Travel The World
Super portable, folds flat with available carry straps for easy travel and transporting with ease.
The 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.
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. A tailored infant support cushion and a cup holder are included.
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 the baby is in tow.
