Diono vs Britax Car Seats: The Final Countdown 2022
To help you choose better and narrow your search, I inspected two car seats: the Britax One4Life ClickTight convertible car seat and the Diono Radian 3RXT 4-in-1 convertible car seat.
We will compare their crucial factors together, and you can eventually pick the best solution. Shall we?
1. Design and Specifications
As you'll find, both car seats are convertible, with a 3-in-1 that is a 4-in-1 system, so they have the same goal and purpose. You can use only one car seat for an extended period.
Thus, the convertible car seats support all kids, from infancy to their school ages, respectively:
- Rear-facing infant car seats - for kids 5-50 pounds
- Forward-facing convertible car seats - supporting kiddos 22-65 pounds
- Booster mode (high back seat belt-positioning booster seat) - accommodating children up to 120 pounds of the maximum weight limit.
None of the seats include a backless booster seat & you'll have to turn to different models for this benefit.
And, you need to follow the correct child seated shoulder height to use the belt system correctly.
However, the NHTSA and the AAP strongly recommend keeping your little ones in the rear-facing mode of the infant car seat as long as possible. That's the safest position for them.
For this reason, both brands offer the fourth mode - the extended rear-facing mode of the infant car seat for kids between 5-50 pounds.
So, they also increased the rear-facing height limit, the Diono Radian 3XRT up to 57 inches, and the Britax up to 63 inches.
A typical infant car seat accommodates kiddo between 5 and 35, or 40 pounds. But, they both include the rear-facing car seats with the infant insert.
However, due to the advanced design and higher weight and height limits, Diono and Britax brand will provide more child safety standards for your infants and newborns in the child rear-facing mode.
The two-car seats differ in their specifications.
As you'll see, the Britax seats are generally bulkier and more robust than competitors. On the other hand, the Diono seats are narrower in design and weight.
Thus, our Britax One4Life convertible car seat weighs 30 pounds and has the following dimensions: 20.5 x 19.5 x 25 inches.
On the other hand, the Diono Radian 3RXT convertible seat is a lot smaller, with the following proportions: 16 x 17 x 28.5 inches and weighs 28.1 pounds.
The Diono Radian 3RXT will fit three child car seats in the back of your vehicle, while you may have issues adjusting the Britax with other car seats at the back seat of your vehicle.
However, both are pretty bulky, so neither will be too quick and effortless to move around the vehicles.
But, if you want a narrower seat, then the Diono Radian 3RXT should be your first choice.
On the other hand, if you want a bulkier convertible car seat for more stability and reduced movement in car accidents, the Britax One4Life is a life savior!
Finally, both car seats include ten years of a lifespan, so you can use them for an extended period.
I will leave the decision to you in this Diono vs. Britax round.
2. Car Seat Safety Features
Only a few car seats provide maximum safety standards for rollover accidents, the most dangerous ones.
The Britax One4Life convertible car seat is the safest convertible car seat you can find on the market. The convertible/booster car seat grows with your child and follows their development.
The car seat offers two layers of side-impact protection, a reinforced steel frame and the energy-absorbing foam.
So, it will keep your child's head, neck, spine, and other crucial body parts safe and stable on the road. It will keep them intact in the crash.
In addition, the Britax booster car seat uses the famous SafeCell Technology with a crumple zone to offer better head support and keep your little one stable and secure in an accident.
It will absorb and redirect all external forces, impacts and pressure and redirect them around the frame and shell. So, the steel alloy frame won't damage so soon, and your baby will be safe.
The V-shaped tether will also contribute to maximum safety features, as it reduces movements and makes it more stable in crashes.
On the other hand, the Diono Radian 3RXT is an advanced booster car seat due to its safe and comfortable newborn positioning.
When used in the rear-facing infant car seat mode, the Diono Radian 3RXT features a brand-new newborn travel high wedge, creating a secure and safe lie-flat travel position.
The innovative technology pushes the baby up, reducing the head slump, and helping keep the airways open.
And as your child grows, you can quickly remove the wedge to allow the two-in-one infant positioning liner for additional support.
Additionally, the reinforced steel core, the Diono engineered impact stabilizing steel frame, and the car seat protectors will provide maximum user protection.
So, due to the metal alloy frame, the Diono Radian 3RXT is an ideal convertible car seat for your needs. But, it also offers side-impact protection for a safe and secure ride.
However, you will need additional layers of the side-impact protection for a potential car accident, as it absorbs all pressure and forces, keeping your little ones stable.
Both car seats have 5-point harness systems in the rear-facing and forward-facing modes for extra stability.
So, in combination with the high-strength steel frame, I choose the Britax One4Life convertible car seat rather than the Diono Radian 3RXT.
In addition, Britax got multiple awards for the best car seats in safety standards numerous times, so I trust it more.
3. Installation Procedure
The Britax convertible car seat is well-known for its ClickTight installation system.
The system allows you a three-step installation procedure: open, thread the seat belt in the belt path, and close to lock the car seat.
Of course, you can install the car seat either with the LATCH or seat belts. But, you must refer to the car seat and vehicle instruction manuals.
However, Britax recommends you use the vehicle's seat belt to install the seat, as you will avoid all LATCH complications.
On the other hand, the Diono Radian 3RXT offers the Super LATCH installation system and the belt system. So, you must again refer to the car seat and the vehicle's instruction manuals.
It would help to find the vehicle's LATCH attachments and the proper lower anchors of the car seat. Again, pay attention not to twist the straps.
Now, the choice is still yours, depending on what you like more and what suits you better.
Yet again, I still prefer the Britax car seat for the super-easy installation in all positions and the locking mechanism to keep the car seats secure and stable.
Of course, the Diono seats also offer easy installation with the LATCH connectors, but you might find it difficult, especially if you're a newbie.
Anyhow, when you don't know how to install car seats correctly, please refer to a verified CPST to help you and guide you through the process.
4. Comfort Benefits
Concerning comfort features, the Britax One4Life undoubtedly surpasses the Diono Radian 3RXT car seat.
The Britax model offers a no-rethread 5-point harness. So, you don't have to install and remove it as your kid grows.
The harness will adjust to their weight and height, and you can only moderate it for a proper fit.
On the other hand, the Diono Radian 3RXT has a rethread harness, so you will have to remove it and re-route the straps through the car seat's back. This is time-consuming and complicated.
So, Britax wins this time.
In addition, the Diono Radian 3RXT offers 12 headrest positions for reduced head slump and better support. But, Britax utilizes 15 headrest and harness positions for maximum coziness.
You'll also find nine recline positions for the Britax car seat, while the Diono car seat uses only two recline positions.
This is crucial when speaking of multiple road trips, as the kids will spend more time inside the car seats. The positions won't cause pressure or pain and will keep them optimal.
Again I vote for Britax.
Now, both seats include comfortable material and premium-quality content.
The Britax seat also has built-in cooling channels and ventilated mesh to keep your kiddo relaxed, calm and cool in the seat.
The Diono seat also includes high-quality materials and durable, reliable, ventilated content for maximum comfort.
But, overall, Britax offers the most comfortable car seats, which beats Diono in this category. So my vote goes to Britax.
5. Extra Features
Cup holders are an inevitable part of any travel.
Your angels can place their food and beverage inside and keep them near when hungry and thirsty. And, you can focus on the road better.
So, Diono offers only one removable cup holder, while Britax includes two built-in. They are effortless to wash and maintain when your kids get too messy.
I would go with two for my kids, but one is fine if your kids are not too demanding. The more, the merrier!
But, regarding extra car seat accessories, Diono has multiple, such as:
- Baby carriers,
- Padded stroller liners,
- Stroller accessories,
- Stroller boards,
- Back seat organizers, etc.
Britax also offers multiple stroller accessories:
- Strollers,
- Buggies,
- Secure installation for the car seat base - European guides and LATCH system,
- Baby carriers and similar accessories can also be valuable for the best car seat use and standards.
6. Ease of Use and Maintenance
Both car seats have a removable, machine washable cover to ensure effortless cleaning and maintenance process.
So, it will save you time and energy, and you can air dry the seat cover to ensure maximum freshness for subsequent use.
However, the Britax system uses the quick-to-remove seat cover that you can quickly remove from the frame, making the operation effortless.
But, you can choose according to your preferences, so I'll leave it to you.
7. FAA Approval
To check whether your car seats are FAA-approved, you should find a label stating that they are optimal for motor vehicles and aircraft use. It should be at the side or the back of the car seat.
If the seat doesn't have such a sticker, you cannot use it on the plane.
Luckily, both Diono and Britax car seats have this label, so they are both optimal to use for the aircraft.
However, you must use them only in the rear-facing or forward-facing harness mode! Never use them in the booster mode, as the rules won't allow you.
Remember that there's no such thing as an airplane booster seat, only harness modes.
In addition, I suggest you contact your airline to find out if they have additional requirements regarding car seats.
Otherwise, you will have issues when passing the airport checking and control. Prepare in advance to avoid complications.
8. Price Tags
Regularly, both car seats cost around $350 and $400. However, the Diono is currently on sale on Amazon, so that you can get the seat for around $260. And you will save 25%.
So, if you still prefer Diono, hurry up and use the discount.
But, their regular price is $50 different; Britax is more expensive.
However, Britax includes better safety standards, more comfort benefits, and overall design, so you might pay more to get the premium benefits.
On the other hand, Diono also offers maximum comfort benefits, but it lacks specific points Britax includes.
Overall, it is a good car seat, but not as good as Britax. But you undoubtedly get what you pay for, and it will make the best use. So, don't worry.

FAQs
Britax Skyline vs. Diono Cambria: Which is better?
They offer pretty much the same benefits.
Both are remarkably lightweight seats, weighing around 12 pounds.
Diono weighs exactly 12 pounds, while Skyline weighs 12.1 pounds. So, if you need to remove the seats quickly, you won't have a headache.
However, Diono offers a slightly narrower seat so that you can use it for public transport or similar carpooling functions. And you don't need to assist your children when using the seat.
The Skyline doesn't have this benefit, so you must lend a helping hand when children use the seat.
But, since it's user-friendly, the seat offers a belt to keep them secure and stable in forwarding movements.
Finally, Britax has a higher price than Diono, so you can choose as you like. But, if you prefer narrower seats, go with the Cambria model.
Britax Highpoint vs. Diono Monterey XT: Which is better?
According to the experts at the BabyGearLab, one of the leaders in testing car seats, the Diono Monterey XT seems more advanced and better than the Britax Highpoint.
Diono has better crash test results; it was in second out of eight places, whereas the data for the Highpoint couldn't be easily collected.
This means the seat is usually not suitable enough for purchase.
Lastly, Diono offers a 9.0 rating out of 10, which is much better than the average 7.2 rating for boosters.
Unfortunately, the ratings and data for the Highpoint again don't have much information for a complete comparison.
Diono vs. Britax high back booster: Which is better?
Well, we have reviewed the two most prominent all-in-one car seats for a complete contrast. These are the Britax One4Life and the Diono Radian 3RXT.
Both convert to the high back belt-positioning boosters and offer an extended use for your older kids.
However, the Britax model seems more advanced regarding safety, comfort, and installation.
The seat has a double-layer of the SIP and the other SafeCell technology for extra security and support for your child.
The Diono seat lacks this additional technology, so it cannot surpass the opponent.
In addition, Britax offers more harness, headrest, and wholesome reclining options, while Diono is limited. Besides, Diono has to rethread the harness so that things may get too complicated.
And the ClickTight installation takes only a couple of seconds for a correct setup, so Britax models are all bells and whistles.
Does Britax offer more accessories than Diono?
Well, not really.
On average, they offer a similar number of accessories concerning strollers and car seats.
Both brands include additional support for strolling and driving, and you can choose the most valuable one for your needs.
You can refer to the Extra features part above in the article, find the available items, and purchase them for your and your kids' needs.
Diono vs. Britax: Which is easier to install?
Britax is undoubtedly easier to install, thanks to its ClickTight system.
It offers three steps for the quickest installation - open, thread the belt, and close to lock it.
Diono offers a Super LATCH installation system. It's straightforward, but it may be hard for the first-time installation.
In addition, the harness is a no-rethreading one, so you don't need to thread it through the back of the seat. So, you will eliminate delays, possible twists, and similar challenges.
Are Diono car seats FAA approved?
Yes, they are. Of course, not all car seats are FAA-approved, only those with the label. So, find it on the seat's side or the bottom part to see whether you can or cannot use it on the plane.
Remember that you can use the seat only in the harness mode, never in the booster method.
Is Britax safer than Diono?
Both seats offer exceptional safety standards. However, Britax seems slightly better and a bit more advanced than the opponent.
It has two layers of the SIP and the SafeCell crumple zone system, whereas Diono lacks an advanced design. Instead, it offers the SIP and standard durable steel shell and frame.
But, Britax has higher safety ratings, so it seems better on the wholesome scale.
Will Diono car seats last longer than Britax?
No, it won't. Both seats have the same expiration period - ten years from the date of manufacture. They support infants and older kids.
However, if you have an accident, you must replace the seat instantly!
You never know whether the inner structure has cracks, so you mustn't risk your child's safety. So, the expiration date is immediate in the case of a crash.
So, Britax vs Diono Car Seats: The Final Verdict
I hope the article was helpful and valuable enough to help you decide what brand is better. So, do you have a definitive solution?
I would choose Britax over Diono due to safety, comfort, and installation standards, but it doesn't mean you should neglect Diono.
On the contrary, Diono is supreme in all benefits, one of the leading brands on the market. So, whatever choice you make, you cannot go wrong.
Let me know once you choose the final winner to share your experience with. Then, you won't regret them!
