In-ground trampolines are quietly taking over Omaha backyards, and it's not hard to see why. They sit flush with the grass — no ladder, no cage-like frame towering over your landscape, no fall from three feet up. A trampoline that disappears into your lawn turns a backyard eyesore into a landscape feature, and that shift is driving the biggest change in residential trampolines in a decade.

This guide covers everything you need to decide: in-ground vs. above-ground, round vs. rectangular, sizing from 8ft to 17ft, the Berg vs. Capital Play brand question, installation expectations for Nebraska soil and weather, and what safety features actually matter. By the end, you'll know exactly which trampoline fits your yard and your family.

In-Ground vs. Above-Ground: Pros and Cons

The biggest advantage of an in-ground trampoline is obvious the moment you see one installed: it eliminates the fall height. An above-ground trampoline puts the jumping surface 2 to 3 feet off the ground. Every exit is a drop. Every miss is a fall. An in-ground trampoline sits level with your lawn, so stepping on and off is as natural as walking across the yard.

The second advantage is visual. Above-ground trampolines are large, domineering structures — a black cage on steel legs that dominates whatever view it's in. An in-ground trampoline disappears into the landscape. The frame is below grade, the padding matches the grass, and from across the yard it reads as a design feature, not playground equipment.

Here's how the two compare head-to-head:

Round vs. Rectangular: Which Shape Fits Your Yard

Shape isn't just about aesthetics — it changes how the trampoline performs and where it fits in your yard. The right choice depends on who's jumping and how much space you have.

Round trampolines pull jumpers toward the center. The springs work equally in all directions, so the bounce naturally recenters you. That makes round the safer, more forgiving shape for families with young kids and casual jumpers. It's also the more compact footprint — a 12ft round trampoline fits in most suburban yards without dominating the space.

Rectangular trampolines deliver a more powerful, directional bounce. The springs along the long sides work harder than the short sides, which means a jumper can generate real height and control along the length. That's why rectangular is the choice for gymnasts, cheerleaders, and athletes who practice skills. The trade-off is footprint: a 14ft x 10ft rectangular trampoline needs a longer, more committed stretch of yard.

If your yard is wide and square, go round. If you have a longer, narrower space — or if someone in the household is serious about training — rectangular gives you more usable bounce surface and better performance for skills.

Sizing Guide: 8ft to 17ft

Size affects three things: how many people can jump at once, how much yard you need, and how much it costs. Here's a practical breakdown based on the sizes available from Berg and Capital Play:

As a rule of thumb, measure your available yard space and subtract 3 feet on each side for safe clearance. A 12ft trampoline needs at least an 18ft x 18ft area. For a 14x10 rectangular, plan for at least 20ft x 16ft. Omaha lot sizes in neighborhoods like Elkhorn, Millard, and Gretna typically handle 12ft to 14ft round models comfortably. If you're on a smaller lot in central Omaha, the 8ft or 10ft options keep the yard functional.

Brand Comparison: Berg vs. Capital Play

Two brands dominate the premium in-ground trampoline market, and they take different approaches. Here's an honest breakdown to help you choose.

Berg is a Dutch manufacturer known for premium European engineering. Their in-ground line uses AirFlow jumping mats that allow 50% more air to pass through, delivering higher, smoother jumps. The TwinSpring Gold angled spring system creates a larger effective jumping area by positioning springs diagonally. Berg's FlatGround models — like the Ultim Champion 16ft — are engineered specifically for truly flush installation, with a patented silent frame profile that sits completely level with the ground. If you want the most refined bounce and the cleanest flush look, Berg is the premium choice.

Capital Play is a UK-based company that emphasizes safety standards and variety. Their in-ground line offers the widest range of sizes and shapes — round from 8ft to 14ft, rectangular from 10x6 to 17x10. Capital Play uses a DualTek double-strength galvanized steel frame (2mm thick, 42mm diameter) with a purpose-built retaining wall system included on every model. Their TDU patented vented safety pads eliminate pad slap noise by allowing air to escape through the pad rather than trapping it. If you want maximum size options and a retaining wall included, Capital Play covers more ground.

Both are excellent brands that Omaha Sports & Games stands behind. The choice comes down to what matters most to you: Berg for the most refined bounce and cleanest installation, Capital Play for the widest range of sizes and a retaining wall on every model.

Installation: What to Expect

Installing an in-ground trampoline is a bigger project than assembling an above-ground model, but it's a one-time job that pays off for years. Here's what's involved.

Excavation

The hole needs to be roughly 30 inches deep and slightly wider than the trampoline frame. For a 12ft round trampoline, that means excavating a cylinder about 13ft across and 2.5ft deep — approximately 8 to 10 cubic yards of soil. In Omaha, where heavy clay soil is common, that clay holds its shape well during excavation but also means you'll need proper drainage to prevent water from pooling in the pit.

Retaining wall

The retaining wall is what keeps the hole from collapsing over time. Both Berg and Capital Play include purpose-built retaining wall systems designed specifically for their frames. The wall sits between the trampoline frame and the surrounding soil, holding back earth, roots, and water. Without a proper retaining wall, the pit will erode — especially in Nebraska's freeze-thaw cycle, where expanding ice pushes soil inward.

Drainage

Water management is critical. Without drainage, the pit becomes a pond after heavy rain. A layer of gravel at the bottom (6 to 8 inches) allows water to percolate into the subsoil. In areas with high clay content or a high water table — common in parts of Omaha and Sarpy County — a drainage pipe connected to a dry well or French drain may be necessary.

Nebraska climate considerations

Nebraska's freeze-thaw cycles are the biggest threat to an in-ground trampoline installation. When water in the soil freezes, it expands and pushes outward against the retaining wall. A properly installed wall with adequate drainage handles this without issue. But a DIY installation that skips drainage or uses an inadequate wall will see the pit narrowing and the frame shifting within a season or two.

Omaha's clay soil is actually an advantage for excavation — it holds its shape, so the hole stays clean during installation. But it's a disadvantage for drainage, because clay absorbs water slowly. That's why a gravel base and, in some cases, a drainage pipe are essential.

Safety Features That Matter

Not all in-ground trampolines are built to the same standard. Here are the safety features that actually matter when you're comparing models.

Retaining wall quality: This is the most important structural component. A purpose-built steel retaining wall — like Capital Play's DualTek system or Berg's FlatGround frame — holds the soil back permanently. A makeshift wall from landscape timbers or plastic edging will fail. Look for galvanized steel, 2mm thickness or better, and a system designed specifically for the trampoline model.

Padding thickness and coverage: The safety pad covers the springs and frame edge. Berg uses extra-thick PVC padding (0.55mm on the Ultim Champion). Capital Play uses TDU patented vented pads that eliminate pad slap — the annoying, potentially startling noise of pads slapping the mat on every bounce. Thicker, wider padding means better coverage and fewer exposed edges.

Spring design: Berg's TwinSpring Gold springs are angled diagonally, which increases the effective jumping area and creates a smoother, more controlled bounce. Capital Play uses straight commercial-grade 8.5" springs (up to 104 on larger models) for maximum power. Both approaches are safe; the difference is feel — Berg is smoother, Capital Play is punchier.

Weight ratings: Capital Play rates their 8ft and 10ft models at 220 lbs, and their 12ft, 14ft, and rectangular models at 264 lbs. These are real structural limits, not marketing numbers. Stay within them, especially with multiple jumpers.

UV-resistant materials: Nebraska summers deliver intense UV exposure. Look for UV-treated jumping mats, PVC padding, and galvanized or powder-coated steel frames. Both Berg and Capital Play use UV-resistant materials across their in-ground lines — this is not a place to cut corners, as sun damage degrades mat elasticity and pad integrity over time.

Weather durability for Nebraska: The low profile of an in-ground trampoline is itself a safety advantage in storms. Where an above-ground trampoline acts like a sail in high winds — and we've all seen them blown across Omaha yards after a summer thunderstorm — an in-ground model has almost no wind exposure. The retaining wall and below-grade frame mean the trampoline stays put in conditions that would send an above-ground model into the neighbor's yard.

In-Ground Trampoline Buying Guide: Frequently Asked Questions

Can I install an in-ground trampoline myself?

Technically yes, but it's a significant project. You'll need to excavate a hole 2.5 feet deep and wider than the trampoline, install a retaining wall, set up drainage, and assemble the frame perfectly level with the ground. Most homeowners in Omaha hire professional installation because the excavation requires equipment and the drainage setup is critical in our clay soil. Professional installation from Omaha Sports & Games starts at $5,500.

How deep does the hole need to be?

Typically 30 inches (2.5 feet) deep, and slightly wider than the trampoline frame. The exact depth depends on the model — Berg FlatGround and Capital Play in-ground kits have specific depth requirements in their installation guides. The hole must be deep enough that the frame and springs sit below grade, with the jumping mat level with the surrounding grass.

Do in-ground trampolines work in cold climates like Nebraska?

Yes, when properly installed. The key is a steel retaining wall and adequate drainage. Nebraska's freeze-thaw cycles put pressure on the pit walls as moisture in the soil freezes and expands. A galvanized steel retaining wall handles this without issue. Without one, the pit will narrow over winter. Both Berg and Capital Play include retaining wall systems designed for this exact challenge.

How much does professional installation cost?

Professional in-ground trampoline installation from Omaha Sports & Games starts at $5,500. This includes excavation, retaining wall installation, drainage setup, frame assembly, and final grading. The final cost depends on your yard's soil type, accessibility for excavation equipment, and drainage requirements.

What size trampoline do I need for my yard?

Measure your available space and subtract 3 feet on each side for clearance. A 12ft round trampoline needs at least 18ft x 18ft. A 14x10 rectangular needs about 20ft x 16ft. For small Omaha yards, an 8ft or 10ft model keeps the space functional. For larger yards in Elkhorn or Gretna, 14ft to 17ft models make the most of the space.

Are in-ground trampolines safer than above-ground?

Yes, primarily because they eliminate the fall height. An above-ground trampoline puts the jumping surface 2 to 3 feet off the ground — every exit is a drop. An in-ground trampoline sits level with the lawn, so stepping on and off is like walking across the yard. The low profile also eliminates wind exposure, which is a real safety issue during Nebraska thunderstorms.

Ready to Transform Your Backyard?

An in-ground trampoline is a one-time investment that changes how your family uses your yard. No cage, no ladder, no eyesore — just a clean, flush surface that's ready to jump on. The right model comes down to your yard size, who's jumping, and whether you value Berg's refined bounce or Capital Play's size variety.
