You weren't using that whole seat, were you? The Washington Post reports:
Airbus has filed a seat patent that appears to pack people in without all the clunky cushions and awkward folding tables, in an apparent bid to save valuable space on its aircraft.
Its cushions are shaped liked bicycle saddles, and when the seats aren't being used, they fold vertically to save space. Cutting down all that "bulk," as the patent application puts it, lets you do a lot more with the limited real estate on board.
Go take a look at the whole patent. It just looks terrible.
