But well ... you can indeed buy an air mattress - this one must also inflate or directly buy ne 10cm thick mattress. This, however, can not be transported so nice :)
I find the mats good and I would, if necessary even buy a third. The only flaw I could find out so far is the transport bag. When a seam is already torn when I had packed the mat. But the Velcro straps hold the roll together so yet.
All in all satisfied and we have not regretted the purchase.
