The seat also comprises a seat base supporting the moveable seat carriage thereupon and a support member moveable between a retracted configuration and an extended configuration, wherein a first end of the support member is coupled to the moveable seat carriage and a second end of the support member is coupled to the seat base. The seat also comprises an actuator to move the moveable seat carriage relative to the seat base to thereby transition the seat between an upright and a reclined position, with the movement of the seat carriage driving the support member between the retracted configuration and the extended configuration, wherein the support member stiffens the seat as the seat transitions away from the upright to the reclined position and while in the reclined position.
