1. How Does A Cooling Mattress Work?

A cooling mattress is designed to help people who have difficulty sleeping due to excess heat, which gets trapped in the mattress. This happens because humans, being warm-blooded, tend to increase the temperature of the surfaces they come in contact with, such as blankets and mattresses. 

Higher prevailing temperatures prevent the body's temperature from falling by a couple of degrees, which is essential for comfortable sleep. In such situations, cooling mattresses can come in handy by dispersing off any residual heat generated by your body, helping regulate the temperature effectively.  

Most cooling mattresses on the market work by drawing away hot air from your body while absorbing the heat present in the room. Such mattresses are generally designed using a wide range of materials and technologies that can help solve this problem. These technologies may include wrapped wire coils, cooling gel-infused foam, or even natural materials like bamboo and charcoal.  

The various materials used in cooling mattresses perform specific functions that make such mattresses effective. For instance, the core of such mattresses can be made from materials like latex, innerspring, or other materials which improve the airflow for better cooling. 

However, the most important role in the process is that of the topmost layer, which can absorb, retain, or disperse heat depending on the material used for its construction. This layer generally consists of gels, phase change molecules, or natural fibres like latex foam for temperature regulation. 

2. What Are Some Benefits Of Cooling Mattresses?

There are several benefits of cooling mattresses, such as:

1. Promoting Better Sleep

Higher temperatures can prevent you from falling asleep, disrupting your sleep cycle. With the help of cooling mattresses, heat can be dispersed effectively, preventing the body from overheating. This allows you to fall asleep more quickly and prevents disturbances throughout the night, ensuring a deeper, more comfortable night’s sleep. 

2. Helping Save Energy

During summers, hot sleepers can experience even more discomfort, often relying on air conditioners for longer periods. This, in turn, leads to higher electricity bills. However, using cooling mattresses can help keep the temperature under control to some extent, reducing reliance on the air conditioner. 

3. Providing Relief From Night Sweats 

Night sweats can occur due to several reasons apart from the heat, such as sleep disorders, anxiety, or reactions to certain medications. Identifying the cause of the problem is not generally easy, but some relief can be obtained by using a cooling mattress. 

Such mattresses often have certain features like moisture-wicking technologies, which can soak away sweat, helping you sleep comfortably. 

4. Ideal For Multiple Sleepers Sharing A Bed

If you share your bed with a partner, the problem of excess heat can become even worse, especially during the summer. With a regular mattress, the situation can become quite unbearable. However, this problem can be resolved using a cooling mattress as heat is eliminated through various cooling technologies.

5. May Be Better For The Environment 

While not all cooling mattresses are good for the planet, a few options use materials like Tencel, which are completely natural. Similarly, some mattresses utilise charcoal or graphite for heat absorption, which are better alternatives to synthetic chemicals. 

3. What Are Some Of The Cooling Materials Used By Cooling Mattresses?

Cooling mattresses from various brands utilise different types of materials, and some of the most popular ones include:

1. Gel Infused Foam

The most popular material used in cooling mattresses is cooling gel, most commonly found in foam gel mattresses. These mattresses contain gel microbeads in several layers that work by absorbing heat from the body to keep you cool while sleeping. 

Cooling gel memory foam is used in hybrid mattresses and memory foam ones and can even be used in mattress toppers. 

2. Advanced Memory Foam

Unlike standard memory foam made from polyurethane which traps heat, advanced memory foam does not retain much heat and is more breathable. It usually contains several tiny holes that allow gel-infused beads or air to pass freely, allowing better cooling.  

3. Regular Springs And Coils

The standard springs and coils used in mattresses are constructed using steel and are used in the core layer of the mattress. These coils or springs have plenty of space in between to allow the air to flow easily, helping keep the mattress cool. 

4. Pocket Coils

Unlike traditional spring mattresses, cooling mattresses using pocket coils are different. This is because every spring is covered in a separate fabric section. These springs are packed more tightly together than in standard spring mattresses, which allows the mattresses to adjust easily to your body. This also promotes better airflow than regular memory foam mattress options. 

Pocket coils are most effective in hybrid mattresses since the coils work together with gel and memory foams offering the best combination of cooling, support, and moisture wicking.

5. Latex

Natural latex is produced from the sap of rubber trees and is generally cooler than foam but may trap heat. There are two types of latex used for mattress construction, Talalay and Dunlop, with the former trapping a lower amount of heat. 

Also, synthetic latex traps more heat than natural latex, though just like natural latex, it can be aerated to improve breathability. 

6. Phase Change Materials

Phase Change Materials or PCMs are specialised materials which can release and absorb heat energy through freezing and melting. While water is the original PCM, modern mattresses utilise other materials for more efficient heat absorption. 

This allows them to absorb heat faster and for longer periods, making them ideal for cooling mattresses. PCMs in such mattresses can absorb excess heat energy from your body during sleep, helping prevent discomfort. 

7. Open Cell Foam

Open cell foam was originally developed as an alternative to pocket coil mattresses and has numerous holes arranged in patterns. These holes promote better airflow, so that radiant heat is dispersed more effectively. 

Most brands producing memory foam utilise this material for their cooling mattresses, though each uses a different pattern. 

4. What Are Some Of The Things To Consider When Buying A Cooling Mattress?

There are several factors to consider besides the cooling features when looking for a cooling mattress. This is especially important if you don’t want to end up with a mattress that is effective in cooling but does not offer proper support or cannot justify its price. So, here are some factors to keep in mind:

1. Mattress Type

The type of mattress you require should be the first factor to be considered, as there are many options to choose from, including memory foam, hybrid, innerspring, etc. Regarding cooling capabilities, hybrid and innerspring mattresses tend to trap less body heat than memory foam ones, making them better options.

This is because air can flow freely through their coils, whereas foam ones lack spaces that promote airflow. 

2. Quality Of Materials

Every material used to construct a mattress is available in several quality levels. For instance, foam made from denser polyfoam tends to be of much better quality than that made from less dense material. Better quality foam tends to be more durable and resilient and can retain its shape more effectively for a longer period. 

Similarly, mattresses made from natural latex are of higher quality and offer greater support than those made from synthetic latex. 

3. Pressure Relief

A mattress that can distribute your weight properly over its surface can relieve pressure on various body parts more effectively. On the other hand, mattresses that do not offer proper weight distribution result in greater pressure when you sleep, which can lead to pain and discomfort. 

Keep in mind that extremely soft or too firm mattresses can both lead to the development of pressure points. 

4. Contouring

Contouring or conforming is the ability of a mattress to adjust to the shape of your body and can affect how much heat gets trapped. A mattress that can conform to the body effectively, such as a memory foam one, will trap a higher amount of heat. That is the reason why many cooling mattresses do not contour very well. 

Innerspring mattresses, for example, retain their natural shape and do not adapt to your body, which is why they do not trap as much heat.  

5. Sleeping Position

Your sleeping position determines the type of mattress you should choose and how firm it should be. For instance, side sleepers generally prefer mattresses on the softer side though these mattresses can trap more heat. On the other hand, back sleepers like options that offer a firmer feel which has the additional advantage of temperature regulation. 

But remember that your body weight will determine how firm or soft a mattress feels. 

6. Level Of Firmness

The firmness of a mattress can be measured on a scale that starts from one and goes up to ten, with one being the softest and ten being the firmest. How soft or firm a mattress is can directly affect its cooling ability, as firmer mattresses are not very contouring and thus remain cooler than softer ones. 

The average firmness range for most people lies between 4.5 and 6.5, though people with more weight prefer heavier options. However, firmness is a subjective matter, so it’s best to take advantage of trial periods and try multiple mattresses for some time before settling on one. 

7. Edge Support

Edge support refers to how firm the edges of a mattress are and can determine the support provided when you sit or lie on the edge. Mattresses offering better edge support prevent you from falling off when sleeping on the edge while making it easier to get in and out of bed. 

8. Temperature Regulation

Efficient temperature regulation is important to prevent overheating at night, and various materials work differently for this purpose. For instance, coil layers allow the free flow of air, which helps regulate the temperature effectively, while foam layers can absorb body heat to keep you cool. 

9. Noise Reduction

Some mattresses tend to make noise when you get into bed or move around on them, disturbing your partner. The noise produced depends upon the material used in the construction of the mattress, and generally, foam mattresses are the most silent. 

Innerspring and hybrid mattresses produce more sound because of the presence of the coils, though pocket coils are not as noisy. 

10. Price 

Cooling mattresses are available at several different price points, and you can find both cheap and highly expensive options on the market. The price of a mattress depends upon the materials used in its construction, and mattresses using better quality materials that last longer tend to cost more. 

That said, it is possible to find some good-quality yet affordable options on the market. Another thing to consider is that mattresses sold online are generally more affordable since the manufacturer does not have to spend on showrooms and staff. 

5. Are Cooling Mattresses Effective?

Mattresses designed to promote better cooling use materials that can improve the airflow and disperse heat more effectively. That said, not all cooling mattresses work equally well, and some options are better at regulating the temperature. 

Overall, hybrid mattresses are the most effective as far as cooling capabilities are concerned, as they often contain aerated latex, which allows better air circulation. The coils at the bottom also promote better airflow, and the mattress covers of hybrid options are made from natural materials, such as organic wool or cotton, for better cooling. 

Latex mattresses are also effective in controlling the temperature and preventing overheating, while foam ones tend to trap heat. That is why they often contain materials like graphite or cooling gel which can absorb heat. 


While there are many options on the market for people looking for cooling mattresses, finding the right one will require some time and effort. The most effective way is to test out mattresses that you think might be suitable, and most manufacturers offer a reasonable trial period for this purpose. 

Or, you could just go with the Nectar Memory Foam Mattress, which has a quilted cooling cover and dynamic layers that deliver the perfect sleeping experience. It also comes with an excellent warranty and trial period, so you can try it out first.

On that note, it’s time to conclude this guide. Until next time!
