A Headrest is a vehicle is found on top of the driver and the passenger seats in most vehicles, but over some time we have been seeing them over rear seats too. These headrests can be adjusted keeping in mind the drivers and the passengers comfort level. These headrests are detachable, and are made using the same material the car seats are. These headrests were designed in a way that they can help protect the head area during an accident. As most accidents have a huge impact on the vehicle, which results movement of the body; the headrest helps in limiting that impact for the head areas; so the least damage done. These headrests can save drivers and passengers from an injury that can last a lifetime. So these headrests should be aligned with your head, and that is why they are adjustable, to ensure that they are set at the perfect angle.
