do what i did. i tried it going from under and using a flathead, but i found out this works the best. pull up on the headrest to creat tension. then use a hacksaw blade and gently slide it down the front. be careful though cause the blade is stiff and can break, just let it bow/bent a little. then slide it down you push down on it, making sure you still in the middle of the metal post. remember to pull up while sliding down the hacksaw blade.
