Best Mattress For Hot Sleepers Australia 2026

If you wake up kicking off the covers or flipping to the cool side of the pillow, the mattress under you is usually part of the problem. Dense memory foam wraps around your body and holds heat, while the air trapped inside a solid foam core has nowhere to go. The beds that actually sleep cool do the opposite: they move air, wick moisture away from the surface and keep you sleeping on top of the mattress rather than buried in it.

We shortlisted mattresses on how well they manage heat: breathable pocket-spring cores that let air circulate, moisture-wicking covers in TENCEL and bamboo-charcoal, and open-cell foams that breathe instead of baking. Support, trial periods and warranties still had to stack up, because a cool mattress that sags in a year is no bargain, but temperature regulation led every call.

Prices were checked on each brand’s live page in July 2026. Here are the best mattresses for hot sleepers in Australia for 2026.

What is the best mattress for hot sleepers in Australia?

The best mattress for hot sleepers in Australia in 2026 is the Origin Hybrid. Its 7-zone pocket-spring core lets air move straight through the bed instead of trapping it the way a solid foam block does, and the removable TENCEL cover wicks moisture off the surface. You sleep on top of the mattress rather than sinking into a warm hollow, which is exactly what a hot sleeper wants, and it starts from just $503.

For the same cooling recipe at a lower price, the Newentor Hybrid pairs a moisture-wicking bamboo-charcoal cover with a ventilated spring core for under $600 in a queen. Hot couples should look at the Eva Comfort Classic, which adds cooling gel foam and strong motion isolation, and if you prefer foam the adjustable Ecosa uses breathable open-cell foam that sleeps cooler than dense memory foam. The popular Koala mattress rounds out the list, but as an all-foam bed it traps more heat than the hybrids above.

1. Origin Hybrid (best cooling mattress overall)

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

The Origin Hybrid keeps you cool the simplest way there is: it lets air move. Its 7-zone ErgoCoil pocket springs sit under the comfort layer as an open, ventilated core, so body heat escapes down and out through the bed instead of building up in a solid foam slab. For a hot sleeper that airflow is the whole ballgame, and it is why this hybrid tops the list.

The surface is built to run cool too. A removable, machine-washable TENCEL cover wicks moisture off your skin through the night, and the medium-firm HexaGrid layer keeps you resting on top of the mattress rather than sinking into a warm pocket. It starts from $503, with a queen around $729 on Origin’s near-permanent sale, and it carries the longest safety net here at 120 nights and a 15-year warranty.

It only comes in one firmness, so if you want a soft, plush cooling feel you will look elsewhere, and the 37 kg queen is a two-person lift to rotate. But as a bed that keeps you cool and supported year-round, nothing on this list does it better.

Pick if...

You want the coolest all-round mattress: a ventilated spring core and a moisture-wicking cover that keep heat moving away from you all night.

Pros

Pocket springs move air through the bed: the open coil core lets heat escape instead of trapping it like solid foam
Breathable TENCEL cover: the removable cover wicks moisture and stays cool against the skin
You sleep on top, not in it: the medium-firm feel keeps you out of a warm foam hollow
Longest safety net here: 120-night trial and a 15-year warranty

Cons

One firmness only: no plush option if you want a softer cooling feel
Queen climbs toward $729 on sale: pricier than the Newentor once you size up
Heavy to move: a 37 kg queen is a two-person job to rotate

2. Newentor Hybrid (best value cooling pick)

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

The Newentor Hybrid proves you do not have to spend big to sleep cool. Its bamboo-charcoal cover is naturally moisture-wicking, pulling sweat off the surface so it stays drier through a warm night, and underneath sits a 7-zone pocket-spring core that ventilates heat far better than an all-foam bed. A queen regularly sells under $600, which for a cooling spring hybrid is close to unheard of in Australia.

It is properly built for the money. The foams are CertiPUR-US certified under an OEKO-TEX Standard 100 cover, the gel-infused memory foam comfort layer sleeps cooler than plain memory foam, and you still get a 120-night trial and a 10-year warranty. For a hot sleeper on a budget, the cooling-per-dollar here is unmatched.

The trade-offs are honest: the cover does not unzip for washing, so pair it with a breathable protector, and being a smaller brand its local aftercare is leaner than Origin or Eva. For most hot sleepers chasing value, none of that outweighs the price.

3. Eva Comfort Classic (best for hot couples)

Firmness: Medium-Firm
Price: From $1,190
Trial Period: 100 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.4/5)
Check Deal

Eva goes third here, and for hot couples it is the standout. The Comfort Classic layers cooling gel foam and open-cell latex over a pocket-spring core, a combination built to shed heat in Australia’s warm climate, so both sleepers stay cooler than they would on a dense foam bed. The springs add airflow underneath the cooling comfort layers rather than sealing the heat in.

What tips it toward couples is the motion isolation. The layered foam absorbs movement well, so when one hot sleeper rolls over or gets up for a glass of water in the night, the other side of the bed barely moves. Paired with the cooling build, that makes it a strong pick for two people who both run warm and both value undisturbed sleep. It starts from $1,190 with a 100-night trial.

It is the priciest cooling pick here and comes in one medium-firm firmness only, and note the base restrictions: flexi-slat, sprung-slat and adjustable bases void the warranty. On a compatible base, though, it is the cooling bed built for two.

Pick if...

You share the bed and you both run hot: you want cooling gel and latex plus strong motion isolation so neither of you overheats or wakes the other.

Pros

Cooling gel foam and latex: open-cell layers built to shed heat in a warm climate
Pocket springs add airflow: ventilation underneath the cooling comfort layers
Strong motion isolation: hot, restless couples feel less of each other's movement

Cons

Priciest cooling pick here: from $1,190, well above the Origin and Newentor

4. Ecosa Mattress (best cooling all-foam)

Firmness: Adjustable (Plush / Medium / Firm)
Price: From $870 (Queen $1,240)
Trial period: 100 Nights
Warranty: 15 Years
Rating: ★★★★★ (4.7/5)
Check Deal

If you prefer the feel of foam but hate the heat that usually comes with it, the Ecosa is the answer. Its contour foam is open-cell and breathable, so it supports a little like latex while sleeping noticeably cooler than the dense memory foam in cheaper all-foam beds. It is the coolest foam option on this list without stepping up to a spring hybrid.

It is also the most flexible. Unzip the cover and you can reorder the internal layers to switch between Plush, Medium and Firm, so you can dial in your feel without giving up the cool surface. A removable washable cover and a waterproof protector come in the box, and the 15-year warranty is among the longest here, so it is built as a long-term buy.

A queen sits around $1,240, so it is only cheap by mattress standards, and being all-foam it still cannot ventilate heat the way the sprung Origin or Newentor do. But for a foam lover who runs warm, the breathable core and adjustable feel are worth the stretch.

Pick if...

You want the plush feel of foam without the heat: a breathable open-cell core that sleeps cooler than memory foam, with the option to adjust the firmness at home.

Pros

Breathable open-cell contour foam: sleeps cooler than the dense memory foam in cheaper all-foam beds
Adjustable feel: reorder Plush, Medium or Firm without losing the cool surface
Washable cover plus protector: a waterproof protector is included in the box
Long 15-year warranty: among the longest safety nets here

Cons

All-foam, not a hybrid: no spring layer to move air the way the Origin or Newentor do
Priciest fixed pick here: a queen sits at $1,240 before member discounts
Adjusting takes a few minutes: you unzip and reshuffle the layers to change the feel

5. 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 earns a mention, and plenty of hot sleepers search for it by name. The Koala is built on Kloudcell foam under a soft TENCEL cover that is breathable and moisture-managing, with excellent motion isolation, a flippable comfort layer that switches between medium-firm and firm, and a 120-night trial with famously fast metro delivery.

On cooling, though, it lands last. Being an all-foam bed, its core traps more heat than the ventilated pocket-spring hybrids above, and there is no coil layer to let that warmth escape. The TENCEL cover helps at the surface, but the bed simply runs warmer than the Origin or Newentor once you have been on it a few hours. It is a good, popular mattress and a safe brand; it just is not the pick if sleeping cool is your priority.

Pros

Soft TENCEL cover: breathable and moisture-managing against the skin
Excellent motion isolation: good for restless couples
Flippable firmness: switch between medium-firm and firm at home
Fast metro delivery: often same-day in major cities

Cons

All-foam core traps heat: runs warmer than the pocket-spring hybrids above
No spring airflow: the foam core ventilates far less than a hybrid
Price has crept up: from $890 for a bed that sleeps warmer than cheaper hybrids

Size	Dimensions (W×L×H)	Price
Single	92 × 188 × 25 cm	$890
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

How we choose cooling 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 hot sleepers specifically we:

Prioritised airflow — ventilated pocket-spring cores let heat escape, so hybrids that breathe outrank solid foam blocks that trap it.
Checked the cover — moisture-wicking TENCEL and bamboo-charcoal covers pull sweat off the surface and keep the sleeping face drier.
Favoured open-cell foams — where a bed is all-foam, open-cell and gel-infused layers sleep cooler than dense memory foam.
Aggregated verified owner reviews across ProductReview.com.au, CHOICE and Australian Reddit communities, weighting real reports of overheating, 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 coolest, best-value 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 mattress for hot sleepers

1. A breathable, ventilated core

The single biggest driver of a cool night is airflow. A pocket-spring or hybrid core has open channels that let body heat move down and out of the bed, while a solid, dense foam block seals that heat in around you. If you run hot, a ventilated core beats a foam-only one almost every time.

2. A moisture-wicking cover

Heat is only half the problem, sweat is the other half. Covers in TENCEL, bamboo or bamboo-charcoal pull moisture off your skin and let it evaporate, so the surface stays drier and feels cooler. Avoid thick, plush-quilted covers that sit warm against you.

3. Open-cell or gel-infused foam

If you want a foam feel, the type of foam matters. Open-cell and gel-infused foams breathe and disperse heat far better than traditional dense memory foam, which is notorious for holding warmth. It is the difference between a foam bed that sleeps warm and one that sleeps neutral.

4. Support that keeps you on top

The deeper you sink, the more mattress wraps around you and the hotter you sleep. A medium-firm bed that keeps you resting on the surface exposes more of your body to the air, which is why firmer hybrids often sleep cooler than plush, sink-in foam beds.

5. A proper trial period

How a mattress handles heat only shows after a few weeks of real nights, not five minutes in a showroom. A 100-night-plus trial lets you test it through a warm stretch and return it for a refund if it still sleeps hot. Every pick here comes with at least 100 nights.

FAQs

What type of mattress is best for hot sleepers?

A pocket-spring hybrid is usually the coolest choice. Its open coil core lets air move through the bed and carry heat away, which a solid foam block cannot do. That is why our top pick, the Origin Hybrid, and the value Newentor Hybrid both use spring cores. If you prefer foam, look for open-cell or gel-infused layers rather than dense memory foam.

Do memory foam mattresses sleep hot?

Traditional dense memory foam is the worst offender for trapping heat, because it wraps closely around your body and has little airflow. Newer open-cell and gel-infused foams, like the breathable contour foam in the Ecosa, sleep much cooler, but as a rule a foam bed will run warmer than a ventilated spring hybrid.

Does a cooling cover really make a difference?

Yes, at the surface. Moisture-wicking covers in TENCEL or bamboo-charcoal pull sweat off your skin so it can evaporate, which stops that clammy, overheated feeling. A cover alone will not fix a heat-trapping core, but paired with a breathable bed it noticeably improves how cool the surface feels.

What is the best cooling mattress for couples?

The Eva Comfort Classic is our pick for hot couples. It combines cooling gel foam and latex over pocket springs with strong motion isolation, so both partners stay cooler and neither is disturbed when the other moves. The airflow from the springs helps two bodies’ worth of heat escape the bed.

Is a firmer mattress cooler?

Often, yes. A firmer, medium-firm mattress keeps you resting on top of the surface rather than sinking into it, so more of your body is exposed to the air and less is wrapped in warm foam. It is one reason the medium-firm Origin Hybrid sleeps cooler than a plush, sink-in foam bed.
