The most popular cooling mattress materials

Last Updated on March 22, 2022

The human body temperature naturally increases and decreases over the course of 24 hours. Some studies suggest that your temperature changes during different sleep cycle stages, reaching its lowest levels as NREM (non-rapid eye movement) sleep begins. 

This decrease in body temperature promotes better sleep, whereas higher temperatures might disrupt your sleep cycle. As a result, sleep experts designed cooling mattresses that are crafted with breathable components to help you sleep better and longer with interruptions.

Some individuals naturally run hotter than others, especially at night while in bed. A cooling mattress can make the difference between a good night’s rest and a night full of sweaty tossing and turning for these sleepers.

The construction of your bed and the materials used in comfort layers, support cores, and cover fabrics is what plays a significant role in how well or how poorly a mattress will regulate temperature.

That’s why in today’s article, we’ll discuss the most popular cooling mattress materials and which one will work best for your specific needs.

What are the most popular cooling mattress materials?

As we mentioned above, cooling mattresses can be constructed with various materials, some with better cooling properties than others. However, the material you choose is a personal preference, but keep in mind that each type comes with its own pros and cons.

Usually, people who sleep hot need to look for components that offer cooling or are breathable due to gel infusions or coil layers. Here are the most common versions:


This natural material is made from a rubber tree called sap, which is generally cooler. However, synthetic latex tends to trap heat more than natural ones. Remember that all types of latex should be aerated for breathability before use for at least 48 hours.

Coils and springs

Coils and pocket springs are often made from steel (gauge). They offer great support and excellent airflow throughout the entire mattress, which cools the comfort layers above. However, for many, the noise can be an issue that disrupts their rest.

Traditional memory foam

Traditional memory foam is typically made from polyurethane. This material moulds to the body and responds to heat being retained, making it hard to fall asleep and stay that way during the night due to the popular ‘hugging’ sensation that comes with basic memory foam options.

Open-cell memory foam 

We know that foam tends to trap heat, which is why experts have worked hard on creating an open-cell structure (holes in the foam) that allow airflow or gel-infused beads in order to promote cooling, making it more breathable and less heat-retaining.

Gel-infused foam 

There are brands that infuse traditional foam with gel to promote cooling. However, we can’t find solid proof that these infusions actually get the job done, making it a debatable choice, but overall, gel mattresses are purchased due to their cooling properties.

Traditional Polyfoam

We have basic and advanced polyfoams which are made from polyurethane. Like the memory foam one, the advanced polyfoam has been punctured to create a more temperature neutral environment, promoting better airflow.

Advanced Polyfoam

Advanced polyfoam is an improvement upon basic polyfoam that sleep experts have designed in recent years. This newer foam form contains small cells or air bubbles that increase the material’s breathability while reducing heat retention, making this option temperature neutral.

Bottom line

Generally speaking, mattresses are constructed with various materials, and some are more cooling and breathable compared to others that trap heat. For example, pocket sprung mattresses sleep the coolest, followed by latex and hybrid beds. The warmest mattresses are usually made entirely of traditional foam, but many advanced foam options today will keep you sweat-free at night. 

Overall, there are numerous reasons for the differences in temperature regulation among different mattress types, but the most important factor is airflow.

We hope we were able to answer the how and why when it comes down to ‘What are the most popular cooling mattress materials?’, and now it’s our turn to hear from you if any questions regarding the subject were left unanswered.
