What Is The Best Narrow Booster Seat?

Picking out the right car seat for your child is very important. First and foremost, having the correct car seat for your child’s age, height and weight can help ensure their safety in the car. But, once you know which kind of car seat your child needs, there are also many different variations of the same seat.

Deciding between different variations of the same style of seat, from an infant seat to a backless booster can also save you some sanity and give you piece of mind. Although any good car seat will keep your child safe and secure, the best car seat will do that and more.

For example, some seats are designed to help promote proper buckling technique, and some provide easier access to your child’s buckle than others. On the other hand, certain seats are more comfortable, with features like flexible sides, armrests and padding, which might help keep meltdowns in the car to a minimum.

When it comes to choosing a booster seat, there is one more feature that can become especially important: the seat’s width. Since children continue to use a booster seat for many more years than any other kind of car seat, it’s very important that a booster seat be narrow in order to fit multiple seats in a row and allow for other passengers to ride more comfortably.

So, in order to pick out a booster seat that meets all of those needs, you’ll need to consider which features and elements you want the car seat to have. We suggest considering the following aspects:

As a general rule, any booster seat that is narrower than about 18-21 inches is relatively narrow, since most boosters vary in width (at their widest points) from about 15-20 inches, although most high back boosters are wider than boosters without a back.

Thus, if you read that a booster seat is 17 inches wide, then you can be sure that you’re getting a narrow seat. Although you may be tempted to just choose the narrowest booster seat you can find, it is a good idea to take into consideration a few other feature that can make your car rides a lot easier and even a little safer.


Some car seats are “combination seats,” meaning that they can be converted from a high back booster to a booster without a back. These seats have more longevity than other seats because of that convertibility, which can mean that your money goes much further. Combination seats are also no less safe than other seats, as long as they are correctly installed.

Some parents complain that while a combination booster seat is a good choice for a high back booster, they tend not to be the narrowest boosters without backs because they originally had to accommodate the back, so you should also keep that in mind when deciding if this kind of seat is right for you.

Although safety is parents’ number one concern when it comes to seats in the car, many children spend a significant amount of time in the car and having a comfortable seat to sit in can make a big difference in terms of a child’s behavior.

Opting for seats with armrests, headrests and cupholders can help keep your child under control, which can also be a plus for their safety, since the main role of car seats is to keep your child correctly positioned.

Seat Belt Accessibility

One of the biggest battles most parents have in the car is getting their child buckled correctly, and the first attack on that front is getting to the buckle. Most parents know that a seat buckle can get easily drowned under all the plastic of a car seat, but some make accessing it much easier than others.

Some seats also are designed to promote proper buckling technique: that, is the buckle sitting snugly on your child’s lap, which can also be another feature that promotes your child’s safety.

Are high back boosters safer than a backless booster?

In general, how safe any kind of car seat is for a child depends on how the seatbelt fits them. The goal of a high back booster is to ensure that the seat belt hits your child’s shoulder and chest in the right place. 

If it hits the child correctly in a backless booster, then it’s not necessarily inherently any less safe than a high back booster, but it can provide less padding and might not keep your child in the correct position as they squirm and sleep, which can make a high back booster safer.
