CoolSleep Series

The CoolSleep™ Series: Advanced Bed Cooling Systems

The CoolSleep™ Series is engineered to help you fall asleep faster and stay in a deep sleep, even during the hottest nights. Do you often find yourself tossing and turning before finally drifting off, or do you regularly wake up sweating during the night? This often happens because your body temperature isn’t optimal for rest. Whether it is caused by stress, a busy mind, or late-night exercise, an elevated core temperature can prevent you from reaching the deep sleep cycles your body needs.

With the KOZ-É Cooling Sleep System, you can leave those restless nights behind. Our collection offers active solutions to cool your bed down to as low as 12°C (54°F). While the optimal sleep temperature for most people is around 18-19°C, "hot sleepers" often go to bed while their body is still in an active state, failing to cool down naturally. The CoolSleep™ Series quickly brings your body to the ideal temperature for your specific situation. This results in faster sleep onset, more intense recovery, and fewer nighttime interruptions.

Within the CoolSleep™ collection, you have total control over your sleep climate with simple bedside operation. The whisper-quiet unit circulates chilled water through the system’s fine micro-channels. This ensures there is no electricity or radiation under your blankets—just the natural, soothing power of water cooling.

Keep Your Body Cool and Fresh with Our Series

With a KOZ-É Bed Cooling System, you can sleep as cool as you desire. Using the quiet control unit next to your bed, you easily set your ideal temperature. Our premium systems are equipped with breathable mesh technology for optimal ventilation throughout the night. This not only assists in cooling but also actively prevents night sweats.

Never wake up in a damp bed again. By regulating your sleep temperature with the CoolSleep™ Series, you keep your mattress clean and dry. This advanced thermal regulation also helps maintain the relative humidity in your bed at an ideal level. Every morning, your bed feels fresh, and you wake up with positive energy, ready for a new day. Control is at your fingertips: use the convenient remote to adjust settings without getting up. You can rely on the compact and dependable technology of the CoolSleep™ Series every single night.

Fall asleep faster

Helps you fall asleep more easily on hot nights, after exercise and when you’re stressed. For most people, the ideal sleeping temperature is around 18 to 19 degrees. People who tend to get hot in bed often go to bed whilst their body is still in ‘awake’ mode and doesn’t cool down naturally. CoolSleep brings your bed and body to the right temperature so you can fall asleep quickly.

Sleep more deeply

With the right temperature in bed, you’ll sleep more deeply and wake up less often. With CoolSleep, you can adjust the temperature continuously from 12 to 48 degrees, tailored to your body. A good night’s sleep has many benefits: it improves your immune system, your memory and your ability to concentrate, amongst other things.

Prevent night-time sweating

No more wake up in the middle of the night drenched in sweat. Keep your mattress clean and dry by maintaining a sleeping temperature in bed that suits you. Temperature regulation also helps to keep the relative humidity in bed at an ideal level. Every morning, your bed will feel fresh and you’ll wake up full of positive energy.

Wake up feeling fit and refreshed

Uninterrupted nights of deep sleep are essential for a healthy life. You wake up every day feeling refreshed and full of energy, ready to make the most of life. Sleep scientists have discovered that maintaining a constant skin temperature throughout the night significantly improves deep sleep and minimises the likelihood of waking up.
