4. Diono Radian 3RXT 4-in-1 Convertible Car Seat

Best Narrow Convertible Car Seat

Diono Radian has been consistently creating excellent car seats, which is why we’re on the third version of this convertible seat.

This slim fit convertible seat offers a 4-in-1 performance, making it an excellent choice for parents who like to get the most out of everything. 

The Diono Radian 3RXT offers 4 ways to travel: newborn rear-facing, rear-facing, forward-facing with harness, and high-back booster.

This means the seat can be used from 5lbs to 120lbs, providing an incredible 10 years of use. 

With this incredible capacity, you might expect the Diono Radian 3RXT to be a large seat. However, it’s actually incredibly narrow, with a width of just 17 inches. For expanding families, the Diono Radian will fit easily alongside other car seats. 

For newborns, the Diono Radian is safe and comfortable, with a travel wedge that can be used to create a lie-flat position.

When your little one has grown, this wedge can be removed, and the infant positioning liner provides the support you need.

A contoured Ergoboost seat and dual-density padding are super comfortable for kids, while the deep rigid shell and EPS energy-absorbing foam add protection and security. 

Parents will love the small profile of the Chicco MyFit, which allows the car seat to be maneuvered easily. We also think any parent will appreciate the zip-off backrest and seat cushions, which makes cleaning easier than ever!

Buyer’s Guide on the best slim car seat

If you’ve ever tried fitting three car seats in a row, then you’ll understand why some parents are interested in as narrow a design as possible.

Car seats can be bulky and inflexible, and once you have two secured, you might find there’s no room for a third. 

But narrow car seats appeal to more than just parents with multiple children. Narrow car seats can fit into more cars, are easier to carry, and better to travel with. And they do all this without sacrificing the comfort of your child.

So, there are many reasons why you might think about buying a narrow car seat. However, it’s important that you consider more than just the width!

We’ve put together a buyer’s guide so you can better understand how to choose a narrow car seat. Let’s take a look.

Width

If it’s a narrow car seat you’re after, then you have to consider the dimensions first. Look for a width between 16 and 17 inches. Any wider than 17 inches, and you will probably struggle to fit all three seats in the back of the car.

Make sure the width refers to the widest part of the car seat, including the handle. 

Width isn’t the only dimension to think about, although if you’re looking to fit 3 car seats side-by-side, it’s the most important one.

The length is also worth noting, as some narrow car seats can be long, and struggle to fit into front and back seats. It’s also important to consider all dimensions if you’re purchasing a narrow car seat for traveling.

A long or tall car seat will be difficult to travel with, even if it is slim.

Weight And Height Limit

Narrow car seats are available for a wide age range, but it’s important to check the exact specifications of each model. Some car seats will only be useful for a couple of months, while some can be used for years.

Instead of age range, most car seats will have a height and weight limit.

Overall Weight

Whether you want a narrow car seat to accommodate multiple children, or for increased portability, it’s important to consider the overall weight of the car seat. Narrow car seats tend to be lighter than average, as they use a slim build.

However, this isn’t always the case. If portability is a key concern to you, then make sure you know the weight of the car seat.

Safety

Whatever kind of car seat you’re after, safety is a crucial concern. Car seats should be rigorously safety tested before being sold, to ensure they’re safe for use. Check for the safety certification of any car seat before you buy.

Comfort

A narrow car seat shouldn’t sacrifice comfort just to reduce space. Padded cushions must be used to support the child, and to keep them comfortable in the car.

Look for designs with molded and movable padding, which will adapt to your growing child.

The fabric used is also a key concern. Fabric should be soft and breathable. This prevents the car seat from becoming too warm, which will be uncomfortable. 

One final aspect of comfort is recline. A good car seat will come with recline and adjustments that can be used to alter the angle of the seat to better suit the needs of each individual.

Installation

Trying to fit three car seats into one car? Then you probably don’t want a seat that’s difficult to install. It should be easy to not only install the seat, but to install it securely.

Some car seats will use the LATCH system, while others will attach to the seatbelt, and some use a combination of various installations. 

A helpful feature is an installation indicator. This will tell you when the seat is safely in place, so you know you’ve got it right. 

Stroller Compatible

If you want a car seat for a younger baby that can be used with a stroller, then you need to check that it’s compatible.

This can be a tricky feature to understand. Some car seats are compatible with multiple strollers, and can be used with a wide range of brands.

Other car seats will only be compatible with a single brand, and won’t fit into any other stroller frame. 

Cleaning

With three kids in the back of one car, you can expect a fair amount of mess! It’s pretty much inevitable.

So, it’s important to choose a car seat that can be easily cleaned. Look for wipe-clean materials, so you can quickly deal with small spills as they occur. Worried about a bigger mess?

Many car seats come with removable fabric coverings that can be machine washed and dry quickly. These are excellent if you know your kids can’t go on a long journey without a major stain!

FAQs on A narrow infant car seat

Can You Fit Three Car Seats In The Backseat?

Potentially, you can fit three car seats in one backseat, but you have to choose the right car seats! If you want three car seats to fit, they should be 17 inches wide at most. Any wider than this, and they just won’t fit.
You also need to check how the car seats are installed, and whether they need the LATCH system, or can fit into the seatbelt. This is particularly important with the middle seat, which might not have much room. 
And even three narrow car seats might not fit, if you have a particularly small car. Make sure you understand the dimensions of your car when buying multiple car seats.

Are Narrow Car Seats Safe?

Yes, narrow car seats are perfectly safe! Safety should never be sacrificed to reduce the width. Car seats must be rigorously safety tested before being sold, no matter the size.
Because of this, a narrow car seat is just as safe as a bigger car seat. Be sure to check the safety credentials of the car seat before buying, particularly if you’re choosing a car seat from a little known brand.

How To Choose The Right Narrow Car Seat?

Width is obviously the key consideration when choosing a narrow car seat. A narrow car seat is typically 17 inches wide or less.
Other important features to consider are safety, ease of installation, comfort, and the height and weight limit of the car seat. Don’t just focus on the width, or you might find your car seat doesn’t meet your needs.
If portability is important to you, make sure to consider the length and height of the car seat, as well as its overall weight.

Final Thoughts on the best narrow infant car seat

Fitting three car seats into one car is never going to be easy, but with the right narrow car seat, you can safely get three kids side-by-side.

And there are plenty of options for all children, from newborns, to toddlers, to older kids, so you can make the right choice for your family! We hope this guide has helped you find the perfect narrow car seat for you.
