How to choose the right size of MT 500 Inflatable Mattress
This mattress is available in an L and XL version. The difference between the 2 sizes is the length (180 cm/71” for size L; 195 cm/77” for size XL) and width (52 cm/21” for size L; 60 cm/24” for size XL). Consider your height to choose the mattress that best suits you. However, also consider how much space you like to have around your shoulders. So, even if you are 175 cm (5’7”), you may prefer the XL!
How to inflate your MT 500 Mattress
Use the pump bag in the cover to keep moisture out of the mattress. To do this, unroll the entire pump bag. Connect the valve of the pump bag to the “In” valve of your mattress. Blow to about 10–20 cm (4–8”) from the pump bag inlet to inflate the main bag as much as possible. Roll the bag up until you get to the valve to push the air out of the main bag and into your mattress.
A tip for sleeping well on the MT 500 Mattress
Once you are lying down, remember to adjust the inflation pressure of the mattress by lightly pressing the “in” valve (open cap). A mattress that is too hard is often uncomfortable. Silicone patches on the top of the mat are designed to stop your sleeping bag from sliding.
How to repair a leak on your MT 500 Inflatable Mattress
Inflatable mats are not puncture-proof, but they can be repaired if punctured. Take care when inflating and moving the mat. In the event of a problem, we recommend self-adhesive repair patches (ref. number: 8557113). For more information, visit our website.
What is R-value?
R-value measures thermal insulation. It indicates how much heat a material retains or allows to escape. The higher the R-value, the better the insulation. R-value can be increased: stack two mattresses to combine their R-values. All our mattresses are tested to ASTM F3340-18 standards.
What R-value do you need?
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.
Volume and folded size
Folded dimensions: 12 cm x 30 cm (5” x 12”). Volume: 3.4 L (0.8 gal)
