The teaser video shows more of a 'waterfall' design with the seat in three cushioned sections - the back, the base, and the bit which hangs down at the front (if I may invoke such technical jargon).

I'd find it hard to imagine there would not be independent controls for these, so that the bit which hangs down at the front could be raised and the back reclined into a 'lazy Z' sundeck-style position. I suspect the person saying there is no leggiest might be basing their judgement on the concept AirTek cutaway?
