So called lie-flat setas that are not flat at all. A slight open Z shape at about 170deg. Just like Emirates and KLM, these are angled lie flat seats.

The supposed lie flat beds don't lie completely flat but are flat at about 170 degrees; slightly inclined. I prefer proper flat. There is also limited leg room for taller people, so my feet kept bumping against the seat in front. Not very comfortable. It is essentialy the same experience as in KLM business class. Beware of the 767s which are very outdated and have tired seats, toilets and IFE. B767s have a 2-1-2 arrangement and B777s have 2-3-2. The former can be quite nice if you get the centre seat as a single traveller. The overhead storage is sufficient - you can get fairly decent sized carry on stowed here. The cabin crew are good to excellent in Premier World.

The seats were comfortable even though they seemed narrower and length was not very good. My partner who is 1.85m couldn't stretch his legs in a lying position, they were up against the wall, not very comfortable. The bed was also comfortable, but only had a short sleep, not a whole night. Entertainment system was a modern personalised system with lots of film choice.

B767 and B777 aircraft used on NBO-LHR-NBO sectors all fitted with comfortable seat that reclines to lie flat, albeit the seat back remains at an angle. For me, this is in actual fact more comfortable than a completely lie-flat seat as it allowed my head to remain higher than the rest of my body. In bed mode, the seat is equally comfortable lying on side or back, although width and height might cause problems to larger passengers.
