Product Customer Reviews

Comfortable had a good sleep for 3 nights, easy to pack, no complaints from my family members too
I had the 5 worst sleeps of my life on this thing. It barely has any padding to it, so even fully inflated it's super thin and marginally better than sleeping on the ground.
Bought 2 of them last year and used 3 times. Keeps deflating through the night so you end up sleeping on the floor. First times I thought I didnt close the lid properly, bit that’s not the issue. Very very disappointed having spent $120 on these. May I add I always rolled them back in their bags after use.
I like this mat so much that I am going to buy another one for my son. It's warm and easy to roll up.One very happy customer.
Light weight, very good quality
The product is good i.e. does the job well. However, loses one star because it's hard to deflate and roll back into the bag.
great to use on sand, grass, and pebbled surfaces
This item is a must. It is so light and it doesnt need much effort to put air on it. You can even use it with or without air inside.
it's a wonderful item, especially with the self-inflating mechanism - easy to set up and to keep.

Light and warm. Good support for my back. Simple product to carry.
Thank you for your feedback.
Glad to know that this self-inflating mattress serve you well.
Yes, this mattress is light, weighing only 820g. It is ideal in mild temperature (10 to 20 degrees celcius). Thermal insulation due to foam.
Hope to hear from you again :)

Much better than other brands which only need a few breath to fully inflate the inflatable bed. Minimum time required to prepare for resting.
Thank you for your review.
Glad to know that you enjoyed our product.

Дюшекът си е идеален. Ползван е в гора на повърхност от тръни и листа, както и върху твърда повърхност със суха трева - достатъчно добра работа върши. Надува се бързо, лесно се събира и учудващо - не е супер трудно да си го прибереш в торбичката за него.
Удобно е за спане. Възглавницата идеално я допълва.
Използвам шалтето близо година и бях много доволен. Компактно е, доста удобно, но миналата седмица ми се развали клапата. Надявам се да ми го заменят, така че съветвам ако си купите такова да си пазите касовата бележка.
Благодарим Ви за обратната връзка! Ако продуктът има дефект, може да заповядате с касовия бон в предпочитан от Вас обект на Декатлон, за да може екипът ни да прегледа продукта и да Ви съдейства за рекламацията.

Koupili jsme 2 stejný se stanem i spacáky. Je kvalitně provedená i na tvrdším a kamenitém podkladu tlumí velmi slušně. Možnost dofouknout podle sebe. Má dvě části s protiskluzem (maličko bych přidal rozsahem) a sjížděl jsem trochu jen jednou v mírném svahu, což příště vyřeším spaním na větší rovině =D Jinak jsem s ní neměl nikdy problém. Ikdyž 700 varianta vyjde lépe váhou i rozměrem ve sbaleném svahu, tak za mě tahle splnila nad očekávání a zdá se mi i v porovnání s větší výdrží a odolností než-li ta 700. Měřím 173 a ta 180 varianta je délkou na pohodu, váhou se pohybuju 70-80 a nebyl problém. Bral jsem jí i jen na obyčejný válení se kdekoliv abych se neotlačil o kameny a stále drží v pohodě =D Dá se dobře vyprat či omýt povrch. Po druhém či třetím použití přijdete na jednoduchý způsob rychlého vyfouknutí a sbalení do co nejmenšího stavu (přeložit a rulovat postupným zaklekáváním), možná jen občas se nechce zalehne vyfukovací otvor (potřeba do něj strčit prst nebo jakkoliv jinak ho "prošťouchnout" =D). Mám jí 2 roky a spal jsem na ní třeba 40x. Dle potřeby ufouknu po hmatu. A párkrát mi ráno přišlo, že mírně ušla, ale díru jsem nenašel a spíš jsem jen špatně zatlačil špunt k nafouknutí nebo vyfouknutí =) Jasně, dá se koupit kvalitnější a lehčí a určitě i pohodlnější, ale za mě dobrá volba v porovnání cena/výkon/kvalita .´-)

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 the mattress, it will return to its original shape and thickness (1" for the trek 500 mattress) and fill with air accordingly. However, it requires mouth-inflation to attain the required pressure that suits you. Self-inflation is more or less noticeable depending on the thickness of the mattress.
Easy to set up and put away
When using your mattress for the first time, unroll it, leave the valve open for 24 hours on a flat surface, then inflate it and leave it pressurized for 24 hours with the valve closed. You can put it away again. When bivouacking, take out and unroll your mattress as soon as you set up camp, valve open to facilitate pre-inflation. A self-inflating mattress inflates itself to approximately 60 to 70%. To complete the process, mouth inflation is required to adjust the pressure to suit you.
Thermal properties and warmth
Thermal insulation thanks to the foam. The R-Value expresses the performance and thermal insulation of the mattress. The higher the R-Value, the more the mattress insulates you from the cold ground. R-Value 2.3 (measured in an external EMPA laboratory) An R-Value of 5.9 is equivalent to a minimum temperature rating of about -11°F. 0.7 is equivalent to +52°F The R-Value is not a standard, and each manufacturer can use their own criteria. A standard process is currently being developed.
Product test
The sleeping comfort, also known as "postural comfort," of the mattresses is defined by our Research and Development Center. All our mattresses are subjected to mechanical tests to check the performance and resistance of the mattress in order to guarantee you the best sleep and the best recovery. We also carry out numerous field tests in real-life conditions. Postural comfort is a very personal element. You can adjust the pressure of your mattress.
Sleeping comfort, support
To keep the slippage between your mattress and your sleeping bag to a minimum, the silicone patches must be placed in contact with the sleeping bag.
