L'avis de Qatar Airways Boeing B787 Dreamliner 254pax de Frank B (#28016)

Very good seat like most other seats in business class. The A and K seats are good for solo travelers, E and F is better for people travelling together (unless a window is important).
One of the best sleeper seats in any business class I have tried, possibly with the exception of QR's 777 which does not have the narrow foot well (but has less privacy for solo travelers)
