Meet radian rXT

Don’t sacrifice safety for fit
At just 17 inches wide, radian rXT provides enhanced side impact protection with aluminum reinforced side walls and reinforced, adjustable head support while saving 1-4 inches vs. some leading competitors. An inch here or there might not sound like a lot, but it could make the difference between a secure 3 across installation or failure to fit all the seats your precious cargo needs.

Family friendly, award-winning all-in-one seat.
Radian rXT is consistently rated among the top narrow car seats & recommended seats for multiples by BabyCenter, Babylist, Mommyhood 101 and Babble. Slim profile convertible car seats help parents maximize usage by transitioning from rear to forward facing with ease and stretching a single investment over a 10 year product lifespan.

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