Inground trampoline

An Etan inground trampoline is a smart way to save space while creating a safe and durable play area in your garden. Our trampolines are produced in Europe from high-quality materials and are designed with a focus on safety, comfort, and long-lasting use. In this blog, we clearly explain the differences between round and rectangular models, which sizes and spring configurations suit your family best, and what to consider when digging in and maintaining your trampoline. We also cover useful Etan accessories such as safety nets, protective pads, and covers, so you know exactly which inground trampoline fits your garden best.

What is an inground trampoline and why do many gardens choose it?

An inground trampoline is a trampoline that is mostly placed in the ground, keeping it low to the lawn and easy to access.

An inground trampoline saves space in your garden and does not obstruct views like a high-standing model on legs. Its low profile does not block sunlight and gives a neat appearance. At Etan, we notice that many Dutch families choose this type for its convenience, safety, and aesthetics. In this text, we use the term inground trampoline as the main keyword, along with variations like “dug-in trampoline,” FlatGround, and InGround.

How does a round inground trampoline differ from a rectangular one?

A round inground trampoline is usually easier to jump on for beginners and younger users, while a rectangular version makes more efficient use of space and is better suited for advanced jumpers.

Advantages of round models

Round mats naturally guide the jumper to the center. This makes them safer for young children and easier to use. Round trampolines are generally more affordable to purchase.

Advantages of rectangular trampolines

Rectangular trampolines provide a more even rebound across the entire mat. They are practical in angular gardens and offer more space for jumps and tricks.

A tip for choosing

Consider your garden layout: does your garden have many straight lines? Then choose a rectangular model. If safety and simplicity for young children are your priority, choose round. Want to see our models? Check our Inground collection: Inground trampolines.

What should you consider regarding springs and maximum weight?

The number and length of the springs determine about 90% of the jumping comfort and the maximum load of your inground trampoline.

Spring length and quantity

Short springs provide a gentle, safe bounce; longer springs offer more height. A family trampoline that needs to support adults has more and often longer springs. Rule of thumb: the more springs, the higher the maximum load and the smoother the bounce.

Steel quality of the frame

Choose a frame with sufficient thickness (preferably ≥2 mm) and a tube diameter of 43 mm. This keeps the frame strong, extends its lifespan, and allows it to handle the forces during jumping.

Practical example

Round inground trampolines in our range usually have 60 to 96 springs and a maximum load of 150 kg. Rectangular models typically have 52–104 springs and can also handle around 150 kg. Consider who will be jumping the most in your family to ensure the frame and springs are suitable.

How deep and how large should the pit be?

The depth and diameter of the pit depend on the trampoline model; always use the manual for exact measurements, but below are average guidelines.

Average pit dimensions per trampoline size

Note: full FlatGround trampolines are level with the grass and require different pit depths than inground models, which sit about 20 cm above ground level.

Step-by-step digging instructions

1. Select the location: at least 2 meters away from obstacles, no overhanging branches, and a level, stable surface.
2. Mark the outline and dig the outer edge first, then the center (bowl-shaped) according to the manual.
3. Lay weed cloth and ensure good drainage. Place the trampoline and check air circulation around the mat.

Is a safety net necessary for an inground trampoline?

A safety net is not always required for an inground trampoline but can provide extra protection, especially for young children.

When should you use a net?

If you have young children or multiple children jumping at once, a net is recommended. Also advisable for higher jumping capacities or uneven surfaces.

Fall zone and spacing

Whether using a net or not: keep a 1 to 1.5 meter clear fall zone around the trampoline. Grass is an excellent surface for this area.

Accessories to enhance safety

• Protective pad (width 28–36 cm depending on model)
• Cover for the mat
• Optional: extra springs for higher loads

Which materials and pad construction matter for durability?

A strong protective pad and good PVC thickness are crucial because inground trampolines get heavy use, and the pad often bears significant weight.

PVC thickness and seams

Use at least 0.55 mm PVC for the pad. This material is stronger and less likely to tear during heavy use. Seams must be well-finished; the pad is meant for protection, not for playing on.

Airflow and the “plop” effect

Proper airflow prevents the “plop” effect when jumping. Some brands include ventilation openings in the pad or air channels under the frame. Ensure your chosen model provides sufficient airflow for a comfortable jump.

Which sizes are popular and which fits your garden?

People often choose medium models (305–366 cm). They offer a good balance between jumping space and garden fit.

Small gardens (≤305 cm)

Round models

Choose round trampolines with a diameter of about 244–305 cm. Suitable for young children and small gardens. Compact yet still fun.

Rectangular models

Choose the rectangular model of 281 × 201 cm. This size is ideal for compact gardens and can be efficiently placed, for example along a fence or in a corner.

Medium gardens (305–366 cm)

Round models

Choose round trampolines with a diameter of 305–366 cm. These sizes fit well in medium gardens and provide plenty of jumping space for children.

Rectangular models

Choose the rectangular model of 310 × 232 cm. This is the most popular size: spacious enough for children and teenagers but still takes up a manageable amount of garden space.

Large gardens (≥366 cm)

Round models

Choose large round trampolines of 366–427 cm. These offer the most play value and allow children to jump and move freely.

Rectangular models

The rectangular model of 380 × 275 cm is ideal for large gardens. Spacious enough for multiple children or teenagers without compromising jumping comfort.

Maintenance tips and smart accessories for longer life

Proper maintenance extends lifespan: protective cover, regular inspection of springs and pad, and cleaning are simple yet effective.

Periodic inspection

Check springs, frame, and seams annually. Replace worn parts in time and watch for rust or pad tears.

Cleaning and storage advice

Clean the mat and pad with lukewarm water and mild soap. Use a cover during long absences or in winter.

Recommended accessories

• Complete safety net (for small children)
• Cover in matching color
• Extra set of springs for higher load
