What Comes in an In-Ground Trampoline Bundle? A Complete Breakdown for First-Time Buyers

If you’ve been browsing the web for the perfect backyard upgrade, you’ve likely realized that a trampoline is no longer just a metal frame with some springs. The world of backyard fun has evolved, and the in-ground trampoline bundle has become the gold standard for their safety, style, and long-term durability.

At Trampolines.com, we want to make your shopping experience as smooth as the bounce on our mats. In this guide, we’re going to open up the box and show you exactly what you will get when you order an in-ground trampoline bundle from us.

The Trampoline Frame and Jump Mat

At the heart of every in-ground trampoline bundle is the chassis and the surface. Unlike above-ground frames, in-ground frames are engineered to sit in a high-moisture environment. 

The jump mat is equally important. Most high-quality bundles include a "permatex" or polypropylene mat. These materials are chosen for their UV resistance and strength. 

When you unbox your bundle from us, the mat will look like a heavy-duty fabric circle (or rectangle), featuring reinforced V-rings where the springs will eventually attach.

Retaining Wall System or In-Ground Kit

This is the component that separates a true in-ground system from a standard trampoline. A specialized in-ground trampoline bundle includes a retaining wall system that attaches directly to the trampoline frame.

The retaining wall’s job is simple but vital: it holds back the earth. Without it, the walls of your pit would eventually crumble inward, filling the space under your mat with dirt. 

Safety Pads and Edge Protection

Safety is always the top priority. Your in-ground trampoline bundle will include thick, weather-resistant safety pads that cover the springs and the metal frame.
Because in-ground trampolines are flush with the grass, these pads act as a transition zone between the lawn and the jumping surface. The safety pads are usually coated in a heavy PVC skin to withstand the sun’s rays and the foot traffic of kids running on and off the mat all day.

High-Quality Springs and Hardware

You can't have a bounce without the "boing!" Your in-ground trampoline bundle will also include a set of high-tension springs. 

Along with the springs, you’ll find all the necessary nuts, bolts, and specialized frame connectors. Manufacturers usually include a few extra pieces of hardware just in case one rolls away into the grass during assembly.

Ventilation Solutions for Better Bounce

A common question from first-time buyers is: "Where does the air go when I jump down?" If air can't escape from the pit, the trampoline feels stiff and "muffled."

Most in-ground trampoline bundles solve this with integrated ventilation. This might be in the form of a vented jump mat or, more commonly, "vented pads." These pads have mesh sections that allow air to rush out the sides as you land and rush back in as you rise. 

Drainage Components to Prevent Water Build-Up

No one wants to jump into a puddle! While the in-ground trampoline bundle won't include a full drainage system (like pipes or pumps), it typically includes a specialized weed barrier or a geo-textile liner.

This fabric is placed at the bottom of the hole before you set the frame. It allows water to soak into the earth while preventing weeds from growing up through your mat. 

Optional Safety Enclosures

While in-ground trampolines are much safer because they are at floor level, many parents still prefer a net. Depending on the in-ground trampoline bundle you choose, a safety enclosure may be included or offered as a discounted add-on.

These nets are lower-profile than above-ground versions. If your bundle includes a net, it will also come with padded support poles and the necessary brackets to secure them to the frame.

Assembly Tools and Installation Accessories

We know the frustration of starting a DIY project only to realize you don't have the right wrench. Most bundles include the basic tools you need for assembly, including a spring pulling tool.

This T-shaped hook is a lifesaver; it allows you to use your body weight to stretch the springs into place without pinching your fingers. You might also find a specialized hex key or a small spanner tailored to the specific bolts in your in-ground trampoline kit.

Instruction Manuals and Buyer Support

It might seem obvious, but a good in-ground trampoline bundle comes with a comprehensive, illustrated instruction manual. These guides walk you through the "Three Ds": Digging, Designing, and Doing the assembly.

At Trampolines.com, our bundles also come with the "unspoken" component: expert support. If you get stuck halfway through your dig, you can reach out to our team for advice on soil types, hole dimensions, and leveling.

Bonus Upgrades: Covers, Lights, and Add-Ons

To make the deal even sweeter, many holiday or seasonal bundles include "extras" such as:

• Protective Covers: To keep leaves and snow off the mat.
• Anchor Kits: Even though the unit is in the ground, anchors provide extra stability for the frame.
• Basketball Hoops: A favorite add-on for teens.
• LED Lighting: To turn your trampoline into a glowing backyard centerpiece at night.
