Best Memory Foam Mattress Australia

Memory foam earned its following for one reason: it moulds to you. Where a firm innerspring pushes back, memory foam sinks in around the hips and shoulders, cradling pressure points and soaking up movement so a restless partner barely registers on the other side of the bed. If you want that deep, contouring, motion-killing feel, this is the list for you.

A quick word of honesty up front. Most beds marketed as the ‘best memory foam’ are all-foam slabs, but the mattress we rate highest overall is actually a hybrid that leads with memory-foam comfort layers over springs. We explain exactly why below, and for anyone who wants classic, pure all-foam memory foam we point you straight to the Ergoflex 5G. Everything here delivers the memory-foam feel; they just get there in different ways.

Prices were checked on each brand’s live page in July 2026. Where a brand discounts constantly (Emma is the obvious one) we point you to the current sale rather than quote a number that dates within a week. Here are the best memory foam mattresses in Australia for 2026.

Top 3 at a glance

What is the best memory foam mattress in Australia?

The best memory foam mattress in Australia in 2026 is the Origin Hybrid. One honest caveat: the Origin is technically a hybrid, with memory-foam comfort layers over pocket springs, not an all-foam bed. Most beds sold as the ‘best memory foam’ are all flat foam, but we lead with the Origin because its comfort layers are memory foam, it is superbly designed and one of the most affordable options here, and the springs add support and airflow that all-foam beds lack.

If you want classic, pure all-foam memory foam, the Ergoflex 5G is the pick: dense, orthopedic and genuinely TEMPUR-like, with the deep contouring hug purists want. For the same memory-foam feel at the lowest price, the Newentor Hybrid pairs gel-infused memory foam with 7-zone springs for under $600 in a queen. The famous Koala mattress rounds out the list, but it lands last: its Kloudcell foam is good, yet it costs more for no extra support.

1. Origin Hybrid (best memory-foam mattress overall)

Firmness: Medium-Firm
Price: From $503 (Queen ~$729 on sale)
Trial period: 120 Nights
Warranty: 15 Years
Rating: ★★★★★ (4.6/5)

The Origin Hybrid tops this list even though it is not a pure memory-foam bed, and we want to be upfront about that. It leads with memory-foam comfort layers for the contouring, pressure-relieving feel this list is all about, then sits them over 7-zone pocket springs. The result is the deep cradle of memory foam without the swampy, sink-and-stay sensation an all-foam bed can give you.

That spring core is the reason it beats the flat-foam beds overall. Memory foam alone traps heat and offers little rebound; the pocket springs add airflow so it sleeps cooler, and they keep your spine level rather than letting heavier hips sag. It is also one of the most affordable beds here, from $503, with a removable machine-washable TENCEL cover and the longest safety nets on the list.

If you are set on classic all-foam memory foam, the Ergoflex 5G at number three is your bed. But for most people who simply want that memory-foam feel done well, the Origin’s mix of contouring comfort, cooler springs and a 15-year warranty makes it the smartest overall buy.

Pick if...

You want the contouring, pressure-relieving feel of memory foam but with cooler, more supportive springs underneath, and a washable cover and long warranty.

2. Newentor Hybrid (best value memory-foam feel)

Firmness: Medium-Firm (6/10)
Price: From $388.50 (Queen $598.50)
Trial period: 120 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.4/5)

The Newentor Hybrid is how you get the memory-foam feel for the least money. A gel-infused memory foam comfort layer gives you the soft, contouring surface memory foam fans want, and it sits over a 7-zone pocket-spring core, so like the Origin it pairs that cushioned feel with real support. A queen regularly sells under $600, which for this build is close to unheard of in Australia.

The gel infusion matters here: plain memory foam runs hot, and gel plus the bamboo-charcoal cover helps pull that heat away. The foams are CertiPUR-US certified under an OEKO-TEX Standard 100 cover, which is unusually thorough at this price, and you get a 120-night trial and 10-year warranty to back it.

The compromises are minor and honest: the cover does not unzip for washing, so pair it with a protector, and local aftercare is leaner than the big names. If you want the deepest all-foam hug the springs will feel a touch bouncy, in which case the Ergoflex is your bed, but for memory-foam feel per dollar nothing here beats it.

Pick if...

You want the contouring, motion-isolating feel of memory foam at the lowest possible price, and a queen under $600 sounds too good to pass up.

3. Ergoflex 5G (best pure memory-foam)

Firmness: Medium-Firm
Price: From $949.99
Trial Period: 30 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.2/5)
Check Deal

If you clicked on this list wanting real, classic memory foam, the Ergoflex 5G is your mattress. It is the only true all-memory-foam bed on this list: a dense, 5-layer, 23 cm slab of high-density foam that delivers the slow, moulding, TEMPUR-like hug that made memory foam famous. You do not lie on this bed so much as settle into it.

That density is what sets it apart for pressure relief and motion isolation. The foam flows around hips and shoulders to unload pressure points, and it absorbs movement so completely that a restless partner is barely felt. It has earned over 3,000 five-star reviews and endorsements from Australian back specialists, and it is backed by a 10-year warranty on a design that has been refined for years.

The trade-offs are the classic memory-foam ones. The trial is just 30 nights, the shortest here, dense foam sleeps warmer than the spring hybrids above, and there is a single firmness with a deep sink that not everyone loves. But if the pure memory-foam feel is the whole point, this is the pick.

Pick if...

You want genuine, classic all-foam memory foam: a deep, orthopedic, TEMPUR-like hug with class-leading pressure relief and motion isolation.

4. Onebed Original (best adjustable memory foam)

Firmness: Adjustable (Medium, Medium-Firm, Firm)
Price: $1,050
Trial Period: 125 Nights
Warranty: 15 Years
Rating: ★★★★★ (4.4/5)
Check Deal

The Onebed Original is the memory-foam bed for people who are not sure how much memory foam they want. Its top comfort layer is swappable: run the memory-foam side up for the classic slow, contouring feel, or flip to the latex layer for a springier, cooler surface. It is effectively two feels in one bed, which takes the gamble out of buying memory foam unseen.

Underneath the flexibility it is a well-made all-foam bed with CertiPUR-US certified foams, and it is backed by a 125-night trial and a 15-year warranty, both generous for an all-foam mattress. If the deep memory-foam hug turns out to sleep too warm or too soft for you, you simply swap the layer rather than return the bed.

It is not the cheapest way to get a memory-foam feel, at $1,050, and the memory-foam side runs warm like any dense foam. Changing the feel also means unzipping the cover and re-stacking layers, so it is a deliberate job rather than an instant switch. But for keeping your options open, nothing else here matches it.

Pick if...

You want the memory-foam feel but the option to dial it back to latex at home, without gambling on one fixed surface.

5. Emma Comfort (best big-brand memory-foam hybrid)

Firmness: Medium-Soft
Price: From $559 (current sale)
Trial period: 150 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.8/5)

The Emma Comfort is the safe, big-brand way to get a memory-foam feel. It stacks three foam comfort layers over pocket springs, so you get the soft, contouring surface and the excellent motion isolation memory foam is prized for, with springs adding support underneath. It is Australia’s most awarded mattress, a repeat ProductReview.com.au winner with thousands of five-star ratings.

That foam-over-spring build makes it a genuine couples’ bed: the layers soak up movement so you barely feel a partner shift, and the medium-soft feel suits sleepers who want to sink in rather than perch on top. You also get the longest trial on this list at 150 nights, so there is plenty of time to be sure before Emma’s next sale ends.

The catches are the feel and the pricing. At around 6.7/10 it is on the softer side, so committed back and stomach sleepers may want the firmer Origin, and because Emma discounts so aggressively the price swings with each sale. A queen frequently drops near $559, so always check the current deal rather than assume RRP.

Pick if...

You want a big-brand, heavily reviewed memory-foam hybrid with a soft, motion-isolating feel and a long trial, timed to one of Emma’s frequent sales.

6. Koala mattress (popular pick)

Firmness: Flippable (Medium-Firm / Firm)
Price: From $890
Trial period: 120 Nights
Warranty: Up to 10 Years
Rating: ★★★★★ (4.7/5)

Australia’s most recognisable mattress deserves a mention, and plenty of memory-foam shoppers search for it by name. The Koala is built on Kloudcell foam under a soft TENCEL cover, with excellent motion isolation, a flippable comfort layer that switches between medium-firm and firm, a 120-night trial and famously fast metro delivery.

On the memory-foam brief, though, it lands last. Kloudcell is a responsive foam rather than the slow, deep-sinking memory foam of the Ergoflex, so if it is that classic hug you are chasing this is not quite it. And from around $890 it costs more than the Newentor and sale-priced Emma while giving you no extra support to show for it: being all-foam, it lacks the zoned spring support the hybrids above use to keep heavier bodies level. It is a good mattress and a safe brand; it is just not the best pick on this particular list.

How we choose memory foam mattresses

There is no lab-coat theatre here, just the same process applied to every mattress whether the brand works with us or not. For memory-foam beds specifically we:

• Judged the foam feel and quality — whether the comfort layer delivers genuine slow, contouring memory foam or a cheaper, faster foam pretending to be it.
• Tested pressure relief and motion isolation — the two things memory foam is bought for, at the hips, shoulders and across a shared bed.
• Checked heat and support — dense foam can trap heat and let heavier bodies sag, so we favoured beds that manage temperature and keep the spine level.
• Aggregated verified owner reviews across ProductReview.com.au, CHOICE and Australian Reddit communities, and re-checked those scores at this update.
• Confirmed live pricing — every price was checked on the brand’s own page in July 2026, and where a brand discounts constantly we tell you to check the current sale.

Sleep Society may earn a commission if you buy through links on this page. That never changes the order: the best memory-foam bed leads and Koala sits last with no link at all, which should tell you how the sausage is made.

What to look for in a memory foam mattress

1. Genuine memory foam, not just any foam

The whole point of memory foam is the slow, moulding response that cradles pressure points. Cheaper beds use a fast-rebound foam that looks similar on a spec sheet but feels flat. Look for high-density memory foam, and for the deepest classic hug an all-foam bed like the Ergoflex, or a hybrid that genuinely leads with memory-foam comfort layers.

2. Heat management

Dense memory foam is the material most likely to sleep hot, because it wraps around you and traps body heat. Gel infusions, open-cell foams, breathable covers and, in a hybrid, a pocket-spring core all help pull that heat away. If you sleep warm, weight this heavily.

3. Support underneath the comfort

Soft memory foam on top still needs a firm base to keep your spine level, otherwise heavier hips sink too far. A high-density support core or, in a hybrid, zoned pocket springs stops the contouring feel from turning into a sag.

4. A proper trial period

Memory foam feels different after a fortnight than in the first five minutes, and the deep-sink feel is divisive. A 100-night-plus trial is your insurance policy so you can return it if the hug is not for you. Note that the Ergoflex, at 30 nights, is the exception on this list.

5. A warranty that means something

Body impressions, where a permanent groove forms in the foam, are the most common way a memory-foam bed fails. A 10-year-plus warranty signals the maker expects the foam to hold its shape, and gives you recourse if a dip forms. Check what depth of sag the warranty actually covers.

FAQs

What is the best memory foam mattress in Australia?

Overall we rate the Origin Hybrid, which leads with memory-foam comfort layers for contouring pressure relief but adds pocket springs for cooler, more even support. If you want a pure all-foam memory-foam bed, the Ergoflex 5G is the classic-hug pick, and the Newentor Hybrid delivers the memory-foam feel for the lowest price.

Is a memory foam or hybrid mattress better?

It depends on the feel you want. Pure memory foam like the Ergoflex gives the deepest, slowest, most enveloping hug and the best motion isolation. A hybrid like the Origin or Emma keeps the contouring memory-foam surface but adds springs for more airflow and support, which suits most sleepers and heavier bodies better. Neither is universally ‘better’.

Do memory foam mattresses sleep hot?

They can. Dense memory foam wraps around you and traps body heat more than a springy bed does. Modern designs fight this with gel infusions, open-cell foams and breathable covers, and hybrids add a pocket-spring core for airflow. If you run warm, a gel-infused or hybrid option like the Newentor or Origin is a safer bet than a plain all-foam slab.

Is memory foam good for back pain?

It can be, because it distributes weight and keeps pressure off the joints, and the Ergoflex in particular is endorsed by Australian back specialists. The key is enough support underneath: a memory-foam comfort layer over a firm core or springs keeps your spine neutral, whereas soft foam with no support can let the back sag. Buy for support, not just softness.

How long do memory foam mattresses last?

A good one lasts eight to ten years or more. Durability comes down to foam density and quality, which is why we weight warranty length and real-world body-impression reports heavily. Every bed here carries at least a 10-year warranty, and several stretch to 15, so they are built to hold their shape rather than groove within a year.
