Delivery was fast and good, the pillows are actually useless, but that was in sight. Unfortunately, the beginning of our trip was not easy with the bed. The first night lost the bed after 2 hours slow air and I had the feeling of being swallowed up by the mattress. So get up at 1:30 clock and re-inflation. 3.00 clock - my partner turns. He had back pain since now again dodged air and the whole resembled sleeping in a hammock. Then I was nearly seasick because the bed developed in not fully inflated state almost of its own. 3.30 clock - I throw myself on the side and my partner nearly falls out of bed. Additional pumping and again to check the valve. 5.00 clock I get up, because I fall again into the mattress. My partner, thus sleeping on the ground. 7.00 clock - we build the valve apart, lubricate Körpfercreme on both sides of the membrane, and lo and behold - the bed has kept tight for 6 days a re-inflation was not necessary.
