Seat surrounding furniture (commonly known as shells) is intended to enhance passenger comfort and privacy. They can offer additional space for reclining the seat into a bed position, additional stowage, amenities, etc. Often some amenities are located on the furniture including the front row monument installed in front of the passenger seat.

The unit structures are not directly integrated into the main fuselage and do not offer main supports for aircraft integrity.
