Different mattress types cooling performance
#1: Innerspring Mattresses
These beds make the best mattresses for hot sleepers. A bulk of the support core of innerspring mattresses consists of springs. The space between these springs promotes airflow, making them naturally cool.
#2: Hybrid Mattresses
Hybrid mattresses have a significantly thicker comfort section made of foam (memory foam, latex, or polyfoam) and a coil-based support section. As with innerspring, the gaps between the coils allow air circulation making these mattresses fairly temperature neutral. However, these mattresses may still retain heat if the comfort section comprises a thick layer of memory foam.
#3: All-foam Mattresses
All-foam mattresses are the most notorious for heat retention. Their poor performance is mainly attributed to the foam's general structure, which inhibits the free airflow.
Heat retention in all-foam mattresses is affected by two things: the foam's density and the firmness. Generally, a mattress with more contouring is going to retain heat the most. This explains why low, and medium-firm memory foam beds are the biggest culprits in matter heat retention.
Firm foam beds tend to hold you aloft and don't create air pockets that trap heat around you. Sleeping on the bed (as opposed to sinking in the layers) also means that there's a lot of air flowing around you, thereby dispersing body heat.
Of all-foam mattresses, latex makes a popular choice for people who sleep hot at night. Latex mattresses are naturally breathable and are comparably better at regulating heat than visco-elastic mattresses. Latex foam gets even better at air circulation when used in a hybrid setup, as it's the case with the Saatva latex hybrid mattress.
