If you're talking about the new seat design which they are now replacing, I can help ya' out! I've flown on it many-a time!
The seat is extremely comfortable, all electric controlls, and both the seat back and leg rest nearly go to 180 deg. The legrest stretches out far-I'd say a good 3.5 feet or so. Far enough that I can have it fully extended, and still not be able to touch the bottom (I'm 6').
The seat controls are easy to see, use, etc., and the PTV with personal video player, lumbar, phone, and adjustable reading lamp make the seat just that much better.
Gotta love that seat...
