KOZ-E

Wake up refreshed

Cold feet in winter, shivering as you fall asleep, or waking up in a chilly bed? KOZ-E Sleep changes that. Instead of wired heating, KOZ-E uses water. With the whisper-quiet control unit by your bedside, you set your ideal bed temperature in seconds.

Even warmth, no electronics where you sleep

Flat, flexible water channels distribute gentle warmth beneath a soft, premium, washable top layer. The water tank warms the mattress — without any electronics in the sleeping surface. It’s simple, safe-feeling and remarkably comfortable.

The luxury of the right sleep temperature
Finding the right bed temperature can help you fall asleep faster, sleep deeper and wake up less often. KOZ-E Sleep lets you fine-tune warmth to your body.
