Why Choose an Inground Trampoline? 7 Smart Tips

An inground trampoline is a smart choice for anyone who wants to save space in the garden while still being able to jump safely. At Etan, we manufacture durable trampolines in Europe that sit close to the ground, are easy to access and integrate beautifully into any garden.

In this blog, we clearly explain what an inground trampoline is, the difference between round and rectangular models, which sizes and spring configurations suit your family, and what to look out for when burying and maintaining your trampoline. We also cover safety, the right quality of the protective padding and air circulation, plus handy Etan accessories such as safety nets and weather covers. Read on to discover which Etan model best suits your garden.

What Is an Inground Trampoline?

An inground trampoline is a trampoline that is placed mostly in the ground, sitting close to ground level.

An inground trampoline provides easier access for children and adults, and takes up less visual space than a model on legs. In practice, these are also called recessed trampolines, buried trampolines or in-ground trampolines. At Etan, we notice that many garden owners opt for this solution because of its clean look and ease of use.

Definition and Operation

An inground trampoline has short legs (approximately 25 cm) and is placed over a pit, so the frame protrudes slightly above ground level. The spring system, jumping mat and frame padding are similar to those of a regular trampoline, but the air displacement and access differ due to the recessed placement.

Difference from a Trampoline with Legs

The main difference is height: trampolines on legs stand higher (60–90 cm approximately) and require a safety net. Inground trampolines sit close to the ground and are often available with or without a net. This means no stepladder is needed and the garden view is less obstructed.

Difference from a Flat-to-the-Ground Trampoline

A flat-to-the-ground trampoline is buried flush with ground level – only the padding border protrudes. Since air cannot move sideways, it must pass through the jumping mat; for this purpose we developed the special OptiFlow jumping mat, which allows 60% more air through than standard mat material.

An inground trampoline is placed at ground level, making it easier and safer to install. The risk of subsidence over time is limited, as not too much soil is removed from the sides.

A flat-to-the-ground trampoline is very difficult to move once buried, unlike an inground trampoline, which can simply be lifted out of its pit.

Note: children find it harder to access an inground trampoline with toys such as go-karts, scooters or bikes, compared with a flat-to-the-ground model. Warning: allowing children to bring such toys onto a trampoline not specifically designed for that purpose is very dangerous.

Who Is It Suitable For?

An inground trampoline works well in gardens where aesthetics and ease of use are important. It is suitable for families with children, but also for adults who want to exercise. Note: sport models without a net are often recommended for users aged approximately 14 and above, due to the greater jump height.

Why Is an Inground Trampoline a Smart Choice for Your Garden?

An inground trampoline saves space, looks neater and is more accessible than a model on legs.

Space and Appearance

Because the unit stays close to the ground, it blends better into the lawn and does not obstruct the view in the garden. Tip: choose a discreet colour for the frame padding to achieve a calm, understated look.

Safety in Use

One advantage is that you can maintain a free fall zone of 1.5 metres all around – that is safer than jumping from a greater height. For families with young children, we often recommend considering a safety net or half-net, even if it is optional on many inground models.

Practical Tip

Tip: place the trampoline at least 2 metres away from trees and other obstacles, and dig a drainage system so that water does not collect in the pit.

How Do You Choose the Right Size and Spring Configuration?

Choose the size and spring arrangement based on who jumps most often and how much space is available in your garden.

Size Guide: Small, Medium, Large

•       Small (Ø 244 cm): suitable for very young children or limited spaces. Max. load often around 100 kg.

•       Medium (Ø 305 cm): the most popular choice, suitable for family play and occasional adult use; max. load 100–150 kg.

•       Large (Ø 366–427 cm): more jumping surface, often rated up to 150 kg; ideal for multiple users or advanced jumpers.

Example: a round model Ø 305 cm often has 60 springs and a maximum load of around 100 kg; a rectangular 214 × 305 cm model often has 52 springs and can support up to 150 kg.

Number and Length of Springs

The number and length of the springs determine approximately 90% of the jumping feel. Shorter springs provide a soft, controllable bounce (great for young children). Long springs and a higher number of springs provide more height and comfort for adults and athletes.

Frame and Padding Quality

Make sure the frame is sturdy (preferably a tube diameter and steel thickness of around 2.0 mm, or at least 1.5 mm) and choose frame padding with at least 0.55 mm PVC and 30 mm thick foam. This prevents rapid wear: on an inground trampoline, the frame padding is often more heavily used because children get on and off without a step.

What Should You Look Out for When Burying and Installing?

When burying an inground trampoline, location choice, depth and good drainage are the most important considerations.

Step-by-Step Burying Plan (Summary)

1.    Select the location: at least 2 metres from obstacles, no overhanging branches.

2.    Check whether there are pipes, cables or other objects underground.

3.    Mark the perimeter and dig the outer ring first, then bowl-shaped towards the centre (follow the model's manual).

4.    Lay weed-control fabric. A bowl shape provides stability and space for the frame.

5.    Place the frame and check the airflow along the sides of the jumping frame.

6.    Check that the trampoline is level.

7.    Check that the padding is secure and that there is a free fall zone of 1.5 metres all around.

Depth and Pit Shape

The exact depth varies per model; always follow the manual. Tip: a slightly bowl-shaped pit provides extra stability and makes it easier to drain water.

Anti-Slam Effect and Air Circulation

Pay attention to air displacement: if air cannot escape properly during jumping, a 'slamming' effect occurs. Some models feature ventilation openings in the padding or integrated air channels under the jumping mat (Airflow systems). Check this when choosing your trampoline.

Maintenance and Lifespan: What Should You Consider?

Good maintenance extends the lifespan of your inground trampoline and keeps safety at a high level.

Daily and Periodic Maintenance

•       Clean the jumping mat and frame padding with lukewarm water.

•       Regularly check springs, seams and the frame for wear and corrosion.

•       Use a weather cover during longer periods of non-use or in winter.

When Should You Replace Parts?

Springs and frame padding are consumable parts. If you notice the springs becoming less supple or the seams in the padding starting to split, schedule a replacement. A trampoline often lasts several years, but with intensive use the springs and padding may need to be replaced sooner.

Accessories That Make Life Easier

Order a weather cover to keep out dirt and rain, and consider a safety net for young children. A protective cover significantly extends the lifespan of the jumping mat and frame padding.

How We Advise

At Etan, we offer tailored advice: we look at the available space, who will be jumping and which features – such as padding thickness and airflow – matter most to you. If you are uncertain about size or model, we are happy to help with a personalised calculation and installation advice.

Etan is your trusted expert in inground trampolines, helping you choose, install and maintain your trampoline for years of jumping enjoyment.

An inground trampoline is a smart way to save space and preserve sight lines in the garden: the unit sits close to the ground, is more easily accessible and looks neater than a trampoline on legs. Important considerations include the right size and spring configuration for the users, a sturdy frame and good padding to limit wear. When burying, pay attention to location choice, sufficient depth, a bowl-shaped pit and good drainage to prevent water build-up and the slamming effect. Safety remains essential: maintain a free fall zone of approximately 1.5 metres all around, consider a safety net for young children and regularly check springs, seams and the frame. Good maintenance – cleaning, covering during prolonged non-use and timely replacement of worn springs or padding – significantly extends the lifespan.
