Your wife is pretty smart. A lot of people have been killed by that back window which is why all vehicles have head restraint nowadays. I have done a lot of research on seats because I worry about this too. It seems the 90's GM seats are the best fit. They have a slim design so you don't lose leg room or head room and are pretty comfy. Most other seats sacrifice leg room and head room but may be more comfortable for shorter people.
