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 the mattress, it will return to its original shape and thickness (2.5 cm for the trek 500 mattress) and fill with air accordingly. 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 to assemble and fold down
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 help pre-inflation. A self-inflating mattress inflates to about 60 to 70% on its own. To complete the process, mouth inflation is required to adjust the pressure to suit you.
Thermal properties and warmth
Since the beginning of 2020, a new standard has been validated to assess the level of insulation of your mattress: standard ASTM F3340-18. This standard measures the capacity of the mattress to retain or return body heat in order to avoid its loss and therefore provide you with thermal comfort. Thermal insulation thanks to the foam. The R-Value R-Value standard ASTM F3340-18: 2.7 (measured by an independent laboratory)
Thermal properties and warmth (2)
The R-value expresses the thermal performance and resistance of the mattress. The higher the R-Value, the more the mattress insulates you from the cold ground. - R-value from 0 to 1.9: mattress designed for use in warm season (summer) only - from 2 to 3: mattress design for use in 2 or 3 seasons (spring/summer/autumn) - from 3 to 4: 4 season mattress, winter use possible - higher than 4.5: winter use and extreme conditions
Sleep comfort of mattresses, also called “postural comfort”, is measured by our Research and Development centre. All our mattresses are subjected to mechanical tests to check the performance and resistance of the mattress in order to guarantee you the best sleep and the best recovery. We also carry out numerous field tests in real-life conditions. Postural comfort is an extremely personal thing. You can adjust the pressure of your mattress.
Sleeping comfort, support
To prevent your sleeping bag from slipping on your mattress, the silicone patches must be placed in contact with the sleeping bag.
We have opted to change the colour of this product (previous model was blue) to take a step closer to conserving our natural playground. This mattress is now grey as we use a process that dyes one thread in two of the component, significantly reducing our water consumption and impact. Textile dyeing requires a lot of water but also produces waste water from the dye baths.
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.
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.
