Product Features & Specifications
The Lily mattress Dream Collection by Diamond is a blend of temperature-regulating technology responds to your body for a soothing atmosphere to sleep in every night. Hyper Conductive Sparkle Foam recalibrates your core temperature down to where it needs to be to fall asleep naturally, while airflow circulates to keep you comfortably cool throughout the night.
The Lily mattress Dream Collection by Diamond is finished with our Cool-Tencel Cover, another conductive fabric that moves heat away, allowing you to fall into a restorative sleep so you can wake up true to your nature.
