Why Is Memory Foam Often Considered Less Cooling Than Latex?

This happens because memory foam is designed to conform tightly to the body’s shape, which can trap heat, while latex foam has a more open-cell structure that allows for better airflow and temperature regulation.

According to a study published in the Journal of Sleep Research, memory foam tends to retain body heat due to its viscoelastic properties, which cause it to absorb and hold heat rather than dissipate it. In contrast, latex foam is made from natural latex, which has a higher degree of breathability and is often treated with ventilation channels to enhance airflow, making it a better option for those seeking a cooler sleeping environment.

The underlying mechanism involves the materials’ thermal conductivity and the way they respond to body heat. Memory foam softens under heat, creating a “hugging” sensation but simultaneously reducing airflow around the sleeper. This can lead to an increase in temperature, especially for individuals who tend to sleep hot. On the other hand, the structure of latex foam allows it to remain more temperature-neutral, as it does not absorb heat to the same extent and encourages better air circulation, which helps to dissipate heat effectively.

What Mattress Designs Enhance Heat Dissipation?

The best mattress designs for keeping cool utilize various materials and technologies to enhance heat dissipation.
