I have two flights booked in business in December on the A350-900 with my partner, and both cabins are empty at this point. A few questions for my seat selection:

• Is it possible to have a conversation in the middle seats? If not, then we may as go for the windows.
• Is the foot box larger in the bulkheads, like it is on the 777s? The wiki doesn't specify, but I'm 6'5"/198cm tall and want to maximize sleeping space. If so 20 D/G (if I can get them) are appealing. (It seems 11 D/G are not worth the toilet trade-off.)

Thanks!
