If you want a trampoline which won’t stand out in your backyard you can easily choose the in-ground model. As the name says, the in-ground trampoline is a special type of trampoline that installs into the ground, leaving only the frame and the jumping mat above the surface. That way you can avoid climbing into the trampoline and you can (or don’t have to) use the enclosure with it, since it is not elevated from the ground.

The underground trampoline comes in different shapes and sizes, like a traditional trampoline, so you can adjust it to the shape and size of your backyard. They aren’t that popular as the traditional trampolines, especially because people aren’t aware that they exist. If you aren’t sure whether to choose in ground trampoline vs above ground, you should know read my post and see the offer of trampolines that go in the ground first before you choose.

In Ground Trampoline

Besides that, ground level trampolines are more challenging because you have to secure trampoline to the ground, which is not as easy as it seems. After all, you have to dig a stable hole that won’t fall down during, even after the entire buried trampoline installation.

Are In Ground Trampolines Safer Than Regular Models?

When it comes to the sunken trampoline safety, the only way I can say that they are 100% safer is that they aren’t elevated from the ground so you can’t get injured entering or exiting the trampoline. Everything else according to the construction or the features is the same as with other types of trampolines. Although you don’t have to use the enclosure net with the trampoline on the floor, I would recommend it so you can avoid all accidents in the beginning. If you are thinking can you put a regular trampoline in the ground, you can, but I wouldn’t recommend that because you will need to make big changes on the trampoline and the cost will only go up.

How To Put A Trampoline In The Ground?

The in-ground trampoline installation doesn’t sound complicated because it consist of 4 steps, but you have to be careful around each step, especially number 1. The spets for putting a trampoline in the ground are:

1) Dig A Hole – you can’t simply do it, you have to think about how to dig a trampoline into the ground, the depth of the hole and how to stabilize the hole. The size of the hole has to be a few inches bigger than the trampoline. Don’t remove the soil because you will need it later. First, dig 10 inches of soil for the main frame. After that you have to dig a hole in the middle according to the size and shape of your sunken trampoline as you can see it on the picture below.

2) Assemble low-to-the-ground trampoline – Assemble the trampoline including the retaining wall above the hole you want to put it. Use the inground trampoline kit and manual instructions so you can be sure everything is in place.
3) Put the trampoline in the hole – and make sure that the frame is at the right height, which means it has to be in level with the surface. Use the rest of the soil you have put aside to fill out the gaps and make sure everything is tight around the trampoline. The in-ground trampoline retaining wall should hold the soil and the trampoline in place.
4) Finish with the venting pads – if you got a trampoline with the venting pads, attach them to the frame and you are ready to enjoy your brand new trampoline.

NOTE: this is not an actuall instruction on how to install an inground trampoline, it is a general explanation on what you should do. During the entire instalation of built-in trampoline into the ground, use the manual instruction you got with the trampoline because models vary from brand to brand.

How Much Does An In-ground Trampoline Cost?

As you can imagine, the in-ground trampoline cost is higher than traditional ones because of the installation so I would recommend it only for people who are handy and experienced with working in the ground and people with a healthy budget, who can hire a professional to install the ground level trampoline. But, if you want to see if there are lower built-in trampoline prices, check out web shops like Amazon, Wayfair or even Walmart because they often have good deals on different products including trampolines. Also, if you are lucky, you can stumble uopn the free shipping option so you don’t have to pay extra for that.

If you can do all that, then I want you to read the reviews of underground trampoline models I have gathered for you. Like I have already said, they come in different sizes and I want to show you the most popular ones, the round in-ground trampoline models and one square underground trampoline. You can choose them by the size or by the shape and to decide which one is better, read my reviews below.

Best In-ground Trampolines For Sale

Jump Power In-ground Rectangle Trampoline

This underground trampoline is the only rectangle trampoline on this list because it is hard to find a rectangle trampoline, even harder to find the in-ground rectangle trampoline. The good thing is that it comes in two sizes, but you have to be sure that the size you want is in stock so you can order it. If it isn’t, you can settle with the other size since they aren’t that different.

JUMP POWER In-ground Rectangular Trampoline

This sunken rectangle trampoline is very durable. It is made of 16-gauge solid galvanized steel frame so you can be sure it will provide you and your family a safe entertainment. The same thing is with the jumping mat and the enclosure system so you can be sure that it is not some cheap model.

The safety enclosure uses curved poles which are also made of steel and they make sure that it is up and tight every second of the trampoline session for your kids. The jumping mat is made of durable materials and it has a logo in the middle, which is great because you can say to your kids to stay as close to the logo possible. That way you can avoid any injuries connected with the enclosure or the spring system.

JUMP POWER In-ground Trampoline

The springs are made of galvanized steel so they are well protected from the weather. Besides that, they are covered with a safety pad so you can be sure that your kids can’t touch them while entering the trampoline.

The quality of this in-ground trampoline with safety net shouldn’t be questionable since it meets or even exceeds all Global Safety Standards and it comes with rust-resistant materials like galvanized steel.

Avyna Pro-Line Underground Trampoline

The next trampoline I want to share with you is a round trampoline made to entertain you and your entire family. It is a good quality trampoline, but it comes only in one size and one color. That size is the 14ft and the color is grey.

Avyna Pro-Line Underground Trampoline

This round floor trampoline is made of high-quality materials and it is made to last. The best proof of that is its warranty on the frame, which is the most important part of every trampoline.

Since this is an in-ground trampoline, it doesn’t require the enclosure around the jumping mat so it is not included in the pack. The size of the trampoline is pretty big and if you tell your kids to jump around the logo (in the middle of the jumping mat) you can be sure that they will have a great time, but they will also be completely safe.

Avyna Underground Trampoline

The entire construction – frame and the springs, are made of galvanized steel so you can be sure it will be a long-lasting backyard equipment. The trampoline is very impressive in the construction and the warranty department, so you can consider a pretty low in-ground trampoline cost for its features.

The installation is also pretty simple but if you are afraid you will do something wrong, you can easily hire a professional or ask a fellow handyman for a help. That is why we have friends and neighbors, right?

Plum® In-Ground Square Trampoline

The next trampoline is again a square in-ground trampoline and when it comes to bounce power, it is right in the middle between rectangular and round models. The size of the square trampoline is 11ft so it is a good size for any backyard.

Plum® Unisex Circular in-Ground Trampoline

Just like other trampolines on the market, this one is made of galvanized steel and it is a good quality trampoline. The jumping mat on the trampoline is made of weather-resistant materials because this is an outdoor trampoline and you can’t remove it that easily once you install it in the ground.

Be careful and follow instruction for installation of the Plum sunken trampoline because it provides a good bounce. That means that there should be enough room below the jumping mat for the mat to stretch before you bounce off it.

Plum in-Ground Trampoline

The recommended age for the trampoline is above 6 years old. Although it is an underground trampoline and it is not elevated from the ground, we still think that the person who is jumping on it should be careful not to jump out of the jumping mat and there should be only one jumper at a time.

That is why we strongly recommend focussing on the logo in the middle of the jumping mat so you can be sure that you are jumping in the center and not at the end of the jumping mat. that is the best way to avoid any types of accidents and injuries.

In-Ground Trampoline Parts And Accessories

Just like other types of trampolines, the sunken trampoline has parts you can replace and some of the most improtant parts are trampoline ground hooks and floor mats. One of the accessories I would suggest you to get is the in-ground trampoline cover which will protect the trampoline when you aren’t using it. I would recommend you to check the brand of the trampoline for replacement parts and if they don’t produce it, check the universal trampoline parts for a replacement.
