headrestraint excessive angle

Contrary to many an uneducated opinion, the headrest/restraint does not need to actively force your head forward, its "supposed to lightly touch, or sit just behind the back of your head". Unlike some of the adjustable ones, the Mazda head restraints have enough padding and angle that when properly adjusted it can cause back and neck pain after repeated or lengthy use.

This issue seems to be less apparent on the leather seats.
