Car Seat by Diono
Unmatched safety. All-in-one simplicity.
Your child’s security is Diono's top priority. Your child’s security is Diono's top priority. Diono engineered the radian® 3rX with premium, innovative features like a steel alloy frame and energy absorbing EPS foam to keep your little one protected and comfortable.
Some say three’s a crowd. We say, the more the merrier! The radian® 3rX car seats fit 3-across in most mid-size vehicles.
- Joy of the journey: From birth, keep your little one rear facing longer to 20.4 kgs, traveling safely. As they grow to 54.5 kgs (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® 3rX 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. Our audible click SuperLatch system makes installation easy and quick.
- Three’s not a crowd: For safety that fits 3 across the radian® 3rX 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.
- Business Class comfort: Inspired by the best European fashions, our radian® 3rX has bright soft fabric covers and a memory foam seat bottom. Lined with energy absorbing foam, comfort and safety go hand in hand. A tailored infant support cushion and a cup holder are included.
- Extended rear-facing - The radian® 3rX keeps children comfortably rear-facing from 5-45 pounds (2.2-20.4 kgs) for the safest possible position. Premium, plush head and body support cushions are included for newborns and infants.
- Room to grow - Accommodates forward-facing children up to 65 pounds (29.5 kgs) in a 5-point harness and converts to booster mode for kids 50-120 pounds (22.7-54.5 kgs). The aluminum reinforced, adjustable head support and sidewalls provide additional side impact protection.
- Worth the Weight - Our convertible car seats are made from steel for safety you can feel. The fully integrated steel frame is wrapped in thick engineered plastic to withstand severe crash forces. Aluminum reinforced sidewalls provide excellent side impact protection, while energy absorbing EPS foam surrounds your child for ultimate safety. Diono car seats are definitely worth the weight..
- 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.
- 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.
- Side Impact Protection - We’ve got your child’s safety covered. Radian® 3rX 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.
- 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.
