The Best Cooling Mattresses for Hot Sleepers
Regulating your body temperature during the day is pretty easy. However, at night, things can become more complicated. And if you suffer from hot flushes, night sweats, or simply prefer a cooler sleeping environment, just opening a window or throwing off the covers doesn’t cut it. So, you need to look at cooling mattresses.
Getting too hot at night can interrupt your sleep cycle, leading to poor quality sleep. Over a prolonged period, this can start to affect both your physical and mental well-being. It’s important, especially in the summer, to do everything you can to regulate your body temperature at night. One thing that can really make a difference is a cooling mattress.
What is a cooling mattress?
A cooling mattress is referred to in the industry as a ‘passive cooling system’. It’s a mattress that’s designed to create a cooler, fresher sleeping environment. This is either through the use of gel layers, cooling materials such as bamboo, or increased airflow and ventilation.
The trick with a cooling mattress to achieve the best level of cooling is to combine it with simple measures such as opening a window to increase airflow. If you’re still suffering from hot flushes and night sweats, it may be a good idea to invest in a small portable AC unit or just a simple fan. This can move cooler air across you as you sleep.
The advantage of cooling mattresses is that they really are silent, and designed to help you regulate your body temperature for a more comfortable night’s sleep.
How do cooling mattresses work?
Cooling mattresses use a variety of materials to help keep the temperature down.
Gel foam is the most popular and commonly used mattress type for cooling mattresses. Tiny gel beads are inserted into a layer of memory foam. These gel beads stay cooler for longer, creating a more stable temperature even in hotter weather. Other mattresses use gel-infused foam rather than beads, but the effect is the same.
Gel foam is also used in gel mattress toppers and pillows, allowing you to adapt your sleeping environment to suit your needs. Some people only want that ‘cool side’ of a pillow to help them get to sleep. Others may need more help controlling their body temperature at night to avoid night sweats or disturbed sleep patterns.
These are memory foam mattresses that have been designed to incorporate air channels into the design. This allows a greater degree of airflow through the mattress. While a traditional open coil or pocketed sprung mattress will deliver better airflow, open-cell mattresses allow you to have all the comfort of a memory foam mattress. But, with more control over the ambient temperature.
Using natural fibres such as silk, cotton and bamboo helps to create a cooler feel. Pure wool is also breathable, allowing the air to flow through the layers of fibres within the interior of the mattress. Team them up with pure cotton sheets and pillowcases and you have a much cooler sleeping environment. This is also naturally hypoallergenic.
What are the best cooling mattresses for hot sleepers?
There are two main groups of mattresses – pocket sprung mattresses and memory foam mattresses. Within these two groups are a variety of subsections, such as latex mattresses, hybrids (that are made from both layers of memory foam and have a sprung core), and ‘cool gel’ mattresses, which will be of particular interest to hot sleepers.
You’ll also need to factor in a few other points when you’re trying to choose the best mattress, such as how you sleep (on your back, your front or your side) and how big you are. Also, whether you share your bed with a partner, and the level of firmness and support you want.
You’ll also need to consider things such as whether or not you suffer from a bad back. If you want to know more about picking an option that suits you, take a look at our Guide to Choosing the Right Mattress.

What is the best mattress for hot side sleepers?
The position you sleep in is a key factor in deciding what type of mattress to choose. For side sleepers, you need a combination of support and cushioning to keep you in a ‘neutral position’ (where your spine is in line without dipping at the neck or hips). And a surface that prevents pressure points from forming.

- A breathable knitted cover that’s soft, cool, and comfortable
- Single-sided, so it’s easy to maintain.
What should you look out for with a cooling mattress?
Key features to look out for on a cooling mattress include;
- Air vents – usually found built into sprung mattresses and hybrid designs, air vents are found at the side of the mattress and are open so that they allow air to flow into and out of the mattress. This creates a healthier environment too, as it prevents moisture build-up in the centre of the core, which can, in turn, encourage dust mites to take up residence.
- Breathable cover – the use of natural materials such as wool and silk creates a softer feel, but it’s not just used for aesthetics. Natural materials are breathable and allow that all-important air circulation to flow through, giving you a cooler sleeping surface.
- Gel layers – Cool-Gel layers incorporated into memory foam and latex mattresses are a recent innovation. But if you really want to go down the foam mattress route, they’re a real bonus if you’re a hot sleeper.
- Good support – Make sure you pick the right level of support when you’re choosing your mattress. If you suffer from a bad back then comfort and support are just as important as staying cool. Find out more with our Sleep tips for a bad back Guide.
