Headrest question

Might be dumb but I installed a cover on my headrest and it only seems fully locked in the highest position. Passenger side seems the same with no cover. Is this part of the active headrest?
Thanks

 

I have an 07 access cab and the bucket seat headrests have three (maybe 4) adjustment "clicks". My wife is considerably smaller then me so we always are adjusting ours. Also, I have seat covers with little headrest "booties".

So, I think something is wrong with yours???

 

It goes into the three positions but when on the lowest you can move it up with out pressing anything . Seems like that's what the manual says to do.

 

Oh. Yeah, we don't have to push anything to pull it up. But do to push it back down.
