The headrest has on obvious button to adjust the height and another button kinda hidden to remove the headrest. The black plastic ring at the base where the metal poles insert into the seat is where the two buttons. You probably noticed the obvious on that sticks out of the side of one of the rings. The other plastic ring contains a similar button that is not noticeable due to it being flush with the side of the plastic ring. Adjust the headrest to its highest position, then locate the "hidden" button on the other plastic ring and depress it while lifting on the headrest and it should come out.

Most volvo headrest can be removed by releasing the catches which are on the back of the headrest on some models and on the front on others I believe on 960 they are on the back. To release the seat on a 960 look where the shafts should be then follow it down on the back where the seat back top stops then goes in press around that area you should be able to find the catch there pull up on the headrest while releasing the catch you have to do this on both sides. The headrest should come off this also works on 740 and 760 series the volvo 780 is a different story the only way to get the headrest off on that is to disassemble the seat
