ABSTRACT:
An air bed includes first and second air-tight enclosures disposed side by side in a first plane. Each of the first and second air-tight enclosures is independently inflatable and has substantially the same length and width, the first and second air-tight enclosures together having a first cross-sectional area in the first plane. An inflatable foundation is disposed below the first and second air-tight enclosures in a second plane substantially parallel to the first plane. The inflatable foundation has a cross-sectional area in the second plane at least as great as the first cross-sectional area. The inflatable foundation is independently inflatable with respect to the first and second air-tight enclosures. The first and second air-tight enclosures and the inflatable foundation are secured together by a circumferential belt, with the first and second air-tight enclosures fixed in place with respect to the inflatable foundation.
