Steel Frame and Side Impact Protection
The Radian XTSL Convertible Car Seat is constructed with a steel alloy frame for ultimate safety and strength, providing security for your child and peace of mind for you. The seat's side impact protection features include aluminum-reinforced sides and energy-absorbing EPS foam, which work together to protect the child's head and body and provide a thorough, superior level of protection. The XTSL stands out as the only Radian model to include aluminum reinforced head support with adjustable head wings, which enhances safety and provides support for sleeping children.

For added safety, the seat is also equipped with a forward- and rear-facing tether system and is the only car seat in the market to offer SafeStop technology, an energy-absorbing harness system.

Easy Installation, Portability, and Convenience
Like many car seats, the Radian allows you to easily install it by engaging the seat's Latch connectors onto a vehicle's Latch bars, which can be found in vehicles built after 2001. For drivers of vehicles without Latch, the good news is that the seat can also be easily installed with the vehicle seatbelt. For cars with Latch, the seat's SuperLATCH system is a prominent feature that offers added convenience and increased safety.

What makes the Radian XTSL different? Typical Latch systems have limited weight capacities of 40-48 pounds. Once a child has reached this weight limit, instructions call for the caregiver to unlatch the seat and reinstall it using the car's seatbelt, a method that increases the likelihood of incorrect installations. The XTSL's SuperLATCH system extends that weight limit to 80 pounds. Beyond the added convenience, SuperLATCH also helps increase safety, as a Latch system is an easier installation method with less room for error than using the seatbelt method. Further easing installation is an Easy-Tite adjuster for firm fastening and rubber non-slip grips along the seat bottom to prevent car seat slippage.

Because safety is a priority to Sunshine Kids, the Radian not only meets and exceeds US mandated standards, but has also been tested to the more rigorous, yet voluntary NCAP standard which simulates more severe accidents.

Of particular convenience to daycare providers and parents of multiple children, the Radian's slim design fits three across in most vehicles, making it ideal for sedans and smaller SUVs. Plus, it still provides ample shoulder room for growing children. Yet another unique feature of this car seat, the Radian is the only convertible car seat on the market that folds flat, so you can store it away and take it along for travel. The Radian XTSL also features a handy padded shoulder strap.

Comfort Features for Growing Children
This innovative car seat will grow with your child from infancy to childhood and is designed with several features to ensure your child's comfort, whether you're driving across town to the babysitter's or across the country for the holidays. These comfort features include comfort foam padding, a long seat, adjustable seat positions, and 3-in-1 infant/toddler full body support cushions.

Especially pleasant for those long rides, the memory foam padding around the seat, plush fabric, and extended seat bottom combine for an extra comfortable fit. The forward facing position's dual recline angles give two options that are ideal for going from nap time to an upright position without trouble. Additionally, the five harness positions and three buckle positions make it easier than ever to customize the car seat to ensure your child is properly secured as he or she grows.

And featuring the two highest weight limits in the market, this convertible car seat is suitable in the rear-facing position from 5 to 45 pounds. When children are old enough, they can be positioned in the forward-facing position up to a weight of 80 pounds. And for easy child-boarding, the seat is designed to sit low on the seat.

The car seat is covered with a breathable, polyester air-mesh fabric that comes in grey with black velour trim for fashionable families.

By Rachel Israel on May 19, 2011
I LOVED this seat. I have both a Radian XT and a Radian XTSL and purchased the XTSL in order to keep my son rear facing to 45 lbs. The problem is that the "super latch" is failing in many cars now. Sunshine Kids has been notified of this and there have been more than 100 reports filed with NHTSA; however Sunshine Kids refuses to recall the Super Latch. I can't recommend a seat from a company that dismisses so many car seat technicians installations. Check out you tube for videos of 2 year olds moving the Super Latch with very little force. This seat needs to be least the Super Latch. So many parents out there will not know about this problem without checking (I didn't).

Before buying this seat, I was a loyal Britax customer. Having used Graco and Britax seats, I saw how Britax was far superior and assumed they made the best seats. In hindsight, if I had purchased this Radian sooner, I would have never bothered buying any other carseat. This is literally the perfect seat.
-It has a steel reinforced frame, which is sturdier than any other seat I've seen (I've been on the market for a new seat for months, and have played around with display models of virtually every seat in this class. I was not impressed by any of them).
-It is very comfortable for my child. She is 34 inches and 24lbs and rides comfortably rear facing in the middle of the backseat.
-It rear-faces to 45lbs. My daughter has surpassed the percentile charts for her age and is the size of a child a year older than her. She was too big to rear-face in our Graco ComfortSport by 10 months old. Obviously, I would not put a 10 month old forward facing!
-This seat comfortably support a child from birth, yet accommodates up to 80lbs.
By researching on, I found photos of newborns peacefully riding in this seat, and also photos of 4yr olds still rear-facing with no problem! The 45 degree angle rear-facing is plenty enough recline for a tiny baby.
-The crotch belt has multiple positions to accomodate bigger kids without them having to sit on the strap like in some inferior seats. You can even purchase a longer strap for especially large children.
-Easiest install of any seat I've tried!! In my experience you need an engineering degree to install a Graco seat properly, this Radian took me less than 2 minutes to install rock-solid! The Super Latch is completely fool-proof, extremely easy to adjust and sturdier than your average latch belt.

The Radian XTSL is having quite a few issues with their superLATCH coming loose during use. (You can search for the facebook group or Youtube for more information on this issue). Not only is Radian ignoring the problem and not issuing a recall, but they were extremely rude to me on the phone, talked over me the entire time, and called me a liar. Several people have been told to fix the LATCH with duct tape. Even though the seat is perfectly safe while using the seat belt, I cannot trust this company anymore. To think they are not notifying parents of a serious issue is sickening to me. I sent back my Radian and got a Britax Roundabout 55. Not only is Britax a more trustworthy company, but the seat is so much more secure in our car. Learn from my mistake and don't get involved with this company. I should've known better after the issues with the Mighty Tite severing seat belts. Sunshine Kids didn't issue a recall on that product, either.

I don't normally write reviews, but I felt like I had to write something for this product. This car seat is awesome, and dealing with Sunshine Kids is even better!

I ordered the car seat from Amazon, and it arrived quickly and in great shape. Unfortunately, while I was unpacking it I did not realize that energy-absorbing (EPS/EPP) foam is basically Styrofoam, and I tried to pull out a piece of it that was underneath the seat base. When it snapped and I saw that the rest was glued on, I realized that it was structural to the seat.

I emailed Sunshine Kids to ask what I should do, and even though it was completely my mistake they sent me a new piece of foam with instructions on how to install it. If you're going to drop several hundred dollars on a car seat that you plan to use for 5-6 years, it's very nice to know that you're dealing with a company who will stand by their product and provide excellent customer support.

Great customer service aside, this seat is very nice. The cover is soft and comfortable, and I love how narrow the base is. We have it installed in the center back seat, and an adult can comfortably sit on either side of the carseat, which would definitely not be the case with most of the other convertible seats out there. Best of all, our daughter loves sitting in it. Every time we strapped her into her infant bucket seat (Chicco Keyfit 30) she would cry and try to get out after a few minutes, but she doesn't mind sitting in this seat at all, and we're actually able to drive for more than a few minutes in the car without tears.

As some of the other reviewers have pointed out, this seat is very long, and you may have to push your front seats up quite a bit to get it installed correctly rearfacing.
