Diono Radian 3R Car Seat Key Features

The Diono Radian 3R is the most basic version of all the Radian models from Diono. Yet, it is still a high-quality seat that provides your little one with the ultimate protection through all stages of childhood. Perhaps the most remarkable feature of this car seat is that you can use it for your kid until they no longer require an infant car seat thanks to the Diono – Radian 3R convertible design.

The Diono Radian 3R can be converted into three positions. You can use it for an extended rear-facing when your kid is between 5-50 lbs, a forward-facing direction from 22-65lbs, and in booster mode for as much as 120 pounds. Additional features of this car seat include

Slim Fit Design

This product belongs to Diono’s line of slim-fit car seats. Car seat models in this category are designed for convenient carpooling. You can fit up to 3 of these into the back seat of your car conveniently.


The Diono Radian 3R has a portable design. It can be folded flat for easy storage in an overhead compartment or the trunk of your car when it is not in use. However, despite being foldable, this car seat is a bit on the heavier side. Our guess is that the added weight is intended to boost safety. But it does not make it any easy to carry the car seat around when you need to.

Is Diono Radian 3R FAA Approved?

Regarding portability, one question you are likely to have is whether the Radian 3R is FAA approved or not. Fortunately, this infant car seat is approved and certified by the FAA for aircraft usage.

Easy Installation

The Diono Radian 3R Car Seat ‎50624 is one of the easiest-to-install car seats you will find around. Thanks to a SuperLatch system, installing this car seat securely requires very minimal effort. Once you hear an audible click, you can be sure that the seat has been installed securely and your baby is safe.

Maximum Protection

The very point of using a car seat is to keep your little one safe in the car and the Diono Radian 3R fits the bill as far as safety is concerned. The car seat features reinforced automotive-grade steel which helps to maintain stability and sturdiness. There is a thick layer of energy-absorbing foam further reinforced with aluminum on the side of the seat for additional impact protection.

  • Safe Stop Technology to minimize crash force in kids of up to 40lbs
  • Expandable sides and large bottom for enhanced leg support and optimal comfort
  • Foldable design enhances portability and easy storage
  • Easy installation


  • No infant insert

Does the Diono Radian 3R Have a Cup Holder?

The Diono Radian 3R does not have a cup holder to hold snacks and water which is quite a bummer considering it is a standard feature in most car seats today. However, Diono sells a cup holder as a possible add-on that you can purchase separately. You can opt to purchase this if your kid will be snacking in the back with this seat. It is very much recommended if you want to avoid a mess.

Do Diono Car Seats Become Boosters?

When your kids outgrow a forward-facing seat (you can check for weight and height instructions for this in the Diono Radian 3R Car Seat Manual), they need to graduate into a booster seat. This type of car seat is designed to position the kid in a way that allows their shoulder and lap belt to fit properly as adults’ seats would but with added safety. Booster seats also help your kids learn some independence.

The Diono Radian 3R Car Seat can be easily adjusted into a high back booster seat suitable for kids of up to 120lbs. it provides added protection for kids that are transitioning into booster mode.

What’s the Difference Between Diono 3R And 3RX?

The Diono Radian 3R and Radian 3RX are two very similar car seats from Diono. Both have pretty much the same features and specs. The only remarkable difference between them is that the 3RX comes with a removable head support insert for infants.

This insert further provides cushioned support for your little one. It can be removed as your kids grow. The Diono 3R does not have this feature. But it is still high quality and very comfortable car seat that provides your kids with ultimate protection.

How Long Are Diono Car Seats Good Before They Expire?

Radian seats have a long expiration date of about 10 years from the date of their purchase. They are made with durable fabrics with a reinforced steel core constructed from high-strength automotive steel material. This ensures that the car seat continues to shield and protect your kids for several years.

The fact that this car seat can also be adjusted to achieve different custom fit from birth to up to 120lbs weight makes it even more impressive for long-term usage.


The Diono Radian 3R Car Seat ‎50624 is the most basic of all the Radian models. Thus, you may not find many of the advanced features you will find on other Radian car seats from the Diono brand.

Still, this is a high-quality car seat engineered to keep your kid safe for several years without compromising on comfort.
