How was this mattress designed for more comfort?
The 8.5 cm thick mattress has been designed to provide greater comfort when bivouacking. Also, a special coating on both sides of the mattress prevents your sleeping bag from slipping on the mattress and the mattress from slipping on the groundsheet.
How did we tackle this mattress's durability?
To limit the spread of a tear, the fabric used is made of 40 denier polyamide with thicker 45 denier thread. We use the same fabric on both sides of this mattress for greater resistance.
How to easily inflate your MT900 mattress
To inflate your mattress without putting moisture inside, we recommend using the pump in the cover. To do this, unroll the pump bag along its entire length then connect the valve to the "IN" of the mattress. Blow to about 10-20 cm from the inlet of the pump bag to inflate the main section as much as possible. Roll the bag on itself up to the valve to push the air out of the main bag into your mattress
How to sleep on your inflatable mattress
Once you are lying down, remember to adjust the inflation pressure of the mattress by pressing lightly on the IN valve (open cap). A very hard mattress can create discomfort.
How to choose the right size of air mattress
Size L measures 183 x 54 cm, the XL 195 x 63 cm. To choose, use your height, but also your stature and preference about space for your shoulders. Even if you are 1.75 m tall, you can choose the XL for greater comfort.
What is R-value?
The R-Value measures the thermal resistance of a mattress to prevent body heat from escaping. The higher the R-value, the better the insulation. R-Values can be added together, so you can combine two mattresses and add their R-Values for more insulation.
What R-Value depending on its use?
R-value from 0 to 1.9: Hot season (summer) R-value from 2 to 3: Use over 3 seasons (spring/summer/autumn) R-value from 3 to 6: Use over 4 seasons R-value > 6: suitable for use all year round, including in freezing conditions.
