Each mattress material and design have a different way to transfer body heat away from the sleeper. Memory foam mattresses of today have gel infused foam layers to deal with body heat, whilst maintaining great contour support for the sleepers back.

Spring mattresses have a natural gap created at the bottom when the comfort layer is fitted on top of the coil. This gap helps to circulate body heat so that heat does not build up throughout the night. Hybrid mattresses, which have both memory foam and springs use a combination of gel infused layers and springs to control overheating. Materials such as latex have a cool sleep experience, but the poor motion isolation, price-tag for natural latex and odor that the material produces may become a disturbance.

Although there is no perfect answer to which mattress design or material is superior for quality sleep, each mattress manufacturer uses a different combination of these variables to reach the end goal of comfort and support. For the person buying the mattress, you should be asking whether this design or whether this material fits my sleep position and am I going to be disturbed by movement or temperature. If you already have an answer, I believe you already get a gist of how to choose a mattress that fits you.
