How does a self-inflating mattress work?
A self-inflating mattress includes a waterproof casing that is bound to open-cell foam in which air can circulate. When you unfold your mattress, it will take its original shape and thickness (8 cm for the AG Ultim Comfort) 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.
How to inflate the ULTIM COMFORT VAN MATTRESS self-inflatable mattress
We advise you to get out and unroll your mattress as soon as you set up camp. Leave the valve open so that the mattress pre-inflates. A self-inflating mattress inflates itself to about 80%. You will need to blow up the rest yourself, so you can adjust the pressure to your desired comfort level.
Can the ULTIM COMFORT VAN MATTRESS be used in all seasons, even in extreme conditions?
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.
R-Value standard ASTM F3340-18 self-inflating mattress GA ULTIM COMFORT: 8.6 (measured by an independent laboratory)
Can the ULTIM COMFORT VAN MATTRESS be used in all seasons, even in extreme conditions? (continued)
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
