Discover our range of British-made cooling mattresses, trusted by hot sleepers across the UK for relief from overheating and night sweats. Each mattress is engineered with our 30x breathable Sleep Resonance Foam®, moisture-wicking fabrics, and air-regulating pocket springs — keeping your body temperature balanced from the moment you lie down.
Why Hot Sleepers Choose Sleep Harvester
Overheating at night disrupts your sleep cycle and leaves you exhausted by morning. Our cooling mattresses are designed from the inside out to draw heat away from your body, promote airflow, and regulate temperature — without complex heating-cooling systems or gadgets.
30x Breathable Sleep Resonance Foam®
Our proprietary open-cell foam is engineered to be 30 times more breathable than standard memory foam, allowing heat to escape rather than build up. The result is a cooler, fresher sleeping surface that responds to your body without trapping warmth.
Cooling Hybrid & Foam Options
Whether you prefer the contouring feel of a cooling foam mattress or the added support and airflow of a hybrid cooling bed mattress, our collection covers every preference. Choose from soft, medium, or firm feels — all designed to deliver pressure relief, spinal alignment, and a cooler night's sleep.
Moisture-Wicking Fabrics & Breathable Covers
Every mattress in this collection is finished with a moisture-wicking, breathable cover that draws perspiration away from the skin. Combined with our internal cooling layers, the surface stays fresh and dry throughout the night.
British-Made Quality You Can Trust
All Sleep Harvester cooling mattresses are crafted in Britain to exacting standards, backed by up to a 10-year guarantee. Free UK delivery is included, and our team is on hand to help you find the right feel for your sleep style.
