I Got tired of the head rests sticking up when I folded the rear seats, so I figured out how to remove them and it was very easy. (this is necessary for my upcoming post "Removable rear seats...)
This is the back of the rear head rest from the cargo area.
Use a small flat blade screwdriver to pry out the clip that holds in the head rest, it is the top black piece in this picture (there are 2 per head rest).
This is one of the clips.
Head rests removed.
Now the head rests don't stick up when you lay the seats down and gives you a little more room.
