Why I Love Diono: The Best Diono Car Seats Reviews

#1. Diono Radian 3QXT - The Best Diono Car Seat for Infants

All Diono Radian seats have almost the same design, yet Diono Radian 3QXT includes a series of specifically adapted features that make it the most suitable for newborns.

Let's see what these are!

First of all, this Slim-fit Diono car seat has a removable newborn insert made from super-soft, energy-absorbing material to surround your baby with nothing but comfort and safety from day one.

Additionally, it includes an infant positioning liner and small-sized harness pads that perfectly align with your baby.

Newborns cannot hold their heads upright, and often inadequate car seats cause a head slump. Diono specifically designed a newborn travel high wedge that allows a near lie-flat position.

Another reason why I find this seat fantastic for infants is the extended rear-facing use. 

Namely, the seat can be used in a rear-facing mode for up to fifty pounds (approximately four years), but you can also use it in a forward-facing and a booster mode (up to 120 pounds).

With such a vast weight capacity, you'll be using this seat for around ten years, and it will certainly last that long thanks to the upgraded steel core made of automotive-grade steel.

On top of everything, this car seat provides unmatched safety with eight layers of combined EPP and EPS foam, forming side impact protection and an anti-rebound bar that reduces rotation by half in the case of a collision.

The seat meets all the NHTSA safety standards and can be used on aircraft.

#2. Diono 2020 Radian 3R - The Best Diono Convertible Car Seat

Moving on to the best convertible car seat from Diono - Radian 3R, another model in their slim-fit line, but this one was initially designed to enable the most effortless transition between the modes.

With convertibles, I find it essential that you can accommodate your kid in all three positions for long enough, and this seat is one of that kind.

It supports extended rear-facing use from five to fifty pounds, forward-facing use from twenty-two to sixty-five pounds, and a booster mode up to 120 pounds.

Since this is the original Slim-fit model, it is incredibly convenient for carpooling, enabling you to fit three across the back seat, and due to its foldable design, it proves quite handy for traveling.

Like the previous Diono car seat, Diono Radian 3R incorporates the reinforced automotive-grade steel frame that keeps the car seat stable and sturdy.

What is more, the sides are reinforced with aluminum and a thick layer of energy-absorbing foam for efficient side impact protection.

I love how easy to install this seat is!

Its SuperLATCH system provides a genuinely secure installation with minimum effort. Wait to hear the audible click, and your child is safe and sound.

As for the handy additions, I would single out the anti-slip harness pads and comfy memory-foam padding that honestly make the difference in your child's experience.

Since things get messy with kids in seconds, you'll appreciate the removable covers that you can put into the washing machine and put back on clean.

#3. Diono Monterey XT Latch - The Best Diono Booster Car Seat

Kids sure can be unpredictable, but there's one thing you have to expect - they grow fast! While you adapt the forward-facing seat, they are ready for a booster!

But, don't panic; if you haven't bought a convertible with booster mode, Diono has your back with Diono Monterey XT Latch.

The first advantage you notice about this car seat is how incredibly adjustable it is.

Its innovative design supports your child from forty to 120 pounds (4-12 years) and converts from a high-back booster seat to a backless booster car seat.

Unlike the previous two models, this booster car seat is honestly lightweight and thus very portable. Transporting the seat from one vehicle to another won't cause you any trouble.

After the third year, your child grows fast and changes drastically.

Luckily, Diono Monterey was designed to follow these changes with twelve headrest positions and an extraordinary dial on the back that allows a 69% increase in occupancy space.

With a simple turn of the dial, you can expand the seat to the target dimensions.

But I guess, before anything else, you care about safety.

Diono Monterey has been tested to exceed the Federal standards and includes the reinforced side impact protection with aluminum head support and a thick layer of energy-absorbing foam.

On top of everything, the seat includes two retractable cup holders so you can keep the snacks and drinks close to your child. Therefore, as you see, it is super functional for traveling.

#4. Diono Radian 3RXT - The Best All-in-One Child Diono Convertible Car Seat

Next, as the cherry on top comes one all-inclusive Diono convertible car seat, very elegantly designed and advanced to exceed all the market standards.

But don't let the chick look fool you; there is a rock-solid construction underneath ready to withstand all the unpredictable situations, protecting your child.

Let's see what this model is about!

As soon as you see all-inclusive, you know what's cooking.

The seat features a rear-facing, forward-facing, and booster mode, providing accommodation to kids from five to one hundred and twenty pounds. It also provides a longer rear-facing use for up to fit pounds.

The rock-solid construction I mentioned includes the alloy steel frame, aluminum reinforced sides, covered in EPS foam, and memory foam to surround your child with cloudy comfort and coziness.

Layered side impact protection makes sure your child is cradled and protected in crashes, while the easy-click super LATCH system enables secure Fit and easy installation.

Since the statistics say that 70% of car seats are incorrectly installed, this means everything since there's not much space for a mistake.

Moms love this Diono Radian 3RXT seat because it comes with removable covers that can be washed in a machine, so everything remains clean and fresh.

Also, despite its all-inclusive design, the seat is slim-fit, allowing you to fit three across.

Are you flying with your child? No problem. Fold the seat flat, bring it to the airport and use it on aircraft; it's FAA-approved!

Finally, it comes in a number of different colors and designs at a price, well reasonable considering the quality and durability of the seat.

#5. Diono Cambria 2 Latch - The Best Child Booster Seat For Girls

If you plan to surprise your little princess, a booster car seat is definitely one of the ways to do it.

A predecessor of Diono Monterey, Diono Cambria is another high-quality, convertible booster seat with an adorable pink design, especially attractive for girls.

Both Diono Cambria and Diono Monterey support kids from forty to 120 pounds and can be used in two modes: a high-back booster and a backless booster.

On the other hand, Diono Cambria has six headrest positions while Monterey has eleven.

Also, Cambria does not have a weight and height expander. Still, it measures 15.5 inches in width, so the seat is pretty wide as it is.

These differences do not make Diono Cambria any less efficient from Monterey. Cambria also features deep side-impact protection and exceeds safety standards. 

What is more, the seat is ergonomically designed and perfectly follows your child's physique for maximum comfort.

Another fantastic advantage of Diono Cambria is the upgraded material, soft and gentle on the skin but also removable. The covers are straightforward to maintain; take them off, wash in a machine, and put in a dryer.

Cambria is also great for traveling since it weighs very little and comes with two retractable cup holders for maximum convenience.

Finally, despite all the fantastic advantages, this car seat comes at an honestly reasonable price, so compared to the previous model, it is more affordable.

#7. Diono Solana 2 Latch - The Best Diono Child Backless Booster

If you're spending most of the time on the road, you sure need a helping hand to stay ahead of everything.

Backless booster car seats are super convenient for traveling for its ultra-light design and high portability, allowing easy transfer from one car to another.

The Diono Solana backless booster car seat weighs barely 6.6 pounds, yet it supports children from forty to a hundred and twenty pounds. This is precisely the same as the high-back boosters I reviewed thus far.

Although designed to provide maximum safety and security, the Solana car seat is straightforward to install and connect due to integrated LATCH connectors and front adjusters.

Also, Diono has redesigned its backless booster seat to provide better access to vehicle buckles. So, trust me when I say the installation is child's play, honestly.

If there are no LATCH anchors, place the booster seat on the car seat. If there are LATCH anchors, use the LATCH system on the Solana booster.

This seat is also great maintenance-wise. You can remove the fabric cover, throw it into the washing machine, and wash it at 86°F/30°C/Cold.

Why should you consider a backless booster at all?

Backless booster car seats are incredibly convenient for carpooling and frequent vehicle switches. These seats take up very little space and never weigh too much.

Diono Solana is exceptionally efficient because it has precisely the same bottom-weight limit as the high-back booster, which is not very common.

And of course, it does not cost as much.
