Plum 12ft x 8ft In-Ground Rectangular Review (2026)

Who the Plum 12ft x 8ft In-Ground Rectangular is for

Homeowners who intend to stay, have a yard that can be dug, and have priced the hole before ordering the trampoline.

Buyers on small or overlooked blocks where a large above-ground trampoline would dominate the yard visually.

Buyers in wind-exposed locations, where an in-ground installation sidesteps the anchoring problem entirely rather than managing it.

Anyone who assumed in-ground meant A$3,000 and stopped looking.

The specification

A 12ft x 8ft rectangular in-ground trampoline with an enclosure and safety net. The footprint is 3.66m x 2.44m and the enclosure stands 1.8m, with roughly 2m of overhead clearance needed on top. Minimum age 6. It arrives in 4 boxes weighing 90kg in total, and the install is about two hours for two adults — once the hole exists.

Maximum user weight 120kg. Hold that number; it is the most important thing on this page and we come back to it below.

Conventionally sprung, with soft PVC safety padding. In-ground changes where the trampoline sits; it does not change what holds the mat up. What Plum have engineered for the installation specifically is the jumping mat — it is vented as well as UV-treated — plus a galvanised steel frame built for in-ground use, a retaining structure to hold back the soil and keep debris out of the pit, and a supplied weather cover.

Safety certification published is EN71-1/2/3/14, the European standards. AS 4989:2015 is not mentioned on the page. Warranty is 12 months.

On price, Amazon is A$200 cheaper than the manufacturer. It is A$649 on Amazon Australia, confirmed 4 August 2026 with the delivery address set to an Australian postcode — listed there as the "Plum 12ft In-Ground Rectangular Trampoline", without the 8ft in the title, so do not think you have landed on a different product. Plum sell the same trampoline on their own storefront for A$849, reduced from a recommended A$1,099. We earn a commission on the Amazon link and nothing on Plum's, so treat that claim with appropriate suspicion and check it — both numbers are above, both are checkable, and it takes half a minute.

The price is the reason this is our in-ground pick rather than a specialist brand. In-ground trampolines in Australia are normally a A$2,000-to-A$3,600 proposition, and that price is why almost nobody has one.

What’s good

It removes the fall-from-height hazard completely. Every other trampoline on this site manages that risk; an in-ground installation eliminates it. That is arguably a larger safety difference than the springless-versus-sprung question that dominates the rest of our roundup.

A$649 changes who this option is available to. At the usual in-ground price the honest advice is "this is the safest installation and you probably cannot afford it". At A$649 it is a real decision.

Wind ceases to be a factor. There is nothing for it to lift, so anchoring becomes unnecessary rather than essential — which partly offsets the excavation cost.

It is close to invisible from the house, which matters more than people admit on a small block or an overlooked one.

The rectangular mat gives an even bounce across the surface rather than returning everyone to the middle.

What’s genuinely bad

It is rated to 120kg, and Plum's own 12ft round — same brand, same A$649 — is rated to 150kg. The direction of that gap is wrong in every way that matters. A rectangular mat returns the highest, most even bounce of any shape, so the loads are greater. It sits flush with the lawn, which is precisely the installation an adult is most likely to step onto for a turn because there is nothing to climb. And dynamic load during a jump is several times static weight, so a 120kg ceiling is not a 120kg person. Check it against the heaviest adult in the house before the excavator arrives, because unlike every other trampoline on this site you cannot change your mind afterwards.

You have to dig a hole, and it has to drain. In clay, rock or established root systems that means an excavator and a contractor, and the installation can easily cost more than the A$649 trampoline. Get that quoted before you order anything — the hole, not the trampoline, decides whether this is affordable.

The warranty is 12 months. On a permanent installation you are paying a contractor to dig for, one year is short — and it is the one figure here that does not reflect the effort the purchase demands.

AS 4989:2015 is not mentioned on the product page. Plum publish EN71-1/2/3/14, the European standards. Genuine certification, not the Australian one.

You must check for underground services before excavating. That is a genuine step, not a formality, and it is not optional.

It is effectively permanent. If you move house, it stays, and you are unlikely to recover its value in the sale price.

In-ground removes the fall hazard but not the spring or padding hazards. An enclosure is still worth having at ground level, and this model is conventionally sprung.

A rectangular mat gives a higher bounce, which suits older children better than toddlers.

AS 4989:2015 safety status

Plum publish "Safety certs: EN71-1/2/3/14" for this model — the European toy safety standards, EN 71-14 being the trampoline one. AS 4989:2015 is not mentioned anywhere on the page, checked 5 August 2026. That is a real certification against a real trampoline standard rather than nothing at all, and it is not evidence of any failure against the Australian standard. It is simply not the Australian standard.

The 120kg maximum user weight is the safety figure that should actually change your decision here, and it deserves to be read alongside the shape. Weight ratings are one of the things AS 4989 governs, and the fact that Plum publish theirs is to their credit. But 120kg on a rectangular mat — the shape engineered to return the most energy — installed at ground level where the barrier to an adult climbing on is zero, is a tighter margin than it looks. Plum's own 12ft round, at the same price, is rated 150kg.

The standard's enclosure and entrapment requirements still apply to an in-ground trampoline. Ground level changes the fall geometry; it does not change the spring pad, the netting or the entry point. Assess those exactly as you would above ground.

On ventilation — the in-ground-specific problem that a general safety standard does not really address — Plum have done the work. A trampoline over a sealed pit is bouncing against trapped air rather than behaving like a trampoline, and the mat here is vented as well as UV-treated. A retaining structure is supplied to hold the soil back and keep the pit clear. Follow their excavation and drainage instructions exactly rather than treating the hole as a hole, because the ventilation only works if the pit does.

Verdict

If you own the home, are staying, can absorb the excavation, and nobody using it is near 120kg, this is the safest way to put a trampoline in an Australian backyard — and at A$649 it is the first time we can say that without also saying it is out of reach. The vented mat, the retaining structure and the in-ground-specific galvanised frame are real engineering rather than an above-ground trampoline sold with a shovel.

That weight rating is the thing to settle first, though, because it is the only decision on this page that a hole in your lawn makes permanent. If an adult over 120kg is going to use it, buy Plum's 12ft round instead — same brand, same A$649, rated to 150kg, and you keep the option of moving it.

Buy it on Amazon. Plum sell the identical trampoline on their own site for A$849 against an RRP of A$1,099, so the A$649 Amazon listing is A$200 cheaper than the manufacturer. We are paid on that link and not on Plum's, which is exactly why we have given you both figures to check.

On BERG, since they are the brand most people find when they search for in-ground: they are a genuine specialist, and their frame protection and ventilation engineering are more developed than anything at this price. But buying one in Australia is awkward. When we checked Amazon Australia on 4 August 2026 with an Australian delivery address set, BERG trampolines showed a single seller offer each — A$1,999 to A$3,630, one with no featured offer at all, one with a single unit in stock — and BERG covers were quoting free international delivery dated February 2027. If you want a BERG, go through an Australian dealer rather than a marketplace listing.
