The Cirrus seat is really, IMO, the best business class in the sky. It is the perfect blend of privacy, space, comfort and layout. Just flew CX in the same seat and slept great.
Agree! And the CX version of it is tops. AA's A321T F seat is a disappointing version -- really limited legroom (not length, but the limited vertical space within the footwell). Curious as to why it ended up that way.
