Manage Your Body Temperature Regulation Disorder: Take Back Control Over Your Nightly Rest
Tired of the 'Thermal Rollercoaster' stealing your night rest?
You go to bed hoping for rest, but your body has other plans. Within hours, you’re trapped in the 'Thermal Rollercoaster'. First, a wave of intense heat that leaves you drenched and tossing aside the blankets. Then, as the sweat evaporates, a sudden, piercing chill that forces you to cover up again. This isn't just 'feeling warm'—it is an inability to control your body thermostat during sleep, and it is exhausting.

Here's what our community says after more than 6 months of CoolSleep
"Top product This mattress has helped me a lot with warmth in winter and coolness in summer. And that has given me a much better sleep pattern. I wouldn't want to be without it.😊👍"
Anneke
"Better nights with the mattress cooler Last year, I bought the mattress cooler. I'm someone who gets hot quickly at night (very quickly) and it gets incredibly hot in my house in the summer. The mattress cooler is a real godsend. Even my Whoop shows that I sleep and recover better when I sleep with the mattress cooler. Easy to use and reasonably quiet. Highly recommended!"
Nikita
"I've had the KOZ-E Sleep mattress topper for 9 months now and I'm really happy with it. What an improvement! No more suffering from the heat at night; it keeps the temperature just right. I can recommend it to everyone."

What does a sleep expert say?
"As a sleep researcher I know that being too hot or too cold is one of the main issues for people to sleep well. Especially sleep onset latency is negatively affected; it takes longer to fall asleep if it is warm or cold in bed. That’s why in 2023 I’ve tested the KOZ-E sleep. We see that the product performs well from a functional point of view; both cooling and warming works well and is comfortable. It can help you fall asleep more easy and better during a heatwave or a cold winter."

CoolSleep Mattress cooler FAQ
How does the CoolSleep mattress help keep me cooler if I have body temperature regulation disorder ?
When you have a body temperature regulation disorder, your brain's internal thermostat fails to signal your body to cool down or warm up correctly. The CoolSleep mattress cooler acts as an essential external regulator.
Instead of relying on your body’s inefficient signals, our system uses high-grade water circulation to maintain a constant, pre-set temperature. By actively absorbing excess heat directly from your skin, it compensates for your body’s inability to balance itself. This provides the thermal stability your biology can no longer provide, allowing you to stay in a deep, restorative sleep state all night long.
