Sleep Environment™

Temperature plays a crucial role in sleep regulation. To fall asleep, the core body temperature must decrease by approximately 1°C. Each person’s body has a different tendency to make these adjustments and adapt to the temperature of their sleep environment.

Onethird Sleep Environment™ is an intelligent mattress overlay that accurately measures users’ core body temperature, uses advanced AI algorithms to determine their unique optimal bed temperature, and adjusts the temperature accordingly.
