Camping with a mere 1 cm foam sleeping mat wasn't comfortable, so I'm looking for a non-self-inflating air mattress. I plan to go camping with a tent from spring to fall, so no need for high isolation or resistance to sharp objects.

Amazons sells pic related for 40€, does anyone have experience with it? Is it worth if I only go camping 2-3 times a year or am I better of with a more expensive one with a pump sack?
