A seating unit (1) comprises a fixed housing (10) containing a primary seat with a reclinable back arranged to recline in such a manner that it remains within the housing. The seating unit is suitable for a aircraft cabin and may further comprise a leg-rest arranged to cooperate with the seating portion to form part of a substantially flat surface when the back is reclined in a substantially horizontal position. The seating unit may further comprise a secondary seat (3) positioned to face the primary seat, the secondary seat having a seating portion positioned to cooperate with the leg-rest of the primary seat to form a portion of the substantially flat surface when the back of the primary seat is reclined in the substantially horizontal position. Privacy between seats and use of available space within an aircraft cabin may be optimised by arranging at least some of the seats in an echelon.
