What to consider when choosing the best car seats for a small car


While looking for a car seat for a compact car, Schroeder says, “Some infant car seats are more compact than others (the Chicco KeyFit 30 comes to mind) and may fit better in smaller vehicles.” There are even models specifically designed to fit (hopefully) three in a row. For your convenience, below are the dimensions of each car seat so you can quickly measure what will fit in the back seat of your car.

But it’s not just a matter of choosing the most compact car seat – the size and shape of the car seat must fit well with your car and any existing seats. “The fit of the vehicle is one of the most crucial parameters that contribute to good crash performance for a car seat,” explains Dilts.

Safe installation

As a father of three, Dilts knows the battle is real when it comes to selecting and install a car seat. “It can be challenging to install a car seat up close,” he says. When it comes to proper installation in a small car, both Dilts and Schroeder warned of the same problem. Schroeder explained that in smaller vehicles, it’s critical to “watch out for rear-facing car seats” [are touching] the rear car seat […] the backrest of the driver or passenger seat.”

Dilts underlines: “This practice is dangerous and can affect the way the child car seat will behave in an accident.” He says you should be able to slide a piece of paper through the space between the front seat and the car seat.

He points out that a driver who needs more legroom “can limit installation options to the center or passenger side of the rear seat.” In this scenario, he recommends “choosing a car seat that offers plenty of reclining options.” [which] increases your chances of finding a good match.”

While there is no magic infant or toddler car seat that will fit perfectly in every vehicle (or stay miraculously clean), “the safest car seat is the one that fits your child, fits your vehicle, fits your budget, and that you use correctly every time.” can use,” says Schröder.

After 3 different HBB’s, this Peg Flex is the holy grail. Here’s why: It doesn’t have armrests, so your kid can do the buckle themselves. […] The Flex has a narrower footprint than others because it has no armrests. Need 3 kids to ride? Do you need 2 to sit next to each other? You are golden. You can park the Flex next to different seats without any problems. […] The Flex can be adjusted in 4 directions, so your picky big child can decide exactly how the seat is best for him or her. […] This chair is no more expensive than its competitors, but it looks and feels like it should be. […]”
