United Airlines has announced a new seat offering called the Relax Row, set to debut next year and intended to make falling asleep and getting comfy in economy more comfortable. The seats will have adjustable leg rests that can fold up to a 90-degree angle, giving passengers more room to sleep or stretch out. The move makes United Airlines the first North American airline to offer lie-flat seating in economy class. The Relax Row will be offered on over 200 Boeing 787 and 777 widebody aircraft by 2030.
