Very good camping mattress. Inflates evenly and is as firm as needed. Its advantage is that it is not like other mattresses that make you feel like you are floating when you move. Its disadvantages are the price and the space it takes up even when deflated + the time it takes to inflate/deflate.

The durability of these specific valves remains to be seen as I have read several comments stating that they lose air over time, so it is good to keep that in mind. However, it is an awesome substrate. Quality-wise and practically.

Amazing mattress. It inflates quickly on its own and deflating it is quite easy if you are two people. The specific thickness of 7.5cm is satisfactory and makes for a very comfortable sleep. 10cm might be excessive. Its size is also very comfortable for two people of average build. I consider it to be superior to conventional air mattresses, which tend to lose air or get punctured after a season (besides the hassle of inflating them). Another positive is that your partner doesn't move when you toss and turn. It has a memory foam feel. I highly recommend it.

Very good self-inflating mattress for a comfortable sleep. I got it on sale for a price well below 100€. The only negative is that it has one valve and when it's time to pack it up, it takes more time compared to those with two valves.
