Your child’s security is Diono's top priority. The Radian 3R was engineered 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.
Some say three’s a crowd. We say, the more the merrier! The radian® 3R car seats fit 3-across in most mid-size vehicles.
The radian® 3R keeps children comfortably rear-facing from 5-40 pounds for the safest possible position.
Room to grow
Accommodates forward-facing children up to 65 pounds in a 5-point harness and converts to booster mode for kids 50-100 pounds. The aluminum reinforced, adjustable head support and sidewalls provide additional side impact protection.
Worth the Weight
Diono's 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. Deep, 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.
- Joy of the journey: From birth, keep your little one rear-facing longer to 40 lbs, traveling safely. As they grow to 100 lbs (10 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 r 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® 3 r 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® 3 r has bright soft fabric covers and a memory foam seat bottom. Lined with energy absorbing foam, comfort and safety go hand in hand.
- Made of Seattle: We are from Seattle, a city where being different is the norm and so is the radian® 3 rX. It folds flat, so you can travel the world and is FAA approved for use on an aircraft. You don’t need to change your plans just because baby is in tow.
