ATandem seating consists of individual seat units connected in a row by a shared structural beam, with single or double armrests between seats depending on configuration. Each seat unit is a defined individual space — users do not slide into each other as they would on a continuous sofa. Tandem seating is used in high-volume waiting areas — airports, healthcare facilities, government offices, and large corporate lobbies — where capacity, durability, and controlled per-seat definition are priorities. It is easier to clean than sofas, can be configured in virtually any length, and often includes tablet arms or charging accessories. The disadvantage is that it is less visually welcoming than upholstered lounge chairs and sofas, which is why tandem seating is typically used in functional waiting areas rather than reception or breakout environments.
