Best Narrow Car Seats: Booster,Convertible and Infant

by April Driver |

For families with three or more children or families that prefer a smaller vehicle, narrow car seats and narrow booster seats are essential to fit everyone in the vehicle. However, searching through all the products in the market to find the right narrow seats may be a challenge. Consider the maximum width, price, safety ratings and user ratings when selecting a narrow car seat or narrow booster seat.

The good news is that some of the narrowest car seats are also among the top convertible car seats.

Narrow Car Seats and Booster Seats

1. Clek Foonf Rigid Latch Convertible Car Seat

If budget is not a concern, the Clek Foonf Convertible Car Seat is an awesome choice. This narrow car seat is definitely an investment. However, it is only 17 inches wide and has a sleek modern design. The manufacturer also says it fits difficult seating positions. Think about when you need one rear-facing seat and two forward-facing seats.

This seat also boasts GREENGUARD certification meaning it is made without harmful chemicals. The Clek Foonf is a great option for families searching for a narrow car seat.

2. Diono Radian RXT Convertible Car Seat

The Diono Radian RXT Convertible car seat is also only 17 inches wide. It’s at a lower price point than the pricer Clek Foonf but otherwise it compares similarly.  The manufacturer says this seat is designed to work well in the middle seat around other child safety seats. This seat is also GREENGUARD certified and rates well on safety. The main difference other than price between this and the Clek Foonf is the modern design style of the Clek Foonf.

Things To Consider

Buying child safety seats can quickly become overwhelming. The market has such a large selection that finding the perfect seat takes time and research. However, once you understand your needs, you can begin your search.

Before you buy, consider how the car seats interact with each other. While the seats you like may be narrow, make sure they work side-by-side to fit your needs. For example, does a rear-facing infant seat fit between to two front-facing convertible seats? The seats must all work well together for the seats to fit.

Another consideration is whether your booster seat child can reach the seatbelt buckle to latch it. Does the other child safety seats block the seat belt? If so, you may need to opt for a booster seat that includes a harness.

Also, always consider your budget when purchasing a narrow car seat or narrow booster seat. The lowest priced item may not be the best financial choice. Read the reviews to ensure good quality. You don’t want to have to buy a new seat every year because it gets easily damaged. Buy a quality car seat from the start that will last you until it expires.

Car seat width is a big concern for large families and families with smaller vehicles. Thankfully, it is now easy to find options for every budget.

As always, safety is a top priority when choosing a car seat. Read up on the latest safety guidelines before you shop. Our Car Seat Safety article will answer all your car seat safety questions.
