Beat the Heat with Advanced Cooling Technology

From £309 · Fast UK Delivery · Up to 10-Year Guarantee

Our cooling mattresses are engineered to help maintain a comfortable sleeping temperature from the moment you lie down. Designed for people who naturally sleep hot, each mattress combines breathable materials, moisture-wicking fabrics, and advanced support systems to create mattresses that sleep cool without relying on external cooling devices or mattress cooling systems.

If you're looking for the best mattress for hot sleepers, our range offers a balance of cooling comfort, pressure relief, and full-body support.

Why Hot Sleepers Choose Sleep Harvester

Overheating during sleep can interrupt your natural sleep cycle and reduce sleep quality. A high-quality cooling mattress helps disperse body heat, improve airflow, and reduce heat retention throughout the night.

Our mattresses are designed to:

• Promote airflow for cooler sleep
• Reduce heat build-up commonly associated with traditional foam mattresses
• Wick away moisture and perspiration
• Support healthy spinal alignment
• Deliver pressure-relieving comfort without trapping excess warmth

For sleepers seeking additional posture and back support, explore our orthopaedic mattresses collection.

30x More Breathable Sleep Resonance Foam®

At the heart of our collection is Sleep Resonance Foam®, engineered to be up to 30 times more breathable than traditional memory foam.

Unlike standard foam that can retain heat, our open-cell structure encourages airflow and allows warm air to escape. This creates a cooling memory foam mattress experience that delivers contouring comfort while helping maintain a comfortable sleeping temperature.

For sleepers who enjoy the feel of memory foam but want a cooler night's sleep, our memory foam cooling mattress designs offer the ideal balance of support and breathability.

Temperature Regulating Mattresses for Cooler Sleep

Every mattress in this collection is designed as a temperature regulating mattress, helping your body maintain a more consistent sleeping environment throughout the night.

Breathable comfort layers work alongside responsive support systems to improve ventilation and reduce overheating. This makes our mattresses particularly suitable for hot sleepers, warm bedrooms, and anyone searching for the best cooling mattress for year-round comfort.

Cooling Hybrid and Foam Mattress Options

Everyone sleeps differently, which is why our collection includes both cooling foam and hybrid cooling mattresses.

Choose from:

• Cooling memory foam mattresses for contouring comfort
• Hybrid cooling mattresses with airflow-enhancing pocket sprung mattresses
• Medium, firm, and softer comfort options
• Double, king size cooling mattress, and super king sizes

Whether you prefer the pressure-relieving feel of foam or the enhanced airflow of a hybrid design, you'll find a cooling mattress tailored to your sleeping style.

Moisture-Wicking Covers and Breathable Materials

Each mattress is finished with a breathable, moisture-wicking cover that helps draw heat and perspiration away from the body.

Combined with our internal cooling layers, these materials help create a breathable mattress that feels fresher, drier, and more comfortable night after night.

British-Made Quality You Can Trust

All Sleep Harvester cooling mattresses are proudly made in Britain using carefully selected materials and rigorous manufacturing standards.

Every mattress is backed by up to a 10-year guarantee and includes fast UK delivery, giving you confidence that you're investing in long-lasting comfort and support.
