I was at the beginning more than skeptical - so much money on a little rubber mattress, and then to those mattresses also always mad lose air and one is the morning on earth.
We are more than satisfied! Inflation is very fast and the air stays overnight where they should remain. We tested the mattress straight 1 week how much air they lose in time. Of course, one decreases after a week a bit, but that is absolutely not an issue and not a malfunction.
Two nights without nachzu "ventilate" is not a problem.
The pump makes a bit of noise during venting, but is bearable, if you are not making it in the rented apartment at night by one.
The mattress offers enough space for 2 adult Menchen.
The rubber smell was completely gone after two days. Now she smells no longer at.
Was a good investment if there is no place for a permanent guest bed !!!
