The one quibble most people have with air mattresses is that they can slowly lose air while you're sleeping on them. Serta solves this problem with the Review of Serta Raised Air Mattress with Never Flat Pump. This air bed's dual pump system senses when the mattress is deflating and activates to maintain the air pressure to your chosen firmness level; there are three to choose from. The twin bed measures 74 by 39 by 18 inches, and a 2-year warranty and good customer support will ensure long-term satisfaction.
I also appreciate the air bed pump that comes with this Insta-Bed. To inflate your air bed, all you have to do is to turn it on and you can do something else to prepare for the night. The pump has an auto shut off feature which turns the unit off when the bed is already full of air.
