An examination and treatment chair is operable to move between a generally upright patient entry/exit position and a reclined patient examination and treatment position. The chair includes a seat section and a beck section that moves between a generally upright position and a reclined position. Arm rests are rigidly connected to the back section and move with the back section. The arm rests are automatically positioned to allow a patient unobstructed entry into or exit from the chair.

An instrument delivery head for supporting hand-held instruments used in dental and other medical procedures. The instrument delivery head includes base and a lid connected to the base for movement between open and closed positions.
