Buying Guide: How to Purchase a 3-in-1 Car Seat

No-rethread Harness

A lot of harnesses require manual rethreading through holes on the back of the car seat to change the height. That is always an annoying nuisance. If you’re looking for comfort and easy adjustment options that make your life easier, then aim to find a car seat that does not require rethreading. It is highly recommended to get a car seat without rethreading required.

Hence, aim to find a car seat that does not require rethreading. While that might be a little more expensive than the traditional car seats, a harness that can adjust up and down with a click of a button will make your life easier.

Weight Limit

Generally, placing your baby in the rear-facing position is the recommended position. That’s because it reduces any impact absorption in that position if an accident occurs. Hence, if you plan to place your baby in that position, make sure that the car seat accommodates high weights in that position.

Generally speaking, if you’re aiming to purchase a 3-in-1 car seat, then you probably want it to last you and your child for a few years. That’s why we advise you to find a car seat that can grow with your child and accommodate different heights and weights as they grow.

Installation System

The best car seat installation system out there is the LATCH system which was introduced in 2002. It has been designed to make installation easier and faster for all parents. When using the LATCH system, you will need to use the seat belt already in your vehicle.

However, keep in mind that the LATCH system can only be used for kids that weigh under 40 pounds. After that, you will need to use the vehicle’s seat belts to secure the car seat. That’s why we recommend you find the most comfortable installation system that works for you and your specific car.

FAA Approved for Air Travel

The FAA is the Federal Aviation Administration. They individually approve car seats that are safe to travel on airplanes. This is a vital feature because this makes your life much easier, especially if you’re considering traveling around with your little ones.

If you’re wondering if your car seat is FAA approved, you will find a sticker somewhere on the back, side, or underneath the car seat. Hence, if you are planning a jet-related trip with your baby, then make sure you keep them secure throughout the journey with an FAA-approved car seat.

Steel-reinforced Frames

For rigidity and stability, steel-reinforced frames are the way to go. Most 3-in-1 car seats now use this feature, and it has been proven to increase the frame’s structural rigidity. This also helps in the case of the event of a car accident.

Energy-absorbing Foam

You should look for the energy-absorbing foam to minimize any impact on your baby. That impact includes any sudden movement from your child or an accident. The two most common types are EPP and EPS, which are exceptional and reduce the energy of the impact on your baby.

The foam is placed in the seat’s shell, typically found on the sides, bottom, and back. As safety comes first in every scenario related to your baby, we recommend finding energy-absorbing foam car seats.

Crash Testing Performance

The federal government is responsible for conducting these tests on car seats, but they do not publish the results. They do not share their findings as they do not want to create bias around which car seats are safer than others, as they do not want to openly side with specific companies.

However, other organizations like Consumer Reports and Insurance Institute for Highway Safety conduct these performance crash tests available to the public. This is a great feature to look for to ensure your baby is safe and sound, even in the unwanted event of an accident.

Adjustability

The car seat should be comfortable and easily adjustable, providing the versatility that supports a growing baby. Hence, we recommend finding a wide range of adjustments in a car seat. Look for car seats that allow you to adjust the headrest, harness, and crotch buckle.

Generally, we prefer headrests and harnesses with 5 or more different height positions and a crotch buckle with 2 or more adjustment options. Reclination is also a notable feature to consider. Look for something with 5 or more reclination positions to provide comfort for your baby.

Side Impact Protection

Always put the safety and security of your child first. That’s why a car seat with great features for side impact protection should be considered. This feature includes having a range in thickness and body coverage of the side cushioning.

However, the more the side impact protection, the bulkier and less space for your baby. Hence, do not look for extreme protection as that will also pose to be more on the expensive side.

Size and Weight

No one wants a car seat that is too heavy, right? Do you really want to struggle with getting it in and out of the car every time you want to detach it? Hence, look for something that has excellent quality but is not too heavy for you to carry along with your baby in it.

Moreover, while bulkier car seats usually mean more protection, we recommend finding something slimmer. That way, it would comfortably fit in your back seat. You would still want space for other kids to sit there or simply a storage room for all your baby stuff.

Comfort

Last but not least, consider the comfort the car seat provides for your baby. This usually is extra padding around the insides of the car seat and breathable material. That will help your kid stay safe and sound inside and allow them to nap with a breeze.

Moreover, we recommend finding a car seat that fully reclines. That honestly can be a life-saver for parents who drive around for hours hoping that their baby falls asleep. Trust us, the perfect way to go around that is with a car seat that reclines all the way back.

Conclusion: Best 3-in-1 Car Seats of 2022

If you’re still struggling with which 3-in-1 car seat to purchase, then there are two things you should always keep in mind. Always have a budget in mind, and then keep the safety of your child in mind at all times.

It never is easy purchasing a car seat, but we always recommend investing in a higher quality one that will last your kid through different points of their life. Also, if you’re planning on having a bigger family, then make sure the car seat can last you for longer so you can use it for other babies too.

Beyond those features, ensure that the harness has numerous different adjustment options to fit your child, and that the car seat itself is comfortable. Full reclination is always a plus, which will help your child sleep soundlessly back there without any discomfort.
