To prevent whiplash there should be as little distance between your head and the rest/restraint as possible so your neck moves back as little as possible when hit from behind. So resting your head on it makes the distance 0.

The E90 Sport seats got a better whiplash rating in crash tests than the normal seats due to the headrests being closer to the drivers head.

Page 49 of the F30 manual says it should be as close as possible to your head.


On teh cars like the 7 Series with active head restraints, the crash system automatically pushes the head restraint forward so it is against or very close to the head to prevent injury.
