The Envoy seats are wider than coach. They have a 2 x 2 x 2 configuration, where coach has 2 x 3 x 2. There's more leg room in Envoy as well, although I couldn't give exact dimensions. It's been a while since I have been on a 767, but if memory serves me correctly, the seats have the same grey pattern, but is lacking the red part in the middle. Instead it has the rectangular pattern sort of like coach, but is alternating blue and white. Does that make sense?
