Abstract
An article of seating furniture is provided with a lift mechanism. The article can be a chair with a base and a seat that is pivotally connected to the base. A back is coupled to the seat and may be either fixed to the seat or rotatably coupled to the seat. An actuator is mounted to the base extending towards the rear of the chair. The actuator is pivotally coupled to the base on one end and is pivotally coupled to the seat on the other end. The actuator moves the seat between a generally horizontal position and a raised position. With the back rotatably mounted to the seat, a linkage bar can be added that extends from base front to a bracket that mounts the back to the seat. The linkage bar reclines the back as the seat is raised from horizontal position to the raised position.
