8 Best Narrow Car Seats

This article may contain affiliate links. For more information, please see our Disclosure Policy.

While there are plenty of car seat options that can make your kid’s car ride more enjoyable, narrow car seats remain a priority for parents with a compact car.

They make it possible to fit three car seats across the rear seat of your vehicle if you need to fit multiple kids in the back.

You may also want a narrow car seat so you can leave enough room for adults to ride in your car as well.

Whatever the reason that has you looking for a narrow car seat, I can assure you that you won’t go wrong by picking one. These car seats have all been put through rigorous safety tests before they are put on the market.

We have done most of the legwork and come up with a list of car seats that are suitable for newborns, toddlers, and even older kids who can use your vehicle’s seat belt. Let’s dive in and help you find the best narrow car seats for your child.

The Graco SlimFit car seat is a great contender when it comes to space-efficient baby seats that deserve a spot in your car.

It sports a 3-in-1 design so you can start using it as a rear-facing seat, then convert it to a forward-facing harness, and finally, a high-back booster seat.

To help you secure it on the rear seat, this car seat is designed with a push-button, InRight latch system. The latch offers an audible click that lets you know you’ve installed it correctly.

Once you secure it, you will appreciate that both the headrest and harness can be adjusted together in one quick motion.

The headrest can be adjusted by up to 10 different heights, so it’s a seat that grows with your child until they are about 57 inches tall. Also, 4 recline positions help to keep your child comfortable whether they are in the rear-facing or forward-facing position.

Another interesting feature is that it’s integrated with two rotatable cup holders. You can push them in to make the car seat up to 10 percent slimmer.

We also love that the seat is crash-tested to ensure that the child will remain protected from all sides in the event of a crash.

Chicco didn’t cut corners when it came to making this unit safe as it has a tough carrier shell that’s lined with energy-absorbing EPS foam.

You can attach it to other Chicco strollers so you can still use it to take your baby out for walks.

5. Diono Radian 3RXT

It’s any parent’s dream to have the ultimate car seat that their child will use until they are ready to seat safely without the extra support. On average, that will be at the 10-year mark. This is why we included this 4-in-1 convertible car seat.

It starts as a rear-facing car seat for a newborn. At this stage, you can rely on the 2-in-1 infant-positioning liner that’s equipped with a wedge to secure your baby in a lie-flat travel position.

The wedge helps to push the baby up to prevent head slumps and keep their airway open.

As your child grows into a toddler, you can remove the wedge so your baby can stay comfortable in the forward-facing booster seat.

Thereafter, the aluminum-reinforced headrest can be adjusted by up to 12 different positions to accommodate a child that’s up to 57 inches tall.

Lastly, you can ditch the harness when your child is tall enough to use your vehicle’s seat belt.

To ensure it remains in good condition as your child grows, this car seat is designed with a sturdy construction made of a reinforced steel core and automotive-grade high-density plastic.

Got a little more room in the budget? The Diono Radian 3QXT has a few more creature comforts without making the seat much bigger.

Product width: 17 in.

Maximum height: 57 in. 

Maximum weight: 120 lbs.

To keep your child from sweating excessively, the car seat is designed with a breathable mesh fabric that offers a cooling effect.

Attaching it firmly to your vehicle’s seat will be a breeze since it comes with color-coded belt paths for easy seat belt routing. The base is equipped with a RightTight System so it locks in place using either the vehicle’s seat belt or a latch strap.

Product width: 17.25 in.
