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)

Tips for sleeping well on your mattress

Once you are lying down, remember to adjust the inflation pressure of the mattress by slightly pressing the IN valve (open cap). A mattress that is too hard is often synonymous with discomfort.

Silicone patches on the top of the mattress are designed to reduce the sliding of your sleeping bag on the mattress.


Textile dyeing requires a lot of water but also produces waste water from the dye baths.
To reduce the environmental impact of this model, we chose to use a dyeing process called "bi-ton" which involves dyeing one out of every two yarns. This dyed yarn is also made from a bulk dyeing process which incorporates the colour pigments from the yarn manufacturing phase onwards.This process reduces the CO2 emissions of this product.

How to repair a leaky mattress

An inflatable mattress is not puncture-proof but it can be repaired!
When using it, take every care when installing and handling it.
In the event of a problem, we recommend using self-adhesive repair patches (ref: 8584596).
