Given that a quality air bed is purchased, almost all of the things which were once issues should no longer be areas of concern. Air beds alleviate the problem of camping beds because they can be simply packed in a smaller bag, and then blow an inflatable bed up when you get there.
Any air mattress is susceptible to the same types of problems as any other air mattress. Many manufacturers have now inserted a layer of convoluted high-density foam, air flow layer, non memory, between the base and top layers, to help dissipate body heat. Some air mattress are very comfortable and can be used as a replacement for a regular bed.
Twin beds are commonly used for the bedrooms of the children and for multi-user guest rooms. But those who have become the biggest advocates of the foam mattress report that its biggest benefit, by far, is the relief it provides for their aching bones and joints. If you can t remember the last time you experienced a full nights sleep on your current mattress, it's been too long.
Serta, Sealy and Jamison make fine mattresses, both conventional and memory foam, but to my mind, the original memory foam mattress is still the best; the Tempur-Pedic. And if you're comfortable on your current bed, then don't fix what's not broken, but for those pregnant women who are experiencing a great many sleepless nights and are avid side or belly-sleepers, a maternity air bed is worth considering.
