Abstract
A dental patient chair has a seat, backrest and headrest which are adjustable in both the horizontal and vertical directions relative to a base part to establish a given chair position for treatment. The patient chair includes a controllable positioning arrangement which enables positioning a reference point or 'mouth point' in a particular position in both the vertical and horizontal directions and enables varying this point in view of changes either in the size of the patient, the size of the attending person, or a change between a sitting and standing position for the attending person.
