Plenty of legroom and width, but very uncomfortable for sleeping. The seats do not recline, the seat back is at a fixed angle, you sort of slide down, moving your bottom forward pushing your head down into your chest. Four of us travelling all complained about the sleep quality. Air France spent a lot of money on these seats but it is hard to believe the decision makers tried to sleep in the seats. Flew the A380 LAX-Paris-Johannesberg. Configured 2-3-2 on the upper deck. You have to walk back though an economy to get to the lavs but that was not a problem. We paid many dollars to upgrade to business for the return flight. Last year we flew Premium Economy on Qantas whose large seats recline probably twice as far as standard economy and were quite comfortable.
