Got an op-up from Beijing back to Haneda today, and it happened to be a 77W with The Room, so I was finally able to try it out.

The firmness is not an issue for me. Had a nice nap reclining after dinner. I like the multiple positions you can set, but I can see why some people would think it's cramped in fully flat mode. I'm 173cm and that already felt a bit tight. If I turn and use the space closer to the aisle then it's a little roomier.

Didn't need the in-seat entertainment, the high-definition camera and the map were more than enough for me. Facing backwards was also really strange for take-off, but I got used to it pretty quickly. I do like how when fully-flat and facing backwards, my head is above my feet. Slightly more natural sleeping position than facing forward and having my head below my feet.
