The principle of a self-inflating mattress
We advise you to get out and unroll your mattress as soon as you set up camp. Leave the valve open to make pre-inflation easier. 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.
What are the dimensions of the mattress?
The Ultim Comfort mattress is 200 cm long, 70 cm wide and 8 cm thick.
The mattress weighs 2.9 kg and fits into a cylindrical cover measuring 72 x 50 x 11 cm.
How should I use my mattress the first couple of times?
For the first two uses, inflate by mouth to activate self-inflation
Thermal properties and warmth: winter use and 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)
Thermal properties and warmth (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
