I've got a travall guard that fits above the back seats in my focus estate,I think it's good quality, very solidly built and because it doesn't go down the back of the seats I can put the seats down without removing it (which also serves the purpose of an 'escape door' if in an accident and the boot cannot be opened). It was easy to fit into the fittings in my car and was quite competitive in price I seem to remember. I bought my barjo tailgate and divider second hand but couldn't get a rear seat guard at the time.
