ESleep experts know that a cool mattress is the secret to a better, deeper night’s sleep. While the optimal sleeping temperature for most people is around 18 to 19 degrees, “hot sleepers” often find themselves stuck in a state of wakefulness because their bodies don’t cool down enough.
The KOZ-E CoolSleep brings the coolness back to your bed. With this cooling mattress topper, you can cool your mattress by up to 12 degrees. Stay cool through the direct contact of water on your skin instead of air heating, as with air conditioners.

Turns every night into a power nap.
Koz-e CoolSleep is a powerful life hack for anyone who wants to perform at their best. Do you hit the gym every day, often have to make important decisions, or is your schedule packed to the brim with meetings?

Especially if you lead a very active life and your body and mind are still “on” when you go to sleep, the temperature in bed can be the cause of restless nights. Sleep scientists have discovered that a constant skin temperature at night significantly improves deep sleep and minimizes the chance of waking up.
