Front Seat Head Restraint problems of the 2006 Mercury Mariner

This complaint regards the 2006 Mercury Mariner that I am leasing. The vehicle was leased beginning in April, 2006 from holman Lincoln-Mercury in mt. Laurel, new jersey. My wife, the principal driver of this vehicle complained about the head restraints preventing her from keeping her head straight up while driving. The Mariner's head restraints project forward preventing the driver from keeping his/her head straight up while driving. This is very uncomfortable as one's head is bent forward. Sometime in August, I returned to holman and met with mr. David burns, the service manager. He looked at the head restraints and agreed that they projected forward. He and I then looked at all the other Mercury Mariners on the lot (about 20) and found that all of them had the same restraints. We also checked other model new vehicles on the lot and found that all of the restraints were straight up as one would expect. Mr. Burns then checked to see if Ford had any issues with the restraints on the Mariner but could not find any. I can only say that when I drive the vehicle, I agree with my wife that the headrest prevents me from driving in a comfortable position. Is this a safety hazard? I would appreciate your looking into this matter and giving me your opinion.
