What to Look for in a Cooling Mattress
✅ 1) Hybrid airflow beats foam heat
Coils create airflow. Most hot sleepers do best with hybrid mattresses.
✅ 2) Avoid “deep sink” if you sleep hot
The more you sink into foam, the more heat gets trapped.
✅ 3) Cooling covers help (but aren’t everything)
A cool-to-touch cover helps initially, but airflow + materials matter most.
