Best Mattresses for Hot Sleepers

To pick the best mattresses for hot sleepers, Regan identifies the mattresses that are best at keeping cool in our heat-trapping lab test. He then chooses models based on their Overall Score, which is determined by all of our mattress testing and member surveys. The two-step selection process ensures that the chosen mattresses, listed below in alphabetical order, provide support and stability without retaining heat. In our mattress ratings, you can filter for mattresses that won’t make you feel hot to see how they fare for other criteria.

Our mattress tests cover support for back and side sleepers, durability, and stability. To test whether a mattress traps heat, we place a copper plate warmed to 98.6° F on each mattress, simulating average body temperature. Over an 8-hour period in a temperature-controlled room, we measure how much energy the plate uses to maintain its temperature. If the mattress keeps heat in, the plate will need less energy because it won’t need to generate additional heat to keep the plate warm. We also include brand ratings on mattress comfort and owner satisfaction from our member surveys on nearly 67,000 mattresses.

These mattresses earn high marks for support, durability, and stability, and—based on our lab testing—trap less heat than the other mattresses we’ve rated.
