Thai Airways Royal Orchid Plus - LAX-BKK in Business - Best Seats?

...for sleeping and quiet? Thanks in advance for any suggestions. Happy New Year!!

As Seat Guru points out, there are actually two business cabins on that flight, with the forward one being smaller and somewhat quieter than the second. It's a 2-2-2 configuration, which means a center seat will keep your fellow passenger from having to hop over you to reach the toilet. You won't miss anything in the way of a view by choosing one of those. Naturally that cabin fills first.
