After I labored in the hot August sun to put in our child seats, my wife took her Nissan Quest to the local fire station for an appointment to have the installation checked. Lucky for me, they said it was done as well as they had ever seen, but they still managed to tighten them down even more. They gave high praise to the Quest's safety features all around.

Anyhow, I can see this being an invaluable service to single mothers who cannot exert enough force or weight to the seats for a tight fit. Have your local fire dept do it for you!
