What is the R-Value?

  • The R-Value is a measure of the thermal insulation. It measures the ability of a mattress to retain or prevent heat from escaping from a warm body (human body) to a cold floor.
  • The higher the R-Value, the better the insulation of the mattress.
  • Please note that the R-Values can be added; this means that you can use two mattresses and add their R-Values.
  • All our mattresses are tested to standard ASTM F3340-18.

What R-Value for what use?

  • R-value from 0 to 1.9: Hot season (summer) only
  • R-value from 2 to 3: 2 or 3-season (spring-summer-autumn)
  • R-value from 3 to 4: 4-season
  • R-value of 4.5 and higher: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)

Comfortable postural support

  • Sleep on aluminised side, facing the sleeping bag with foam side on the ground to minimise losses of body heat.
  • For a foam mattress, this mattress offers a greater level of comfort thanks to its design and the depth given to the foam by the mould. This specific design allows for 2 cm mattress thickness, giving home comfort and real postural support.
