TECHNICAL INFORMATIONS
The principle of a self-inflating mattress
A self-inflating mattress consists of an airtight envelope glued to an open cell foam in which the air circulates. When you unfold your mattress, it will return to its original shape and thickness (2.5 cm for the MT100 mattress) and fill with air. However, it requires some mouth inflation so you can adjust it to the pressure level suitable for you. Self-inflation is more or less noticeable depending on the thickness of the mattress.
Easy inflation/deflation
When using your mattress for the first time, unroll it, open the valve for 24 hours on a flat surface, then inflate it and leave it for 24 hours, valve closed, under pressure. Then you can store it away again. While trekking, take out and unroll your mattress as soon as you set up camp, valve open to facilitate pre-inflation. A self-inflating mattress inflates to about 60 to 70% on its own. You will need to blow up the rest yourself, so you can adjust the pressure to your desired comfort level.
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.
ADDITIONAL SUSTAINABLE DEVELOPMENT INFORMATION
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 this product’s CO2 emissions compared to the previous model.
How to repair a leaky mattress
An inflatable mattress is not puncture-proof but it can be repaired!
For outdoor use, as much care as possible should be paid to its set-up and handling. You can repair your mattress with the following kit: https://www.decathlon.co.uk/p/kit-of-6-self-adhesive-repair-patches-for-inflatable-mattresses/_/R-p-311504?mc=8557113
It has the same features and performance while minimising your environmental impact.

ProcessDope dyed
70% of the fabric color is made by dyeing the yarn at the source
Dyeing textiles requires lots of water but also leads to lots of water waste generated in dyeing vats. To reduce this environmental impact, we choose solution dyeing, which integrates colour pigments when manufacturing the thread.
