Abstract
A bed has a foundation for supporting an air mattress. The foundation has a plurality of pivotally connected transverse plates that are moved to bend the mattress to a desired contour and shape. Open top recesses in the foundation located below the plates accommodate bags have flexible walls. The bags are separately expandable and contractible to move the plates to selected elevated positions. The recesses hold the bags in lifting positions relative to the plates when the bags are inflated. The bags fit into the recesses when deflated to allow the plates to move to a horizontal position. The bed is equipped with a vibrator that is operable to vibrate the air mattress.
