Anyone who has spent time with a child can agree that kids tend to be messy. That extends to time spent on the road, when snacks can get all over your car's upholstery. Child seats and boosters can also indent or stretch out your car's seats, leaving them looking far from perfect.

Some parents try to avoid the mess by using child seat protectors designed to put a barrier between the vehicle's upholstery and whatever mess your kids create. Not everyone agrees that these seat protectors are a good idea, however. Here's what you need to know.

What a Child Seat Protector Mat Is

You may have seen ads for something called a car seat protector or a child seat protector. This type of product often takes the form of a mat and is intended to sit between a child's car seat and your vehicle's upholstery, ideally offering a way to reduce damage and stains from spills, blowouts, or other messes.

Some car seat protectors also try to prevent creases and dents on seats by evenly distributing the pressure of the child seat. While there are car manufacturers that sell child seat protectors specifically for their vehicles, there are also plenty of third-party options.

Objections to Car Seat Protectors

Child seats are tested to ensure they comply with the Federal Motor Vehicle Safety Standards per the National Highway Traffic Safety Administration, but those tests assume the child seat is being used correctly and as tested. Car seat protectors, however, could obstruct the proper installation of a car seat. This may affect how the car seat containing your child performs in a collision.

According to customer-advocacy group Consumer Reports, seat-protection mats could adversely affect how well child car seats are installed, potentially reducing a child seat's effectiveness in a crash.

Additionally, even though child seats are tested to meet federal standards, accessories and car seat protectors aren't held to the same standards.

Do Your Research

Some car-seat manufacturers have guidelines about which accessories to use, while others, such as Diono or Clek, offer car seat protectors designed to work with their products.

One resource you might consider using for research is called Car Seats for the Littles. It's a group staffed by safety technicians focused on child-passenger safety. The organization offers a detailed chart online that explains which seat brands approve of car seat protectors.

How to Use a Child Seat Protector Properly

If you decide to use a car seat protector, ensure it doesn't cover the lower anchor attachment points in the vehicle and doesn't get in the way of the top tether.

Proper child-seat installation requires that the child seat is not able to move more than 1 inch when installed. The extra material of a child seat protector could interfere with that requirement.

Car Seats for Littles advises seat-protector users to install the protector first and then install the child seat, ensuring that there's less than 1 inch of seat movement in any direction. Try sliding the protector out from beneath the seat to ensure there is still less than 1 inch of seat movement.

Check Your Linen Closet Instead

Some parents may not be interested in paying for a product specifically made for the purpose of preserving their upholstery and are simply looking for an easy way to avoid unnecessary mess in the car.

For a cheap and easy way to reduce staining and dampness from spills, place a towel between the car seat and the child restraint. Towels are thin and flexible, so they're unlikely to obstruct a latch point, and they'll also absorb light spills to help keep your car's interior clean.
