Toddler protection

[BobJob]

Does anyone have any recommendations for (waterproof) car seat covers?

Specifically for the back seats to protect from the kids. Would need to allow access to the iso fittings.

For the floor I was looking at these: https://smile.amazon.co.uk/dp/B0198DB8G4

Scotchguard works well on cloth seats, I used it on the Alcantara (like suede) seats on my old 2010 Prius, liquid just beads off it. Not sure if they do a leather protector.
