When it is inflated, you can sleep comfortably and relaxed ...

... If not the exact opposite. That's certainly clear to anyone who has forgotten times in Camping his air pump for the mattress and the manual way is either not interesting due to too much fatigue, or alcohol level. This mattress is Abert very important that they fully inflated ready for sleep is, or you can not find peace.

After unpacking it stinks strongly of rubber and cheap plastic. Assembly is easy, free from the closure plug and turn on the opening after inflated, or has been blowing.
From my side, I was about to a simple air pump for Planschebecken should order with, because from a certain amount of air in the mattress comes out more air than you can blow into it, about when the mattress is half full.
For carefree sleeping experience is not enough, but you get the rum night.
The next day you should prepare himself for the second time because the air escapes, somewhere that thing is leaking and it has half the air again into it.
For me this is definitely absolutely unacceptable, an air mattress, which does not hold tight. Considering the convenience of the coating and the halfway ergonomic adaptability will not get here three star, well deserved, but two are certainly not enough.
