United Airlines’ is deploying a slew of new ergonomically-attuned seats for Economy and Economy Plus on hundreds of aircraft serving the United States, Canada, Central America and the Caribbean.

And it’s not just full-size craft that are set to get them. The new seat type made its debut on a United Express CRJ700 operated by SkyWest.

United says the seats are; more ergonomic, with supportive cushioning; have more seat-back storage space and sculpted contouring.

All of this comes in a package that the carrier touts as more environmentally friendly – this because the seat-sets weigh less. That translates into less fuel burn.

Developed in conjunction with the travel and transport design consultant Priestmangoode, United ultimately plans to deploy some 60,000 of the new seats, installing them on more than 500 aircraft.
