How do I remove the headrest from the front seats so that I can put seatcovers?

Most headrests have a spring clip as the safety latch. If there is no visible push button there will be a hidden release latch. Carefully examine both plastic caps the headrest posts sit in. Look for a pin hole. If there is no pin hole the caps are 'push on' covers. They should lever off and reveal either a push button or a pin hole.
With the pin hole, insert an unfolded paper clip to release the locking spring.

There is a button location underneath the headrest. Lift headrest as high as possible, feel for the button, press and continue to lift up.

Just removed them on a 2005 Sebring sedan. Easier with two people but one can manage just fine. The trick is a tiny hole in the plastic "sleeves" that the metal posts on the headrest slide into. You'll need a small poking device-Allen wrench, drill bit, tiny screw driver, whatever. The hole is on the right side of the right side sleeve on each headrest (as you're sitting in the back seat facing forward) and is perpendicular to the direction the metal rods go into the sleeves. Insert your small poker and depress the plastic button on the other plastic sleeve simultaneously while your helper pulls up on the headrest.

If there is no button on side or in back, you just have to pry it straight up with a padded strong flat tool.

On your headrest, there will either be a push button that you can push to release the headrest, or on some models, there's actually a tiny hole that you will need to push something like a paperclip into to release the headrest

Im doing the same thing.. Push the headrest full forward, then lift hard to get past last indent in pole.. This worked for the front as well.. i also could not find a hole to push

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

There Is A Button At The Bottom Of One Of The Silver Posts Hold It The Whole Time You Are Lifting The Headrest Out. The Little Button Is Almost Always Grey Plastic.

Look at the top of ur seat, between the two shafts of ur headrest. Beside one of the posts is a black plastic base on which one side has a button u push. That allows u to remove the headrest. U might have to jimmy side to side a bit as they are somewhat hard to remove at times, just do so with ur finger pushing the release mechanism.

Usea small flat screwdriverand run down along side the inside of the headrest rod. You will unclip 1 side and the rod will release. Do the same on the other and the headrest will come off. When you want to put back on just install and push down. Follow same procedure when you want to remove again. It is a little touchy but as soom as you remove 1 you will become a expert. I have done hundreds of those in the past couple years.
