Product Customer Reviews

Excellent, I recommend it
It's light, perfect for the price
A little fragile
Very good for occasional use.
Better than a simple foam mattress but not very easy to transport, especially to protect it from the rain (you have to "make" a cover).
All-over great product..but it should be a little bit more wide for fat people
In troubleshooting, not great over several days.
Satisfied
The foldable one is so much easier to use than the round one. I would like to see its durability but good product for my bivouacs
I am not satisfied with this product, I used it only one night and I had back pain, not at all comfortable and for transport it is not great, I am really disappointed
It is very comfortable and you sleep well but it takes up space when transporting it.....
Good value for money. Preferable to self-inflating ones which end up punctured (except those from the brand well known for its lifetime guarantee, and which I will not mention here)
I used it is honestly it's great
Slept wonderfully.
This is a decent and robust mat, with a good R value.. Suitable for using on it own in summer, or putting under your inflatable mat in winter as a boost to your sleep system. I'm very happy with my purchase

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: 2 or 3-season (spring-summer-autumn)R-value from 3 to 4: 4-seasonR-value of 4.5 and higher: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)
Comfortable postural support
For a foam mattress, this mattress offers a greater level of comfort thanks to its design and the depth given to the foam by the mould. This specific design allows for 2 cm mattress thickness, giving home comfort and real postural support.
