If you have a tendency to sleep hot, the mattress's bamboo charcoal cover and Sensapole technology will prevent your body from overheating for a peaceful and sweat-free slumber. 


1. Why do soft mattresses make you sweat? 

It's not always a malfunctioning air-cooler or fan making you lose sleep because of excessive sweating and overheating. Your mattress can be the real culprit behind hot and sleepless nights, especially if you're a hot sleeper. 

A soft and sagging mattress can reduce your body's air exposure to trap heat, which is particularly true for any traditional memory foam mattress. The body-contouring quality of the memory foam layer often leads to a sinking feeling while reducing body-to-air contact. Even though the cradling feeling might seem soft and comforting, it can prevent heat dissipation to naturally heat up your body, making you feel sweaty or suffocated. 

Similarly, an old and saggy mattress can lead to more heat retention, so you might wake up feeling sweaty in the middle of the night. The foam layers or spring coils of old mattresses lose their firmness over time, making them less bouncy and saggier. That's why they tend to sink excessively under pressure and trap more body heat without any heat dissipation. 

New and firm mattresses might offer less body contouring and promote breathability to prevent overheating. Moreover, hybrid pocket spring mattresses might be a better alternative to softer mattresses because of their medium-firm feel for better air exposure to let your body breathe. So, if you tend to sleep hot, it's best to avoid soft foam mattresses that sink too much. 

2. What are the factors to consider while buying a cooling mattress?

A. Mattress Type 

Some mattresses are better at heat dissipation than others. There are different mattress types, such as all-foam, hybrid, innerspring, and latex mattresses, with varied cooling abilities. 

In this context, innerspring and hybrid mattresses are known to be much more temperature neutral than polyfoam or memory foam mattresses because of their superior breathability and airflow. Note that the heat retention of any hybrid mattress is far less than even the best memory foam mattress. 

Memory foams usually trap body heat and can lead to excessive sweating or discomfort. However, gel memory foam is an exception because it contains cooling gel particles to regulate your body temperature while sleeping. 

B. Temperature Regulation 

Specialty cooling mattresses are designed to regulate temperature and promote airflow even if you're not prone to sleeping hot at night. The entire mattress construction contributes to creating an ambient temperature during every season without getting too hot or too cold. 

These mattresses often feature special cover fabrics, like bamboo charcoal, along with gel-infused foam comfort layers to absorb body heat for a cool and sweat-free slumber. Additionally, the individually wrapped spring coils of hybrid and innerspring mattresses facilitate better air circulation to dissipate body heat and cool your body temperature. 

C. Contouring

Contouring essentially signifies how much the mattress is hugging your body while you lay on the surface. A softer mattress offers more body contouring compared to a firm mattress but traps more heat. That's why as a plush mattress, memory foams are responsible for excessive sweating in hot sleepers.

Cooling mattresses usually don't feature high body-contouring materials like memory foams or polyfoams. Thus, innerspring and hybrid mattresses work much better as cooling mattresses due to their bouncy spring coils, offering enhanced back support and temperature regulation. 

D. Quality Materials

The material quality of a mattress always plays an important role in reducing heat retention and improving breathability. For instance, a high-quality, high-density foam mattress will be much more durable and resistant to sagging while facilitating better airflow. 

Natural latex mattresses also offer much more responsiveness and better temperature regulation than any synthetic latex mattress material. Thus, if you want to determine the cooling efficiency of a quality mattress, closely study its materials.

E. Mattress Firmness 

The mattress firmness is measured on a scale ranging from 1-10, where 1 is the softest and 10 is the firmest. Depending on firmness, you can determine whether a mattress will sink too much. In fact, firm mattresses usually offer less body contouring and prevent overheating of your body. 

Hot sleepers usually prefer medium-firm mattresses to avoid excessive sinkage and reduce body heat. Firm mattresses also help in air exposure by improving the body-to-air contact ratio, which keeps your body much more cool while sleeping than any soft mattress. Typically, people prefer using mattresses around the 6.5 firmness range, but heavier sleepers often go for firmer mattresses. 

F. Pressure Relief 

Pressure relief is an important feature to consider while purchasing any mattress because if the mattress is too soft or too firm, it creates pressure points. This results in discomfort or pain down the road. 

Always choose a mattress that evenly distributes your body weight to offer superior pressure relief, along with regulating your body temperature. In that way, you won't suffer from back or joint pains while sleeping on your new mattress. 

G. Edge Support

A mattress with enhanced edge support allows you to spread across the entire mattress surface without the risk of rolling off the edge. When there’s more space on the mattress surface, you can easily sprawl out which increases the body's air exposure. 

With superior edge support, you won't feel stuck inside the mattress and it will allow your body to breathe for better heat dissipation throughout the night. 

H. Affordability 

The prices of cooling mattresses vary based on the quality of the materials and their construction. Hybrid cooling mattresses usually cost more than traditional memory foam mattresses because of their advanced cooling technologies. 

That said, you can find cheaper, high-quality cooling mattresses if you purchase them online. 

3. What are the cooling properties of different types of mattresses?

A. Hybrid Mattress

Hybrid models come with a coil support core to facilitate airflow through the mattress layers, which prevents the body from trapping excess heat and keeps hot sleepers cool. Thus, most hybrid mattress models are temperature neutral. 

If a hybrid mattress has latex comfort layers, it can enhance cooling, while memory foam can trap more heat. So, make sure to check the material of a hybrid model before purchasing it. 

B. Foam Mattress

Since any traditional foam mattress is known to trap heat because of its conforming quality, manufacturers usually add cooling materials to prevent heat retention. For instance, gel-infused memory foam is better at absorbing body heat and bringing down your core body temperature. Charcoal, graphite, or diamond are also infused with foam comfort layers to offer enhanced cooling. 

C. Innerspring Mattress

Innerspring mattresses are naturally cooling because of their thick coil layers that promote air circulation. Even if these mattresses have a memory foam layer, it's quite thin and cannot trap much body heat, so their cooling ability isn't affected. Plus, innerspring models are much more affordable than all-foam or hybrid variants. 

D. Latex Mattress

Natural latex comes with superb cooling ability because of its high porosity that facilitates airflow to dissipate the body heat of hot sleepers. Many manufacturers often aerate or perforate the layers of latex mattresses to increase airflow for improved temperature regulation. 

4. What are the common cooling mattress materials?

A. Coils And Springs 

Coils or springs are usually made of steel and used to construct the support core in innerspring and hybrid models. Since there's sufficient space between each coil, they promote better airflow throughout the mattress and coolthe top comfort layers. 

B. Latex

Natural and organic latex is made of tree sap, and it's usually much cooler than foam. It can be easily aerated to offer better breathability but synthetic latex has a tendency to trap more heat than natural or organic latex. 

C. Gel-Infused Foam

Some mattress brands incorporate small cooling gel capsules inside the foam layers to bring down the body temperature of hot sleepers. However, there's some debate about the efficiency of such gel-infused foam in heat dissipation. 

D. Basic Memory Foam 

Basic or traditional memory foam is made of polyurethane and offers a cradling feeling because of its body-contouring quality, which can trap heat. Since basic memory foam retains heat, hot sleepers might find it uncomfortable while sleeping on these mattresses. 

E. Advanced Memory Foam 

Advanced memory foam is an upgraded version of basic memory foam that allows better breathability and less heat retention. It often contains numerous ventilation holes to increase air circulation and prevent overheating. 

F. Basic Polyfoam

Similar to memory foam, basic polyfoam is also made of polyurethane and can trap heat. It's often used as a comfort layer or as a support core and is much less body-conforming than memory foam. 

G. Advanced Polyfoam 

Advanced polyfoam comes with small air pockets or channels of air cells to promote airflow and breathability. So, it's much more temperature neutral than basic polyfoam. 

5. How can you keep your mattress cool?

A. Sheets 

Lightweight cotton or linen sheets made of natural fibres can improve the breathability of your mattress to reduce heat retention. Avoid using heavyweight cotton or flannel sheets because they are designed to retain heat and promote insulation. You can also go for sheets made of natural Tencel lyocell fibres because of their moisture-wicking quality. 

B. Pillows 

There are several cooling pillows that can help you bring down the temperature of your mattress. For instance, latex or memory foam cooling pillows infused with cooling materials or gel can be excellent in creating a cool and ambient sleeping environment. Cooling pillows with water or air chambers can also help in bringing down body heat at night. 

C. Blankets 

Hot sleepers should avoid using wool, cashmere, or fleece blankets because these are some of the warmest blankets. It's best to use lighter and thinner blankets to keep your mattresses cool, like linen, light cotton, Tencel lyocell, or cotton blend blankets.
