So that's where a headrest comes in.

I've got five inches of adjustment here in order to get the headrest in the right place.

So if you watch this chair as I recline, the headrest comes up to meet my neck.

Now headrest is a challenge because you want it to adjust enough so that it'll fit, you know, a tall guy and a short girl.

But to do that, if you have any amount of recline, it gets to the point where you need a headrest because nearly always, automatically hold your head in a vertical position, see?

But then I knew from experience and looking around in offices where there were chairs with headrests that nobody would ever bother to reach back and turn a knob and adjust the headrest to put it in position.
