Best Britax Convertible Car Seats

At this point in time, if a product doesn’t have at least two distinct uses, it’s practically vintage. Enter the convertible car seat!

This car seat type is the one for you if you’d rather bypass the infant car seat entirely. Convertible car seats can be both rear-facing and forward-facing, making them a buy-once-and-forget-it purchase. Consider this: if you ask for a convertible car seat as a baby shower gift, you won’t ever have to stress about buying a car seat yourself!

With that in mind, does a Britax convertible car seat deserve a spot on your baby shower registry? Big time yes. Britax car seats are some of the best you can buy, in terms of durability, safety, and style. Plus, hello! Only one car seat for life!

Britax One4Life ClickTight All-In-One Car Seat

Britax One4Life ClickTight All-In-One Car Seat – 10 Years of Use – Infant, Convertible, Booster – 5 to 120 Pounds + Cool Flow Ventilating Fabric, Cool Flow Teal [Amazon Exclusive]

The Britax One4Life ClickTight All-In-One Car Seat is the only car seat you’ll ever need!

Here’s the reality about car seats: you typically have to buy at least two of them; in some cases, three of them! You can start with an infant car seat and then transition, or you can start with a convertible car seat. Either way, you’ll eventually need a booster.

That is how it traditionally went. Britax took that notion and flipped it on its head. This is one car seat and it’s the only one your need for your child. Ever. It covers all the way from newborn to a mind-blowing 120 pounds! It rear-faces and it forward faces and it boosts!

Surely, if it’s the only car seat you’ll be purchasing, you want to make sure it is the safest option. No problem. This seat is packed with Britax exclusive safety features, including a SafeCell crumple zone to absorb energy, a V-shaped tether for reducing movement, and a high-strength steel frame holding it all together. 

You’ll love just how easy everything is with this seat. The ClickTight installation of this seat is fool-proof and uses your car’s seat belt. The headrest is adjustable and the harness doesn’t require rethreading. My favorite part? The cupholders and removable and dishwasher-safe. Does it get better than that?

While normal car seats run hot, the One4Life aims to keep your child nice and cool, thanks to ventilated mesh fabric and built-in cooling channels for maximum airflow.

Oh, and if you love the cool Teal color featured in the above photo? It’s called Cool Flow Teal and it’s an Amazon exclusive so you better hop on over and snatch it up!

Britax Boulevard ClickTight Convertible Car Seat

Britax Boulevard ClickTight Convertible Car Seat | 2 Layer Impact Protection - Rear & Forward Facing - 5 to 65 Pounds, Circa

The Britax Boulevard ClickTight Convertible Car Seat is another fantastic Britax offering. 

Of course, this convertible car seat can rear-face and forward-face. Your child can rear-face in this seat until 40 pounds. If you’re new to the parenting thing, you might not be sure if 40 pounds is significant or not. Trust me when I say it is. For reference, my son is about to turn 3 years old and he’s not 40 pounds yet!

As always, this Britax seat is safe thanks to the brand’s exclusive safety features. You can’t argue with that steel frame! Meanwhile, while not exclusive to Britax, the five-point safety harness is another feature that protects your sweet baby. 

It’s a comfy ride in the Boulevard since the car seat is constructed with premium fabric and padding. Never fear though – this plush cover is easy to remove when the inevitable happens and the car seat suffers a spill (or two). 

Just how easy is it to clean? One such customer named JayC declared this seat the “best car seat EVER” and they are quick to point out the ease of cleaning. They particularly enjoy that they “don’t need a YouTube video just to put the cover back on.” Amen, JayC.

Oh, and this is the only Britax car seat that comes in my favorite color scheme. It’s called Vector and it’s a geometric mosaic of bright colors. It’s a fun retro look that I think brightens up the entire car seat.  

We’ve compared the Boulevard to other Britax car seats in our comparison article.  

Britax Emblem 3 Stage Convertible Car Seat

Britax Emblem 3 Stage Convertible Car Seat - Rear & Forward Facing | 5 to 65 Pounds - 2 Layer Impact Protection, Dash

The Britax Emblem 3 Stage Convertible Car Seat is everything a great Britax seat has at a surprisingly low price. 

This may be a bit too on the nose to say, but here it comes: the Britax Emblem is emblematic of the brand’s values. It’s safe, easy-to-use, and rather fashionable. Even better, it’s an economical option. 

The Emblem was released in 2018 as an affordable Britax offering. At nearly half the price of other Britax convertible car seats, it is at an affordable price point. However, nothing is sacrificed and no corners are cut in this car seat. 

In fact, despite its price, one customer has declared the Emblem the “Rolls Royce” of car seats. It’s hard to argue with that kind of review! This belief stems from the seat’s simple installation process, its strong safety standings, and general ease-of-use.

The Emblem car seat only comes in neutral patterns, so no wild options here. You won’t mind much though after you figure out that the cover is removable and so easy to clean. 

You may find yourself disappointed in the seat’s lack of cupholders. After all, where do you put the sippy cup and Goldfish crackers? Luckily, Britax does sell a cupholder accessory that is compatible with this seat. Plus, it’s dishwasher-safe!

Britax Allegiance 3 Stage Convertible Car Seat

Britax Allegiance 3 Stage Convertible Car Seat | 1 Layer Impact Protection - Rear & Forward Facing - 5 to 65 Pounds, Static

The Britax Allegiance 3 Stage Convertible Car Seat is a reliable and sturdy convertible car seat. 

Should you be pledging your allegiance to this Britax convertible car seat? I say a hearty yes. I’m not just saying that because you can get it in a fun purple polka-dot pattern that is reminiscent of Minnie Mouse either, but it helps.

The Allegiance car seat has been in production since 2018 and has some serious fans. One feature parents rave about is the padded crotch buckle cover because it eliminates the possibility of pinching little legs. It also stays attached and doesn’t get lost. That’s an annoyance I understand well; I once owned a non-Britax car seat and, after the first month, I never saw that buckle cover again.

Beyond the buckle, this car seat is a comfy napping oasis. The removable body pillow keeps even tiny newborns snuggled up tight. The padding and fabrics of the seat cover are totally nap-friendly, even for older babies and toddlers.

Comfort is important but so is safety. This car seat comes standard with the rigorous safety features we come to expect from Britax products. 

Best Britax Infant Car Seats

Fact: infant car seats are so convenient. Any mother who has transported a sleeping baby from a car to a store can attest to its cozy magical powers. Bravo to the first person to decide we should be able to carry car seats!

The downside of infant car seats is, of course, you can’t use them forever. Despite our objections, our babies just keep growing and growing, meaning they outgrow infant carrier seats. 

Because of this, many parents may choose to skip right over an infant car seat and opt for a convertible car seat instead.

I am not one of those parents! I’m a fan of infant car seats and am thankful for the many months it allowed me to tote around my sweet baby boy. If I could do it all over again, I’d still choose that type of car seat.

Britax also appreciates the art of the infant car seat and has several options if you’re a fan of them like me!

Britax B-Safe 35 Infant Car Seat 

Britax B-Safe 35 Infant Car Seat - Rear Facing | 4 to 35 Pounds - Reclinable Base, 1 Layer Impact Protection, Ashton (E1A183D)

The Britax B-Safe 35 Infant Car Seat is a customer favorite.

In Britax’s most popular travel systems, the B-Safe 35 comes included. This isn’t surprising; this award-winning car seat is unparalleled in safety and comfort.

First and foremost, your little one is protected from the ride home from the hospital up until they hit 35 pounds. Hopefully, you’ll never experience a car accident, but in the event of the unthinkable, your baby is surrounded by side impact protection at the head, neck, and torso.

The seat is made with SafeCell technology that helps absorb energy in an impact. Likewise, the seat’s base is made with an impact-stabilizing steel frame. All of these features are intended to keep your little one safe!

Your baby may be safe, but are they comfy? Absolutely. This Britax car seat has a plush cover that is easy to remove and clean. For the littlest of babies, there is a removable head pillow for support. There is also an extra-large canopy for blocking the elements!

The B-Safe 35 seat is compatible with most Britax strollers, including the B-Lively, B-Free, and Pathway.

Britax B-Safe Ultra Infant Car Seat 

Britax B-Safe Ultra Infant Car Seat - Rear Facing | 4 to 35 Pounds - Reclinable Base, 2 Layer Impact Protection | Cool Flow Ventilated Fabric, Cool Flow Grey (E1C009S)

The Britax B-Safe Ultra Infant Car Seat is the B-Safe 35, version 2.0.

Is this car seat widely different from the B-Safe 35 we discussed above? Truthfully, no. They are extremely similar but they have just a few differences.

The Britax B-Safe Ultra came after the B-Safe 35, as an improvement on the original. Both are still in production today, but the B-Safe 35 was originally released in 2014, while the Ultra wasn’t available until 2018. 

Both B-Safe versions have Britax’s safety hallmarks, such as impact-stabilizing steel frames and energy-absorbing bases. Likewise, both car seats have a weight limit of 35 pounds and are travel system compatible. 

There has to be a difference though, and there is. For example, the Ultra has six adjustable harness positions and the B-Safe 35 only has 4. Even better, the Ultra has a no-rethread system where the harness can be adjusted by raising or lowering the seat’s headrest. You never have to thread the harness through different shoulder strap slots!

The next differences are more about convenience than anything else, but your convenience is worth it. The Ultra car seat features a flip-forward belly pad. Basically, there is a cover over the buckle that ensures it falls forward when not engaged. This means the end of trying to dig the buckle out from under your kid’s butt!

The Ultra also has a European belt guide. This makes the car seat carshare ready because you can install it in a vehicle temporarily without the base. With the rising popularity of ridesharing, more companies are adding this to their seats!

Best Britax Booster Car Seats

In the car seat progression, the booster seat is the last step! With a booster, it’s the only seat that stands between you and doing away with car seats entirely.

While it may be the final step, it’s still one worth doing correctly. We all understand the importance of car seats for babies and toddlers. As kids grow older, though, there isn’t as much emphasis put on car seat safety. Due to this, some parents may think it’s okay to be lax with booster seat use.

The hard truth is that most children are not safe in a car with a seat belt alone. Their short stature puts them at risk when they use standard seat belts intended for adults. Children should be in a booster seat until they are 4’9″ and are between ages 8 and 12, according to the National Highway Traffic Safety Administration. 

Fortunately, Britax has state-of-the-art booster seats that are safe, durable, and look sleek. 

Britax Grow with You ClickTight Harness-2-Booster Car Seat

Britax Grow with You ClickTight Harness-2-Booster Car Seat | 2 Layer Impact Protection - 25 to 120 Pounds + Cool Flow Ventilating Fabric, Cool Flow Gray [New Version of Frontier]

The Britax Grow with You ClickTight Harness-2-Booster Car Seat is another Britax twofer!

Britax’s engineers seemingly have a knack for 2-for-1 deals. While this seat may appear to be merely a booster seat, it’s a harness car seat as well. Traditional booster seats are used to help children reach the height that allows them to use the car’s seat belt properly. This seat does that, but before that, it operates like a car seat – albeit a low profile one!

This special combination seat does give you an opportunity to opt-out of the traditional car seat process. Britax’s infant seats accommodate babies until 35 pounds, while the Britax Grow with You booster car seat can start protecting children at 25 pounds. Basically, you could go straight from the infant seat to this booster combo, saving some bucks in the process.

The Grow with You has all the Britax safety features you’d expect, including the SafeCell technology, the steel frame, and the two layers of side impact protection. Plus, you get to enjoy the simple installation process with the ClickTight system. Open, thread, and close!

The seat is outfitted with ventilated mesh for cool and comfy car rides. Your kid will appreciate most the two cupholders that they can fill with Goldfish crackers.

The harness front-facing component is good for children 25 to 65 pounds. The booster seat works from 40 pounds to 120 pounds. As always, check with local regulations on when children should be transitioned between styles.

Britax Highpoint 2-Stage Belt-Positioning Booster

Britax Highpoint 2-Stage Belt-Positioning Booster Cool Flow Ventilating Fabric Car Seat - Highback and Backless | 3 Layer Impact Protection - 40 to 120 Pounds, Gray

The Britax Highpoint 2-Stage Belt-Positioning Booster is a new addition to the company’s roster.

Although this seat doesn’t have a harness component, it is convertible in the fact that it has two stages: a high back booster and a backless booster. 

The smart design of the Highpoint sets it apart from the other booster seats. Since proper seat belt use is so essential, the Highpoint seat makes it virtually foolproof with a SecureGuard belt-positioning clip and color-code belt guides.

Additionally, your child will be riding in style sat in the spacious build of the Highpoint. It’s roomy without sacrificing security. The seat grows with them as well with the 10-position quick-adjust head restraint. They can also lounge comfortably with the two armrests. 

The high back version can be used by children 40 to 120 pounds. Children use the backless booster from 48 to 120 pounds. Be sure to follow safety protocol and not move your child to the backless version until they are 48 pounds and over 46″.

Britax Skyline 2-Stage Belt-Positioning Booster Car Seat

Britax Skyline 2-Stage Belt-Positioning Booster Car Seat - Highback and Backless | 2 Layer Impact Protection - 40 to 120 Pounds, Dusk

The Britax Skyline 2-Stage Belt-Positioning Booster Car Seat is another recent extension of Britax’s range of booster seats.

Like the Highpoint, this seat also transitions from a high back booster to a backless one. Once you can finally transition to that backless booster, mama, you will be so psyched about all the space you have again in the back seat!

If both the Highpoint and Skyline are two-stage booster seats, how do you choose between the two? For this decision, it’s best to consider car space and the size of your family.

In the previous entry, we discussed the roomy design of the Highpoint. The Skyline, meanwhile, has a slimmer silhouette, making this seat able to fit three-across! You can fit three of these booster seats, or this booster seat and potentially two other seats. Calling all large families!

As you expect, the Skyline has all the safety features. Two layers of side impact protection in a foam-lined shell cushion protect your child. The sides and back of the seat also have energy-absorbing EPP-foam. 

The Skyline expires 10 years from the manufacture date, making it an investment your family will utilize for a long time.

Britax Midpoint Belt-Positioning Booster Seat

Britax Midpoint Belt-Positioning Booster Seat - 2 Layer Impact Protection - 40 to 120 Pounds - DualComfort Moisture Wicking Fabric, Gray

The Britax Midpoint Belt-Positioning Booster Seat is another current Britax booster option.

When it’s time for a “big kid” seat, the Midpoint might be the best choice for your family. While your little one might feel like an adult in this seat, they will be protected just as fiercely as any baby seat.

The deep walls of this spacious seat cushion your child all around, from head to torso to the pelvis. On the sides, they are secured in a shell lined with two layers of energy-absorbing foam.

Britax’s Midpoint has a thing for the number 2. Besides the two layers of side impact protection, it has two cupholders and two armrests. The seat is also made with Dual Comfort breathable and moisture-wicking fabrics.

Parents of tall kids, rejoice! This booster has a 10-position quick-adjust head restraint that is a snap to raise and lower. Your child’s unexpected growth spurts are no match for this seat. 

The Midpoint can fit three-across in the back seat of most cars if need be. To do so, though, you’ll have to remove the booster’s two cupholders. Truly, it’s a small price to pay for to convenience of fitting three children in one car!

This high back booster seat can safely seat your child up until they hit 120 pounds. It has a 10-year expiration date and comes with a one-year warranty.

FAQs About Britax Car Seat

Which Britax car seats are part of travel systems?

All Britax infant car seats can be used as part of a Britax travel system. Strollers in these systems have car seat adapters to allow this.

Meanwhile, convertible car seats and booster seats are not travel-system compatible. These seats are intended to stay based inside your vehicle. If having a travel system is important to you, make sure to look into Britax’s infant car seats.

When do Britax car seats expire?

As with any car seat, expiration dates vary. For Britax car seats, there is a general rule of thumb. Infant car seats expire six years after the date of manufacture. Convertible car seats without the ClickTight install system last seven years. ClickTight car seats don’t expire for 10 years!

To know when a Britax car seat expires, you’ll need to reference the manufacture date. This date is found on a label on each car seat and you can consult the seat’s manual for the exact location. For example, on Britax B-Safe infant car seats, such a label is found on both the seat itself and the seat’s base. 

How do you install Britax car seats?

Installation depends on the seat you choose. Some Britax car seats install using the LATCH system, while others utilize the company’s innovative ClickTight procedure. 

The LATCH system is the most common way to install car seats. It can involve the car’s seat belt or lower anchors. Recent vehicles are equipped with anchors between the seat cushions. You can use these, along with a top anchor found on the seat, to secure the car seat. 

The ClickTight procedure is very simple. A panel in the car seat is lifted and the seat belt is slipped through and buckled. The belt is then locked into place and this secures the seat.

Installation can be hard without visuals. Luckily, Britax offers installation videos to help you with the process. 

How do you remove Britax car seats from the base?

With Britax car seats, only infant car seats can be removed from the base. With convertible car seats, it’s an all-in-one kind of deal.

Removing a Britax infant car seat from the base is a simple procedure. On the back of the carrier, you’ll see a release lever. You will want to pull and hold that lever as you lift the carrier out of the base. 

New Britax infant car seats have this release lever and function the same way. Older models may vary, so consult your product’s instruction manual. 

Where can I find Britax car seat manuals?

The official Britax website includes all of the company’s products’ manuals. The list is comprehensive, includes instructional videos, and even has manuals of retired Britax products.

Of course, when you purchase a car seat, a paper copy of the manual will be included. But, we’d all rather have an electronic copy, right? I hear you.

Are Britax car seats approved for airplane use?

Most Britax car seats meet FAA certifications. To make sure, check your specific car seat. On your seat’s label, if it is approved for airline use, you’ll find red text that reads “This restraint is certified for use in motor vehicles and aircraft.” The company recommends also checking in with the airline before your flight. 

Please note that belt-positioning boosters that do not have harnesses are not acceptable for airplane use since these boosters require a lap and shoulder belt. These include seats like Skyline, Highpoint, and Midpoint. The Grow With You booster seat does have a harness and can be used. 

Wrap Up

Britax offers fantastic options in all car seat categories, including infant carriers, convertible car seats, and booster seats. Brand-specific features like SafeCell Technology and innovations like the One4Life set these seats apart from the competition. 

You just can’t beat a Britax car seat. No matter which variation you go with, you’re investing in a high-end car seat that you can depend on.
