Abstract
An air bed has side-by-side air mattresses confined within the perimeter of a rectangular border. The border has a plurality of border walls each located within a fabric case. The case accommodates upper and lower foam members of different density. The upper foam member has a density so as to be sufficiently resilient reducing discomfort to a resting person. The lower foam member has a density so as to be sufficiently rigid to retain the air mattresses within the perimeter of the border. Velcro fasteners are used to normally join the border walls. The bed is equipped with a cover having a releasable fastener so that the cover may be readily removed from the air mattresses and border.
