United Airlines announces new 'Relax Row' economy seats that convert to a couch

United Airlines introduced a new option in economy, called the Relax Row.

The three seats in the row work like a pull-out couch with adjustable leg rests.

There will be 12 of these sections on hundreds of Boeing 787s by 2027, with plans to expand by 2030.

Relax Row passengers will receive special amenities, like a custom-fitted mattress pad, blanket, and two extra pillows.

Families also get a plush toy and a children's travel kit.

United is the first North American airline to offer lie-flat seating in economy class.

The airline has not revealed the cost for the Relax Row seats.
