Oh I played with the seat controls on the extremely heavy tablet. And yes they could do the door on its own or the seat on its own. But due it being the size of a 1990s laptop it was left in is cradle and in doing so was too awkwardly angled to use comfortably.
Both flights reviewed above were day flights. On a recent J-class night flight I was able to put mattress, cushion and duvet in the side bins out of sight before I needed them later. That was impossible to do in F. Perhaps mainly as you say in that the bedding is thicker and better and take up more space. I didn't sleep on the F flight as I said hence my review didn't (and couldn't) compare the actual bedding.
An airy ceiling? Or luggage crammed at my feet? Gosh I know what I'd like but then I saw the post about the new A380 interiors in EK's J where they took away the side bins out back too!!! Gosh. Better to check all your baggage in if you want to fly with EK then. Now that's what I call ridiculous I'm sorry.
