Diono Radian® RXT Just My Color Convertible+Booster Car Seat


Looking good with your squad!

Your child’s security is a top priority. Diono engineered the Radian® rXT Just My Color with premium, innovative features like a steel alloy frame, aluminum reinforced sidewalls, energy absorbing EPS foam and a reinforced adjustable head support to keep your little one protected and comfortable.

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.) the long-range lifespan protects your child facing forwards. Peace of mind for you, Diono thought of everything so you don’t have to.

Lovingly Engineered

The Radian® rXT JMC 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. Deep, aluminum reinforced sidewalls provide excellent side impact protection, while energy absorbing EPS foam surrounds your child for ultimate safety. 

Three’s not a crowd

For safety that fits 3 across the Radian® rXT JMC packs all 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.

First Class comfort 

Inspired by the best European fashions, the Radian® rXT JMC 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.


Side Impact Protection

Your child’s safety is covered. Radian® rXT JMC 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.

SuperLATCH™ Installation

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

Safe Stop®

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

Rear-Facing Tether

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