The elevator chair has a seat assembly mounted on a support frame which includes an occupant supporting seat having a rear seat section, a seat back connected to and extending upwardly from the rear seat section and a front seat section which extends substantially across the extent of the rear seat section and which is pivoted to the rear seat section. A seat drive unit drives the seat assembly from a first position where the front and rear seat sections extend in the same first plane to a second position where the rear seat section remains in a second plane parallel to said first plane while the front seat section angles downwardly and outwardly. Subsequently the seat drive unit drives the seat assembly to a third position where the rear seat section tilts forwardly toward the front seat section.
