  • Car Seat Buying Guide

    Children under the age of 10 require a car seat to travel in a vehicle. The type of car seat your child needs is dependent on his or her height, age and weight. This guide helps you find the best baby seat or booster seat for your kids.

Rated 1 out of 5 by from Don't buy one! We bought this seat protector when we bought a car seat for our granddaughter. We now find that our leather seats have permanent black marks which we cannot remove. We would have had more protection from an old towel or picnic blanket. A complete waste of money and damaged car seats.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Exactly what we needed! We have had this for two years under a britax car seat. Now we are buying another to go under our new baby's seat. In preparation for the baby, we just got the car detailed, and the light grey leather of our Subaru Forester is still perfect under the mat. A great buy!

Rated 1 out of 5 by from do not buy This leaves black marks on leather seats which are very difficult to clean and impossible to clean completely.
