Light and practical. You don't have to inflate it too much to make it comfortable.

I bought this mattress which was recommended to me by a seller but during the first use the bag was pierced. My daughter finds herself sleeping on the ground while camping.

Nickel for the current bivouac. Not too heavy.

better than nothing

Bought in Denmark during a trip to the North Cape to replace my old one (10 years old) which was very comfortable but which no longer held up the air. It has anti-slip patches but it still slips, the side cushions deflate poorly, poor comfort if not zero. Tested for ten days camping and trekking.

I have done several treks…

I have done several treks with it and it is comfortable and easy to transport! Just a little hard to fold!

Comfortable mattress and good insulating power


Mattress for trekking but remains thin and over several days the pain sets in, particularly in the hips. Otherwise easy to inflate, store, very light.

Good mattress

Good compact and light mattress. It's a shame that it's so expensive, but it works perfectly well with a groundsheet for insulation. The anti-slips work well with my sleeping bag.

Ok the first one is pierced… I hope this one will be more resistant

How to choose the size of your mt500 mattress

This model is available in L and XL version. The difference between the 2 sizes on the length (180 cm for the L; 195 Cm for the XL) and width (52 cm for size L; 60 cm for the XL).To choose the mattress that best suits you, you must consider your stature, but not just that. Your preference and/or your preference for space around your shoulders should also be considered. So, even if you are 1.75 cm, you will prefer the XL!

Tips for sleeping well on your mattress

Once you are lying down, remember to adjust the inflation pressure of the mattress by slightly pressing the IN valve (open cap). A mattress that is too hard is often synonymous with discomfort.Silicone patches on the top of the mattress are designed to reduce the sliding of your sleeping bag on the mattress.

How to easily fold the mt500 air mattress?

The easiest way to fold your mattress without damaging it is to fold it in four lengthwise, then roll it up.

How to repair a leak on your mt500 air mattress?

An inflatable mattress is not puncture-proof but it can be repaired!When using it, take every care when installing and handling it. In the event of a problem, we recommend using self-adhesive repair patches (ref: 8584596).For more information, copy the following link into your browser:

What is the r-value?

The R-Value is a measure of the thermal insulation. It measures the ability of a mattress to retain or prevent heat from escaping from a warm body (human body) to a cold floor.The higher the R-Value, the better the insulation of the mattress.Please note that the R-Values can be added; this means that you can use two mattresses and add their R-Values.All our mattresses are tested to standard ASTM F3340-18.

What r-value for what use?

R-value from 0 to 1.9: Hot season (summer) onlyR-value from 2 to 3: Use over 3 seasons (spring/summer/autumn)R-Value from 3 to 6: Use over 4 seasonsR-Value > 6: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)

Volume and folded size

Folded dimensions Ø 3.9 Inch (10 cm) x 8.7 Inch (22 cm).Volume: 1.7 liters.Weights, volumes & dimensions may vary slightly due to production tolerances.
