Hi: Am I the only one or is the center headrest not adjustable? I cannot move it up or down even when I push the button on the side. Is there a way to remove it completely (Last resort hacksaw) ? I will never have an adult in the middle anyway. With the rear window already small, I estimate approx 30% of the rearview mirror perspective is completely blocked by the three headrests.

It has two positions plus it comes out completely. To move it you need to BOTH press the large button on one support, and use a small tool to press in the tiny square button on the other support.

On the normal position it blocks rear view somewhat. On the bottom position it goes all the way against the seat back and is all the way out of my rear view.

The other two headrests also go all the way down to the seat back using the same technique.

Fabulous..big difference it makes, now that the big head rests are removed and stowed away in the boot. Thanks a bunch!
