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
What can I do for my partner who sleeps too hot in bed?
If your partner feels like a "human oven," standard advice like opening a window or buying cotton sheets often isn't enough. To truly fix the problem, you need to tackle the heat where it starts: at the sleep surface. Here is what you can do Use a dedicated cooling mattress topper like the kOZ-E CoolSleep. Because it’s 90cm wide, you can cool your partner’s side down to 12°C without freezing yourself out of the bed. Instead of just "breathable" fabrics that eventually warm up, kOZ-E uses water-cooling technology to actively neutralise and move away excess body heat all night long. Help your partner's body reach the optimal sleep temperature of 18°C-19°C. This stops the tossing and turning and prevents those exhausting night sweats. By regulating the temperature on their side, you can finally stay close and enjoy more hugs without the discomfort of overheating.
