It does it job, I have light beige leather interior and I have seen no issues from imprints or stains from the material. I use this in my car and my wife uses it in her SUV which also has light leather interior.

Protects from car seat damage, soil stains, and multiple uses. When car seat isn't installed I use to protect the seat from sauces and liquids while transferring things in my car... The weight flap makes it more secure..

Since we have only had our Super Mats for a short time, I cannot provide a long-term review. However, I have 2 children that are constantly putting feet/shoes on the seats and my leather seats were suffering for it. Rather than keep chiding them, I bought these. I do with there was an option for tan/brown rather than black. They have pockets on the front that the kids can use for snacks, crayons, whatever.They are a bit wide for my back seats, but we just slightly shift them to reach the seat belt buckles.So far, so good!
