(4.5 / 5)
Initially, the Radian RXT is used rear facing from 5 to 45 pounds. It then converts to front facing complete with 5-point harness suitable for a child of 20 to 80 pounds. Finally, the harness can be removed, and it can be used as a belt-positioning booster suitable for use from 50 to 120 pounds.
This model is constructed using a very strong steel alloy frame together with aluminum reinforced sides. This frame is then generously covered with energy absorbing EPS foam to give wrap round protection to your child in the event of an accident. Memory foam is also used for an extra comfortable ride.
The 5-Point Safestop® Energy-Absorbing Harness System is fully adjustable with 5 shoulder and 3 buckle positions so you can be sure of achieving a good fit. The head support also has 12 different height adjustments, so there is plenty of adjustment for a growing child. The RadianRXT also comes complete with infant body support cushions that can be removed as your child gets bigger. In the forward facing position the seat can be reclined in 2 different settings for added comfort.
Installation can be accomplished by using either the LATCH system up to 80lbs, or your own vehicle safety belts. This is a narrower model than some on the market and it is possible to fit 3 Seats Across on most mid-size cars. So, if you are struggling with seating 3 children then the RadianRXT could be the solution.
This seat can also be folded flat when not being used or for easy transporting.
The manufacturer, Diono, offers a one year limited warranty.
The RadianRXT comes in several different designs including Cobalt, Plum, Shadow and Spring. The covers can be removed for machine washing by following the manufacturer’s comprehensive instructions.
