Diono Radian 3QXT+ Latch Convertible Car Seat

Luxury Travel from Birth to Booster in the Diono Radian 3QXT+ All-In-One Convertible Car Seat

One of the standout features of the Diono Radian 3QXT+ is its versatility. Designed to adapt as your child grows, this convertible car seat promises 10 years of first-class travel from birth to booster. With a weight range from 4 to 120 lb (1.8 - 54 kg), this car seat ensures that your child is securely accommodated at every stage of their development. The ability to transition seamlessly from rear-facing to forward-facing adds to the convenience, making it a one-time investment that covers all your child's travel needs.

Diono Radian 3QXT+ Safety Rating

The Diono Radian 3QXT is rated as a “Best Bet” by the Insurance Institute for Highway Safety. This is due in part to its Safe+® Engineering, a combination of unique engineering features and rigorous testing that adheres to the highest safety standards. This comprehensive approach aims to create the safest car seat possible, giving parents the peace of mind they need while on the road. Knowing that your child is surrounded by cutting-edge safety features adds an extra layer of confidence to the overall driving experience.

The Safe+® 2-in-1 anti-rebound panel is another testament to Diono's design philosophy. When rear-facing, this panel increases stability and reduces rebound rotation by up to 50%. This added layer of protection ensures that your child is secure in the event of an unexpected impact. Additionally, the adjustable calf support and comfort liner provide extra comfort during the transition to forward-facing, creating an even more comfortable ride for your little one.

Diono Radian 3QX vs 3QXT

The Diono Radian 3QXT is basically a sibling to the 3QX, sharing all those awesome features that parents adore. The key difference between the two is a boost in side impact protection, particularly within the infant insert. The 3QXT boasts an additional infant liner, complete with a newborn protection insert that cocoons your little one like a nest. They've even thrown in extra harness pads for the tiniest passengers. This means the 3QXT steps it up with 4 stages of infant newborn protection, while the 3QX offers 3 stages. The 3QX already offers six layers of side protection with interlocking EPS & EPP foam, encased in high-density plastic and steel reinforcement, but the 3QXT takes it up a notch, offering a total of eight layers for that extra peace of mind.

What Parents Are Saying About the Diono Radian 3QXT

Read what these families love about this safe, comfortable convertible car seat:

“We have been using this seat since day one. He has always been so snug and secure in this seat. I love that it comes with the infant padding, it's sturdy and has the anti-rebound/adjustable leg rest. It's easy to install in my vehicle and I've been able to properly fit this seat in several different cars including a Hyundai Sonata, Nissan Altima, and a Toyota Tundra. I'm so happy I purchased this seat and wish I did with my other kids who are now teens. Having a seat that can last 10 years would have saved buying so many different car seats. I recommend this seat to everyone who asks. I just can't say enough good things about it.”

“My kid loves it, and the straps and latches are extremely easy to use. (I've used a few other brands for years, like Graco for reference, and older models were clunkier.) It seems extremely supportive with the surrounding high-back wing walls, like a racing bucket seat. Memory foam is a nice touch, and the shoulder pads are cushy. Aesthetically, love the all-black seat look. We use it forward-facing in a Tesla Y SUV, and the Diono white lettering on the side reads very clearly through the dark-tinted windows. Looks kind of nice actually. Adjustability is straightforward, instruction booklet was clear (definitely read it for key instructions on some of the misc. parts and strap placements.) 10/10 recommend.”
