How to inflate your mattress

To prevent moisture from being blown into the mattress, we recommend that you use the pump bag in the pouch.
To do this, unroll the entire pump bag/pouch. Connect the valve of the pump bag to the “IN” valve of your mattress. Blow to about 10-20cm from the inlet of the pump bag, to inflate the main volume as much as possible. Roll the bag on itself to the valve to push the air out of the main bag into your mattress.

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.

It should be noted that R-Values add up; this means that you can use 2 mattresses and add up their R-Value.

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.Other patches on the underside reduce the slippage of the mattress on the floor of your tent.

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).
