Review on Headrest Universal Storage Vehicle Backseat Interior Accessories by Andrew Schreider

That's great! I would just give a word of warning before strapping to the bar to make sure your headrest is fully removable, otherwise I don't see any way to remove it any other way. Once locked, the "hole" for the bar is serrated to prevent it from falling. I used them to hang up grocery bags when I got home from shopping. It's a 17-mile drive and the bags are usually on the floor of the back seat. Grandkids love the water bottle holder!
