Common cooling features include phase-change or cool-touch surface fabrics, vented mesh sides for airflow, gel-infused top layers, breathable open-cell comfort foams, and 360° airflow systems to dissipate heat and moisture.
Listings mention motion-isolating designs such as pocketed or barrel pocketed coils and memory-foam comfort layers that help limit motion transfer.
