The term "flat bed" is used interchangeably with "lie-flat seat" and emphasises that the seat becomes a genuine sleeping surface rather than simply an aggressively reclined chair. Airlines market their business class products using terms like "fully flat bed," "180-degree flat bed," or simply "business class bed."
Modern flat bed products include mattress pads, duvets, full-size pillows, and turn-down service to create the most bed-like experience possible. Some first class products go further with separate beds and chairs (Singapore Airlines Suites) or dedicated sleeping compartments.
The flat bed is the defining feature that separates modern long-haul business class from premium economy and domestic business class. It’s the primary reason business class commands a significant premium on overnight flights — the ability to sleep horizontally and arrive rested is transformative for long-haul travel.
