camping self-inflating comfort mattress

It is really important to inflate your mattress to a good pressure.
Do not over-inflate in order to reduce wear and tear and avoid damaging your back, but inflate the mattress enough so that it is comfortable and allows you to sleep properly. When sitting on the mattress, your bottom should be touching the ground.

A self-inflating mattress inflates itself to approximately 80% full. So, leave it for about 20 minutes with the valve open and then adjust the pressure using mouth-inflation.

This mattress uses a double valve system: the IN valve draws in air but can also expel it when the black non-return valve is pressed if you want to adjust the pressure while lying on the mattress.

Open the valve OUT during deflation to expel the air. To speed up the process, stand at the opposite end to the cap and press down on the mattress so the air comes out faster.

Once the mattress is deflated, you can fold it in half across the width. Then zip the side of the mattress, roll it up lengthwise starting at the opposite end from the valve and put it in its bag. Remember to close the valve.

As mentioned previously, the pressure of the mattress is the key to a good night's sleep. When seated, you should be able to feel the ground. When you are lying down, the air will spread evenly under your whole body.

There is no preferred way to sleep: you can sleep with your head at the valve end or at the other end; do as you see fit! We advise you to put your head close to the valves so that you can adjust the pressure of the mattress at any time.

For maximum comfort, get a sleeping bag with the correct temperature rating, as well as a pillow.

The R-value standard (ASTM F3340-18) measures the thermal resistance of the mattress, i.e. the level of insulation it provides against the cold coming from the ground.
There are various levels:

- 0 to 1.9: summer use only
- 2 to 3: can be used from spring to autumn
- 3 to 4: can be used all year round
- greater than 4.5: winter use and adapted to extreme conditions

This mattress has an R-Value of 5.2.

When you sleep, the sound of the friction between the mattress and the ground can be annoying.
Do not over-inflate in order to minimise this problem.

You can also put a blanket or a sheet under the mattress.

If you want to improve the thermal insulation of your mattress and get better protection from the cold and moisture of the ground, you can put a foam mattress or a survival blanket under your mattress, or a groundsheet under your tent.
