Abstract
A height adjustable bed on a floor provides a two stage continuous adjustment system and method of operation thereof. An upper frame is raised from a lowermost position to a maximum intermediate position with a first set of legs resting on the floor. The upper frame is further raised from the maximum intermediate position to an uppermost position with a second set of legs resting on the floor. The transition from the first set of legs to the second set of legs and vice-versa is smooth and continuous. The system is powered by a reversible electric motor. A much greater range of distance is achieved over previous height adjustable beds. The ratio of uppermost distance of the upper frame off the floor to the lowermost distance can be greater than 2.5. A third set of wheeled legs can be added for mobility when it is desired to move the bed.
