Table of Contents

Now that you are a parent, the car and drives are no more only yours and your partner’s. You’d often need to drive your babies around, and once you have your second or third baby, you would even need two-three car seats; all of them being narrow enough to fit next to each other. You would perhaps already know that it is illegal to even take your baby out without an infant car seat. Now given this fact, you might have already spent a lot of time looking for the best car seat. This process could get rather confusing and annoying because where does one find a car seat that is narrow enough, comfortable enough, safe enough, does not hurt your fingers while clipping in, and also does not take too long to clip in?

Look no more, Parenthood Bliss does the job for you right here! Before we get to the list, of the best, narrowest, non-convertible infant car seats, let us first establish some basics. An infant car seat, typically, comes in three types; infant convertible car seat, infant non-convertible car seat, and infant booster car seat. While the convertible car seats can be found at about 16-17” wide, the non-convertible and the booster seats are usually and mostly at 17 inches wide.

Here is a quick cheat-sheet to the best narrow car seat(s) for your baby

1. Chicco KeyFit 30 Infant Narrow Best Baby Car Seat

The Chicco infant car seat is not only narrow but it also is hands-down one of the safest, most stylish and functional car seats to speak of. The base of this car seat is at 15” wide and the seat overall is at 16.5” wide. A reliable and versatile car seat, this one can be attached to the base of your car either through the latch system or by the conventional seat belt mechanism. The car seat offers multiple shoulder strap positions, however, for the downside, there is just one crotch buckle position which can be uncomfortable for bigger babies. The adjustable shoulder straps are easy to use and really wide which avoids too much twisting. There also is a lot of space between the canopy and the handle which leaves a lot of space for your hand to comfortably fit in and makes holding/carrying the car seat convenient even when the canopy is up.

Selling at about 200$, the car seat comes in a lot of fun prints, is one of the narrowest on the markets, and can hold babies up to 30 pounds while it, itself, weighs only 15 pounds.

2. Peg Perego Primo Viaggio 4/35 Infant Narrow Best Baby Car Seat

One of the best infant car seats out there and not only on the list, this one measures 17” wide at its widest point. We say “widest” point because this is where the handles can connect to the sides of the seat. The base of this seat is only 14.5” in width. This infant car seat can hold babies up to 35 pounds and 32” tall (when rear-facing)As for the comfort and safety aspects, this one matches up with all the expectations as it has an anti-rebound bar that limits the rotational force if, in an unfortunate case you happen to meet an accident.
It also has a 5-point harness that requires no rethreading and the seat is also adjustable (up and down between 6 positions) and offers a side impact protection. As for one downside in terms of safety, it lacks a steel-reinforced frame that other car seats do.

The padding of this seat is very comfortable, made in high-quality soft jersey cotton fabrics that makes it breathable and is also very premium to look at. Other downsides of the car seat which should be known include: that the canopy of this car seat rubs up against the handle which might squish your fingers a little bit. Also, the harness straps are thin which does not keep them from twisting, unlike the Chicco car seat. Apart from these two points, as mentioned, there is no steel frame which has one compromise on structural rigidity. All in all, though, it is undeniably very well-designed and it is an ultimate piece of craftsmanship and quality-stitching. This non-convertible car seat is priced at 300$.

3. UppaBaby Mesa Infant Narrow Best Baby Car Seat

Another really narrow car seat to speak of, the base of this car seat comes at just 14.5 inches and the entire seat as a whole comes at 17”, even with the handlebar levers sticking out on the sides. A slimline car seat, this one makes installing as many as three car seats possible, even in really small vehicles. A plush, comfortable seat made with premium, high-quality materials, this one can hold babies weighing up to 35 found and 32 inches in height. The seat can be installed by simply clicking it on the base and for a noticeable fact, the adjustable harness of this seat is wide which avoids entanglement; and even the headrest is height-adjustable without the need of rethreading. For some cons, the fabric is arguably not the softest and not the most breathable of what is available on infant seats. The sunshade and the handles also interfere with each other.

Weighing less than 10 pounds, this seat does include latch connectors and is priced at about 300$.

4. Baby Trend Flex Loc Infant Narrow Best Baby Car Seat

Named on several articles that list the best infant seats under 100$, this car seat measures only about 16.5” in width, can hold babies between 5-30 pounds, and is really cool and functional so to say. This car seat comes attached with a carrying handle and unlike other seats that force you to carry them parallel to your body, this one lets you conveniently hold it at various angles. This particular feature really stands out especially for when your baby starts growing in age and starts to become bigger and heavier. Besides, for a car seat that is not exuberantly priced, the fabric of this car seat is rather amazingly comfortable, soft, breathable, and easy-to-clean. The adjustable harness requires no rethreading and the car seat can actually also be very easily installed, by just clicking it on to the base. The up-front shoulder strap can also be tightened or loosened and is strategically positioned by the engineers to ensure an optimal connection with the base.

Some small issues that should ideally be ignored for its really cheap rice point but still need to be mentioned for awareness sake are A) the shoulder straps are rather flimsy and not very well structured which cause them to twist and turn while you out the baby in B) The handlebar can be annoying as it is not so easy to adjust and requires some serious, hard pressing of buttons C) The front recline does not function as smoothly as one would expect it to D) Some parents did review the crotch buckle to be ‘difficult’ to understand

5. Cybex Aton 2 Infant Narrow Best Baby Car Seat

An extremely-extremely light-in-weight car seat, this Cybex seat is also ultra-portable, slim, made in premium quality of materials, is really slim and boasts of European comfort and styling. The seat weighs a mere 8.8 pounds and it measures 17.5 inches in width when measured with the handles. As for its safety features, this car seat is majorly impressive as it is equipped with a load leg feature that can reduce rotational forces in the event of a car crash along with offering side impact protection and a latching capability. The seat can hold babies in the weight range of 4 to 35 pounds. As for its price, it is priced at 300$ but you also need to pay an extra 160$for the base alone. This could be argued as a rather unfair and unreasonable price by some because the canopy of this car seat is not all that great in terms of size and getting the baby in and off is not the most convenient in this seat. Though great in all other aspects, the price and this tiny downside can have one not purchase the seat – and if you are one of those parents, we would recommend Chicco as a great alternative by virtue of similar features and size.

Final Thoughts-

According to studies done by Pediatrics, the infant car seat for a newborn to the age of 3 must have their car seats installed in the center rear seat. This keeps them about 43% safer compared to them sitting in the back of the car on either side. However, studies have also shown that about 41% of parents install their infant baby car seat right beside their seat. That is the rear passenger side, it helps them have a better reach to their kids. But, make sure this could also distract you. So, we feel the center is a better option, concerning their safety, but, you could install the infant car seat as to your preference, just make sure it's safely placed.

4. Could I turn the infant car seat around? And, when can I do so ?

Cases with children that are between the age of 1 and 2, can have their car seat facing the back of the car. This keeps them 5 times safer compared to any other position. Therefore, most infant car seats are convertible and safe for kids to face in the direction of the rear, and work best for kids that weigh up to 35-45 pounds. So, you don’t need to turn the infant forward just yet, this could hurt their back and can also risk a spinal injury.
