Korean Air's oldest 777-300ER business cabin, the Prestige Sleeper, is a fully flat 180-degree bed seat in a 2-3-2 layout with 56 seats. Seats are 20.1 inches (51 cm) wide with a 74-inch (188 cm) pitch and convert to a flat bed of 73 inches (185 cm). The layout is not staggered, so window and middle seats must step past a neighbour to reach the aisle, and there are no privacy doors or shells — just low dividers between seats. Each seat has a 15.4-inch LCD monitor with a touchscreen remote and one-touch recline controls.
