Do you wake up drenched in sweat or toss and turn at night, constantly flipping your pillow to the cool side? A restful night’s sleep often depends on creating the right environment. For many, staying cool is key.
Whether you’re prone to overheating, share a bed with a partner who piles on blankets, experience hot flushes, or sleep in a bedroom that feels like a glasshouse, a cooling mattress could be the solution to your sleepless nights.
Sleep Science Manager Emma Merrit from German mattress brand Emma explains to the Australian Women’s Weekly that “decreasing our core body temperature is a prerequisite for increasing the production of melatonin,” which is why sleeping in the summer heat can feel impossible.
While most modern mattresses feature breathable outer layers, cooling mattresses take innovation to the next level. Their structures are designed to promote airflow, and many feature gel cooling technology to regulate your body temperature and prevent overheating.
To help you beat the heat, we’ve rounded up the best cooling mattresses available in New Zealand. Our top tip? Pair your new mattress with a cooling topper and breathable sheets for even sweeter dreams.

2026’s best cooling mattresses NZ
CoolComfort Mattress
From $1,330 (usually $1,900) at Ecosa
Best for: Hot, sweaty sleepers seeking a good night’s sleep
The CoolComfort Mattress is designed to keep you cool and comfortable all night. Its seven-layer construction includes innovative features like breathable grid cushioning and copper and graphene-infused foam to draw heat away from the body. Topping it off is a machine-washable cover made from a cooling polymer blend that feels noticeably cool to the touch – up to 80% cooler than standard mattress surfaces.
Don’t just take our word for it – our Commercial Editor Sarah Templeton reviewed the Ecosa CoolComfort Mattress last summer, saying:
“through my thin fitted sheet, I can feel the cooling mattress, even during some of the hottest nights of the year thus far. I am sweating less during the night, and the breathability of the mattress is noticeable.”
The Ecosa CoolComfort Mattress also gets bonus points for its flexible grid cushioning and pocket springs, which deliver the contouring comfort of memory foam while providing excellent back support – vital if you’re sharing the bed with a partner and need zero-disturbance sleep. Lastly, to enhance your sweat-free slumber, add on the Ecosa Cooling Pillow and the TempRite Quilt for added chill.

Hybrid Mattress
From $799 at Peace Lily
Best for: Sustainably-minded shoppers after a hypoallergenic, temperature-regulating mattress that’s safe for their family
Peace Lily’s hybrid mattress combines an organic cotton cover with natural latex featuring a pinhole structure to enhance air circulation, and individually wrapped pocket springs that create open spaces for better airflow. Designed to dissipate heat and moisture, you’ll stay cool throughout the night.
Because latex is naturally antimicrobial and dust mite-resistant, while the organic cotton cover minimises allergen flare-ups, this mattress is an excellent choice for those with sensitivities.
The Peace Lily website recommends placing this mattress on a sturdy bed base to support its weight. To facilitate airflow, slats should be no more than 9cm apart. As with modern mattresses, the Peace Lily Hybrid Mattress offers pressure relief and minimises partner disturbance, with reinforced edge support to prevent roll-off.
Happy customers say the mattress reduces tossing and turning and is cool and comfortable to lie on. Many also appreciate the natural materials that provide their families peace of mind, and note that the mattress has no unpleasant “new mattress smell.” However, because the mattress is on the heavier side, you may need a second person’s help to unbox and position it on your base.
After a cooling mattress without springs? Peace Lily’s Latex Mattress is an excellent eco-friendly alternative, offering breathability, airflow, and temperature.
Sizes: Single, Long Single, King Single, Double, Queen, King, Super King

“This mattress is the perfect combination of features!! The firmness is that sweet spot, it’s not too soft and not too firm. Inflation was super easy and I loved the look right away. The memory foam helps make you feel so well rested but my favourite feature would have to be the zero partner disturbance. My partner moves a lot in his sleep and is always waking me up multiple times a night. Now I don’t have to worry about that and I feel so amazing when I wake up in the morning. Seriously a must have mattress!!!”

Dreamz 5-Zone Cooling Mattress
From $443 at Mighty Ape
Best for: Anyone whose summer sleep is disrupted by heat and a restless partner
If summer nights spent tossing and turning turn a good night’s rest into a distant dream, this mattress tackles both issues head-on. The Dreamz cooling mattress is excellent value because it combines effective temperature control with movement isolation — two major barriers to sleep in warmer months. An ice silk fabric cover and cool-gel-infused memory foam help reduce heat buildup and keep the surface genuinely cool to the touch, so you’re less likely to overheat overnight.
Hiding underneath these cooling layers is an independent pocket spring system with 5-zone support and 6-turn coils. This design improves airflow (helping heat dissipate) and significantly reduces motion transfer, so you’re far less likely to feel a partner turning or shifting during the night.
Multi-point pressure relief adapts to your body’s contours, offering consistent support that promotes proper spinal alignment and reduces pressure points — particularly helpful if you wake with aches in the morning.
It’s reasonably easy to set up, just leave yourself a bit of time. It’s delivered vacuum-packed, so roll it out and allow about 48 hours to fully expand before spread-eagling across.
Sizes: King single, Double, Queen
Firmness: Medium-firm
Key features & benefits:
- Cooling comfort
- Superior motion isolation
- 5-zone ergonomic support
- Reinforced corners
- Formaldehyde-free materials

Do I really need a cooling mattress?
Sophie Lew, Senior Product Marketing Manager at Ecosa, explains that cooling mattresses are becoming increasingly popular, especially among “hot sleepers and those in warmer climates” who are seeking “specialised cooling-technology to improve their nights.”
However, she emphasises that “comfort and firmness remain the most important drivers for our customers, but what that means from one person to the next can change considerably. It all comes down to individual preferences and needs.”
“There is no one-size-fits-all when it comes to sleep,” Sophie adds, highlighting that shoppers are now prioritising “the overall sleep experience and their individual needs,” with a focus on features like “pressure relief, cooling technology, the comfort and firmness that feels right for them, along with long-term durability.”
Do cooling mattresses really work?
If you live in a warmer climate, are prone to overheating or experience night sweats, a cooling mattress can improve sleep quality.
A recent study titled “Sleeping for One Week on a Temperature-Controlled Mattress Cover Improves Sleep and Cardiovascular Recovery,” published in Bioengineering (Basel) in April 2024, found that temperature-regulated mattresses (like the Eight Sleep Pod) can enhance sleep quality. The study highlighted improvements in deep and REM sleep, reduced heart rate, and better recovery. Cooler settings during the night were shown to optimise sleep stages, leaving users feeling more refreshed and comfortable.
Similarly, a 2022 pilot study published in Menopause found that the use of a cooling mattress pad reduced sleep disturbances and hot flash interference in menopausal women. This improved their overall quality of sleep by 52% over eight weeks.
However, it’s still important to take a holistic approach to sleep hygiene beyond your mattress choice. Are you wearing breathable nightwear? Is your bed dressed with cooling sheets and a lightweight duvet? Can you use a cooling fan or air conditioning, or are these options too noisy or energy-wasting? Could you securely leave a window open to let in fresh air?
What type of mattress is the coolest?
In comparison to traditional mattresses, cooling mattresses utilise fabric innovations to offer maximum airflow and moisture-wicking properties.
These innovations may include:
- Latex: Naturally breathable and temperature-regulating, ideal for eco-conscious sleepers.
- Hybrid/Spring: Combines foam layers with pocket springs for airflow and support.
- Cooling Gel Foam: Infused with gel to dissipate heat and keep you cool.
- Breathable Foam – Engineered with open-cell structures or perforations for better airflow.
Many mattresses combine these features and materials, such as latex with springs or cooling gel for enhanced cooling and comfort.
Can I sleep on a cooling mattress during winter?
Yes, many hot sleepers find that a cooling mattress is also suitable for winter use. Its breathability and temperature-regulating properties help maintain a balanced sleep environment by preventing overheating in summer and avoiding excessive heat retention in winter.
If you’re worried about staying warm, pairing your mattress with a cosy duvet or thermal bedding can keep you comfortable and snug during the colder months.
Where can I find a cooling mattress topper?
After an affordable alternative to buying a whole new mattress? Consider a cooling mattress topper or overlay for added breathability and comfort.
