Air France Frequence Plus - YUL-CDG, Biz class,type of seat?

I heard that they have the very old seat on this route. Can anybody tell me if it is true.
There is a B747 flight and a B777.

Please, advice.

Thanks !!!

No, it's not a very old seat. Only a few year old. It's a lie-flat seat slightly angled but quite confortable. On the various A/C you may find a slightly different version of the seat called NEV 1, 2 or 3 (NEV1 is a little bit more angled in the older version, most likely found on the 747).
