I had my first flight in The Room, I am not super impressed. It is a good seat, better than the staggered, but not as good as Q Suites for sure.
When you recline the seat, it is also moved down, meaning the table is really too high up to recline the seat while dining. Someone did realise this and made a dining position that lifts the seat and tilt it forward from the standard position. It works for the table location, ut is not very comfortable.
The seats is not great for lounging, but some strategically placed cushions helps a lot.
The sleeping surface is not long (178cm here) I either had to sleep at an angle, or on the side and curl up my legs. Sleeping at an angle you will be on top of the seat belt location, but it is done in a way that you don't notice..
