Abstract: A high-low base including a lower frame member supported upon a floor, an upper frame member, and an elevation assembly for variably elevating the upper frame member in height above the lower frame member, fits completely under, and within the pedestal base, of a conventional contour bed. A motorized drive mechanism variably controllably elevates the upper frame member in height above the lower frame member, and the entire contour bed including its pedestal base in height above the floor, in order to facilitate transfer of a bed user to and from a wheelchair, or the provision of care to the user supine within the bed. An upper surface of the contour bed is adjustable to contour a mattress that rests upon this upper surface mechanically and electrically independently of the adjustment of the height of the bed.
