Avyna Pro-Line 10×17 Rectangle In-Ground Trampoline Review (2026)

Full Review

PT Score: 5.5 / 10

Most American buyers have never heard of Avyna. That’s a function of how it sells. Behind the brand sits Tol Outdoor Leisure B.V., a Dutch company founded in 1999 that builds in its own Vietnam factory and has specialized in flat, in-ground systems for most of its life. It sells wholesale in the US through dealers, with no consumer channel of its own. The 10×17 is the largest standard Pro-Line rectangle, and since the 2025 dealer rebuild you may see it listed as the “Avyna Premium Rectangle In-Ground”.

Here’s the thing no dealer blog will lead with: the base 10×17 ships with no safety enclosure. None. Avyna’s net for this size is a separate $500 plus $149 shipping, taking the real out-the-door figure near $3,944 before anyone picks up a shovel, and it carries a one-year warranty on a trampoline whose frame is covered for life. That’s the shortest cover on the product, sitting on the component whose entire job is keeping jumpers on the mat.

We score it 5.5 out of 10. The trampoline itself is good. It’s sold incomplete.

Key Specifications

Every line above comes from Avyna’s US dealers rather than from Avyna. During our research pass, avyna.com, avynausa.com and trampoline.nl were all unreachable, and the US arm runs a wholesale model with no consumer-facing product pages. Dealer copy is usually accurate, but it isn’t the manufacturer speaking, and on this brand it contradicts itself from page to page.

Frame and Build Quality

The frame is the part you’ll still own in twenty years, and Avyna covers it for life. That’s the strongest frame warranty in the category, past the ten-year terms from BERG and North, and on buried steel, where corrosion is what eventually kills the product, that’s the term that matters most.

The gauge story is messier. This model is listed with an 11 gauge upper frame and a 14 gauge lower frame, but the same dealer’s round models show 14 gauge only, the brand page quotes 3.2 mm (nearer 10 gauge), and general marketing says a flat “11-gauge hot-dipped galvanized”. Those aren’t rounding errors: 11 gauge is about 3.04 mm against 14 gauge at roughly 1.9 mm. So our read on the frame is positive with a condition attached. The double-galvanized build and the lifetime cover hold up. The printed numbers don’t reconcile, so weight the warranty more heavily than the gauge figures.

Springs, Mat and How It Bounces

The 10×17 carries 128 springs: 120 at 8.5 inches around the perimeter, plus 8 shorter 5.5-inch springs in the corners. That corner detail matters, because rectangles bounce unevenly at the corners on a single spring length, and shortening them keeps mat tension consistent across the whole deck. All 128 are double-galvanized and covered for ten years, double what BERG and North offer. Wire gauge isn’t published, so we can’t compare the steel directly, but 128 springs with a decade of cover is a serious package. It’s the best thing about this trampoline.

Avyna calls the mat “Air X-TREAM”, a polypropylene homopolymer, UV-protected, with a 4-inch flap over the spring gap and a vented weave the dealers market as 70% more airflow. On an in-ground, venting is the whole ballgame. A sealed mat over a pit traps air, kills the bounce, and makes every landing thud. Our reservation is the cloth, because polypropylene ranks below Permatron and polyethylene in our materials order, and the mat is covered for three years against the five from ACON or North.

The safety pad is treated vinyl over thick foam and described as waterproof, which is what you want on something living at lawn level catching sprinkler water. Thickness isn’t stated, but three years of pad cover beats the two you get from ACON and North.

The Dig: What an In-Ground Install Really Takes

Published excavation for the Pro-Line runs roughly 30 to 40 inches depending on model, with 40 inches (102 cm) cited for this line and at least 36 inches from the center of the mat to the pit floor. Across a 10 by 17 foot footprint, a flat dig at full depth moves something like twenty cubic yards of soil, and the pit needs a gravel drainage layer or you’ve built a pond with a trampoline lid on it.

Two things the listings gloss over. Avyna doesn’t include a retaining wall the way North does, so budget for one to stop the sides slumping in and burying the frame. And no in-ground trampoline sits truly flush, since the pad and frame edge stand slightly proud of the lawn on every system we’ve reviewed. Our in-ground trampoline installation guide covers drainage, walls and leveling. Read it before you call a landscaper.

Safety and the Enclosure You Have to Buy

Trampolines carry injury risk. One jumper at a time is the rule that keeps people out of the emergency room, and no piece of equipment substitutes for supervision.

In-ground earns a clear safety advantage before you add anything. The deck sits at ground level, so there’s no four-foot fall off the side, which is the most serious failure mode of an above-ground trampoline. That’s a fair reason to think the net matters somewhat less here than it does on a raised frame.

It still matters. A net stops a jumper traveling sideways from landing on concrete, a fence post, or a sibling standing at the edge. Avyna does sell one for this model: 8 curved poles, about six feet tall, “High Grade Nylon Mesh”, $500 plus $149 shipping, one-year warranty. Set that single year against the lifetime frame and the ten-year springs and you can see where the manufacturer’s confidence sits. Avyna treats the enclosure as an accessory. The rest of the category treats it as equipment.

Standards get cited loosely in this category, so treat any of them carefully. You’ll sometimes see ASTM F2970 attached to in-ground trampolines. That’s the trampoline-park standard and it doesn’t apply to a backyard trampoline. The consumer standard is ASTM F381, and enclosures are covered by ASTM F2225. We couldn’t find either cited for this product. A TUV and ASTM claim does exist elsewhere in the Avyna range, but the version we could trace covers the above-ground models. If you need documented certification for a school, a club or an insurer, get it from the dealer in writing before you order.

Capacity is muddled as well. The listing states a 1,750 lb maximum weight limit, a roughly 1,100 lb “maximum test capacity” figure also circulates, and no recommended single-jumper weight appears anywhere, where North prints 242 lbs. None of that changes how you should use it, but a buyer at this price is entitled to a number that agrees with itself.

Warranty

The warranty is two warranties, really: a strong one on the frame, a thin one on everything else. Lifetime on the frame is class-leading. Ten years on the springs is strong. Then it drops: three years on the mat, three on the pad, one year on the net. Springfree, at the other end of the market, covers mat, pad and net for ten years apiece.

Call it the strongest frame warranty in the category and you’re on safe ground. Call it the strongest warranty and you’re not. Avyna wins on the part that never wears out and loses on everything a trampoline consumes. There’s no downloadable warranty document either, so confirm transferability with the dealer before you pay.

The Same Money, a Different Trade-Off

Nobody selling this product puts the following side by side, so here it is.

The 10×17 costs $3,295 without a net. The 10×14 Pro-Line Kit with Enclosure costs the identical $3,295 with the net in the box. Same money. Your real choice is three feet of extra length against an included safety system, and if you want both you’re at roughly $3,944 for the 10×17 plus its enclosure. For a household with young children we’d take the 10×14 kit and not think hard about it. For an older-jumper household set on maximum length, or a buyer who intends to build their own enclosure, the 10×17 is the right one. What we’d push back on is buying the 10×17 without knowing the trade-off existed.

Buying It: Amazon or the Dealer, It’s the Same Company

Buying it is the one easy part. The Amazon seller for Avyna in the US is trampolines.com, trading as Trampolinesdotcom, an authorized dealer, and on the base 10×17 the Amazon and dealer-direct prices are identical to the dollar. On the bundled kits it tilts the other way: those carry a premium on Amazon, but the premium is smaller than the $649 an enclosure costs separately, so the bundle works out cheaper than a base unit plus a net. Check both carts before you commit.

Who This Is For

• Buyers already committed to a rectangle in-ground dig who want the largest standard bounce area Avyna builds, on a frame guaranteed for life.
• Bounce-quality seekers. 128 springs over a vented mat is the liveliest configuration in our in-ground set, and the shortened corner springs are a detail most rivals skip.
• Households that already own or intend to build an enclosure, or that plan to run netless at ground level with older, competent jumpers.
• Long-horizon owners for whom the lifetime frame warranty is the deciding number, and who accept mats and pads as consumables they’ll replace themselves.

Who This Is NOT For

• Anyone with young children expecting a complete safety system in the box. It isn’t there. Budget the extra $649 from the start, or buy the 10×14 Kit with Enclosure at the same price.
• Anyone who needs documented ASTM F381 or F2225 compliance. Neither is cited for this line. If a school, club or insurer needs it in writing, confirm with the dealer before ordering.
• Anyone unwilling to excavate 30 to 40 inches across a 10 by 17 foot footprint, with drainage and a retaining wall, or to pay a landscaper to do it.
• Spec-sheet buyers. Avyna publishes less, and less consistently, than BERG or North, and none of it comes from the manufacturer directly.
• Bounce-per-dollar shoppers. An above-ground premium rectangle like the ACON X 17ft gives you far more trampoline per dollar if you aren’t committed to burying it.

How It Compares

Check the enclosure row first. That one line is most of this review. Every other in-ground trampoline we cover on Amazon puts a net in the box. The BERG Champion InGround manages it at roughly half the money with a ten-year frame warranty behind it, which makes it the easier recommendation for most families despite being a smaller round, and the budget JumpPower In-Ground includes a zipper net on 58 springs. The North In-Ground 17×12 is the closest match on shape and charges separately for its net too, but it puts a pre-built retaining wall in the kit. Avyna’s answer is frame warranty, spring warranty and spring count, and on those three it beats all of them.

Our Verdict

The Avyna Pro-Line 10×17 is a well-engineered in-ground trampoline from a manufacturer with its own factory and two decades in the category. The 128-spring configuration with shortened corner springs is the best spring package in our in-ground set and it’s backed for ten years, the lifetime frame warranty is class-leading, and the vented Air X-TREAM mat answers the dead-bounce problem that ruins cheap sunken installs.

We score it 5.5 out of 10, and the enclosure is why. A trampoline at this price shouldn’t arrive without a safety net, and this one does. The net is a $649 extra carrying one year of cover, on a trampoline whose frame is warranted for life. We found no ASTM F2225 claim for it, and no ASTM F381 statement for the trampoline itself. The 10×14 kit costs the same with a net included.

Buy this one if you’ve done that math and still want the longer deck, if you’re comfortable sourcing your own enclosure, and if a lifetime frame warranty closes the deal. Buy the 10×14 kit instead if there are small children in the house. What we wouldn’t do is order the 10×17, dig a 40-inch hole, and find out the net was never in the box.

Frequently Asked Questions

Q: Does the Avyna Pro-Line 10×17 come with a safety net?

A: No. The base 10×17 ships without one. Avyna’s dealers sell a net for this size at $649 delivered, so budget close to $3,944 in total before any excavation. The 10×14 kit is priced identically to the bare 10×17 and includes its net, so buyers who want a safety system in the box should take the smaller deck.

Q: How deep do you dig for an Avyna in-ground trampoline?

A: Budget for a pit around 40 inches (102 cm) deep on this line, with the published range across the Pro-Line range sitting somewhere between 30 and 40. You also want a clear 36 inches from the middle of the mat down to the floor of the pit. On a footprint this size that’s a lot of soil to shift, and whatever you dig needs a gravel drainage layer underneath, or it will sit full of water. There’s no retaining wall in the box either, so price one in from the start. Our in-ground installation guide walks through both decisions.

Q: Who makes Avyna, and is it a good trampoline brand?

A: The brand belongs to Tol Outdoor Leisure, a Dutch business going since 1999 that runs its own factory in Vietnam. Flat and in-ground systems are what it has built its name on, and the engineering on this model holds up. Transparency is where it falls down. There’s no US consumer website, so every spec reaches you second-hand, and the dealers carrying it quote the frame gauge three different ways.

Q: Avyna vs BERG: which in-ground trampoline is better?

A: For most families, BERG. The BERG Champion InGround 14ft includes its deluxe net, costs roughly half as much, carries a 10-year frame warranty (13 with registration), and we score it 6.5 out of 10. Avyna wins where longevity is decided, with a lifetime frame, ten years of spring cover against BERG’s five, and a far larger rectangular deck. Pick the Avyna if you want the biggest, liveliest surface and you’re willing to source an enclosure yourself. Pick the BERG if you want something that arrives ready to use.

Q: What warranty does Avyna offer?

A: Lifetime on the frame, 10 years on the springs, 3 years on the mat, 3 on the pad, and 1 year on the enclosure net, quoted consistently by three independent US dealers. The frame and spring terms lead the in-ground category. The soft goods trail it badly by premium standards. There’s no published warranty document, so get the terms in writing.

Q: Is a rectangle in-ground trampoline better than a round one?

A: For performance, generally yes. A rectangle gives consistent bounce across the whole deck instead of pushing jumpers toward the middle the way a round does, which is why gymnasts train on rectangles. Rounds are cheaper, need a smaller hole, and their self-centering bounce is arguably safer for small children learning to jump. For in-ground the rectangle’s cost is the dig: a 10 by 17 foot pit is a lot more earth than a 14-foot round. Our trampoline buying guide covers how to pick a shape.
