Our new and exclusive Sleepsmart™ Bedding with Fresh Zone technology continuously adjusts to help maintain a climate of personal comfort at the ideal 37.5° Celsius all night long, so you can wake up rested and refreshed.
- Our Fresh Zone™ technology and 37.5® fibers work together to prevent odor and eliminate bacteria-driven allergens in the fill.
- Fill is made of 80% polyester and 20% 37.5® performance polyester.
- As you sleep, temperature and humidity starts to build-up and becomes trapped in your sleep environment or microclimate, this is where you start to feel overheated and uncomfortable and eventually disrupting your sleep as you rollover to find a cool spot. 37.5® technology releases excess heat and humidity, preventing it from becoming trapped within your microclimate.
- Body heat activated performance, comfort personalized to each sleeper's need for warmth.
- Moves heat away before sweat can form, minimizing swings in body temperature so you stay asleep longer.
- Works immediately, and continuously while you sleep to either trap heat when you're cold or evaporate excess heat and humidity when you’re warm.
- Sewn through box quilting prevents fill from shifting & has corner loops for easy attachment to your duvet cover.
- Sleepsmart™ is designed to work as a total system; it’s performance increases with additional Sleepsmart™ layers.
