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.
