Here is an excerpt from experts who have tested all the air beds on the market and they offer buying guides, what to stay away from and more importantly for you.."why it deflates". Basically they say that these "over-engineered" beds with remote controls and numerous layers of cushions/ foam etc.etc. have so many "port" valves, which if not tightened correctly or which are not made with TOP quality materials...will tend to "leak". Anyway...read the below and then click the link for the complete article. "what's even worse, air beds with multiple air chambers also have multiple ports for pumps and valves, which means more air leakage problems if the valves and fittings are not of extremely high quality, or if they are not positioned or installed properly so that they don't eventually become loose or disconnected. Also, poor quality foam layers, which, while looking "poofy" and adding altitude, in fact may be comfortable for the first few months of use, but quickly deteriorate and compress. "
