Thermal protection and heat

Since the beginning of 2020, a new standard has been validated to assess the level of insulation of your mattress: standard ASTM F3340-18.

This standard measures the capacity of the mattress to retain or return body heat in order to avoid its loss and therefore provide you with thermal comfort.
