BERG Champion InGround 14ft Round Trampoline Review (2026)

Full Review

PT Score: 6.5 / 10

An in-ground trampoline isn’t really a different product so much as a different decision. Before you’ve picked a brand, you’ve already agreed to dig a hole in your garden, manage the drainage, and live with a frame that sits a hand’s width above the lawn rather than waist-high on legs. The BERG Champion InGround 14ft is one of the better-engineered ways to act on that decision, and at 430 cm across it’s also the size in this line that two kids can use without colliding. It’s the Champion InGround that BERG actually sells through Amazon US, which makes it the practical choice for most American buyers looking at this range. BERG Toys is a Dutch company, designing and building in Ede in the Netherlands since 1985, which makes them a rarity in this market: a brand that engineers and manufactures in the same place rather than designing in one country and outsourcing the build to another.

Here’s where we have to be straight with you, and it’s the same line we’ve used in every review where it’s true: BERG builds well and documents stingily. The frame is almost certainly strong (more on why below), but BERG doesn’t publish the steel-tube gauge for the Champion line, so our weakest-component scoring won’t credit it. That, plus a warranty structure that’s generous on the frame and thin on everything else, lands the Champion InGround 14ft at 6.5 out of 10. The limiting factor is the frame, and not because we think it’s weak. We score it at floor because we can’t verify the number that would tell us otherwise.

Key Specifications

A word on the price line. The 14ft Champion InGround sits firmly in premium-tier pricing, and we’re not going to quote a live number for it. The Amazon listing wasn’t showing a confirmable buy-box figure when we put this together, and BERG’s own configurator pricing moves around. What we can tell you is the shape of it: this is well into four figures for a 14-footer with the net, and comfortably more than a comparable above-ground round of the same size, because of the reinforced in-ground frame and the vented mat. It’s also more than the smaller 11ft Champion. We’ll come back to what that does to the value math at the end.

Who Is It For?

Picture the buyer this trampoline was actually built for. They’ve already walked the garden, decided they don’t want a waist-high frame dominating the lawn, and they’ve made peace with the idea of a digger turning up for a day. Maybe they want the lower fall height for younger kids, maybe they just want the cleaner look, maybe both. For that person, the dig isn’t a cost to be talked out of. It’s the whole point. The BERG Champion InGround 14ft serves them well: it’s a purpose-built in-ground frame with a vented mat and a generous spring count, from a brand that’s been doing this for forty years, and at 430 cm it’s big enough that two kids aren’t constantly bumping into each other.

It also makes sense for the buyer cross-shopping a Springfree. That’s the “I want premium and I want safe, but do I really want to dig?” shopper, and they deserve the trade-off laid out plainly. The BERG gives you a livelier, springier bounce and a hole to dig. Springfree gives you no metal springs and no excavation, with a softer rebound as the price of that. Neither answer is wrong. They’re just different priorities.

The Champion InGround 14ft is also the right call for someone who wants BERG quality and has the yard for a proper full-size round. BERG does make an 11ft (330 cm) Champion InGround for tighter gardens, but it isn’t sold on Amazon US, so for most American buyers the 14ft is the one you can actually order without going hunting on a specialist dealer’s site. And if you’re a long-horizon buyer registering for the 13-year frame warranty and expecting a decade-plus of use, the Champion is built for that timeline.

The In-Ground Install

This is the part of the buying decision that the marketing photos quietly skip, so let’s spend some time on it.

BERG specifies a bowl-shaped pit for the InGround, wider at the top and tapering shallower toward the centre’s flat base. Not a straight-sided cylinder. The 14ft’s pit is bigger than the 11ft’s roughly 75 cm bowl, both deeper and wider, but BERG doesn’t publish a single neat figure for the 430 cm model, so plan for the frame diameter plus enough room to work and to get a drainage layer in. Realistically this is a job for a mini-digger or a landscaper. It is not an afternoon with a spade and a willing teenager, and at this size it’s even less of one than the 11ft was.

The drainage is the real risk, and it’s the classic way in-ground trampolines fail. A pit that holds water rots the pad from below, breeds mosquitoes, and turns the bottom of your nice new install into a swamp. BERG and most installers recommend a gravel drainage layer or a soakaway at the base of the pit. BERG’s own manual isn’t especially detailed on this point, so treat it as your problem to solve rather than something the box will sort out for you. If your soil drains poorly, factor a proper soakaway into the budget before you commit.

And the rim. An in-ground BERG is not flush with the lawn. The top rail sits about 20 cm above the grass, roughly a hand’s width proud, exactly as it does on the 11ft. That gap is deliberate: it’s there for airflow under the mat and to keep the frame edge clear of soil and standing water. So an in-ground BERG looks far more integrated into the garden than a trampoline on full-length legs, but it isn’t a seamless surface you could mow straight over. If the brochure shots had you imagining something invisible, adjust expectations down a notch. It still looks great. It just isn’t magic.

If you want a fuller walkthrough of whether the whole in-ground approach is right for your yard, we’ve written that up separately: is installing an in-ground trampoline a good idea?

InGround vs FlatGround vs Regular

BERG sells the Champion in three installation styles, and it’s worth knowing which one you’re actually buying, because they’re the same trampoline with very different ground-prep demands.

InGround is the one this review covers. The frame goes into a dug pit so the rim sits at lawn level (well, about 20 cm above it). Maximum garden integration, maximum digging.

FlatGround sits on a set of short legs at roughly the same low height without the full excavation. Much less digging, but it isn’t truly ground-level, and you still have to manage the airflow gap under the mat. It’s the middle option for someone who wants “low” without “landscaper”.

Regular is the conventional waist-height trampoline on full-length legs. Cheapest of the three, no digging at all, but you lose the low fall height and the clean look entirely.

If you want the genuine ground-level result and you’re willing to dig, get the InGround. If you want low-ish without the excavation, FlatGround. If frame height doesn’t matter to you, the Regular saves money. Just don’t buy the InGround and then be surprised by the hole.

Bounce and the AirFlow Mat

This is where BERG earns its keep. The Champion InGround 14ft runs a full set of TwinSpring Gold springs, more than the 96 on the 11ft model, though BERG doesn’t publish the exact figure for the 430 cm size. The “TwinSpring” name describes a real design rather than marketing gloss: instead of one coil per anchor point, you get two springs mounted in a V-shape, which spreads the load and gives a longer, softer pull. The “Gold” tier is the larger-diameter, fully galvanised version BERG uses on the Champion line, and it carries a 5-year warranty. Spread that count around a 430 cm rim and you get a deep, even rebound across a generous jumping area. On the bounce side, this is the trampoline’s clearest strength.

But the more important thing for an in-ground install is the mat, and here’s why. Drop a normal trampoline into a sealed pit and you’ve created a problem: every time someone jumps, the mat pushes down on a trapped column of air with nowhere to go. The air resists, and the bounce goes mushy and dead. It’s the single most common reason a cheap “in-ground” conversion feels disappointing. BERG’s answer is the AirFlow mat, a woven construction with a perforated weave that lets air pass through the mat surface rather than compressing it under the deck. That’s the whole point of buying a purpose-built in-ground trampoline rather than dropping a regular one in a hole. The vented mat keeps the rebound lively in exactly the situation that kills it on lesser setups.

We do have to flag one gap: BERG describes the mat as “woven” and brands it AirFlow, but doesn’t disclose the actual fibre (polypropylene, polyester, whatever it is). So while the technology is clearly the right one for the job, we can’t tell you how the material itself compares to a published-spec mat like the cross-sewn polypropylene you’ll find on some premium rivals. That, plus a mat warranty of only 2 years, keeps the mat component out of the top tier of our scoring.

Safety

The usual caution applies, because it doesn’t stop being true: trampolines carry risk no matter how well they’re built, and supervision plus one-jumper-at-a-time is on you, not on the equipment. BERG, like every responsible manufacturer, recommends a single jumper at a time even though the 600 kg structural rating means the frame won’t notice a couple of kids on it at once. The 430 cm deck does at least mean that when two kids inevitably climb on anyway, they’re not stacked on top of each other the way they’d be on a small round.

The genuine safety case for going in-ground is the fall height. The Champion’s mat sits roughly at ground level, so a tumble off the side is a short drop onto grass rather than a metre-plus fall from a frame on legs. That’s the main reason a lot of parents choose in-ground in the first place, and it’s a real advantage over an above-ground trampoline.

Which raises the question of whether you need the net. Less than you do on an above-ground one, but it still depends on who’s jumping. For older kids and adults bouncing sensibly, plenty of in-ground owners run without a net at all. For young children (BERG rates this trampoline 6+), for boisterous group sessions, or for anyone near a hard edge like a patio, keep the net up. The convenient thing here is that this bundle includes the net anyway, so the easy answer is: use it while the kids are small, reassess later. The net it comes with has foam-covered poles and a self-closing, zippered entrance, and the listing pairs it with the Safety Net Deluxe specifically, though it’s worth checking the title because BERG sells some Champion configs with the simpler Comfort net or as frame-only. BERG doesn’t publish how many poles the net uses, mind you, which is one more spec we’d like to see and can’t.

The 30 mm safety pad sits over the spring zone the way it should, with a waterproof PVC cover, which matters more in a pit than it does up on legs. Like the pad on every trampoline, it’s the part most likely to wear first under UV and weather, and at a 2-year warranty it’s worth budgeting a replacement somewhere down the line. That’s realism, not pessimism.

The Warranty Is Lopsided

We need to say this plainly because a buyer spending well into four figures deserves to hear it. The frame warranty on the Champion InGround is excellent: 10 years as standard, extending to 13 if you register the product for free on berg.com. That’s class-leading. But the mat, the pad, and the net are all covered for just 2 years each. The springs sit in between at 5 years. For comparison, a premium rival like ACON gives 5 years on the mat.

So the picture is “great frame, mediocre everything-else”. The parts most likely to wear out under daily use and weather, the mat and the pad, carry the shortest cover on the trampoline. It doesn’t make the Champion a bad buy. It does mean you should price in eventual replacement pads and budget accordingly, and not assume the warranty has you covered for the long haul on the consumables.

What’s in the Box

You get the in-ground frame, the AirFlow mat, the full set of TwinSpring Gold springs, the 30 mm safety pad, the safety net (poles and netting), the assembly hardware, and the manual. What you don’t get, and will want, is the drainage material for the pit and possibly a spring-pull tool depending on what’s in the kit. Build it on a day you’ve cleared, with a second adult, after the digging’s done and the pit’s drained and ready. As with any netted trampoline, the enclosure is where the afternoon goes, and a 430 cm net is more of it than the 11ft’s.

Who This Is For

• Buyers who’ve already committed to in-ground. The garden-aesthetics crowd, or parents who want the lower fall height of a ground-level deck. The dig is a feature to you, not a cost, and the Champion InGround 14ft is a well-built way to get it at a genuinely useful size.
• BERG-curious buyers comparing against Springfree. If you want premium and safe and you’re weighing “dig or don’t dig”, the BERG gives you a livelier bounce plus a hole. Springfree gives you no springs and no excavation with a softer rebound. Pick the trade-off that fits your priorities.
• US buyers who want a BERG in-ground they can actually order. BERG also makes an 11ft Champion InGround, but it isn’t on Amazon US, so the 14ft is the practical choice in this line for most American buyers. If your yard genuinely caps you at 11 ft, you’d have to buy that one direct from us.bergtoys.com or a specialist dealer.
• Long-horizon buyers. Register for the 13-year frame warranty, expect a decade-plus of use, and you’re buying for the timeline this frame is built for.

Who This Is NOT For

• Anyone who wants a perfectly flush, invisible install. It sits about 20 cm proud of the lawn, and no spring trampoline is ever truly flush. If seamless is the dream, this isn’t it.
• Anyone unwilling or unable to dig a proper bowl-shaped pit with drainage. This is a real excavation, and a 430 cm one is bigger than the 11ft’s. If you won’t dig it and won’t pay a landscaper to, buy an above-ground model.
• Bounce-per-dollar shoppers. A 14 ft above-ground trampoline gives you far more bounce for far less money. The BERG premium is for the in-ground engineering, not the size.
• Small-yard buyers. If you genuinely don’t have room for a 430 cm frame plus a working pit around it, this isn’t your trampoline, and the BERG 11ft isn’t easy to buy in the US. Look at a smaller above-ground round like the ACON Air 10ft instead.
• Buyers who need a specific US ASTM listing in writing. BERG is CE-certified. We couldn’t confirm a specific US ASTM standard for this SKU. If that documentation matters to you (a school, an insurer), ask BERG directly or buy a brand that publishes it.
• Renters and anyone who might move soon. You can’t take the hole with you, and back-filling a 430 cm pit is its own job.

How It Compares

The honest framing here is that the BERG Champion InGround 14ft isn’t really competing on price. The buyer looking at it has already decided they’re digging a hole. So the comparison that actually matters is “BERG in-ground vs Springfree above-ground-but-safe” (a do-I-really-want-to-dig question), with a side note about the smaller 11ft for anyone whose yard is tight.

On the size question: BERG does make an 11ft (330 cm) Champion InGround in the same line, with the same TwinSpring Gold and AirFlow construction but 96 springs, a 100 kg per-jumper limit, and a 500 kg test rating. It’s the one for a genuinely small yard. The catch is that it isn’t sold on Amazon US, so you’d be buying it direct from us.bergtoys.com or a specialist dealer rather than off the listing this review covers. For most US buyers, the 14ft is simply the practical choice in this line, and the value-per-foot is better at 430 cm anyway. If your yard is too small even for the 11ft, point yourself at a quality small round like the ACON Air 10ft instead, which is above-ground and skips the hole entirely.

On the do-I-dig question: Springfree’s Medium Round Smart throws the whole premise out. No metal springs at all, flexible composite rods below the mat, frame outside the jumping zone, and no excavation needed because it stands on legs designed to be safe at that height. It’s the safest residential design on the market. But the bounce is softer and less responsive than any spring system, and a jumper who wants real rebound will feel that immediately. If safety is your single overriding priority and you’ll trade bounce feel for it, Springfree. If you want the livelier bounce and you’re happy to dig, the BERG.

For another in-ground point of reference, the JumpPower in-ground rectangular is the rectangle option, though it’s harder to actually buy. Anyone whose appetite is running toward a bigger premium build (and a rectangle instead) should look at the ACON X 17ft. And for the broader picture, our round trampolines category and our trampoline buying guide cover the rest of the field.

The Price: Is It Worth It?

Here’s the value math. The 14ft Champion InGround is premium-tier money: well into four figures for a 14-footer with the net, and comfortably more than a comparable above-ground round of the same size. The Amazon listing wasn’t showing a confirmable price when we wrote this, so we’re not going to quote a stale number. What’s not in doubt is what you’re paying for: the reinforced in-ground frame, the full set of TwinSpring Gold springs, the vented AirFlow mat, the included net, and the BERG name. It’s also more than the smaller 11ft Champion, which is what you’d expect from a larger frame. If you want to see the live figure, BERG’s US listing is here: check current price on Amazon.

So is it worth it? For the right buyer, yes. If you specifically want a near-flush in-ground install, you’ve accepted the dig, and you want BERG-grade build behind it at a properly useful size, the Champion InGround 14ft delivers exactly that, and the things it does well (the spring count, the vented mat, the 13-year frame warranty) are the things that matter for a long-haul in-ground trampoline. For a buyer just chasing bounce-per-dollar, no. An above-ground trampoline gives you more for less, every time. Re-check the live Amazon price before you buy. If it’s come down meaningfully, the value case only gets stronger, though it wouldn’t change our overall score: the frame is what’s limiting us there, not the price.

Our Verdict

The BERG Champion InGround 14ft is a well-engineered in-ground trampoline from a brand that’s been doing this for forty years and builds where it designs. The TwinSpring Gold springs are a genuinely generous count for a 14-footer, the AirFlow mat is the right answer to the dead-bounce problem that plagues sealed-pit installs, the net is included, and the 13-year registered frame warranty is class-leading. It’s also the Champion InGround that US buyers can actually order through Amazon, which counts for something when the smaller 11ft is direct-purchase only over here. For a buyer who’s already committed to the in-ground approach, this is one of the best ways to act on that.

We score it 6.5 out of 10, and the limiting factor is the frame, not because we think it’s weak but because BERG won’t publish the steel-tube gauge for the Champion line and our methodology doesn’t credit specs we can’t verify. The 10-year warranty, the 600 kg test rating, and BERG’s Dutch-engineering reputation all suggest the frame is strong. But “probably strong” isn’t a published number, and we score what we can confirm. Combined with a couple of other undisclosed specs (the exact spring count for this size, the enclosure pole count, the mat fibre, the pit dimensions) and a warranty that’s thin on the mat, pad, and net at 2 years each, the pattern is familiar: BERG builds beautifully and documents stingily.

It’s not for everyone. If you want a perfectly flush install, this sits 20 cm proud. If you won’t dig a proper bowl-shaped pit with drainage, this isn’t your trampoline. If you’re chasing bounce per dollar, an above-ground model wins. And if you need a specific US ASTM listing in writing, you’ll have to chase BERG for it. But if you’ve decided you want the ground-level look and the lower fall height, and you want BERG build behind it at a size two kids can actually share, the Champion InGround 14ft earns its place. Just go in knowing the hole is the real project, and the drainage is the real risk.

Frequently Asked Questions

Q: Is an in-ground trampoline worth it compared to an above-ground one?

A: It depends what you’re optimising for. In-ground trampolines like the BERG Champion sit at lawn level, so the fall height off the mat is much lower, the trampoline doesn’t dominate the garden visually, and there’s no tall frame to mow around. The trade-offs are real, though. You have to dig and pay for a proper pit, the drainage becomes your problem, and the trampoline costs a good deal more than a comparable above-ground model because of the reinforced in-ground frame and the vented mat. If you’ve already decided you want the ground-level look and the lower fall height, and you’re prepared for the excavation, an in-ground trampoline is worth it. If you mostly want a lot of bounce for your money, an above-ground model wins on value every time.

Q: How deep do you have to dig for a BERG Champion InGround 14ft?

A: BERG specifies a bowl-shaped pit, wider at the top and tapering to a flatter base, not a straight-sided cylinder. The 14ft’s pit is bigger than the 11ft’s roughly 75 cm bowl, both deeper and wider, but BERG doesn’t publish a single tidy figure for the 430 cm model, so plan for the 430 cm frame plus enough margin to work and to fit a drainage layer. This is definitely a job for a mini-digger or a landscaper, not an afternoon with a spade.

Q: Is the BERG Champion InGround flush with the ground?

A: Not quite, and that’s deliberate. The top rail sits about 20 cm above the lawn, roughly a hand’s width proud of the grass. That gap is there for airflow under the mat and to keep the frame edge clear of soil and standing water. So an in-ground BERG looks far more integrated into the garden than a trampoline on full-length legs, but it isn’t a seamless, invisible surface. If the marketing photos had you picturing something you could mow straight over, adjust expectations slightly.

Q: Does the BERG Champion InGround 14ft come with a safety net?

A: This particular configuration does. The Amazon SKU (B07GC2GKD1) is the “+ Safety Net” bundle, and the listing pairs it with the Safety Net Deluxe, which has foam-covered curved poles and a self-closing, zippered entrance rather than a basic straight-pole design. Worth checking the listing title before you buy, though, because BERG sells some Champion configs with the simpler Comfort net or as frame-only.

Q: Do you actually need a safety net on an in-ground trampoline?

A: Less than you do on an above-ground one, but it still depends on who’s jumping. An in-ground trampoline’s mat is roughly at ground level, so a fall off the side is a short one onto grass rather than a drop from a metre up, which is the main safety case for going in-ground in the first place. For older kids and adults bouncing carefully, plenty of in-ground owners run without a net. For young children (BERG rates this trampoline 6+), for boisterous group jumping, or for anyone near a hard edge like a patio, keep the net up. Since this bundle includes the net anyway, the easy answer is to use it while the kids are young and reassess later.

Q: What’s the difference between the BERG Champion InGround and the FlatGround version?

A: Same trampoline, different installation. InGround means the frame goes into a dug pit so the rim sits at lawn level (well, about 20 cm above it). FlatGround means it sits on a set of short legs at roughly the same low height without a full excavation, so much less digging, but it isn’t truly ground-level and you still need to manage the airflow gap under the mat. And then there’s the Regular version, the conventional waist-height trampoline on full-length legs. If you want the genuine ground-level look and you’re willing to dig, get the InGround. If you want low-ish without the excavation, FlatGround. If frame height doesn’t matter to you, the Regular is cheaper. This review covers the InGround.
