2015 IIHS Booster Ratings: Ranking the Safest Boosters

FacebooktwittermailFacebooktwittermail
IIHS Awards “Best Bet” to 20 Models of Child Booster SeatsJenny

Every year, the list of great boosters for kids gets bigger and bigger, according to the Insurance Institute of Highway Safety. Parents and caregivers have an easier task of finding a belt-positioning booster seat that will provide their child with a safe seat belt fit. The IIHS evaluated 23 highback and backless models for optimum seat belt fit on a 6 year old dummy; fit is determined by how well the seat belt lies across the shoulder and thighs. The booster is given a rating of “Best Bet,” “Good Bet,” “Check Fit,” or “Not Recommended.”

Booster seats are for an age group of kids (about 5-11) that are commonly known as the “forgotten kids” of child passenger safety. Well, *we* haven’t forgotten them, but they slide through the cracks of safety because they’re too big for convertible carseats and too small for the vehicle seat belt to fit safely. A recent Safe Kids survey found that 86% of parents switched their kids to just the vehicle seat belt before it fit properly. While you may frequently hear that it’s OK to move your child to a vehicle seat belt when he’s 4’9″ tall, as parents, we at CarseatBlog know our children didn’t fit in our vehicles using just the seat belt at that minimum height suggestion. Remember, these are adult seat belts so your kids must be adult-sized to use them. Until then, booster seats are the way to go.

What do the ratings mean? A “Best Bet” rating means it should correctly position the seat belt on a typical 4-8 year old child in most vehicles. But remember, your vehicle may not be “most” vehicles and may have a different belt geometry. Always try before you buy, if you can, and hold onto the box and receipt in case you need to return the booster.

A “Good Bet” means that the belt fit will be acceptable in most vehicles and these boosters shouldn’t be automatically shunned because they aren’t “top tier.” “Check Fit” means just that: it may fit a larger child better than a smaller child in some vehicles or vice versa. I’ve used “Check Fit” boosters quite successfully before with my kids in my cars—it definitely doesn’t mean you should chuck the seat out with the baby’s bathwater.

Here’s an excellent example of a booster, the Graco 4Ever in backless mode, that fits well in one vehicle but not in another. You can see that in the vehicle on the left, the shoulder belt fit is poor whereas in the vehicle on the right, the shoulder belt fit is excellent. The lap belt fit in both vehicles is excellent. We need to have excellent fit for both shoulder belt AND lap belt in order for the booster seat to be safe.

Please note that many very good boosters are not included in our Recommended Carseats list.  This may be simply because we have not yet reviewed them.  In other cases, we may feel they were very good products, but just didn’t offer quite as much as others we did recommend.  Even if a product is not listed as a “CarseatBlog Recommended Seat,” it may still be worth consideration if it works well with your child and vehicle.
