Just want to add that, for the passenger, being able to adjust the recline of the seat back makes a pretty significant difference in comfort. I was never uncomfortable in the old seats, but sliding the seat one click forward, and reclining just a hair made all the difference in the world.
I owe a HUGE thank you to (in no particular order) @Painter, @lrobbi, @DKF Texas, @Shatneyman, @WOLF, @Tripod, @MiM, @av8ingtom, @Ross, @TheRock, and @Slingrazor. Your generosity knows no bounds. Merry Christmas everyone (or Happy Hanukkah / happy solstice /happy Saturday based on your particular preferences)!!!!
