Which W123's (if any) came factory equipped with rear seat headrests? I have seen a few Benz's with rear headrests and they look classy. It gives them almost a limousine look.
"...but really are they worth all that work?"The head rest and rods attached to the headrest of a w126 will work but the mounting hardware on the rear seat frame will not work.
I am going to agree to disagree now....but here are photos of the rear head rests on a w126 seat frame and the seat frame of a w123 with "correct" head rest....NOT THE SAME!!!

Now if you had both seat frames, welder, sawzall, rivet gun, braces and sewing machine to redo the cover...then you could...but really are they worth all that work?
I totally agree!! But I would imagine they would only help if the head rests were properly secured to the seat frame. I don't think zipped tied head rests would provide the same protection."...but really are they worth all that work?"
Only if there is a rear passenger during a heavy rear end accident. Without the rear headrest, there is a good chance of "whiplash" or worse.

Well done, if you can source the correct metal rods for the pointed ear headrests from a w116 or w123 rear seat, you're golden. You might find that the front headrest rods do not position the headrest cushion forward enough. Try lifting up and tilting the cushion forward to see if it fits better.Installed one rear headrest in my 240D today. Until I install the other, I may have the only W123 in the world with three headrests.
Taking a long trip in July with a rear passenger, so I thought now would be the time to install at least one. Took me 5 hours start to finish, but that included treating the rust on the seat frames and a trip to the hardware store.
As mentioned in my earlier post, I took all the parts I needed from the front seats of a W123: headrest, rails, etc.
The height is adjustable, but it would be best to remove the seat back to do so. It stands pretty tall even when all the way down, so I am not sure it ever will need to be any higher than shown in the photo.
Here are a few photos
