Technical information

Why is your inflatable mattress white?

Dyeing has a strong impact on the environment, which is why the fabric of your air mattress is not dyed. This underlines its technicality and signs its avant-garde character. But above all, it reduces its environmental footprint, by reducing its CO2 emissions by 13%.

This mattress is part of the Minimal Editions - Undyed range, which also includes an MT900 0°C Duvet sleeping bag and an MT900 2P tent.

Volume and folded size

Folded dimensions Ø 10 cm x 22 cm.
Volume: 1,7 litres.

Easy inflation/deflation

The simplest way to fold without damaging your mattress is to fold it in four widthways, then roll it up.

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.

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).
