Is there a company who makes aftermarket headrests that can be added to the rear bench seat in my F-150? My bench seat does not have any headrests, and since my kids sit in the back, I want something to protect them from a rear end collision. I never cared when it was me or my friends, but once my kids sat back there it concerns me. Currently, using booster seats, and they are growing out of them quickly. Any links or ideas would be appreciated.
