Nothing to complain about, it plays its role well...both in terms of comfort and lightness.
From the first use, the mattress does not remain inflated. After 3-4 hours, the mattress is so deflated that you are on the ground, therefore totally uncomfortable and no more insulation. Forced to get up and re-inflate it twice at night during the 2 weeks of use. Too bad because probably a defect. I bought 2 copies, the 1st (in L) works very well, the 2nd (in XL) not at all.
Worth recommending
Very thin mattress
I've owned this mat since 2019 and I would recommend it in itself, but the mat is not compact at all and the sleep is like sleeping on the floor, so unfortunately not such a good rating.
comfortable
Compact when folded. Perfect for a rocky beach in Croatia.
Self-inflating system difficult to understand but apart from that very practical mattress
meets expectations
I slept well on it for two nights. But on the third night it was very windy, we had to leave the tent unzipped to prevent it from being destroyed. And the lovely mat suddenly took off and flew towards the Adriatic Sea.
Very good product
Alright
I already had several mats, different companies, and I was not satisfied with them. I bought the Forclaz mat without enthusiasm, but it turned out better than I thought. After a month of intensive use, I can say that it is money well spent. Everything is as it should be, the only remark is too slippery material on the side without hooks. But that's a minor thing overall. The valves hold well, the mat insulates well, gives advice. I will buy another one just like it.
Very good mattress.

Additional Product Information
Composition
Foam: 100.0% Polyurethane ; Floor mat: 50.0% Thermoplastic Polyurethane, 50.0% Polyester ; Main fabric: 50.0% Thermoplastic Polyurethane, 50.0% Polyester ; Carry bag: 100.0% Polyester
The principle of a self-inflating mattress
A self-inflating mattress consists of an airtight envelope glued to an open cell foam in which the air circulates. When you unfold your mattress, it will return to its original shape and thickness (2.5 cm for the MT100 mattress) and fill with air. However, it requires some mouth inflation so you can adjust it to the pressure level suitable for you. Self-inflation is more or less noticeable depending on the thickness of the mattress.
Easy inflation/deflation
When using your mattress for the first time, unroll it, open the valve for 24 hours on a flat surface, then inflate it and leave it for 24 hours, valve closed, under pressure. Then you can store it away again. While trekking, take out and unroll your mattress as soon as you set up camp, valve open to facilitate pre-inflation. A self-inflating mattress inflates to about 60 to 70% on its own. You will need to blow up the rest yourself, so you can adjust the pressure to your desired comfort level.
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)
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 repair a leaky 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: 8557113).For more information, copy the following link into your browser:https://www.forclaz.co.uk

In order to improve the durability and reliability of your product, store it laid out flat with the valve open in a dry place away from extreme temperatures.
