2004 DeVille Headrests

I wanted to remove the headrest from my 04 caddy deville to put on a back of the seat coathanger. I cannot for the life of me figure them out. They come up about 4 clicks and then just stop.

Pull the head retraint all the way up. On the side opposite of the notches on the rods of the head restraint, there will be two tabs that must pushed to remove the head restraint from the seat.

Tester

Sorry, but no. That was the first thing I looked for, as it is the way all others I have ever owned were. No tabs, buttons, or anything.
