Alternative use!

I bought this product for my daughter's school transport for when she has a seizure this can be quickly unrolled (I velcroed on a pillow at one end) to ensure she has a safe, clean and dry surface for first aid to be administered and her head is kept safe at all times.

Son had this for going to DOWNLOAD FESTIVAL, he's 20. Helped to soften the ground, it never came back home though.

QUECHUA Foam Mattress M200

We bought this for my sons camping weekend. It was great value for money and the straps meant he could roll it up and carry it easily. It's thicker than the cheaper versions so kept him warmer and he had a decent nights sleep.

Сви се с 6 сантиметра

Купих два броя преди повече от година. Ползвани са 3 нощи. Сега реших да ги измеря и се оказа че са се свили и в двете посоки. Вече са 58х174см. Не са прани или дори почиствани. Съхранявам ги под леглото си. Много странно. Ако пазех касовата бележка бих ги върнал или сменил. Може би некачествен материал е бил тази партида.


Наистина добро

За цената е с добро качество

Аз бих препоръчала да си взимате по възможност малко по-дебело шалте за по-ниско температури. За лятото е перфектно.

Купихме 50 броя за похода "По стъпките на Ботевата чета" май месец 2016 г. Децата бяха много доволни, оказа се изключително сполучливо. Тази година ще ги използваме отново.

Additional Product Information



  • 100% Polyethylene low density

Volume and folded dimensions

Rolled dimensions Ø 5.9" x 23.6". Volume 10.6 liters. Density of the foam 66.1 lbs/m3.

Thermal insulation and warmth

Sleep on the aluminized side, facing the sleeping bag with the foam side on the ground to minimize losses of body heat. R-Value 1.3 (measured by EMPA, an independent laboratory). The R-Value is a measure of the thermal performance and insulation. The higher the R-Value, the more your mattress will insulate you from the ground. An R-Value of 5.9 is equivalent to a minimum temperature rating of about -11°F. 0.7 is equivalent to a temperature rating of +52°F. The R-Value is not a standard.

Product test

The bedding comfort or "postural comfort" of the mattresses is defined by our research and development center. All our mattresses are subjected to mechanical tests on their performance and durability to guarantee the best possible quality of sleep and recovery. We also conduct many tests in the field in real-life conditions.

A score for comparing products' environmental impact

The environmental impact of the products is calculated with different indicators based on the lifecycle of the product. An ABCDE score is provided to help you easily identify the most environmentally friendly products. Use the score to compare the same type of product (T-shirts, pants, backpacks). Decathlon is a voluntary supporter of this environmentally-friendly labeling approach. Explanatory video:
