’s littleexpensive, but not too high as rubber mulch.

Some trampoline owners use rubber padding beneath the artificial turf; thus, they get the best result for the combo materials on the trampoline floor. To anchor the trampoline on artificial grass use anchor kits instead of sandbags.

If your trampoline base is grass growing, but you need extra protection in case of falling, these mats will suit well. They won’t damage the lawn. You can easily fold them for carrying and storage.

Gymnastics mats are a little pricy trampoline base idea than grass, bark, or sand. They are brightly colored that mightn’t stand out well with the existing beauty but provide cushioning enough.

Most of them aren’t designed to be used outdoor for long as they are prone to damage due to sunlight or harsh environmental elements. So, you can bring mats inside after each jumping session.

09. Bury the Trampoline

Burying the trampoline would be a crazy idea for those who look for a unique idea of what to put on your trampoline. The ground-level trampolines provide a great outlook as well as safety.

This needs digging a large hole, according to your trampoline and then putting the trampoline there. But it might be quite expensive for some homeowners due to hole preparation and retaining wall building but worth the money.

After installing the trampoline, the legs will go under the ground, thus providing a wonderful look to the backyard. You can add a side net for further safety.

There are some drawbacks too. If springs come off pets or kids can go under the trampoline easily and jumping in such a situation can injure the underneath kid or animal seriously.

Installing an in-ground trampoline is quite a hassle too. But, you can hire professionals to do the job without much trouble.

Now, the question arises, what to put under an in-ground trampoline? Well, you can place pea gravel or weed barrier under the sunken trampoline.

13. Trampoline on Pea Gravel

Pea gravel is another low-cost under trampoline landscaping idea. It is a natural way that’s why many homeowners already started using it in their playgrounds.

The little pea-size rocks provide better shock resistance than sand or grass. It can also drain water easily which is also a positive side. Moreover, it doesn’t attract insects like sand or bark thus the risk of mold and bacteria forming reduces greatly.

If you want to ensure a good cushion, put 12 inches or more depth pea gravel. But falling over gravel might cause injury. So, you can use soft padding to reduce the falling impact which will increase the cost.


  • Minimum cost
  • Low maintenance


  • Additional layer needed for cushion
  • Gravel impact might be dangerous

Under Trampoline Skirt Ideas

Is It Necessary to Close off the Area under Trampoline?

You might need to close off the border below the trampoline for several reasons including-

Kids and Pets’ Safety

Sometimes toddlers or your pet animals might go beneath the trampoline and if you jump in this situation it could injure them. But if it’s surrounded well, they can’t enter there.

Restrict Wild Animals

Another reason is wild animals might arrive under the trampoline and could damage it. So, by closing the skirt below the trampoline, you can easily limit wild beasts to enter there hence protecting the trampoline.

How to Close off the Area below a Trampoline?

You can block the border beneath the trampoline in different ways such as-

Build Wall

Build a wooden wall and surround the below space of the trampoline. Instead of wooden material, you can use concrete or plywood board. But consider the jumping effect and keep proper clearance.

Enclosure Net

An enclosure net is another great way to close off the trampoline under space, especially if you want to use the space for gardening, chicken coop, or other purposes.

Storage Box

You can store different items like piled wood under the trampolines. But keep enough clearance so jumpers don’t get direct impact while bouncing on the jumping bed.

Under Trampoline Safety Ideas

It’s important to make a safe trampoline base. That’s why you can do some things that will make under trampoline safe and cushioning.

  • Make flat the base as much as you can.
  • Remove sharp and hard elements from the base and surround the trampoline.
  • Install a full enclosure net to prevent falling to the ground.
  • You can surround the trampoline below the space to prevent entering kids, pets, or wild beasts.
