The easiest way to improve the multiple car seats in a row situation, or even to make a back seat more comfortable for people sitting next to them, is to invest in slender car booster seats.

Booster Seats

Many chairs out there prioritize a small width that doesn’t sacrifice anything in safety, which is most important.

In addition to their narrow width, some of the best seats even improved safety and had added benefits that promote the longevity of the seat and children’s comfort while sitting in it.

We will focus on slender very narrow car seats to help you sort through the options so you know if a high-back booster, a backless booster, or a 2-in-1 booster is the best for you.

The narrowest option tends to be a backless booster, but while your child still needs to be in a high-back version, there are options.

When choosing the best and narrowest car booster seats, there are a few factors to consider.


Narrow Seat Width

When you’re looking for a small booster seat, the first thing you’ll probably think to check is the chair’s width, and you’re right to do so. A typical booster chai width is between 17 and 25 inches wide, so opting for boosters that fall approximately between 15 and 20 inches will guarantee that you’ve chosen one of the narrowest options out there.

This measurement is usually taken at the widest point on the base of a backless booster, but if you’re dealing with boosters that have a high back, double-check to make sure that no area on the back is wider than the widest point on the base, including in the headrests.


Convertibility Of Seats

When a booster seat boasts that it is a 2-in-1 seat or it is convertible, that usually means that as your child grows, the seat will transition from a booster with a high back to a backless booster. Not all boosters do this, but many have this capability, which makes the booster seat last much longer.

That said, sometimes the 2-in-1 seats are not always the narrowest because they have extra parts built in to complement both seats. Widest convertible car seat is great because you can have a booster car seat and an infant seat all at your disposal. Plus, convertible seats can be changed once the child gets older.  You can even turn a convertible seat from a car seat for a child to a booster seat.

There are slender booster seat options too that come out of convertible seats, so consider this, since you can get a slender booster seat that fits easily in the car from a convertible option.

Plus, a convertible seat usually fits most cars, and you can change it from a car seat for a small kid to a seat for an older kid without too much issue.

When looking for a perfect car seat, consider a convertible car, so you’re saving money and can fit it in most cars.  A convertible seat also can be used for up to 100 pounds in most cases, and when you use a convertible seat, you can adjust the car seat to fit older children, which is pretty great too.

Armrest Placement For Narrowed Car Seats

The narrowest boosters often omit or incorporate thin, flexible armrests to save space.

This can sometimes be beneficial because one of the biggest safety mistakes people make with a booster seat is buckling the child in with the vehicle’s seat belts over the top of the armrests, so the belt rests on their stomach instead of along the child’s lap.

Sometimes, these narrow boosters without armrests can be safer for children because they promote correct buckling. Some of these might not have cup holders on them because adding cup holders to a small booster seat adds width. Usually, with a small booster seat or an infant car seat, they are on the side, so if you want to use them, you simply put them down. most booster seats have armrests that are easy to put down, and with a booster seat, you can still have room after adding three of them to your car.


Seat Buckle Accessibility

If you’re trying to cram three boosters into one row of a car, then almost inevitably, one of the boosters will cover up when you need to buckle the child. Although you can purchase extensions to help with this problem, one great way to avoid it altogether is to invest in a booster seat that has some sort of built-in access to the buckle, usually in the form of a hole to access it.

Usually, it’s easy to use a seat belt with a car seat, but some struggle if the car seat or the booster car seat is large.  With a rear facing mode car seat, usually, you don’t have to buckle it each time, which can help some parents since an infant seat just involves a 3-point harness and buckling it.

But, one thing to consider, especially with a booster car seat, since with a booster car seat, you’re having them buckle it themselves, is where the seat belt sits.  Rear seat isn’t as much of an issue, nor is it with an infant car seat and a toddler seat. But once you start looking at booster car options, you should look at where the belt positioning booster mode will fit.

One way to check to see if your car seat or booster car seat will fit is to measure your car.  Usually, a booster seat fits three in a row so you can take the total width and divide it by three. That way, you can look for popular infant car seats that size or smaller. A small booster seat usually can be around the size, or a bit smaller.

Some booster seat options might need a bit more room to buckle, and if you notice that your booster seat is a struggle to get the seat belt into, you might want to consider a car seat that is a little easier

Choosing one of those boosters can maximize your space, so you don’t have to fumble around seats to get your children buckled and even make it so children learn how to buckle themselves quicker.

Child Comfort With Narrowed Car Seat

Your child might end up sending a lot of time in their booster seat, so, although safety is your top priority, you’ll also likely want to choose a booster seat they will be comfortable in. Some come with additional padding to ensure maximum comfort. While a booster seat might not seem like the most comfortable seat in the world, it actually can be very comfortable. Some slender booster seat options are not the best for long journeys.  If you can, maybe take your child to the store, try some booster seats, and see if they like them.  From there, you can trim down the car seat you should consider and choose the best booster option.

To find the best seats on the market and Diono Car Seats reviews, we recommend searching on Amazon. That way, you can see whether the seats on the market will work for your child and what parents have to say about it.  Some may say the high-back boosters aren’t as comfy; some might say that it’s good.  You might also want to look at the specifications on this high-back booster seat since it will tell you whether or not it gives the child enough room.

Some high-back booster seats are comfy, while other high-back booster seats aren’t good for long journeys.  Some are 4 inches wide or more, which means that this high-back booster will work for the long journey, but if the material is less, it might be a bit cumbersome. Overall, you should try these out and consider the car seat options you can get.

Talk to your child about which kind of car seat they’ve liked the most in the past,

and they might be able to give you some clues about what you can buy in the future.
