A seat base assembly for an aircraft seat includes parallel rails (104) attached to an aircraft bulkhead, each rail including a slot extending vertically within the rail. The seat (e.g., seatback and seat frame) is attached to a sled (302) capable of vertical translation relative to the bulkhead via slidable members that translate along the slots. The sled (302) includes a hole for accommodating a locking pin controllable by the seat occupant. A metering plate (108) attached to the seat base (106) behind the sled (302) is folded over a lateral axis into a forward and rear layer, the forward layer including holes for the locking pin wherein each hole corresponds to a desired seat height to which the seat may be adjusted by securing the locking pin through the sled hole (308) and metering hole. In response to an impact event, the metering plate (108) deforms to absorb impact energy and control downward deceleration of the seat.
