>Compared with the standard lavatories, Smart-Lav brings 5.5 additional inches for more seats and 10 additional inches for recline space.

Yet they claim it "allows up to 6 additional seats in the cabin". Assuming they're in a row, I fail to see how you can fit a seat in 5.5 inches.

>The interior of Smart-Lav has been designed to enhance the spaciousness and the hygiene perception by the passengers.

It's blatantly focusing on perceptions over reality. I got sick in a plane with a similar layout(I think it was with Emirates) and I remember it being significantly more uncomfortable than any other plane I'd been on, and I think I managed to hit my head while throwing up.
