Best cooling mattresses for hot sleepers UK

·10-min read

When lockdown hit, the natural separation between work and play, day and night all felt strangely blurred. Working from home and our new casual uniform made discerning between these once hugely separate parts of our lives oddly difficult. In these times, sleep was the first thing to go.

Even as life is returning to a semblance of normality, it still feels like there’s a lot interfering with our slumber patterns - stress, uncertainty and weather-dependent, heat.

While we Brits complain all winter in hopes for a ray of sunshine, when the warmer weather arrives, it brings with it a whole new set of woes. For hot sleepers, it’s nothing short of a nightmare as you toss and turn around looking for a patch of coolness to lull you into slumber.

Few of us can afford to forgo a solid night of dozing. According to a survey commissioned by Woolroom and YouGov, 95 per cent of people identified a good night's sleep as important to their general mood, while 30 per cent said they feel more anxious after a bad one. It can have a profound effect on our wellbeing and behaviour.

While your mattress may not be the main cause of your sleeplessness, it is possible that it's not doing you any favour - especially old memory foam options that were crafted to be dense and prevent airflow.

While there are plenty of products designed to warm you up - electric blankets, throws - there’s surprisingly few out there to cool you down. Until now.

Take night sweats out of your bedtime routine with the new technology of modern mattresses. A godsend when the heatwave hits, these specially-designed cooling mattresses are layered with open-cell structures, ActiGel or proprietary layers to maximise breathability and absorb body heat - all while keeping you comfortable and supported. Pocket spring mattresses tend to have built-in ventilation based on the way in which the coils are placed, while materials like wool and bamboo are moisture-wicking in nature.

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 our pick of the best cooling mattresses.

Ergoflex 5G Mattress

Giving hotel room beds a run for their money, Ergoflex makes some of the best mattresses in the biz.

Not to be confused with the cellular network, the 5G model combines a premium proprietary foam promising support and comfort “from head-to-toe”. The five layers each add an unmissable quality that relieves pressure on the body and encourages you to drift off into a sound slumber.

First and foremost, the Tencel outer cover works to protect the mattress itself but it does so much more. It has a vented construction at the ends with 3D mesh panels to disperse the heat so you won’t feel hot and bothered in the night. The top memory foam layer contours to your body but just the right amount so as not to affect your partner if you move around.

At the core, breathability is the utmost concern. At 9cm, the trademarked Cool-Sleep layer creates an airflow to stop the build up of heat. This is done through an open-cell memory foam that prevents the retention of hot air more efficiently than any previous model.

Ideal for aches and pains, the mattress has orthopaedic pressure-relief. It is also hypoallergenic and anti-microbial and there’s a 10-year warranty.
