First Class comfort: Inspired by the best European fashions, our Radian 3 rXT has soft fabric covers and a memory foam seat base bottom. Lined with thick energy absorbing foam, comfort and safety go hand in hand. A tailored infant support cushion and a cup holder are included.

Joy of the journey: From birth, keep your little one rear facing longer to 45 lbs traveling safely. As they grow to 120 lbs (12 years approx.) our long-range lifespan protects your child facing forwards. Peace of mind for you, we’ve thought of everything so you don’t have to.

Lovingly engineered: The Radian 3 rXT is fabricated using super strong automotive high strength steel, engineered into a dual spine. This unique core manages and dissipates energy and provides an unyielding structure to protect your baby. We shield your precious child through Super side impact protection with aluminium reinforcement.

Three’s not a crowd: For safety that fits 3 across the Radian 3 rXT packs all our innovative safety features into a sleek and slim design that allows you to fit three across (in most mid-size vehicles). Now the whole family can travel, together.

Made of Seattle: We are from Seattle, a city where being different is the norm and so is the Radian 3 rXT. It folds flat, so you can travel the world and is FAA approved for use on an aircraft. You don’t need to change just because baby is in tow.

SuperLATCH™ Installation
Our unique SuperLATCH™ system makes installation easy and secure. An audible click and visual indicator let you know when the connectors are locked.

Side Impact Protection
We’ve got your child’s safety covered. Radian® 3 rXT seats feature deep, aluminum reinforced sidewalls that extend straight forward and are lined with thick, energy absorbing foam. We performed rigorous side impact testing to achieve the proper size, shape and strength that best protects children from side impact forces.

Safe Stop®
Our patented Safe Stop® harness component is a load-limiting device that absorbs energy in a crash. The unique design offers an additional layer of protection by reducing impact to a smaller, forward-facing child.

Rear-Facing Tether
As safety experts, we think of every precaution. Rear-facing tether capability helps reduce seat rotation during an impact. This unique feature is not found on every car seat. We built it in here for an extra layer of protection when your child is rear-facing.

    A+ Car Seat

    Posted by Sandra on Jun 11th 2019

    Knowing that our baby was about to outgrow her infant seat, but my nerves in high gear. I think I spent most of my pregnancy researching infant seats, and only glanced at convertibles, figuring I would have one chosen before needing one. We tested cleks, nunas, maxi-cosis, and the Diono's were a pleasent surprice. They were sturdy, without being too hard, and the fabrics were very cushiony, without a high-price tag. The true test was the easy of installation, we got a chance to test it at kidsland, and take it down to my car, and was super easy to install. There's a bit of weight to it, but that's expected, but the latches snap on easily without having to manuever and pretzel myself to install.
