Experienced on this
Wow, I finally get to use my knowledge for my first post!
Just did the same trip in this seat on Sat. All comments are correct, especially those about seat width, hardness and the A/V screen. ALL of the bulkhead seats are hard. So hard in fact that I can barely tolerate them with my skinny behind. I am not even close to skinny but carry little posterior padding (some call my condition "Noassatol"). I'm 6"0" and 190 lbs so consider this when booking the seat for almost 16 hrs.
Legroom is great but you have to stake your clain to the turf. I like to set my small wheeled computer bag in front of me as a ottoman to discourage infiltration into my space. Beverage/Food Service carts will also bump you.
Be nice to the attendants and they will try to keep the space in front of you from becoming the hangout it tends to become. On my flight our lead FA was diligent about it to reward my seatmate for moving here to accomodate another pax.
Final note: Place your blanket and pillow under your butt and the seat becomes more tolerable.^
All that said, I gladly took this seat rather than a middle seat in non-bulkhead.
