I hope there are two armrests rather than just on one side. The EY A380 aisle/fwd facing J seats had a tiny armrest and on one side with the divider and you can barely sit comfortably with that. Heres hoping that smaller cushioned part comes up like on the B787. Also, from one of the above photos it seems that the lifejacket maybe under that part as there is a "pull" tab on it.
Further, has anyone noticed how on the window, and middle love seats in the photo, the protrusion from the side table from the seat "facing you" is there under the screen. But on the aisle-window seats and couple seats sharing the large centre table have no ledge/protrusion under the screen.
