Highlights

  • The cushioning AIRGOCELL foam layer is open-cell, allowing airflow that draws away heat and keeps you cool;
  • The easy-to-remove cover can be removed in seconds, letting you keep your sleeping space clean and fresh with a simple wash;
  • The soft and cradling comfort layers help relieve muscle tension for a more restful sleep.

The Emma Comfort is my best mattress for hot sleepers in Australia due to its cooling technology, generous hug, and fast-acting foam. The best cooling mattresses have technology that helps sleepers feel cool even on hot nights. The technology in the Emma Comfort includes the AIRGOCELL open-cell memory foam, filled with tiny pockets that draw away heat. From my tests, the Emma Comfort had a maximum temperature of 31.7 degrees Celsius, just under the recommended maximum of 32.2 degrees. I felt comfortable and cool with enough airflow that my temperature remained neutral throughout the night. The Emma Comfort is 0.2 degrees cooler than the Ergoflex 5G, which means the Emma Comfort better suits hot sleepers who want slightly stronger cooling power.

The best mattresses for hot sleepers should be cooling as well as pressure-relieving. The Emma Comfort accomplishes this with its thick, cushioning AIRGOCELL and HRX foam layers. From my review, the Emma Comfort had a sinkage of 2.2 inches, which is enough to keep my limbs well-cradled and weight redistribution for excellent pressure relief. This model has 0.15 inches more sinkage than the Koala on its medium-firm side, making the Emma Comfort better suited to hot sleepers who want a more cradling feel.

Another feature I enjoyed regarding the Emma Comfort mattress was its fast-acting memory foam. Sometimes memory foam mattresses have the issue of feeling like ‘quicksand’ when lying in them. The Emma Comfort has a pleasantly opposite feel, ensuring I had continuous ease of movement when switching from my back to my side. According to my review, this model recovered fully from compressions after 0.2 seconds, an almost instantaneous reaction. This is 0.5 seconds faster than the Koala on its medium-firm side, making the Emma Comfort the better option for sleepers who want an unrestrictive, modern memory foam feel.

Based On Our Review

After testing this product, I found the Emma Comfort comfortable on my side. I didn’t experience any tension build-up, and my shoulders and hips were well supported while I remained cool and night sweat-free.

Best Affordable Option - Lazycat Spring Mattress

Highlights

  • The linen cover helps remove heat and moisture, keeping night sweats to a minimum;
  • This model comes at a competitive price, making responsive, cool sleep more affordable;
  • The latex layer naturally doesn’t retain heat, helping keep your temperature neutral while sleeping.

The Lazycat spring mattress is my best affordable option for hot sleepers due to its budget-friendly pricing, cool temperature, and minimal sinkage. The Lazycat is $350 less expensive than the Koala and $899 less expensive than the Peace Lily. Despite the price differences, the Lazycat offers pleasant, cool nights that rival even the Peace Lily’s naturally cool latex.

The Lazycat’s use of a linen cover, gel foam, latex, and coils all contribute to continual heat dispersal and cool nights. Through my tests, I determined it had a surface temperature of 30.4 degrees Celsius after lying on it. I was cool throughout the night, without any heat build-up or discomfort.

The Lazycat is 0.2 degrees warmer than the Peace Lily, which is a small amount. That makes the Lazycat a powerful contender for offering cool sleep, as the latex in the Peace Lily is known to be some of the coolest materials used. The Lazycat is also 1.2 degrees cooler than the Koala. That means the Lazycat is an excellent option for hot sleepers on a budget who want affordable, cool sleep.

Balanced sinkage can also reduce heat retention as your body is less enveloped. In my test, I recorded 1.7-inch compressions with the Lazycat. This created a firmer ‘on’ the bed feel, and I was less wrapped and free to move. This is 0.2 inches less sinkage than the Newentor Hybrid, which makes the Lazycat a better choice for sleepers who want less sinkage, a firmer feel, and less chance of heat getting trapped.

Based on Our Review

As my tests indicate, the Lazycat’s gel-infused foam and latex layers do an excellent job dispersing heat. The breathable cover and coils let me sleep comfortably without waking up to night sweats. I was well supported on my side, and my spine and lumbar were neutral and tension-free.

Highlights

  • The breathable cover and layers are soft to the touch and breathable, helping disperse heat and keep you comfortable;
  • This model comes at a great value, helping sleepers find an affordable and cool place to sleep;
  • Despite its soft top, the edges are extra robust, helping support sleepers who enjoy hugging the edges.

The Origin Hybrid is my best mattress for hot sleepers with restless partners due to its excellent coolness, motion isolation, and durable edge support.

The Origin Hybrid utilises a cool-to-the-touch cover and bamboo memory foam that help wick away heat, making me feel dry, cool, and comfortable during the night. From my tests, the Origin Hybrid had a temperature of 30.5 degrees Celsius. This is similar to the Lazycat, warmer by only 0.1 degrees. That makes both suitable for hot sleepers who want a springy and responsive sleeping surface.

The Origin Hybrid is suitable for couples who experience frequent disturbances from a restless partner. In light of my tests, the Origin Hybrid absorbed motion up to 2.5 inches from my glass of water. I could toss and turn, and my partner wouldn't be disturbed. This is quite impressive, given the use of springy coils in the core of this mattress, and highlights the effectiveness of the Hexagrid top layer.

The Origin Hybrid is 1.5 inches more motion-isolating than the Lazycat, making the Origin Hybrid the better option for restless partners looking for a solution to fewer disturbances at night.

Another feature that I enjoyed regarding the Origin Hybrid is its durable edges. Derived from my tests, the Origin Hybrid compressed at only 2.9 inches when I sat along the edge. It uses a high-density foam edge support, making getting out of bed easier. The Origin Hybrid has better edge support than the Newentor Hybrid at around 0.9 inches. That means the Origin Hybrid is better for hot sleepers who want stability while hugging the edges of their mattress.

Based on Our Review

While testing the Origin Hybrid, I most enjoyed lying on my back with this model. There was a pleasant hug that wasn’t overpowering, and I could freely change my sleeping position. I remained fresh and cool, and the cover felt refreshing whenever I changed my sleeping position.

Highlights

  • The carbon fibre cover is breathable, contributing to an overall cooler sleep;
  • The Gel-Visco Flow memory foam cradles and contours to the body, relieving pressure points;
  • The comfort layers and coils help disperse heat, leading to a temperature-neutral sleep.

The Newentor mattress is my best cool hybrid for hot sleepers due to its cooling cover and coils, pressure relief, and moderate sinkage. All-foam mattresses can sometimes trap heat, but this breathable hybrid won’t have that issue. The Newentor Hybrid uses a breathable cover, gel memory foam, and coils that help circulate and cool the air, keeping your temperature neutral at night. In my tests, I measured a temperature of 30.6 degrees Celsius and remained comfortable and dry despite the summer nights.

This model was 1 degree cooler than the Koala, meaning the Newentor Hybrid is better for hot sleepers who prefer a comfortable hybrid.

Pressure relief is also essential for a good hybrid mattress. The Newentor Hybrid does an excellent job cradling the body with its slow-adaptive Gel-Visco Flw foam layer. Through my tests, I measured a full bounce-back from compressions at 1.1 seconds and noticed a slight delay as the top layers redistributed my weight. I felt moderately ‘weightless,’ buoyant, and relaxed in the top layers.

The Newentor Hybrid had 0.7 seconds slower compressions than the Ergoflex 5G, making the Newentor Hybrid a more suitable option for hot sleepers who want a traditional feel.

A balanced sinkage can also contribute to less heat, as less of the body is enveloped by the layers, which can sometimes hold on to heat. Derived from my tests, I counted a sinkage of 1.9 inches, which left me contoured and cradled without sinking in too deeply. The Newentor Hybrid has 0.2 inches more sinkage than the Lazycat, making the Newntor Hybrid the better option for sleepers who want slightly more sinkage without feeling ‘in’ a mattress.

Based on Our Review

I determined through my tests that the Newentor Hybrid is an excellent solution for hot sleepers. I was pleasantly cool, and didn’t sink too deep in the layers so heat could be trapped. The coils kept me even and straight with the right amount of sinkage and support for effective pressure relief.

Best Flippable Mattress - The Koala Mattress

Highlights

  • It has a memory foam comfort layer on the top that contours the body;
  • The memory foam used in the mattress is dense and firm, providing maximum support;
  • The material used, such as the Lyocell Fibre and open-cell foam, helps regulate air often and keeps the body cool.

The Koala is my best flippable mattress for hot sleepers due to its cool cover, open-cell memory foam, and excellent motion isolation. Beside the fact that the comfort layer can be flipped to balance out the firmness, it can let air run through the TENCEL™ Lyocell Fibre cover on the top and the open-cell Kloudcell™ foam in the bottom layer and constantly cool your body down during sleep. During my tests, the Koala mattress was cooler by 0.1 degrees than the Emma Comfort, making both feel similar in coolness.

The memory foam on this one is top notch when it comes to reducing motion transfer. When you jump on one side, having a glass of water on the other side, it’s as if you never jumped at all. That is why partners will love this one. Overall, it’s a supportive, adjustable, and balanced-out mattress that keeps you fresh all night.

Motion transfer of the Koala Mattress

The Koala performed very well in terms of better motion isolation compared to other models during my review. The Koala’s medium-firm side absorbed motion 6 inches further away than the Peace Lily mattress. That means it can isolate more significant motions, like tossing and turning, from a partner.

Based on Our Review

I tested this mattress with a blanket over myself, and still I did not sweat or feel hot even once. It just kept the air flowing from underneath all night.

Why You Should Trust Me

Before I came up with the list you see in this article, I tested a large number of mattresses that I thought would suit hot sleepers. While testing them, I considered the material, cooling features, firmness level, etc. to determine whether the mattress can properly cool the body down and regulate air. I closely followed my testing methodologies, and once I ranked the mattresses, I chose these 5 as the best final options for you to make a better decision before purchasing.

How to Buy A Mattress For Hot Sleepers

When a consumer is on the hunt for a cooling mattress, there are many factors to consider.

Some vital considerations include material type, firmness level, cooling features, pressure relief, and price point.

Material Type

One of the most important considerations when shopping for a new mattress is the type of material. Many mattresses are made from memory foam, which conforms to the body's shape and provides excellent support. 

However, memory foam can retain heat, so it's important to look for a mattress with special cooling features if one tends to sleep hot. Other popular mattress materials include latex and coils, which provide excellent support and firmness.

In my expert opinion, hybrid mattresses provide excellent features that will appeal to lovers of memory foam and innerspring mattresses.

Firmness Level 

Another key consideration is the firmness level. Some hot sleepers may prefer a firmer surface that allows them to sink in a little bit, while others may prefer a softer surface that provides more cushioning. 

There is no right or wrong answer regarding firmness, so the sleeper needs to choose the level that feels most comfortable for them.

I think opting for a medium-firm bed is the best balance between a soft and firm mattress; this way, you get the best of both worlds.

Cooling Features 

When it comes to finding the best mattress for hot sleepers, cooling features are important. Many mattresses now come with built-in cooling technologies, such as gel-infused memory foam or special cooling fabric. 

These features help to wick away moisture and keep the sleeper cool throughout the night.

Another important factor to keep in mind is the material used for the cover. Some mattress covers, such as cotton or bamboo, are naturally cooling and can help to regulate body temperature.

Budget

The best mattresses are not always the most expensive ones, but the consumer must find one that fits within their budget.

For example, while the best mattresses can offer exceptional comfort and support, they may still be a little higher in cost than an average mattress.

Pressure Relief

Exceptional pressure relief is ideal for those who sleep hot, turn and toss when they sleep. 

A mattress should be firm enough to provide optimal support but "soft enough" to allow the sleeper's body to sink in. This will help minimize tossing and turning to get the best night's sleep possible.

A good mattress should also be responsive, meaning it moulds around the body and reduces pressure points. 

Latex mattresses are the perfect choice for individuals looking for an eco-friendly mattress with greater bounce and a quicker response time.

Conversely, memory foam is preferable for those who desire a slower bounce rate, deep compression support, and motion isolation when sleeping.

Ideal Sleep Environment For Hot Sleepers

In addition to finding the right mattress, hot sleepers can do a few other things to create the ideal sleep environment. Some simple tips include:

  • Investing in a quality air conditioning unit or fan to keep the room cool and dry
  • Dressing in lightweight, breathable fabrics such as cotton or linen
  • Avoiding foods and drinks that may induce night sweats, such as spicy foods or caffeinated beverages

F.A.Q.

What is the best type of mattress for hot sleepers?

The best type of mattress for hot sleepers is specifically designed to help regulate body temperature and provide optimal support for the sleeper. This may include features like a cooling system or gel-infused memory foam.

What type of mattress does not get hot?

Latex foam mattresses tend to be less prone to heat retention, as they are highly breathable and made of natural materials. 

Some memory foam mattresses feature cooling gel or other temperature-regulating technologies that help keep the mattress from getting too hot.

Summary

With these considerations in mind, one can be sure to find the cooling mattress that meets his/her needs and budget. 

By creating a cool and comfortable sleep environment, hot sleepers can enjoy a good night's sleep without worrying about waking up sweaty or uncomfortable. 

In my opinion, the Emma Comfort is my best mattress for hot sleepers, thanks to its great open-cell foam for coolness, pressure-relieving hug, and responsive foam. From my tests, I was exceptionally comfortable on my side, never experiencing any tension or heat build-up. This model best suits hot sleepers who want a mattress that is easy to move around on and doesn’t make you feel ‘stuck’ in the layers.

  1. Are there any special care instructions for maintaining cooling mattresses?

    1. While care instructions can vary by brand and mattress type, here are some general tips for maintaining cooling mattresses:

      • Use a mattress protector to keep your mattress clean and free from spills.
      • Rotate or flip the mattress (if it’s a double-sided design) regularly to ensure even wear.
      • Follow the manufacturer’s cleaning recommendations, which may include spot cleaning with a mild detergent.
      • Keep the mattress well-ventilated by not covering it with heavy blankets or sheets.
      • Avoid exposing the mattress to direct sunlight for extended periods, as this can affect materials.
  2. What’s the main difference between gel-infused and latex mattresses in terms of cooling properties? Which one works better for hot sleepers?

    1. Gel-infused mattresses use gel beads or particles to disperse heat and provide cooling. Latex mattresses, on the other hand, have a natural open-cell structure that allows for better air circulation and cooling. For hot sleepers, both can work well, but latex mattresses tend to excel in cooling due to their breathability and moisture-wicking properties. Gel-infused mattresses also offer cooling, but it might be a slightly different cooling sensation.

  3. I wanted to express my heartfelt thanks for your incredible article. It played a pivotal role in guiding my husband and me to select the perfect mattress for hot sleepers. We are thrilled to share that we chose the Emma Comfort mattress, and it has made a world of difference in our sleep quality.

    Your insights and recommendations were invaluable, and we couldn’t be happier with our choice. The comfort and cooling properties of the mattress have truly transformed our sleep experience. Thank you for your expert advice and for helping us make the right decision.

    1. I’m absolutely delighted to hear that the article helped you and your husband choose the Emma Comfort mattress. Your satisfaction and improved sleep quality are my top priorities, and it’s wonderful to know that the article played a part in that.

  4. Could you share your insights on how room temperature and the type of bedding can impact the cooling performance of a mattress for those of us who tend to sleep hot? I’m really interested in understanding this better as it could make a significant difference in my sleep quality.

    1. Room temperature and the type of bedding can have a notable impact on a mattress’s cooling effectiveness for hot sleepers. Maintaining a cooler room temperature and selecting breathable, moisture-wicking bedding can help enhance the cooling performance of your mattress. It’s a simple yet effective way to improve your sleep quality. If you have any more questions, feel free to ask!
