The US 767 Envoy seats are the 170 degree recline, flat on an angle seat. Lots of US FFers don't like the 767 seat nearly as much as the A330 true horizontal flat seat in part because of that 10 degree difference.

The old A330 seats in what was generally referred to as row 1 started life as international FC under Wolf. They were a true 180 degree recline, horizontal seat when fully reclined and believe it or not there is a difference between a 170 degree recline and a true flat, horizontal seat for sleeping.
