If we could sum up the Radian 3RXT in four words, it would be “luxury”, “safety”, “features”, and “narrow” (narrow in a good way). In short, the 3RXT is among the highest-end of convertible car seats, and it shows in the quality of the seat (and its high-end price).
Here’s a quick rundown of this model’s features:
Diono Radian 3RXT Overview
The Radian 3RXT is an extremely stylish and luxurious convertible car seat. The design includes forward and rear-facing modes in addition to a booster seat to help ensure this is the only car seat parents will need to purchase for their child. Diono has a well-deserved reputation for manufacturing narrow car seats. This enables parents to install three separate car seats to accommodate multiple children.
The design of the car seat takes modern cars into consideration. This ensures the car seat will fit well into smaller vehicles. Parents need to be aware the Diono Radian 3RXT is at the high-end. If the parents are on a tight budget, this car seat is most likely not an option. The Radian 3RXT is an expensive purchase including exceptional safety features, comfort and luxury.

Diono Radian 3RXT vs Diono Radian 3QXT
The Diono Radian 3RXT is part of a series of convertible car seats to make the life of the parents easier. The Radion series was designed so parents could install three car seats in the rear of the vehicle safely and comfortably. Infants can use either model from the time they are born until approximately the age of 10. This eliminates the need for parents to purchase more than one car seat per child.
Both models are similar with just a few differences including shape, and the type of infant insert. The biggest difference is the steel anti-rebound bar for the rear-facing mode is not included with the Radian 3RXT. The Radian 3QXT accommodates children from four to 50 pounds, while the weight range for the Radian 3RXT is between four and 50 pounds.
If there is a premature baby, the difference in weight is important. The Radian 3QXT includes a newborn wedge, extended sidewalls, and a steel core missing from the Radian 3RXT. The Radian 3QXT has received more aggressive testing for 2x impact force, rear impacts, and rollovers than the Radian 3RXT. Since both models are made by the same manufacturer, there are also a lot of similarities.
Both models allow three car seats to be placed side by side in an average-sized vehicle. Both also offer the quality of Diono. Both models are manufactured using dual spines to ensure comfort. The Radian 3RXT and 3QXT provide memory foam, a cup holder, 12 positions for the headrest, low seats, side impact protection and an anti-slip harness.
Although the child will be very comfortable in the Radian 3RXT, the car seat does not offer the latest technology available with the Radian 3QXT. Both offer comfort and a safe ride, but the Radian 3QXT provides a slight edge regarding safety. Parents will be pleased with the features, benefits, and safety provided by both models.

The Bottom Line
The Radian 3RXT offers parents an excellent safety record nearly impossible to beat and dependability. For parents with three children, the option to install car seats in the rear of the vehicle for all three is ideal. The car seat will grow with the child, effectively eliminating the need to spend more money on another car seat later on. This ensures the Radian 3RXT is a cost-effective purchase.
Parents can continue using the same car seat until the child reaches 120 pounds or surpasses the height limitations. The installation is fairly simple due to the UAS connectors. Keeping the seat cover clean is easy because it can be removed. Parents interested in quality, safety, comfort, and luxury should seriously consider purchasing the Diono Radian 3RXT.
