5-star safety. Thoughtful design.
Serious safety and comfort. Our radian® r120 convertible car seat has a full steel frame and aluminum reinforced sides to maximize protection. The slim, all-in-one design works rear-facing, forward-facing and as a booster fitting kids from 5-120 pounds.
Some say three’s a crowd. We say, the more the merrier! Radian® r120 car seats fit 3-across in most mid-size vehicles.
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. 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.
The radian® r120 keeps children comfortably rear-facing from 5-45 pounds for the safest possible position. Premium, plush head and body support cushions are included for newborns and infants.

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® r120 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.
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.
“Absolutely love this car seat. Did lots of research. Wanted a solid, 5-point harness and a steel frame. I definitely feel like both of my babies are protected and safe. I highly, highly recommend this car seat.”
