1. Origin Hybrid (best for heavier bodies overall)
Firmness: Medium-Firm
Price: From $503 (Queen $711 on sale)
Support core: 7-zone ErgoCoil™ pocket springs
Edge support: Reinforced
Trial period: 120 Nights
Warranty: 15 Years
Check Deal
The Origin Hybrid is the mattress we recommend first for heavier sleepers because it holds up. The 7-zone ErgoCoil™ pocket-spring core firms up under the hips and lumbar — exactly where higher body weight loads a mattress — so you stay supported on top rather than sinking into a hammock.
The perimeter is reinforced, so the edges don’t collapse when you sit to put your shoes on or sleep near the side. Above the coils, CertiPUR-US® certified foams add pressure relief without the quick softening that catches out cheap all-foam beds.
Its 15-year warranty is the longest here and a real signal of durability, and the 120-night trial gives you time to confirm it holds its shape under your weight.
Pick if...
You want the most durable all-round support: a firm zoned coil core, reinforced edges and the longest warranty on this list.
Pros
- Firm zoned pocket-spring core: deep support under the hips where heavier bodies load the bed
- Reinforced edges: the perimeter holds up for sitting and edge sleeping
- 15-year warranty: the longest here and a genuine durability signal
- Certified, breathable build: CertiPUR-US® foams over a ventilating coil layer
Cons
- One firmness only: very heavy stomach sleepers may still want a firmer custom build
- Heavy to move: a 37 kg queen is a two-person job to rotate
- Mixed after-sales reports: a minority of owners describe slow warranty handling

2. Sleeping Duck MACH II (best customisable and firmest edges)
.jpeg)
Firmness: Customisable — order it Firm
Price: From $999 (RRP up to $1,649)
Support core: Adaptive microcoil pocket-spring hybrid
Edge support: Excellent
Trial period: 100 Nights
Warranty: 10 Years
For heavier sleepers who’ve been let down by fixed-firmness beds, the Sleeping Duck MACH II is the smart buy. You choose the firmness at home by swapping the comfort layer — order it Firm for the most support — and couples can order split firmness so a heavier and lighter partner each get the right feel on one bed.
The individually pocketed microcoils resist sagging better than connected innersprings, and the edge support is among the strongest we’ve tested — you get the full sleep surface right to the perimeter. If your weight changes, you can re-tune the firmness instead of replacing the mattress.
It sits in the premium tier and the trial is 100 nights rather than 120, but for adaptable, durable support under higher body weight it’s hard to beat.
Pick if...
You want to dial in a firm feel, get the strongest edges here, or split the firmness with a partner of a different weight.
Pros
- Order it Firm: swap the comfort layer at home for maximum support
- Split firmness for couples: a heavier and lighter partner each get the right feel
- Strong edge support: use the full width of the bed right to the perimeter
- Durable microcoil core: pocketed coils resist sagging under higher weight
Cons
- Premium pricing: costs more than the value hybrids
- Shorter trial: 100 nights versus 120 on the Origin and Newentor
- Firmness swap takes effort: re-zipping the comfort layer is a small job
| Key spec | Detail |
|---|---|
| Construction | Adaptive microcoil pocket springs with a swappable foam comfort layer |
| Firmness | Customisable — Soft, Medium or Firm; split firmness available |
| Edge support | Excellent — among the strongest we’ve tested |
| Trial / Warranty | 100 nights / 10 years |
| Price | From $999 (RRP up to $1,649 in larger sizes) |

3. Ergoflex 5G (best high-density memory foam)
Firmness: Firm memory foam
Price: From $949.99 (RRP $999.99)
Support core: High-density visco-elastic memory foam
Trial period: 30 Nights
Warranty: 10 Years
Check Deal
If you want memory foam rather than springs, density is everything for a heavier body — and the Ergoflex 5G is built around a high-density visco-elastic core that resists the quick sagging that ruins cheap foam beds under weight.
It’s a genuinely firm, supportive foam feel with strong pressure relief for the hips and shoulders, and the dense core keeps you supported on top instead of letting you sink through. The cover is removable and washable, and Ergoflex backs it with a 10-year warranty.
The trade-offs: memory foam runs warmer than a pocket-spring hybrid, and the comfort trial is a shorter 30 nights, so be sure firm foam is what you want before ordering.
Pick if...
You prefer a firm, high-density memory foam feel over springs and want proven durability under weight.
Pros
- High-density memory foam core: resists sagging under higher body weight
- Genuinely firm, supportive feel: keeps you on top of the bed, not sunk into it
- Removable, washable cover: easy to keep clean
- 10-year warranty: strong durability cover for a foam mattress
Cons
- Runs warmer: memory foam traps more heat than a pocket-spring hybrid
- Shorter trial: 30 nights versus 100 to 120 on the hybrids here
- Foam feel isn’t for everyone: spring fans should choose the Origin or Sleeping Duck
| Key spec | Detail |
|---|---|
| Construction | High-density visco-elastic memory foam with a removable washable cover |
| Firmness | Firm |
| Trial / Warranty | 30 nights / 10 years |

4. Newentor Hybrid (best value)
Firmness: Medium-Firm (6/10)
Price: From $388.50 (Queen $598.50 on sale)
Support core: 7-zone pocket springs
Edge support: Reinforced
Trial period: 120 Nights
Warranty: 10 Years
Check Deal
You don’t have to spend big for real support. The Newentor Hybrid is a genuine 7-zone pocket-spring hybrid with reinforced edges and a supportive medium-firm feel — the core ingredients a heavier sleeper needs — usually for under $600 in queen.
The individually wrapped coils hold their shape better than connected innersprings, the foams are CertiPUR-US® certified and the cover carries OEKO-TEX® Standard 100. It’s not as plush or as customisable as the premium picks, but for the money the support is excellent.
With a 120-night trial and a 10-year warranty, it’s the value choice for heavier bodies by a distance.
Pick if...
You want firm, reinforced pocket-spring support on a budget.
Pros
- Firm 7-zone pocket springs: real coil support, not a foam core
- Reinforced edges: holds the perimeter better than budget foam beds
- Double-certified: CertiPUR-US® foams and an OEKO-TEX® cover
- Under $600 in queen: the best support per dollar here
Cons
- Cover isn’t removable: pair it with a washable protector
- Leaner local support: some buyers report slower after-sales service
- Stock gaps: popular sizes periodically drop to pre-order
| Size | Dimensions (W×L×H) | Price |
|---|---|---|
| King Single | 107 × 203 × 25 cm | $504.45 |
| Double | 137 × 188 × 25 cm | $547.20 |

Price: From $1,649

It’s a premium purchase with longer delivery times since each bed is made to order — treat it as the upgrade pick. Confirm current trial and delivery terms before you commit.

6. Koala mattress (popular all-foam pick)
Firmness: Flippable — Medium-Firm or Firm
Price: From $890
Support core: Kloudcell® foam
Trial period: 120 Nights
Warranty: Up to 10 Years
Rating: ★★★★★ (4.7/5)
Australia’s most recognisable mattress earns a mention. The Koala mattress uses Kloudcell® foam with a flippable comfort layer that switches between medium-firm and firm, and its motion isolation is excellent.
For heavier sleepers specifically, though, it sits last. It’s an all-foam bed, and foam softens and loses edge support under higher body weight sooner than a pocket-spring hybrid. If you’re over about 100 kg, the firm hybrids above will hold their shape longer.
Pros
- Flippable firmness layer: switch between medium-firm and firm at home
- Excellent motion isolation: good for couples
- Kloudcell® open-cell foam: breathes better than traditional memory foam
- 120-night trial: with fast metro delivery
Cons
- All-foam core: softens and loses edge support under higher weight sooner than a hybrid
- Weaker edges: less perimeter support than the pocket-spring picks above
- Price has crept up: from $890 against better-supported hybrid competition
| Size | Dimensions (W×L×H) | Price |
|---|---|---|
| King Single | 107 × 203 × 25 cm | $990 |
| Double | 138 × 188 × 25 cm | $1,150 |
| Queen | 153 × 203 × 25 cm | $1,249 |
| King | 183 × 203 × 25 cm | $1,490 |
From $890 · 120-night trial · up to 10-year warranty · flippable medium-firm/firm layer. Prices checked July 2026 and include current promotions where noted — always confirm on the brand site.
How we choose mattresses for heavier bodies
There’s no lab-coat theatre here — just a process we apply the same way to every mattress, whether the brand works with us or not. For higher body weight we weight the criteria differently, so for every mattress on this page we:
- Prioritised support and firmness — firm pocket-spring or high-density foam cores that keep you supported on top rather than sinking through.
- Checked edge support — reinforced perimeters so you can sit and sleep near the edge without the bed collapsing.
- Weighted durability heavily — coil gauge, foam density and warranty length, because higher weight is what exposes a cheap build fastest.
- Aggregated verified owner reviews across ProductReview.com.au, CHOICE and Australian Reddit communities, focusing on long-term sagging reports.
- Scrutinised the fine print — trial length, return logistics and warranty terms.
Sleep Society may earn a commission if you buy through links on this page. That never changes the order of our picks: Koala sits last and carries no links at all, which should tell you how the sausage is made.
Our verdict
For most heavier Australians in 2026, the Origin Hybrid is the best mattress: firm zoned coil support, reinforced edges and a 15-year warranty from $503. Order the Sleeping Duck MACH II Firm if you want to tune the feel or split it with a partner, choose the Ergoflex 5G for high-density memory foam, the Newentor Hybrid to spend less, and the Dusk & Dawn Premiere MK2 if you want it made in Australia.
