Now that we’ve gone over the most important things to think about before making that purchase let’s have a look at what the best out there the market has to offer to keep your baby safe and sound.

Evenflo Triumph LX Convertible Car Seat

A product by Evenflo, the Triumph LX car seat, comes with a design to provide great comfort as well as safety to your baby.

It can be installed in the rear-facing position holding an infant weighing from 5 to 40 pounds with a height range of 19 to 37 inches. In a forward-facing position, it can hold a baby weighing between 22 and 65 pounds with a height of 28 to 50 inches. So there will be plenty of room for your baby to grow heavier and taller.

It comes with a LATCH system that makes for quick and easy installation and removal of the seat. It shouldn’t be too much trouble moving the seat from one car to another if necessary. In terms of convertible car seats, this product is fairly lightweight and compact, so it is fit for use in many different vehicle types and sizes. 

No re-threading is required to make height adjustments, as it comes with a five-point slide harness technology and an easy buckle release. Additionally, a side knob comes with the car seat, which you can use to adjust the tightness of the harness.

Extra protection and comfort are provided through the product’s e3 Side Impact protection system. On a more general scale, the Triumph LX passes safety standards for child safety in both the US and Canada.

It doesn’t stop there. The car seat comes with a plush pillow for your baby’s head and can be reclined to different positions when forward-facing. This makes it ideal for your baby’s comfort during long car trips. Two cup holders ensure your baby can reach for their drinks and snacks without disturbing you while you drive.

Lastly, the seat is easy to clean. The car seat pad can be machine-washed in a delicate, cold-water cycle. Both the harness and base can be cleaned using mild soap and water and dried by cloth later. Believe me, having a car seat that is easy to clean is more important than you might think. You never know when your little one will make a mess.


  • Easy to install and move from car to car
  • No re-threading is required to adjust the shoulder straps
  • Compact size and lightweight
  • Comfortable for long car trips where the baby needs to sleep
  • Two cup holders for your child to keep their drinks


  • Straps can be tough to clean as they can’t be completely removed

Safety 1st Continuum 3-in-1 Car Seat

Designed by Safety 1st, the Continuum car seat is made to last with your family through the three different stages: rear-facing, forward-facing, and belt-positioning.

For the rear-facing position, the seat is able to hold babies with weights ranging from 5 to 40 pounds. When changed to a forward-facing position, that range goes up between 22 and 50 pounds. When your child is finally ready to transition to using the vehicle’s seat belt, the harness is removed, and the weight limit goes up to 80 pounds.

The harness system that comes with this car seat is pretty neat. When it is rear- and forward-faced, the holders keep the harness in an open position, which saves you the effort from having to fish for the clips. Additionally, the headrest, along with the harness, can both be simultaneously adjusted in one simple step. When your child no longer needs the harness, the headrest remains easily adjustable on its own.

The product exceeds federal safety standards. It also provides additional comfort and some protection via extra pads around the head area and a grow-with-baby pillow, which can be easily removed when no longer needed. Additionally, it comes with one cup holder where your child can put their favorite drink.

Cleaning the Continuum is a very simple job. It doesn’t require any disassembly of the car seat, nor its removal. The padding is attached via snaps that only need to be triggered for it to be removed and then put into the washing machine. Similarly, the cup holder can be removed.

The car seat has three different reclining positions, which make it fit more easily into cars. Its compact size makes it take less space in the back seat. Consequently, this provides extra room when in the rear-facing position for the adult passengers.


  • Can still be used when your child grows beyond the harness
  • More legroom makes for a more comfortable ride for the adults in front
  • Both the cup holder and the padding are easily removable and washable
  • No re-threading required to adjust the harness
  • Headrest is adjustable and features side padding for more comfort


  • The lever that adjusts the seat recline can rattle when the seat is empty
  • The headrest can also slightly rattle when not in use

Diono Radian 3RXT All-in-One Convertible Car Seat

Engineered to provide enough protection and more, the Radian 3RXT car seat does not shy from going all out when it comes to protecting your child.

It’s constructed using a steel alloy frame, and its side walls are reinforced with aluminum. This is in addition to the hard energy-absorbing as well as soft memory foam, which covers almost all of the seat, including the seat bottom. The harness also comes with pads for the shoulder, chest, and crotch areas.

It can remain being used in the rear-facing position until your baby reaches a weight of 45 pounds. After that, the seat continues keeping the child safe in its forward-facing position until they reach a weight of 65 pounds. 

After your child is using the car’s own seat belt, the seat remains usable as a booster seat, holding weights of up to 120 pounds. As such, it can be used for an extended period of time, as long as 10 years.

The Radian 3RXT also comes with a sleek design that gives it a compact fit. In most medium-sized cars, you’ll be able to fit the car seat and still have room for two more to be installed. With the ability of having three car seats installed in your car, there’s more room for larger families of small kids to share the same ride.

Installing the car seat is made easier since its LATCH system makes an audible clicking sound when it’s properly secured in place. Despite its heavier weight, the seat is actually still quite portable since it can be folded and is certified for use in aircraft. So transporting this comes as no problem at all if you’re one passionate enough to travel a lot.


  • Steel alloy core makes it very sturdy and capable of handling impact
  • The ability to fold the seat makes it very friendly for transport
  • Sleek design allows you to fit three across your car’s rear seat
  • Can be used until the child reaches a weight of 120 pounds

Evenflo Sonus Convertible Car Seat

Another versatile model by Evenflo, the Sonus car seat stands out as an item that offers a balanced fit for both your child and your car.

In a rear-facing position, it’s able to provide a comfortable seat for your toddler until they reach 40 pounds in weight or 40 inches in height. After that, it can continue being useful in the forward-facing position until your child reaches 50 pounds in weight or 50 inches in height. 

The Sonus is lightweight, at just over 11 pounds, and comes with a compact design that allows you to fit three across the backseat in most medium-sized vehicles. This doesn’t mean it’s narrow, though—the seat’s base has a bit more width in it; hence it makes for a suitable fit for a range of children. Traveling around the world with this seat is also possible since it’s approved for use on airplanes.

In addition to the product’s exceeding of the federal safety standards, it’s also tested for rollovers, which they claim is new to the industry, and side impact according to company-made standards.

You child won’t have any trouble dealing with different temperatures and climates while they’re using the seat. The product comes with a built-in air circulation system and vents that provide good aeration to your child at all times.

Moreover, it also features adjustable shoulder straps that have five different positions. That way you’ll always be certain they properly fit your child. The harness tension can be easily accessed and adjusted as well. 

Additionally, there are little pockets where you can put the buckles when you’re not using the seat to prevent them from getting hot from being exposed to the sun inside your car. This is a great idea, I’ve almost burned my little ones so many times because of this!

What to Consider Before Getting a New Car Seat

Before you set out to buy that new convertible car seat for your baby, there are many things you should consider. This isn’t just any kind of purchase you’re making—it will probably be one of the most thoughtful and possibly expensive decisions you’ll make. In the end, it will be worth it, because the safety of your baby comes first.

Check Your Vehicle

The first thing you should do is to look at your vehicle and decide whether you’re going to use the seat belt or the LATCH (Lower Anchors and Tethers for Children) system to install and secure your baby car seat.

Look at your back seat and see where your LATCH attachments are. Also, don’t forget to measure your back seat and see how much room you have in there. Determine whether it will be able to fit a convertible car seat with a large base or whether you’d need something narrower instead. 

Height and Weight Limit

Convertible car seats are designed to handle a range of weights, as well as heights. It’s important to make sure that your car seat has enough room for your tall baby as well as the capability to handle the baby’s growing weight. 

Convertible car seats can be adjusted to the rear-facing or forward-facing positions. You should determine whether your toddler’s height can be accommodated by a rear-facing seat position since it’s safer from birth until two to four years. 

With time, your little one’s height will grow to a point where the forward-facing position becomes inevitable to provide more room for your baby’s legs. Depending on the seat’s height and weight limit, this will determine how many years you can use it.

Safety Standards

A core attribute that you should always pay heed to. This is what ultimately determines how capable the convertible car seat is for protecting the baby. 

Ensure that the seat is certified and has passed crash tests, side and rear impact tests, and more such as extreme temperatures and rollovers. The product should be certified by recognized bodies and come with a range of safety standards.


It’s important to be aware of what your car seat is constructed from. Many seats come in a hard plastic outer shell with an inner dense, hard foam padding that’s capable of absorbing energy. Some seats employ metal frame components that add to its strength and durability, and possibly even increase its safety performance.

Additionally, comfort is also an important factor in a car seat’s construction. This is achieved mainly by including an additional layer of soft foam padding topped with fabric to give the seat’s final appearance. The design also helps adjust the baby’s position while they’re seated. 

Ease of Installation and Adjustment

It’s always handy to have directions that aid you in properly installing your seat, whether via seat belts, the LATCH system, or both of them. These instructions will also tell you what not to do to avoid any mistakes in the installation.

Car seats that come with level indicators are also very useful in aiding you to correctly put the seat. Always make sure that the marked level line is parallel to the ground. For others that use a rolling ball or a moving bubble, ensure that the ball or bubble is positioned within the markings on the indicator.

Some convertible car seats don’t require re-threading when it comes to adjusting the shoulder height of the straps. These are easier to adjust compared to ones that require re-threading, which involves disassembly, and later reassembly. 

Convertible car seats are much heavier and cumbersome compared to infant car seats as they last until toddlerhood and beyond, so you don’t want to be taking them out of the car very often. That said, ease of installation is an important consideration even if it only comes up occasionally.

Not a Tall Order

Now that you’ve taken this ride with us through all your options as to what the best convertible car seat is for your tall baby, let’s see which one wins the jackpot.

The Graco Extend2Fit emerges as our winner, as it encompasses pretty much all the important attributes and features we discussed earlier.

It’s easily installed and moved between cars. It meets and exceeds all the child safety standards in both the US and Canada, providing great safety. It’s easily adjustable, also also able to remain in rear facing mode for an extended time if desired. That checks all the boxes in our book.
