The rear seats of my '20 Forester are currently occupied by car seats. I'd like to protect the backs of the front seats from the incessant kicking and stamping of children. I tried looking up protectors on Amazon, but that was an exercise in futility. What I'd like to get are some protectors that are likely to fit the forester seats in general shape, that are fairly durable. The Amazon recommended ones seem flimsy and ill-fitted. Any parents out there added something like this? Any recommendations?
