Well, we purchased our Pilot EX-L this weekend and absolutely LOVE IT!!! But i do have a concern with installing our Brittax Marathon carseat directly on the second row leather seats. I'm concerned with the carseat damaging the leather or leaving a lasting imprint. We use the "latch system and tether" to secure the carseat but do you think it will damage the leather? I'm considering placing some type of mat between the carseat and leather but not sure if this would make it less safe. I have the same concern when using a booster as well but there isnt nearly as much pressure applied to the seat vs the actual carseat. Are there any aftermarket accessories specifically designed to tackle this problem? Your help would be greatly appreciated.
