Every person’s body temperature naturally rises and lowers throughout the day, with different temperatures corresponding with our sleep and how easily we fall asleep.

There are multiple studies on the Influence on human sleep patterns of lowering and delaying the minimum core body temperature by slow changes in the thermal environment and how that promotes better sleep at night. Overall, being too hot can disrupt your sleep and make it harder for you to fall asleep.

There are multiple ways to create a cool and relaxing sleeping environment, but today we will discuss the cooling mattresses and the difference between a good night’s sleep and a full night of tossing and turning. We’ll talk about products at different price points constructed with various materials and multiple positive impacts on the quality of your sleep.

How to choose a cooling mattress?

When you’re a hot sleeper, finding a cooling mattress might be your top priority, but that doesn’t mean you should ignore the other features a product has to offer. A bed that keeps you cool isn’t worth much, if it’s uncomfortable or not in your budget. Let’s discuss what factors you have to consider before making a purchase:

Cover & Temperature Regulation

One of the most critical factors, if you are worried about overheating, is the breathability of your mattress cover. Some covers are made from materials and fabrics that have excellent temperature regulation properties and wick away moisture, while others, not as much.

There are multiple options for materials, which can vary from natural to synthetic fabrics. Natural materials such as cotton will work better than polyester or viscose (synthetic) since they are more breathable, have moisture-wicking capabilities and prevent you from waking up in a puddle of sweat.

With that said, all layers can contribute to temperature regulation. For example, coil layers will provide better airflow, gel-infused options will help regulate temperature by absorbing body heat, and so much more.


Overall, the material a mattress is constructed out of dictates its properties and longevity. For example, low-quality memory foam will most likely develop permanent body indentations for less than a year. In comparison, a high-density polyfoam or traditional memory foam will last longer (around four or five years) and trap more heat. If you prefer fiberfill or feather, know that they have higher maintenance and require regular fluffing. They will usually last around 2 to 3 years.

For each type of mattress material, there are varying levels of quality available. The higher density of polyfoam is, the higher rate the foam tends to be. Higher quality polyfoam will be more durable and not as prone to developing body impressions. Natural latex mattresses tend to be of higher quality than synthetic ones.

In general, comfort levels range from 1 to 10, with one being the softest and ten being the firmest. The firmness scale of a product isn’t usually related to its cooling ability, but it’s still essential for the quality of your sleep. The industry standard varies between 6 to 7 on the scale, which is considered a medium to medium-firm.

For example, lighter sleepers and side sleepers are best suited for a softer choice, whereas stomach sleepers and heavier individuals should choose a firmer item. Put simply, the heavier the sleeper, the more they will sink, leading to increased heat retention, which is the opposite of what you want, so make your choice wisely.


There are many types such as memory foam, innerspring, latex, hybrid, pillow top and even natural wool mattresses. Memory foam tends to trap heat, if not infused, whereas pocket sprung, wool and hybrid mattresses provide a more temperature neutral atmosphere because of the airflow passing through the coils.

Pressure Relief

Pressure relief is usually associated with memory foam due to its close-conforming abilities. However, foams can often contribute to your body overheating. If you want to stay away from memory foam, you can try latex since it has pressure-relieving properties similar to it while being more breathable.

Edge Support

Edge support generally refers to the firmness of a mattress’s edges when a person gets in and out of bed. By having strong edge support, you can take advantage of the whole surface of your bed without feeling like you will fall off.


Just like anything else, the price can vary widely depending on the materials and quality of a mattress topper. High-quality options will start at a few hundred pounds and get up to a few thousand. The saying you get what you pay for is often true, which is why you should look at all the possible products before setting a budget. With added price comes higher quality and better longevity.

Typically, mattresses sold online are less expensive since the manufacturer doesn’t have to pay for showrooms and additional staff.

What are the best cooling mattress materials?

best cooling mattress materials

As we mentioned above, 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:

  • Latex – 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.
  • Innerspring – coils and springs are often made from steel. They offer great support and excellent airflow throughout the entire mattress, which cools the comfort layers above.
  • Traditional memory foam – is typically made from polyurethane. This material moulds to the body and that responds to heat being retained, making it hard to fall asleep and stay that way during the night.  
  • Gel-infused foam – there are brands that infuse traditional foam with gel to promote cooling. However, we can find solid proof that these infusions actually get the job done.
  • 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.
  • 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.

Bottom Line

If you’re a hot sleeper, attempting to be cool shouldn’t be a task you have to conquer every night. There are many cooling options at different price points that may help you with temperature regulation while providing excellent comfort and support.

All of the mattresses we listed above have great customer reviews and are well received. We hope you were able to find what you were looking for in our guide when it comes to the best cooling mattress the market has to offer.
