So uncomfortable

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.

Give it a pass

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.


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.

very comfortable!

great to use on sand, grass, and pebbled surfaces

Perfect Buddy

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.

Solid bed

Much better than other brands which only need a few breath to fully inflate the inflatable bed. Minimum time required to prepare for resting.

Супер е

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.

Самонадуваема постелка

Удобно е за спане. Възглавницата идеално я допълва.

проблем с клапата

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. 

Спортни поздрави,

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 (2.5 cm for the trek 500 mattress) and fill with air accordingly. 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.

Thermal protection and heat

Since the beginning of 2020, a new standard has been validated to assess the level of insulation of your mattress: standard ASTM F3340-18.This standard measures the capacity of the mattress to retain or return body heat in order to avoid its loss and therefore provide you with thermal comfort.Thermal insulation thanks to the foam.R-Value standard ASTM F3340-18 mattress Trek 500 self-inflating: 2.7 (measured by an independent laboratory)

Thermal properties and warmth (2)

The R-value expresses the thermal performance and resistance of the mattress. The higher the R-Value, the more the mattress insulates you from the cold ground.- R-value from 0 to 1.9: mattress designed for use in warm season (summer) only- from 2 to 3: mattress design for use in 2 or 3 seasons (spring/summer/autumn)- from 3 to 4: 4 season mattress, winter use possible- higher than 4.5: winter use and extreme conditions

Product test

The sleep comfort, also called "postural comfort", of our mattresses is defined by our R&D centre. All our mattresses are subjected to mechanical tests to assess their performance and durability and ensure you enjoy a good night's sleep and an excellent recovery. We also carry out numerous field tests in real-life conditions.Postural comfort is an extremely personal thing. You can adjust the pressure of your mattress.

Sleeping comport, support

To prevent your sleeping bag from slipping on your mattress, the silicone patches must be placed in contact with the sleeping bag.


We have opted to change the colour of this product (previous model was blue) to take a step closer to conserving our natural playground. This mattress is now grey as we use a "bi-ton" process that dyes one thread in two of the component, significantly reducing our water consumption and impact. Textile dyeing requires a lot of water but also produces waste water from the dye baths.
