My Advice:
I have therefore the mattress I wanted to replace it with the double air mattress priority in luggage. A Happy People PVC Airbed. Although is very narrow and therefore not suitable for drifting deep relaxed, but it is space-saving. In addition, they can be misused as "Float" and (also for couples) lay only with the upper body on it. Because it actually is too small, you have almost "with the mattress fight" in order to use them can. I love the more fun than just draufzulegen and herumzudümpeln.
But of course each his own.
Conclusion:
Good workmanship and durability, enough space for one person, however, problematic transport, when it comes to precious storage space. Since it is more of a granny, so a two Lieger there are 4 stars.
