A 3-seat seating grouping is presented that includes a center seat configured for vertical translation from a lower position to a raised position when converted from an upright to an inclined mode. The center seat can be disposed between an aft-facing seating assembly and a fore-facing seating assembly, and be configured to overlap both when in a lie-flat position. Non-overlapping footspace can be shared between a center passenger and an aft-facing passenger. When upright, a center seat can be at the same height as a non-translating aft- or fore-facing seat, reducing loads on a seat track during aircraft take-off. Seats within the 3-seat group can be angled or aligned with respect to cabin longitudinal axis. A plurality of 3-seat groups can be combined in various orientations to span a cabin. Groups can be arranged to mirror each other to maximize seating directed to an aisle.
