HeadRest Replacement , Drivers side

I have a 1999 Cavalier and the headrest on the drivers side has a rip in it. I was going to replace it with one from the wrecking yard but can't see how the headrest comes off. I am thinking that it doesn't unless you remove the seatcover? Is this right? Is there another way to put in a new headrest without seat replacement? Or ...
Any help please...
Thanks

Anyone? Does the headrest come off without taking the seat apart?

Seriously. Does anyone know how the headrest comes off. On my other cars it just lifts out or there is a little lever/clip and it comes off.
Anyone know:shakehead?
