I used to sleep on the Coleman's air mattresses, then went to the aerobed, they typically lasted about 18 months. When I went with the MH, I found Bear Beds. Love it. I had tried the sleep number bed, at over 2 thousand dollars, it was the most uncomfortable bed I've ever tried, went back to my coleman's or aerobed. Then someone suggested the Bear beds, thought it would be like the sleep numbers, uncomfortable, Nope, best bed I've ever tried. I went with the queen short (for RV's) with one air chamber, since there's only me, why have two. Have been using it for about 2 years. It's the best.
