4 Best Cooling Mattress In The UK 2021

When lockdown hit, the natural separation between work and play, day and night felt suddenly blurred. Working from home and our new casual uniform made selecting between these once hugely separate parts of our lives very difficult. In these times, the sleep schedules in everyone’s life had a great impact.

Few of us can afford to let go of a solid night of dozing. 95 percent of people identified a good night’s sleep as important to their general mood while 30 percent said they feel more anxious and irritated after a bad one. Thus indicating that sleep has a profound effect on our well-being and behavior.

While your mattress may not be the problem with your insomnia, it is possible that it is not doing you any favor. It is time for you to get a brand new mattress. While there are plenty of options that are designed to warm you up, electric blankets and whatnot, there are surprisingly few out there to cool you down. Until now.

Studies have proven that lower body temperature equals a better night’s sleep (it’s no wonder we love the cold side of the pillow) so invest in your slumber with my pick of the Best Cooling Mattress.

To help you get started, I have picked out some of the most popular cooling mattresses you can buy online. The prices below are only for a single variant in a particular mattress.

Types Of Mattresses For Cooling

There are many mattresses in the market that claim to keep you cool when you sleep, although there is a variation of the effectiveness in this area, some are more effective than others. When choosing a cooling mattress you should consider breathability, airflow, and types of layers within the mattress.


Latex is a naturally sourced material that is combined with springs or foam to create a supportive and comfortable mattress. Due to its elastic properties, it can contour to your body shape and allow for pressure relief.

Latex is an excellent choice for cooling as it can control temperature and can increase airflow, as many latex mattresses have been ventilated or have holes added. Natural latex is recommended over synthetic as it’s known to be more effective in trapping and dispersing body heat.

Memory Foam

Memory foam is made using polyurethane material that is sensitive to body heat and can also mold to your body shape. It is best known for providing a high standard of comfort and relieving pressure by distributing your body weight evenly.

Although memory foam mattresses are very popular they aren’t a great option if you are looking for a cooling mattress as they retain heat due to their dense material. Their best alternatives are advanced memory foam mattresses which include larger holes for better airflow and ventilation while maintaining the same comfort level. Another option could be an infused memory foam mattress that helps your body to cool down.


Polyfoam is similar to memory foam as they both tend to use polyurethane. But the polyfoam doesn’t trap as much heat as memory foam and is much better at regulating the temperature due to its elastic properties, which allows the mattress to push against your weight rather than compressing body heat.

The best alternative to standard polyfoam is open cell polyfoam that has larger air bubbles in it which promotes more fresh air to pass through it ensuring breathability and temperature regulation. Polyfoam is generally used on mattresses that are priced on the lower end of the spectrum, but they aren’t very durable and also aren’t eco-friendly.


Innerspring mattresses have been around for a while now and are therefore common in many homes. These mattresses are made with layers of springs and coils, and the more the number of springs, the greater is the support. This support is ideal for those people who prefer firmer mattresses with a springy feel.

As innerspring mattresses include spring coils within their layers, they conduct better airflow and are breathable. For improved comfort, some of the mattresses have memory foam in their layers. It is important to check that the layers are thin enough to distribute the airflow evenly.
