Often, yes—especially compared with an all-foam mattress. A king size hybrid mattress pairs a coil support core with comfort foams, and that coil layer can make a noticeable difference for hot sleepers because it allows more airflow through the bed than dense foam alone.
Gel-infused foam can also help by reducing heat buildup right at the surface where the body makes the most contact. Instead of trapping warmth as quickly, gel foam is designed to disperse heat and feel cooler when you first lie down. For many sleepers, that combination—airflow from coils plus a cooler-touch comfort layer—creates a more temperature-neutral night.
That said, not every “cooling” hybrid will feel equally cool. Performance depends on the full mattress build, including:
King size can be a bonus for hot sleepers who share a bed, since more space helps reduce concentrated body heat and makes it easier to move away from a warm spot.

Choose breathable sheets like cotton percale, linen, or bamboo viscose and avoid thick mattress pads that can block airflow. A lighter duvet or a cooling blanket can also help the mattress’ cooling features work as intended.
