An aircraft seat with tilt-shift functionality includes a backrest frame pivotably mounted to the seat frame, the backrest frame having rollers set into its upright end that translate through slots in the seat frame and lateral slots in its forward end capable of accepting sliders attached to the seatpan. When a passenger leans backward in the seat, tilting the backrest frame backward and downward, a shift linkage below the backrest frame translates the backward tilt to a forward shift of the seatpan forward to enhance the comfort of the passenger. The aircraft seat may further be capable of longitudinal and lateral translation as well as a full 360-degree swivel.
