Headrest Removal ?

[Mapper]

I'm trying to put my sheepskins on my '05 convertible, but can't get the headrests off. I depress the release button and pull up but they will only come up a few inches and stop. This happens on both seats. Is there a secret or trick to removing them?
BTW. The headrests in my wife's '02 will come out all the way using the button press and pull up.
I've tried the search function here, but was unable to find any answer, so I'd really, really appreciate help. I don't want to butcher expensive sheepskins.
Thanks in advance.

I think, but not sure, I read somewhere that you have to fold the seats forward/backwards for the headrests to come completely off.

Just did a search and found this on PT Do-It-Yourself.net:

Front Seat Head Restraint

Removal Procedure

1. Raise head restraint slightly.

2. Insert a stiff wire into the hole on the right hand side head restraint sleeve/guide and push to release latch.

3. At the same time, press the button on the head restraint sleeve/guide left hand side and pull upward to release the head restraint.

4. Remove head restraint from seat back.

Hmm. I tried attaching a picture to clarify the procedure I found to remove the headrest.
CREWZIN put me on the right track with his response of another latch. But while trying to see where I could slip the stiff wire down to depress it, I saw the button which is flush with it's surround on the other upright. On the passenger seat that would be on the door side. I depressed it to see if it would move and to my surprise found it to be the latch that would release the headrest. And so, after pulling the headrest up all the way by use of the projecting button,by depressing it and pulling up, I was able to remove it.
So now my sheepskins can slip over the seat without further problems.
