Memory foam beds are not typically the first recommendation for a hot sleeper because the materials run warmer than most other mattresses. If you tend to sleep hot, a mattress expert would likely point you in the direction of a hybrid or innerspring mattress. However, just because memory foam mattresses trap more heat does not mean that they’re a terrible mattress option for hot sleepers. Alternative materials like gel, latex and plant-based are now used in memory foam beds to create a cooler sleeping experience.
