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."
