Two in my car and two in my husband. In mine I put it on the passenger side headrest for easy storage of my purse. My husband had it on the driver's side so the passenger side bag wouldn't be on the floor under his feet. They come with removable water bottle "hangers" which are not needed in our cars as we have cup holders between the rear seats but would be nice for those with a smaller car that has less room to stow passengers in the back seats. I took some friends for brunch who were so impressed they ordered the next day!
