My husband has a 2015 and has been using his headrest backwards for comfort. We recently upgraded our car seats (shopped for the shortest front to back to allow maximum driver room) and he can either be uncomfortable by having the driver seat forward or be uncomfortable by having the headrest in the correct position. Is there a good aftermarket headrest that is slimmer in the front side so he can be somewhat comfortable? Both car seats are rear facing and have to be for the foreseeable future.
