How does a self-inflating mattress work?
A self-inflating mattress consists of a waterproof envelope glued to an open-cell foam in which air circulates. When you unfold your mattress, it takes on its original shape and thickness (8 cm for the AG Ultim Comfort), and fills with air as it unfolds. However, you'll need to finish inflating it by mouth, which also allows you to adjust the pressure to your comfort level.
Self-inflation is more or less perceptible, depending on the thickness of the mattress.
How do I inflate the ULTIM COMFORT VAN MATTRESS self-inflating mattress?
We recommend that you unroll your mattress as soon as you arrive at camp. Leave the valve open to facilitate pre-inflation. A self-inflating mattress inflates itself to around 80%. The rest of the inflation should be done by mouth, to adjust the pressure to your 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 insulation level of your mattress: ASTM F3340-18 standard.
This standard measures the mattress's ability to retain or reflect heat back to you to prevent heat loss and therefore provide thermal comfort.
Thermal insulation thanks to the foam.
R-Value ASTM F3340-18 standard self-inflating mattress AG ULTIM COMFORT: 8.6 (measured by an external laboratory)
Can the ULTIM COMFORT VAN MATTRESS be used in all seasons, even in extreme conditions?
The R-value expresses the performance and thermal resistance of the mattress. The higher the R-Value, the more your mattress insulates you from the cold coming from the ground.
- R-value from 0 to 1.9: mattress designed for use in the warm season (summer) only
- from 2 to 3: mattress designed for use over 2 or 3 seasons (spring-summer-fall)
- from 3 to 4: so-called 4-season mattress, winter use possible
- over 4.5: winter use and extreme conditions
How to twin the ULTIM COMFORT VAN MATTRESS?
