The rear seat headrests don't have the "secret" catch, just the fronts... there is a little slot on the opposite post hole mount from the one that has the height adjustment button, just push in on it with a small flatblade screwdriver at the same time as the height button, and the headrest lifts right out. took me a little while to figure that one out when I didn't have the seat cover instructions...

^^^Ok good to know, I was thinking that the seat needed to be taken apart to get them out.

Those look good. I need to readjust mine and Shirley's so they actually fit a little more snug
