A chair that converts from a conventional seat and back rest type of chair to a seat and knee rest type of chair utilizes a seat that is pivotally connected to a base support that, when pivoted, is rotated from a generally horizontal plane when used as a conventional chair, to a predetermined angle of tilt. The back rest is also pivotally connected to the base support by a bracket arm that permits the back-knee rest to be moved from a position above the plane of the seat, to support the back of a person sitting on the horizontally positioned seat, to a position below the plane of the seat and at a predetermined angle of tilt to support the knees of a person sitting on the tilted seat.
