A seat apparatus and method particularly well adapted for use in mobile platforms, and more particularly in a commercial aircraft. The seat apparatus includes a seat portion with linkage that enables a user to lift and tilt the seat portion forwardly while simultaneously moving a seat back of the apparatus from a reclined to a fully upright position. An extendable leg rest assembly allows the user to kneel thereon to further relieve lower back stress during prolonged periods of seating and to better enable the seat occupant to make use of a laptop computer or other equipment positioned in front of the occupant. The seat apparatus therefore provides a plurality of different seating positions for the occupant, thus enhancing the comfort of the occupant during prolonged seating periods and while the seat occupant is performing various tasks.
