headrest replacement options?

[Charudatt <charu@iced.com>]

After reading the list for a few weeks I've seen no discussion of the
design and utility of standard Audi head-rests so I'll ask (in the hope
that this is not something already beaten to death and a total waste of
bandwidth): does anyone else think that the standard headrests are just
about useless? 

I used to drive a VW jetta with recaros and it's headrests were way
better. Even the toyota I drove before that had more functional
headrests than my 94 100S- I have to put my head way back even for my
head to touch the rest.

Are there alternatives? Can I replace just the headrests without
replacing the entire seat? Any leads appreciated.

TIA.
