For now, I give it 4 stars due to the 17€ price including shipping compared to what it offers. It stays inflated for 7 consecutive days without losing almost any air.

19/5/24: Inflated for 4 months without losing any air. Excellent!!

I have had the product for a few months. It is mainly used for camping. The quality of its materials is very good. The air loss is minimal and can only be noticed after a few days. Overall, a reliable product at a reasonable price.

It is used as an auxiliary mattress in a country house. Really very convenient with the great advantage that it is cool for hot summer nights.
The air loss is minimal, it needs a little supplement every 3 days to maintain its firmness, alternatively I believe it comfortably lasts a week.
Loses one star because it is identical to its cheaper blue sibling https://www.skroutz.gr/s/17817781/Intex-Classic-Downy-64757-99x191cm.html?from=catspan
