I'm 6'2" and recently rode in 14A on SIN-ICN on the 77W. I loved the privacy of no one next to you, I didn't mind being so close to the galley, but I just barely fit. I had to lounge and lay at an angle to just fit. I was able to be comfortable, but it would not be comfy if you were much taller.
Here is a pic of me with the seat reclined a bit. The only comfortable position I could get was with my legs up on the far bench at an angle as shown.
Here is a pic of me laying down with the seat in fully flat bed mode.
I've got more pics of the suite, the cabin and whatnot - but I won't have them up on-line until I get to that point in my trip report (probably another week or so).
