ABSTRACT:
A dental treatment chair including a seat, a backrest tiltably attached to the seat, and a drive means for tilting the backrest. The chair includes a unit table which stays horizontal and moves and up and down as the backrest tilts, and the table is further connected to the backrest by a longitudinal shaft and a support shaft so that it can freely rotate in a horizontal plane. By means of this structure, an operator can take a position convenient to access treatment tools and to take a position opposite to the unit table in response to each tilting phase of the backrest.
