A flight attendant seat comprises a carrier having a guide with opposed first and second ends, and a storage compartment receiving the guide first end. The guide provides guidance along its length between its first and second ends. The seat comprises a plurality of segments, each slidingly mounted to the guide to allow a sliding movement of the segments along the guide and relative to the carrier device between a stored position of the segments within the storage compartment, and an exposed position of the segments. A seat element is pivotally mounted to a first of the segments pivotable between an inoperative and operative seat forming position. At least one backrest is mounted to at least a second of the segments. With the segments in their exposed position, the seat element, when pivoted to its operative position, together with the backrest(s), can be used as a flight attendant seat.
