These seat savers sure saved us!
We used 3 of these mats under our Radian car seats, and they completely protected our tan leather seats -- from indentations, stains, food spills, and even vomit (gross, but it happens). We used these for 3 years, removing them rarely to shake out crumbs, and we recently removed them completely as our kids graduated out of their Radians. Only slight indentations from where the car seats were, and those went away quickly.To me the only drawback is that they made installation of the 3-across car seats more complicated because I had to find a path not only between seats but through thick, overlapping mats when attaching to LATCH or buckles. But that felt like a small price to pay for the protection they offered our car.
