The Diono Radian 3 QX Car Seat is a great option for families looking for a three-in-one seat. The price tag may be more than the Diono “R” models but the “QX, QXT, and QXT+” are worth the investment if you don’t want to be purchasing a new seat every few years as your child grows. With the weight capacity ranging from 4-120 lbs, you will be sure to get the most for your money in this seat. We always recommend keeping your children rear-facing for as long as possible, so Diono’s three stages of rear-facing options is ideal as your little ones grow. You can keep your child rear facing in this seat up to 50lbs.

So, what does the Radian 3 QX include? If you opt to forgo the traditional infant bucket car seat you’ll love the included newborn travel high wedges to keep them safe and supported while they are so tiny. Additionally, Diono has included a two-in-one infant positioning liner and a safe anti-rebound bar for full rear-facing protection. This seat includes an automotive-grade steel core with six layers of interlocking foam, high-density plastic and steel reinforcement. Even though there is so much going on with this seat, it maintains its slim design.

Diono Radian 3 QXT All-in-One Convertible Car Seat

So, what’s the difference between the Radian 3 QX and the Radian 3 QXT? Well, the Diono Radian 3 QXT has everything listed above plus these great additional features.

Additional Features:

• Additional head support
• Additional rear-facing options
• A folding feature.

One of the first things you will notice about this car seat in contrast to the 3 QX is the additional head support and padding for newborns and infants. We all know how frustrating and painful it is to watch your sweet babe fall asleep with their head hanging in an awkward position. This car seat helps rectify that situation! This seat also has one additional rear-facing option so your children can sit back-facing for longer. This can bring additional peace of mind when you’re heading out on those long road trips! Finally, this seat has a folding feature making it easy to transport and store – especially on an airplane!

Diono Radian 3 QXT+ All-in-One Convertible Car Seat

The final Diono seat in the Radian Q car seat series is the Radian 3 QXT+. If you’re going for longevity and luxury, this seat is calling your name. So, what sets the Diono Radian 3 QXT+ apart from the 3 QX and 3 QXT models? The 3 QXT+ has everything we spoke about above plus these additional premium features.

Additional Features:

• Calf support
• Cup holders
• Premium fabric

Suitable for children weighing 4-120 lbs, the Diono Radian 3 QXT+ has included calf support for those little legs to make sure they aren’t hanging over the edge of the seat as they grow. It comes with cup holders for snack time and premium fabric for look and comfort. With additional mesh panels and a car seat protector, all while being machine washable, this seat is everything you will need and then some! As mentioned with the above seats, this seat may be packed with features but it can still fit three across a medium-sized sedan.
