I appreciate that the inflator valve has a non-return valve. So it is much easier to inflate.

Honestly it's a top product, even sleeping on my side I was isolated from the hard ground and I slept like a baby! 👍👍

practical but fragile product

The mattress is at first glance perfect for a touring hike in summer. Its weight and size are acceptable. The big downside, after 8 days of use, a large dent formed in the middle of the mattress making it very uncomfortable for the end of the hike and unusable thereafter.

good slightly small mattress for adults

Very good comfortable mattress, not long if you want to inflate it

Additional Product Information


Foam: 100.0% Polyurethane ; Floor mat: 50.0% Thermoplastic Polyurethane, 50.0% Polyester ; Main fabric: 50.0% Thermoplastic Polyurethane, 50.0% Polyester ; Carry bag: 100.0% Polyester

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 regain its shape and thickness (2.5 cm for this 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) onlyR-value from 2 to 3: 2 or 3-season (spring-summer-autumn)R-value from 3 to 4: 4-seasonR-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: 8557113).For more information, copy the following link into your browser:

Product testing

All our mattresses undergo mechanical performance and resistance tests to guarantee you the best night's sleep and recovery (thermal and abrasion resistance, etc.). We also carry out several field tests in real-life conditions.

Storage instructions

In order to improve the durability and reliability of your product, store it laid out flat with the valve open in a dry place away from extreme temperatures.
