The ratings on convertible carseats are in and . . . Consumer Reports agrees with the Blog! No, it’s really not *that* cold yet, but it is nice to have the publication that many parents trust agree with you on what the best convertible seat may be (see our Recommended Carseats page). Before I get to the CR top rated picks, let’s talk about what the “best” convertible carseat is. We say this all the time as techs, but it really does ring true, hence why it’s repeated so often. The best carseat is the one that fits your vehicle (the best), your child (the best), and your wallet. A carseat that, when installed, seems like it’s made for your vehicle AND your child, is the one that is the best carseat for you. It may not be what your neighbor or best friend uses and that’s important. A loosely installed carseat or one where you can’t easily adjust the harness to be snug on your child is not safe. Ultimately what the carseat does is contain your child in a crash. By being coupled to the vehicle, it allows the vehicle to crush and lengthens the ride down time, reducing your child’s chance for injury. Sure, we’d like to imagine that all that EPS foam/EPP foam/air pads really do reduce injury–it certainly does in bike helmets–but we don’t know for sure because the government hasn’t specified a way to measure its effectiveness in carseats. So this all points back to having a correctly fitting carseat.
