Our 8 Coolest Mattresses Reviewed
LUCID – Best in Support
In our opinion, the best cooling mattress is the LUCID.
This LUCID mattress should keep your body in a correct position while relieving pressure points. It does that thanks to its 2.5-inch memory foam layer. And, to ensure proper cooling, it is infused with cooling gel. At the same time, it is made of open cells, which increase the airflow and distribute the heat all along the surface.
Thanks to the cooling systems, its should stay comfortable no matter how hot it might get. And, to boost the airflow, the mattress is wrapped in a breathable cover.
Because this model has a medium feel, it should be appropriate for most people regardless of their sleeping position. If, however, you prefer something softer or firmer, it comes in those versions, as well. That way, you’re sure to find something you like.
Overall, this should be a well-balanced mattress for those that want great support. It is designed to prop your body up in all the right places, reduce the tension, and help you remain in a correct position regardless of how you sleep.
Brentwood Home – Best Non-toxic
Memory foam is made by exposing ordinary polyurethane foam to chemicals to give its properties, and those can remain in most mattresses when they arrive at your doorstep. That’s why it’s generally recommended to let them air out for several days before sleeping on them.
This Brentwood Home model is Greenguard Gold certified. That means its foam has been produced with a minimal amount of harmful chemicals, and its off-gassing should be at a negligible level. The certificate makes it safe for children and the elderly, as well as for use in hospitals, so you can be sure that the chemicals won’t cause any reactions.
At the same time, it will support your body and keep you propped up throughout the night. Its cover is made of bamboo and wool, so it is breathable and hypoallergenic. It also helps the mattress regulate its temperature better, and with that, help it remain refreshing.
So, if you’re looking for a mattress that won’t make your allergies worse, this one should cover those needs. Its off-gassing should be minimal, the cover breathable, and its foam aerated.
Nectar – Ideal for Any Sleep Position
You can determine what you need from your mattress from your sleeping position. If you rest on your back or stomach, you’ll usually find a firmer surface more comfortable. If you’re a side sleeper, on the other hand, you’ll need something softer to prevent shoulder or hip pain.
This Nectar model should cover most of these needs. It will shape itself to your contours if you rest on your side, letting you sink where you need to, which should reduce the tension in your shoulders and hips. At the same time, if you sleep on your back, your body should be kept in the correct position throughout the night.
To provide that support, it uses a combination of a gel-infused top layer with an open-cell memory foam comfort layer, all on top of a high-density foam base. That should make this product safe regardless of your sleeping position, while also keeping the surface refreshing.
All that makes this a balanced choice if you’re the type to change positions while you sleep. It is designed to prop your body up in all the right places, keeping it perfectly aligned, allowing you time to rest and rejuvenate.
Purple – Best Motion Isolation
If you’re sharing your bed with your partner, then you know how quickly their movement reaches you. If one of you has a rough night, the other feels it. Fortunately, some mattresses don’t carry the motion, and this Purple model provides just that.
Thanks to its proprietary foam, it keeps movements localized around their source, so you don’t have to worry about ruining your partner’s sleep with your tossing and turning. And, as it doesn’t use memory foam, it is also better at dispersing the heat.
To further help with that, its top polyfoam layer is aerated, which increases the airflow, preventing dust or moisture from lingering inside. At the same time, it should provide similar support, so you don’t have to worry about waking up stiff or sore.
While it doesn’t use memory foam, this model still provides plenty of comforts. Its construction helps keep you cool regardless of how hot the nights get, and thanks to the materials used, the movement should be isolated to its origin.
Live and Sleep – Best Eco-friendly
If you’re looking for an eco-friendly mattress, this Live and Sleep model could be what you need. Its packaging is recycled, and its foam is made with pressure rather than chemicals. That makes it an obvious choice if you care about the environmental impact of your chosen products.
It also carries the CertiPUR and OEKO-TEX certifications, which make this model safe. Off-gassing should be minimal and shouldn’t cause any reactions. At the same time, if you have problems with allergies, its cover is hypoallergenic, so you should be safe from dust, mites, mold, pollen, or other similar allergens while you sleep.
And its gel-cooled memory foam top should reinforce your body position correctly. The comfort layer under it is made of open-cell foam, which increases airflow and further helps with temperature regulation, keeping the surface refreshing, especially during those hot summer nights.
Those that want an eco-friendly mattress should seriously consider this model. Apart from being made without harmful chemicals, it also comes in a recycled package, all while providing all the comforts memory foam is known for.
Sweetnight – Best User-friendly
When you’re ordering a mattress online, things can be a bit tricky. You don’t get to try it before you buy it, and it comes directly to your house packed in a small box. This Sweetnight model should be a safe choice – after unpacking, you leave it for several days to decompress, after which it’s safe to sleep on.
To support your body while you rest, it uses a gel-cooled memory foam layer sandwiched between two high-density comfort layers. That should make the surface refreshing even if you live in a warmer climate.
And, to provide the fast response and bounce, it uses a base made of individually packed steel coils. That way, you get the advantages of innerspring options with added motion isolation. Its support is also zoned, so it should feel differently under your shoulders or hips, providing the optimal reinforcement to keep your body in a correct position.
This model should be simple to set up and use, so if you still have reservations about ordering a mattress online, this one shouldn’t give you any trouble. And, after several days, you’ll get a comfortable and reliable solution that should make your nights more restful.
PrimaSleep – Best Temperature Regulation
Temperature regulation can be essential for memory foam mattresses. Without it, they overheat easily, which could especially be problematic during hot summer nights. This PrimaSleep model has two systems to maintain its freshness – the top is infused with cooling gel, and beneath it lies a layer of convoluted airflow foam.
That way, the gel should disperse some of your heat along the surface, while the increased airflow should take some of it outside the mattress. To further boost the cooling, its cover is breathable and it won’t trap air, dust, or moisture inside, keeping it safe from dust mites, mold, or bacteria.
At the same time, it aims to keep your posture healthy, helping your body to rest and rejuvenate. You should be aware, however, that it is a plush feeling mattress, and if you prefer something firmer, you could buy a topper.
So, if you’d like to buy a memory foam mattress for its superior support, but are worried about its heat retention, this model should have that covered. The combination of a cooling gel infusion with an airflow layer of convoluted foam should keep the top refreshing regardless of how hot the night gets.
Molblly – Best Hypoallergenic
If you suffer from allergies, you probably want a mattress that can help ease the symptoms by reducing allergens in your bedroom. This Molblly model should do just that. Memory foam is, in itself, resistant to dust mites and bacteria, and the hypoallergenic cover should keep other particles such as pollen or mold away.
It is also CertiPUR and OEKO-TEX certified, so the number of harmful emissions should be negligible, if at all present. That way, you know that the chemicals it was made with won’t cause an allergic reaction while you sleep.
To keep the surface fresh, it uses an infusion of cooling gel directly into the memory foam top, which should help you remain comfortable if you sleep hot. At the same time, its high-density base and the foam comfort layer should improve the response and comfort, keeping your body in a correct position while you sleep.
That’s why this mattress could be ideal for those suffering from allergies. It should keep common allergens away while correctly supporting your body, giving it a chance to rest and heal, all while keeping the surface as refreshing as possible.
Cooling Mattress: A Comprehensive Overview
You may be wondering, what are cooling mattresses? How are they made, and how are they different from traditional ones? And why might you need one?
This section should answer these questions and provide you with vital information about them. That way, after reading this, you should know all you need to make an informed decision.
What's a Cooling Mattress?
A cooling mattress is usually a product whose surface is cooled in one way or another. Most frequently, it is done in one of two ways – by increasing the airflow or with an infusion of a cooling agent, usually gel. Some models combine these two methods, as they aren’t mutually exclusive.
Some materials need more cooling than others. If, for example, you’re looking for something with memory foam, and you’re a hot sleeper, you should generally find something with at least one cooling system. Other materials such as latex or coil don’t have as big of a problem with heat retention.
These beds are usually meant either for those that have a problem that causes them to sleep hot (more on that later), or those that live in a warmer climate and might need more active cooling in the night.
What's the Best Material for Cooling a Mattress?
As we’ve said, some materials need more cooling than others, and this section should help you understand their differences, as well as their advantages.
Gel Infused Foam
This is the most frequent type you’ll encounter. While memory foam has good supportive qualities and is usually pretty comfortable, its main disadvantage is its heat retention. That’s caused by its main property – as it gets warmer, it gets softer. That’s what helps it mold to your body and distribute your weight along the surface.
At the same time, that same property causes it to retain that heat around you. Because of that, most modern options that use this material also use an infusion of cooling gel to help distribute the heat throughout the mattresses.
The gel absorbs the heat and passes it around, simultaneously cooling you and heating the surrounding area. Usually, that should be enough to cool you down and improve your sleep, but in some cases, that might not be enough. In those cases, the gel-infused top is paired with an airflow layer to further help cool the surface.
Check our guide for top gel infused memory foam beds on the market.
Great latex options are generally more expensive, especially if it’s natural. It is made from the sap of the rubber tree, and it is much bouncier and more responsive than memory foam. It also doesn’t retain heat, so it should be a safe choice for those that sleep hot.
As it can be expensive, usually only the top layer is made of it, forming a hybrid (check top latex hybrid beds here) with either a foam or innerspring base. Those are generally cheaper while also retaining the properties latex is known for.
The top layer is usually aerated, which means it has holes to boost the airflow. That should keep it fresh. It can also be paired with an airflow layer to further increase its cooling effect.
While ordinary memory foam beds can get warm during the night, when paired with an airflow layer, it should remain fresh enough. However, most modern models use an open-cell version of it, and that has better airflow when compared to the older models.
Pairing an open-cell memory foam top with an airflow layer should provide a refreshing sleeping surface. Gel-cooled memory foam is usually the better option, though, as it is better at remaining fresh. So, if you have problems with hot sleeping, you might want to choose something like that.
If you also live in a warmer climate, the surface could quickly warm up enough for it to lose its firmness. If that happens, your body won’t be correctly supported throughout the night. You could regularly find yourself tossing and turning, sweating through the night.
A cover made of bamboo can also help cool the surface. It is a breathable material, and it should help the air move the warmth out. It should also carry the moisture away from you, absorbing it along the way. And, as it cools quickly, it should also help keep the mattress free of bacteria or mold.
As it is breathable, it should also be better at transporting the coldness from the gel, helping the top cool you. At the same time, it is also hypoallergenic, and it should help keep your sleeping surface healthy and refreshing.
It can, however, be more expensive. But if you can find a model that uses a cover made of bamboo, you should feel the difference, especially when compared to other traditional materials such as polyester.
If you need more sustainable option check our picks for best bamboo mattresses.
Coils are the traditional method with which the mattresses were made. It uses a series of steel coils lined up inside, and they help prop your body up, shaping the surface to it, helping it distribute your weight better.
That also means it has plenty of space in the middle, which can, under the pressure of your body weight, push the air out. That should form a natural airflow, which can help keep the surface fresh.
They have their disadvantages, though. They aren’t as resistant to dust mites, mold, or bacteria, and they may need extra maintenance to prevent an infestation. The cheaper models can also start to sag sooner.
If you need extra cooling, you could find a hybrid that uses individually wrapped coils as a base for a gel-cooled top layer. That way, you get the bounce and responsiveness of innerspring options together with the refreshing surface the cooling gel provides.
Unlike memory foam, polyfoam doesn’t retain heat, and that’s its chief advantage. Its disadvantages, though, are numerous. It isn’t as durable and can start to sag much sooner. Its durability mostly depends on its density, and if you want something that will last longer, you’ll need something denser. Unfortunately, that also means something heavier and firmer.
Some manufacturers like Purple or Tuft and Needle use a proprietary form of polyfoam to provide a refreshing surface. Those are, however, usually full holes for airflow, which also helps reduce the firmness and weight.
Apart from those, you’ll usually find this material in cheaper mattresses or pads. Their lack of durability and excessive firmness can be an advantage there.
In most cases, however, this material will form the base for memory foam or latex, mostly in its high-density form. There, their firmness won’t be a problem, as the top layers should provide enough comfort.
What's the Best Cover to Use?
Cover can also be a vital aspect if you’re looking for a cooling solution. An unsuitable cover could trap the heat on the surface, preventing it from dispersing through the mattress. It can also prevent it from cooling you.
This section will give you an overview of how different materials affect the cooling abilities.
Traditional mattresses have used quilted covers, and this is still a prevalent method. What it means can vary, though. Some are more breathable than others, and in some modern solutions, an additional foam layer can be quilted into the cover, improving its comfort.
While they usually retain heat a bit more than the alternatives, they can still provide limited cooling abilities. Some manufacturers also quilt cooling gel directly into the cover to help with that.
Overall, the material might not be the most breathable option. If you’ve got problems with heat, they might not be the right answer, especially if they don’t include any additional cooling layers. However, if they’re thin and breathable enough, they might not hinder the cooling abilities too much.
Non-quilted covers are a bit cheaper and should be a better option than their quilted counterparts. They are thinner and more breathable, but you should also pay attention to the material it’s made of. Some aren’t as good at dispersing heat and could cause you to heat up while you sleep.
That’s why these are the most common cover types, especially among online products. In fact, most of the products in our selection use such a material, as it can be the best affordable option for breathability and cooling. You should keep in mind, though, that the non-quilted variety isn’t as durable as other options, especially when it’s a thin layer.
Fabrics that Assist in Cooling
As we’ve mentioned, some materials are better at cooling than others. Some isolate the warmth on the surface, trapping you in your body heat, while others help disperse it throughout the mattress, whether by increased breathability, or a better ability to transfer heat.
Some natural materials such as wool, bamboo, or cotton (it’ll work perfectly with top rated cotton mattresses from our guide) are good at being breathable, and they transfer the heat well, so those should be the ideal choice for the cover. They can be expensive, though, and if you’re looking for cheaper alternatives, some synthetic materials can also do the job.
Polyester, for example, can isolate the heat, keeping it on the surface. In its performance variety, however, the kind used in sportswear, it can transfer heat almost as good as natural materials. It also wicks moisture away from you, and as it dries quickly, it shouldn’t cause any problems.
Lycra, also known as spandex, is another synthetic material regularly used in sports clothing, usually combined with polyester. It has similar properties, and it could help keep the surface fresh.
Another material that can help with your temperature regulation is celliant. It is less common in mattress covers, but some manufacturers do use it. It essentially turns your body heat into infrared light, which helps your temperature regulation by boosting the circulation and oxygenation.
While other materials cool you down by transferring the heat away from you, phase-change substances are attuned to a particular temperature. They will absorb the heat until you cool down to that temperature, and if you surpass it, they will release it to warm you up.
That way, they maintain a consistent temperature throughout the night and can be great for both those that sleep hot or cold. They aren’t universal, though, and if you share a bed, it can cause problems for your partner. They may not be as attuned to a specific temperature as you, or they may have different preferences.
Cold Wire Technology
This usually means that there is a specific fiber woven into the cover, which then works similarly to phase-change materials – it absorbs the excess heat, which it releases if you cool down too much. They also whisk away any excess moisture away from you, which could also lengthen the lifespan of the mattress.
Accessories and Systems that Helps in Cooling the Mattress
In addition to a cooling mattress, several accessories could help you regulate your heat, and this section will give you some essential information about them.
This primarily refers to toppers that rely on cooling materials to regulate the temperature. They usually don’t require electricity, and instead, rely on transferring the heat away from you. They should also increase the airflow, helping your mattress breathe more.
They can be a lifesaver if you only want something that can cool you down during the hot summer nights. If you use a topper, you can simply remove it when you no longer need it. That way, your sleeping surface won’t cool you down in the winter, when you don’t want it to.
Some are based on cooling gel, others on copper infusion, cold wire technology, or phase-changing materials. They should all help reduce the temperature and distribute the heat throughout the surface and the mattress beneath.
These could be an ideal choice if you don’t want to replace your mattress, but don’t want anything that requires electricity, either. They should keep you cool enough to boost the quality of your sleep, but they don’t have any additional costs.
Quality sheets can also help you maintain a natural temperature, and bamboo is especially valued for these properties. While bamboo sheets don’t transfer heat away from you, their breathability does have a cooling effect. They could help you remain fresh during summer nights. At the same time, the sheets are soft to the touch, making them extremely comfortable.
They also wick the moisture away from you, and they dry quickly. That should, in turn, reduce the chances for mold and bacteria to develop in your mattress, making them hypoallergenic. That’s what makes them an ideal choice for your children, as well, as they’re usually more sensitive to allergens than adults.
While they do cost more, they are much more durable, and they don’t absorb oils from your skin. That way, they’ll never change their colors as traditional sheets do, and they’ll look as fresh and new as the day you bought them.
Electric Cooling Pads
This is usually a type of topper that needs electrical power to work. They are made to maintain a constant temperature, which could help you cool down when you sleep. As they use electricity, though, they could get expensive in time.
They are usually thinner than cooling toppers, and they can be a better solution if those can’t cool you down enough. For example, if you sleep hot during a heatwave, there is no amount of cooling gel that can help you maintain a healthy temperature and prevent overheating. In those cases, electric cooling pads could be a lifesaver.
Some more expensive models can also work both ways – they can cool you or warm you up. That way, you have two products in one, one that can keep you refreshed during the hot summer nights, and one that can warm you up during the winter.
The BedJet Cooling System
If none of the other options work and you want to spare no expense to keep your mattress fresh, then BedJet Cooling System might be for you. It is a complete climate-control solution for your bed. It will cool the surface down or warm it up, and it is controlled by your smartphone.
It consists of a unit that you place beside your bed and a hose that blows the fresh air directly under your sheets. That should help maintain their freshness regardless of how hot the nights get, and you’re in complete control over how hot or cold your sleeping experience is.
They have a filter to prevent it from blowing dust on your sheets, and they’re surprisingly silent, much quieter than traditional air-conditioning.
Some cheaper models don’t have any air-conditioning; instead, they simply blow the air onto your sheets, helping maintain a healthy airflow, but if you want more cooling, you might need to pay for it.
A cooling system isn’t reserved only for mattresses and toppers. If you feel like your pillow gets too warm to be comfortable, or you find yourself flipping it to its fresh side just to relax a little better, you might want to consider buying a cooling pillow.
They come in a wide variety of shapes and sizes. Some have a dent in the middle to better support your neck, while others allow you to adjust its support levels to help you find the ideal shape.
Usually, they cool you down either with a cooling gel or water. The gel is more common among memory foam pillows, as those can get warm quickly. They should provide a refreshing surface for your head, and in no time, you’ll find that you’ve stopped flipping the pillow to its cool side.
Cooling pillows that use water usually have a pouch you need to fill. They can be comfortable as they are better at adapting to you. Most are customizable, as well. They can be weighty, though, and noisy if you accidentally let air into the pouch.
Innovation from Mattress Brands
After reading about all these innovations, you must be thinking that they’re reserved for more expensive mattresses. Fortunately, that is not the case.
Budget brands that sell online usually do it at a lower price. That allows them to offer you more options for a more approachable price. For the same amount of money that you’d spend on a quality cooling mattress in a store, you could find a much better solution online.
And while all these innovations usually start at the most expensive end, thanks to these budget brands, they can be approachable even for ordinary people. They can include these systems for a bit of a price increase, but that should still be cheaper than those you’d buy in a store.
That can be the most prominent advantage of buying online. And while you won’t get to try them out, you can still get advice using the chat systems most manufacturers have in place.
Shop Online or In a Store?
As we’ve mentioned, the main advantage of buying online is that you get more for your money. The mattress you saw and found to be comfortable in the store? You’ll probably find a better deal online, ready to be delivered to your door. And if you’re willing to spend that much in a store, for the same money, you can likely find a better product online.
So, what are the disadvantages? Why would anyone buy something in a store when buying online seems to have so many clear benefits?
The most obvious one is, when you’re buying in a store, you can walk around and try different models as many times as you’d like before making a final decision. You also have salespeople around, and they can answer most of your questions and help you narrow your search down.
While most manufacturers who sell online offer sleep trials, if you take advantage of these offers, it could be weeks, if not months before you finally settle on a product you find comfortable.
In the end, the answer depends on you. If, however, you want to save some money or get a good deal for a better model, online seems like the obvious answer.
Why Do People Sleep Hot?
Now that you know more about cooling mattresses, you may be wondering, do you even need one? Who could have such problems? Who could overheat so much in the night that they might need additional cooling? This section should answer these questions and help you understand if you need such a product.
Anxiety & Night Sweats
Anxiety can increase the blood flow throughout your body, which can cause you to overheat. The normal physiological response to that is an increase in sweating. Unfortunately, these can happen even during the night, and they’re usually called night sweats.
While a cooler sleeping surface won’t help with the cause, it can ease the symptoms by making your nights more relaxing. And, after a solid rest, your anxiety might let up a little, too.
Alcohol & Night Sweats
Another common cause of night sweats is alcohol. Some people might enjoy a nightcap, feeling it might help them relax better. The drink, however, will increase your blood flow, and with that, your body temperature. That could, in turn, lead to a sweatier night’s sleep.
Alcohol can also dehydrate pretty quickly while you sleep, so it might not be the best choice of drink before bedtime. If you enjoy a nightcap and have problems with night sweats, you might want to replace that drink with water and see if that helps.
Hot flashes are a common sign of menopause. They are usually a warm sensation, and it can affect anything. You can feel it in your fingers or toes, for example, or it could hit your arms. It could also have an effect on your chest and cause you to sweat more. They can last anywhere from a few moments to several minutes.
If they happen during the night, they could lead to an increase in sweating, which could reduce the quality of your sleep. A reliable cooling system can dramatically help you in that regard, and that can help you feel more rested during the day, as well.
Additionally, if that happens during the night, you might try lowering your air conditioning, as well, as that might offer you some help until they pass. A cooling topper is another option, and you could also get a cooling blanket, as well.
Change in Temperature
Your body temperature changes throughout the day, and that is a normal process. It happens without you even knowing it. It also fluctuates during the night, which can cause you to feel cold in one moment, and then hot during the next.
That’s why breathability is crucial for the proper regulation of your body temperature. It will help you maintain your warmth on an appropriate level as it shifts throughout the night, and that’s why most of our recommendations use such materials.
You might also need a material that can absorb the heat, only to release it back to you when you cool down under that threshold. The cooling gel should do that. That should prevent you from freezing, as well.
Also, while conventional wisdom dictates that you need to stay warm throughout the night, that might not be completely accurate. People who prefer to sleep in a colder bedroom usually sleep tighter and wake up feeling more rested.
Frequently Asked Questions
Are Side Sleepers Usually Hot Sleepers?
Generally, no. The side sleeper position doesn’t usually have an effect on overheating. However, when you sleep on your side, you are not in contact with your mattress as much, which also means that, if it has a cooling system, it might not be as effective.
You should also note that during hot summer nights, sleeping on your back can cause you to breathe through your mouth, which can cause overheating. Sleeping on your side might prevent that and help your body regulate your temperature better.
Are Electric Cooling Pads Safe?
While they’re generally safe, as they use electricity, you’ll need to take some necessary precautions. That means, you need to keep an eye out for the cables, and their wear and tear, and you need to avoid touching them with wet hands.
Also, if you have pets, you’d probably not want them chewing through the pads, as that could cause all sorts of damage.
Are These Safe for Back Pain Sufferers?
It depends. Heating pads are usually recommended for back pain, as they help relax the muscles and relieve the symptoms that way. If, however, you’re into sports, you might find that a cooling pad could ease aches, especially after training. They help with the circulation, which also reduces inflammation.
Just to be sure, however, you should consult your doctor before buying either a heating or cooling pad.
Cooling mattresses come in a wide variety of constructions, shapes, and sizes. Some use a cooling agent to transfer the heat away from you, others are made specifically to increase the airflow, which helps keep the surface refreshing.
