In an illustrative embodiment, an aircraft seatback pocket spring provides a pre-loaded spring force for holding the pocket closed. The pocket spring may include a length of a wire extending between inner surfaces of frame members on either side of the seat and forming an upper edge of the pocket. Second lengths of wire may extend from ends of the first length of wire in a vertical direction to form side edges of the seatback pocket. Coils may be formed at each end of the second lengths of wire and may be mounted to receiving elements provided on inner surfaces of the frame members. Extension members extending from the coils may contact a contact point on the same or proximate frame members to maintain the pre-loaded spring force on the coils.
