Air beds designed for both indoor and outdoor use are in the same price range as standard-height air beds, but offer more versatility. The Coleman 4-in-1 Quickbed (*Est. $50 without pump) can be inflated using battery power or a car adapter (not included), plus it can convert from two twins to a king-size air bed. Meanwhile, the Wenzel Insta-Bed Queen Raised Sure-Grip Bottom with Built-In Pump (*Est. $120) is about the same height as a regular bed, so it's easy to get in and out of.
