Hi Friend,

Do you often wake up too warm during the night? A cooling mattress might help reduce heat buildup and improve airflow while you sleep.

Cooling mattresses are designed to reduce heat retention and improve airflow using materials and structures that help regulate temperature while you sleep.

Several technologies help cooling mattresses maintain a cooler sleep surface.

Breathable Cover Fabrics: Help wick moisture and circulate air.
Gel-Infused Foam: Help disperse body heat and reduce heat buildup inside foam layers.
Phase-Change Materials (PCM): Absorb and release heat to maintain a more stable temperature.
Open-Cell Foam Technology: Features small air passages that improve airflow through the foam and help reduce heat retention.
Airflow Through Coil Systems: Allow air to circulate more freely through the mattress core.

Small design differences like these can completely change how a mattress feels overnight.
