Vuly Trampolines Review (2026): The Zero-Gap Net, the 330 lb Limit, and the Standard Vuly Does Not Name

What Vuly sells in the US

Vuly's US store currently lists five trampolines: the Junior, the Ultra 2 and Ultra 2 Pro, and the Thunder 2 and Thunder 2 Pro. The previous-generation Thunder and Ultra pages are still live and still selling, which is where the practical trap is. The two generations publish different numbers. Vuly gives the Thunder 2 an overall diameter of 13.42 ft (L), 15.39 ft (XL) and 17.52 ft (XXL) with a 6.27 ft net and a 9.45 ft total height; the older Thunder is published as 12 ft wide with a 10 ft 4 in mat (Large) and 14 ft 8 in wide with a 12 ft 4 in mat (Extra Large). The warranty splits differ too: 10 years on the frame, 5 on the mat and 1 on the net, poles and leaf springs for both Thunder generations, but 5 years on the frame for the Ultra and Ultra 2 against 10 for the Thunder. A marketplace listing can carry either name, so match the dimensions on the listing to the spec sheet before you buy rather than trusting the model name.

We review the Thunder and the Ultra here because they are the two models Vuly publishes full specifications for in the US: spring design, net behavior, frame treatment, certification, static load and user weight. The Thunder 2 and Ultra 2 pages publish dimensions and warranty only. Where a fact below comes from a generation-specific page, the source says which.

The leaf spring, and what it replaces

On a conventional trampoline the springs sit at the edge of the mat, under a pad, exactly where a jumper who drifts sideways lands. Vuly's answer on the Thunder is a compact leaf spring, shaped from a single piece of steel, pre-curved and with no welds or rivets: 56 of them on the Large, 64 on the Extra Large, mounted below the jumping surface rather than around it. Springfree does the same job with composite rods under the mat. Both designs are trying to remove the same hazard, and our 30% enclosure-and-edge metric rewards both.

The Ultra keeps coil springs, but does not leave them inside the play area: Vuly states the springs sit outside the netting and that the net and springs arch in opposite directions, so a fall lands on the mat or the net rather than the coils or the frame. It also publishes a detail most makers leave out, that the springs are two-layered and 20% wider than the nearest competitor's, which is a bounce claim rather than a safety one. If you want the whole argument for and against removing springs, it is on Springfree vs spring trampolines.

The zero-gap net and the door that closes itself

The net-to-mat junction is the one thing we look at first on every trampoline, because a gap there is where a foot goes through onto the springs. Vuly publishes a measured claim rather than an adjective: a 0 in gap between mat and net, stated on the Thunder page under 220 lb of static weight, and "strong, no-gap netting" with the same zero-inch figure on the Ultra. On both, the enclosure stands 15 in taller than the nearest competitor's by Vuly's own comparison, and on the Thunder the poles curve away from an hourglass-shaped enclosure so a jumper pushed sideways meets net, not pole.

The door is the part we would actually pay for. Vuly's entry seals shut behind the jumper with no zip and no Velcro on both models. Zips get left open; that is how a four-year-old walks off a trampoline. Net design across the whole field is compared on best trampolines with an enclosure net. What Vuly does not publish is the thickness of the skirt or pad at the edge, or the mesh gauge of the net, so the Thunder scores a 9 on enclosure rather than a 10, and the Ultra an 8, because the Ultra page does not state whether its poles curve.

330 lb, next to 1,650 lb

Vuly does the thing we keep asking makers to do: it prints two numbers and labels them. Maximum user weight is 330 lb (150 kg) on both the Thunder and the Ultra, and both are separately certified to withstand 1,650 lb of static weight. The 330 lb figure is the one that governs whether a parent can use it; the 1,650 lb figure is a test load, not an invitation to put five children on the mat. Vuly's own manual is explicit on that point: do not allow more than one person on the trampoline.

For context, 330 lb is higher than Skywalker's published 275 lb and Springfree's 220 lb, and level with the highest per-jumper figures in the round-frame class. If you are buying a trampoline an adult will use as well as the children, that number is the reason to look at Vuly. The full explanation of why headline capacity figures mislead is on how much weight a trampoline can hold.

AS4989 and EN 71, not ASTM F381-16

Vuly certifies to AS4989:2015, the Australian trampoline standard, and to EN71-1:2014, EN71-2:2011+A1 and EN71-14:2014 in Europe, with accreditation stated from TUV and Intertek. That is more specific than the generic "ASTM certified" line most listings carry, and independent third-party accreditation is worth something. What is missing is the US trampoline standard by designation. ASTM F381-16 covers components, assembly, use and enclosures for home trampolines, and it is the standard a US buyer can check a claim against. Vuly's US pages do not name it, and the US owner's manuals we read do not either.

That is why certification scores an 8 here and not a 9. It is not a safety failing so much as a documentation gap for this market: AS4989 and EN 71 are real standards with real test regimes, they are just not the ones a US parent, or a US insurer, will recognize. Zupapa and Jumpzylla name ASTM; Vuly names AS4989. Our weighting for that judgment is published on how we rate.

The anchoring gap

Nothing in a Vuly box holds the trampoline to the ground. The US manuals for both the Thunder and the Ultra raise the risk and then stop short of a method: they warn that the trampoline can tip over or blow away and say sandbags or pegs may be suitable anchorage devices. There is no anchor pattern, no stated pull rating and no kit. On our rubric that is a 5 out of 10 for anchoring, against a 9 for the brands that put wind stakes in the carton.

This is fixable for the cost of a kit, and it is not optional: a 14 ft trampoline is a sail. Order an anchor kit with the trampoline from best trampoline anchors, and put it in before the first jump using how to anchor a trampoline. While you are measuring, note that Vuly asks for a minimum of 2 m of clearance on every side and the manual asks for 27 ft of overhead clearance, which rules out siting one under a tree line.

The Junior and the under-6 line

The Junior is the only Vuly built for the age group CPSC tells you to keep off a full-size trampoline. It is 6.56 ft across with a 3.94 ft mat and a 5.09 ft net, and the number that matters is the mat height: 1.48 ft, about 17.8 in off the ground. Vuly's own manual attaches its under-6 warning to trampolines over 20 in tall, so the Junior sits below the line its maker draws. Warranty is unusually good for the size, with 3 years on the coil springs and fiberglass net poles.

Two honest caveats. Vuly publishes no maximum user weight for the Junior anywhere on the US page, and it does not describe how the net attaches to the mat on this model, which is why it scores 5.5 against the Thunder's 7.9. And the American Academy of Pediatrics discourages home trampoline use for children generally, not just full-size frames. Read trampoline age recommendations before you buy for a preschooler, and are trampolines safe for kids if you have not already.

Who Vuly is wrong for

Anyone who needs the US standard named on the box, for a homeowners policy or their own peace of mind: Zupapa, Jumpzylla and Skywalker all name ASTM. Anyone buying the cheapest trampoline that clears the safety bar, because Vuly sits at the premium end of both its spring and springless lines. Anyone who wants a long warranty on the parts that wear first, since the net and poles are covered for a year here against 2 at Zupapa and 10 on every part at Springfree. Anyone who will not buy an anchor kit separately. And per CPSC, anyone whose jumper is under 6 and is looking at a full-size frame rather than the Junior.

Alternatives, side by side

Springfree is the direct springless comparison: rods instead of leaf springs, 10 years on every part, and a 220 lb single-jumper limit that is 110 lb below Vuly's. Zupapa is the direct value comparison: a sewn no-gap net, foam-wrapped curved poles, wind stakes in the box and ASTM named, without Vuly's published static rating or its certified accreditation. The whole field sits on best trampolines.

What to check on a Vuly listing

• Which generation is it? Match the published overall diameter and mat size, not the model name.
• Thunder or Ultra: leaf springs under the mat, or coil springs outside the net?
• Does the listing repeat the 330 lb maximum user weight, or only the 1,650 lb static figure?
• Which warranty split applies: 10 years on the frame (Thunder) or 5 (Ultra)?
• Add an anchor kit to the same order; nothing in the box holds it down.
• Do you have 2 m of clearance on all four sides and 27 ft overhead?
• Is the entry the self-sealing door, or has a reseller substituted a zip enclosure?
