As posted, glorified air bed, you can get at any sporting goods camping section for far less money.

If you get a conventional Matt and Box - ask for a king matt that can be bent in half, like a sandwitch . .  most mfgs make a matt that hinges in the support wire around the matt . .  then you should be able to get a matt in any room/floor that the box spring fits (all king size bedding have 2 box springs).

The return rate for select comfort beds was higher then conventional bedding but not as high of return rate as the all foam bedding (Temperpidic) . . . . .
