About the Radian 65SL Car Seat

Have kids? Travel often? The Radian 65SL car seat by Sunshine Kids is an absolute must. It’s a super-strong, easy-to-use car seat that actually folds up flat, to a mere 6.5” depth. You can tote it through the airport in its Travel Bag (sold separately), stow it in your trunk, or even slide it under a bed.


And it’s strong. The Radian is the only car seat constructed from a steel alloy frame. Additionally, the Radian positions your child’s center of gravity as low and as far back as possible on the vehicle’s seat, giving it extra stability.


The Radian 65SL is an updated version of the popular Radian 65 Convertible Car Seat.  It incorporates Sunshine Kids' SuperLATCH™ technology that allows the car seat to remain installed with the specially designed LATCH connectors until your child reaches 65 pounds. This is a tremendous innovation, as most car seats can only safely be installed with LATCH if the child is 48 pounds or less.


The Radian 65SL accommodates children weighing 5 to 40 pounds in the rear-facing position, and children over one-year-old, weighing up to 65 pounds and measuring up to 53” tall, in the forward-facing position. The five-point harness has five slots for the shoulder straps and three slots at the crotch. There’s EPS foam at the head, torso, and seating area, which provides extra padding in case of impact. It’s a plus for comfort too. The seat includes a V-shaped tether for the rear-facing position (this is not the case for many other seats), a patented Lock-Tite harness clip, and it is LATCH equipped.


In fact, its outer shell is surprisingly narrow, despite a roomy seating area. This allows you to fit three car seats across most back seats, or install it in the center seat, leaving room for passengers on either side. Installation is easy and is aircraft approved. Ciao, baby.


Spilling the beans: The seat weighs in on the heavy side at 20 pounds, due to its steel frame. But since it folds flat, it’s better to think of it as just another piece of luggage.

Note: Installing a car seat base is not a skill that comes naturally. Please visit a certified inspection station to learn about proper installation and to verify that your base is installed securely and correctly.

A great seat


Easy to Adjust, Comfortable, Easy to install, Stylish, Safe, Sturdy


Large when rear facing

I just transferred my large 4 month old into his Radian 65SL. It's so roomy and comfortable for him. The Radian is easy to install and the included directions are clear and concise. It has a small footprint, meaning we can still pack the car or fit passengers in the back seat!


The only drawback I see is using the Radian rear facing in a compact car. I have it installed behind the passenger seat of my Toyota Corolla, and my husband can't sit in the passenger seat anymore. Overall, I suggest this seat, especially if you have a bigger car, or you're only using it forward facing.

Yes, I would recommend this to a friend.
