Cooling Bedding Collection Independently Tested for a Cooler Night's Sleep
Heat build-up is one of the most common causes of restless, broken sleep. Our Cooling Collection is designed to address it directly, with fabrics that have been independently tested and verified for genuine cool-to-touch performance. Each product in this range uses breathable, moisture-wicking polyester fibres that help disperse warmth and keep your sleep surface feeling fresher for longer. Whether it's the pillow beneath your head or the protector across your mattress, every layer works to reduce overheating and help you settle into a calmer, more comfortable night. Hypoallergenic, easy care, and backed by a 5-year guarantee.

How cooling bedding works
Standard bedding fabrics absorb and retain body heat during the night, which is why the sleep surface gradually feels warmer as the hours pass. Cooling bedding uses fibres that actively disperse heat away from the body rather than trapping it, keeping the mattress and pillow surface feeling fresher for longer.
Belledorm's Cooling Collection uses breathable, moisture-wicking polyester fibres that have been independently tested and verified for cool-to-touch performance. The cooling properties are built into the fibre structure itself, not applied as a surface coating, so they are not diminished by washing. The range includes a cooling mattress protector that covers the full sleep surface and a cooling pillow that targets the head and neck - the two areas where heat build-up is most noticeable.
For a wider approach to cooler sleep using natural fabrics, Belledorm's bamboo sheets have natural moisture-wicking properties, and Egyptian cotton percale at 200 thread count has a crisp, open weave that allows more airflow than sateen. Pairing a cooling protector with a breathable natural sheet and a lower-tog duvet creates the coolest possible sleep environment.

Cooling bedding uses fabrics that are designed to reduce heat build-up at the sleep surface. Belledorm's Cooling Collection uses breathable, moisture-wicking polyester fibres that have been independently tested and verified for cool-to-touch performance. The fabrics help disperse warmth away from the body rather than trapping it against the skin, keeping the mattress and pillow surface feeling fresher through the night. This is different from simply using lightweight bedding - cooling fabrics actively work to lower the temperature at the point of contact.
A cooling pillow uses fibres that conduct heat away from the head and neck more efficiently than standard pillow fabrics. Belledorm's cooling pillow has a filling and outer casing made from moisture-wicking polyester that disperses warmth across a wider surface area rather than allowing it to concentrate in one spot. The head and neck generate a significant amount of body heat during sleep, so a pillow that actively reduces heat build-up can make a noticeable difference - particularly for people who flip their pillow to find the cool side.
Yes, particularly if you overheat at night. A cooling mattress protector sits between the fitted sheet and the mattress, and because it covers the entire sleep surface it has more impact on temperature regulation than a cooling pillow alone. Belledorm's cooling mattress protector uses independently tested cool-to-touch fabric that reduces heat retention across the full bed area. It also protects the mattress from moisture and wear in the same way a standard protector does - so it serves a dual purpose.
Yes. Night sweats cause moisture to build up between the body and the sleep surface, which then traps heat and makes the problem worse. Cooling bedding with moisture-wicking properties helps break this cycle by drawing perspiration away from the skin and allowing it to evaporate more quickly. A cooling mattress protector combined with a cooling pillow addresses the two main contact points. For the sheet layer, Belledorm's bamboo and Egyptian cotton percale fabrics also offer strong breathability and moisture management.
Yes. Belledorm's Cooling Collection is hypoallergenic, making it suitable for allergy and asthma sufferers. The moisture-wicking properties also help reduce the damp conditions in which dust mites thrive, adding a further layer of allergen management alongside the temperature regulation.
Cooling bedding works year-round, not just in summer. Body temperature rises naturally during sleep regardless of the season, and heated bedrooms in winter can cause just as much overnight overheating as warm summer nights. The fabrics regulate temperature rather than simply making the surface cold - they reduce excess heat without making you feel chilled. Many people who overheat at night find they benefit from cooling bedding in every season.
