I have often heard from people that sleeping on airbeds is not good for health, reasoning that it is filled with air and molds to the shape of our body, so cannot provide enough support for the back.
My roommate has been sleeping on an airbed for last few months, but doesn't seem to have any kind of problem.
Also, I wasn't able to find any credible proof to this claim on the internet. So was wondering if it is really true!
