slily 7-Zone Cooling Hybrid Mattress - Small Double
£179.99
Sleeping too hot is one of the most common sleep complaints in the UK. Whether it is caused by memory foam trapping heat, a warm bedroom, or simply running hot naturally, the right mattress can make a significant difference. We have scored every mattress in our database on cooling performance, factoring in gel technology, open-cell foam, breathable covers, and spring airflow, to find the ones that will keep you comfortable all night.
Traditional memory foam is the biggest culprit. Its dense, closed-cell structure traps body heat and restricts airflow. While memory foam excels at pressure relief, it can raise the surface temperature of the mattress by several degrees over the course of a night.
Body weight, room temperature, bedding, and even your partner can also contribute to overheating. But the mattress itself is the foundation, and choosing one with proper cooling technology can reduce night sweats and improve sleep quality significantly.
Gel-infused foam contains gel beads or a gel layer that absorbs and redistributes heat. It does not actively cool, but it prevents the heat build-up common with standard memory foam.
Open-cell foam has a more porous structure that allows air to circulate through the material. This is one of the most effective passive cooling methods in foam mattresses.
Pocket springs naturally promote airflow between the coils, which is why hybrid mattresses tend to sleep cooler than all-foam options.
Breathable covers made from bamboo, Tencel, or moisture-wicking fabrics help draw sweat away from the body and allow it to evaporate.
If cooling is your priority, hybrid mattresses are the safer choice. The spring layer provides natural ventilation, and most hybrids use a thinner foam layer that retains less heat. If you prefer the contouring feel of memory foam, look for gel-infused or graphite-infused options with an open-cell structure.
Yes. Mattresses with gel foam, open-cell construction, and spring-based ventilation measurably reduce surface temperature compared to traditional memory foam. You will not feel cold, but you will avoid that uncomfortable heat build-up.
Hybrid mattresses with gel memory foam or latex comfort layers tend to sleep the coolest. The pocket spring base promotes airflow while the cooling foam layer prevents heat retention.
A gel memory foam or cooling topper can help, but it works best on a mattress that already has decent ventilation. Putting a cooling topper on a thick, heat-trapping foam mattress will have limited effect.
