Just saw the debut of the All New Sunshine Kids Radian XT car seat and it is AWESOME! It does have many similarites to the Radian 80 seat but way cooler. Firstly, in regard to safety. This seat offers TSIP. True Side Impact Protection. The head support is adjustable, and is independent of the harness system which adds additional safety. The head rest has got EPS foam and made with 3 steel rods for maximum safety. The side of the car seat is made out of aluminum for added security. The Radian XT is avialable in 4 cool colors. The Nasa color, the Reo color,(which is a pomegranite color) the Peda color and an onyx type color (Black and grey). The Radian XT offers all the safety you can wish for with out all the bulk. It can fit 3 car seats in a row in the back of a car! Thats Awesome. There are some other really safe seats out there but they are so bulky. The Radian XT Car Seat is actually offers 2 inches more space for the child than the Britax Marathon Convertible Car Seat, Yet it is 3 inches narrower! The Radian XT by Sunshine Kids will also be able to fold just like the popular Radian 80. This seat is now in stock and ready for immediate shipment! So orders yours now!
