I am writing this review that not yet another buy this bed. The bed is shaky. The margin is too soft even if it has been aufgepumt. If one does not remain exactly in the middle (who can even during the sleep) the rolls down. My opinion is, the bed is too high for this latitude. At least meets the to this bed. It tilts if you want to get up. Even if you reinpumpt less air, one is uncomfortable. Maybe that's better for two people if it is wider. After three times inflate the valve was no longer tight. It departed relatively quickly the air. When I went to complain, recommended me the seller, me to contact the manufacturer. That's a No Yes. Because where I buy because I complain also. I turned directly to Amazon. Super Service !!! You have me helped to my right. Again, many thanks !!!
