Stop in for a cup of coffee

I’m not sure I understand the question. Why would you want that?

A head rest that isn't integrally attached to the back rest frame offers zero protection in a collision. Worthless unless all you want to do is sleep against it.

Well, I just wondered if some of you guys where familiar with it, it was no more than that in the question.

The reason would be to save ones neck if hit from behind.
