How exactly does one sleep in that seat? Diagonally, with feet where your bum would normally be while seated? It looks more like a square than a proper, long bed. I can hardly believe airline would introduce this though... it seems as though there is lots of wasted space that goes unused when not sleeping, than could have been used to squeeze more pax in. Maybe first class, although it looks a bit too claustrophobic for F IMHO. I like all the legroom one receives in Club World, and not having to stuff my legs into an alcove in the seat in front of me.
