Couch
A couch is an upholstered seat designed for two or more people to sit or recline on. It typically has a back and arms, though designs vary.
Upholstery: The textile, leather, padding, and related materials covering furniture and vehicle interiors. It supplies the couch’s cushioning and finished outer surface.
Eight-way hand-tied springs: A suspension system in which each coil spring is tied to neighboring springs in eight directions. This traditional couch suspension links coils to spread loads across the seat.
Ancient Egyptian furniture: Furniture made in ancient Egypt, including beds, stools, chairs, and couches. Ancient Egyptian couches provide early examples of elevated furniture for reclining.
Living room: A room in a home used for relaxing and socializing. The couch commonly anchors the living room’s seating arrangement.
Loveseat: A small upholstered sofa designed primarily for two people. It is a compact alternative when a full-sized couch is unnecessary.
Seat cushion: A padded support placed on a chair, couch, or other seating surface. Its fill and firmness largely determine how a couch feels when occupied.
Pocket spring: A coil spring enclosed in an individual fabric pocket, allowing it to move largely independently. Some couch seats use pocketed coils for localized support.
Greek klínē: A Greek couch used for reclining, dining, and, in some settings, funerary display. The klínē joined reclining and social dining in a form ancestral to later couches.
Sofa bed: A couch designed to convert into a bed. It combines everyday seating with a place to sleep.
Armchair: A chair with supports for the arms. An armchair offers similar upholstery in a single-person seat.
