How do you feel about the Radian 80SL? I ordered it a couple of days ago and am wondering if I should have spent $30 more on the XTSL? Same weight limits and dimensions — the only difference seems to be the side impact wings…


I have two Radian’s LOVE THEM! I really loved reading the chart on their site here:

Quick note on the LATCH weight limit stuff: Per the instruction Manual you can use the Super Latch on cars 2005 and newer. Before 2005 they state you should follow your car’s instructions manual. More info from there here:

I wish you’d have shown one of the seats rear-facing. If you have 3 kids in car seats, it’s highly likely that at least one of them should be rear-facing, especially now that the aap recommends rear-facing to a minimum of age 2 and nhtsa recommends rear-facing through age 3.

We registered for this seat. Our son was born on 7/9 weighing 9lb5oz. He LOVES this seat! (we drive A LOT!! He easily has about 750 miles under his belt in two weeks) Once buckled in, he immediately falls asleep. It’s a heavy seat, but solid. He’s much more secure in this seat, and cozy, than in his Graco SnugRide. He rode in that once so far b/c we were going to dinner and I wanted him in the carrier so we could eat…only time he’s fussed in the car. We got the best install (with a certified installer) using… Read more »

Totally agree with your assessment of the Sunshine Kids. My only issue with it is the weight. It is SO darn heavy, that on the occasion that I do have to remove it from the car, I dread doing it!


I wish I knew this back in March 🙁 we ended up trading our truck for an suv with 3rd row seating. We are looking into a new carseat though so I will put this on my list so it may be easier if we have to use a different car at some point.

Thank you!!

We use two of these in our small SUV for my 4-year-old twins. We love them and love the fact that they allowed us to use the infant carrier with base when my 14 month old was a baby where none of the other car seats would fit and still allow room to clip the infant seat in and out. We have one installed in the center with the seatbelt (no latch connectors in the center only on outboard seats) and I will say that it is VERY difficult to get installed tightly on our leather buckets seats and we… Read more »

And to add to Patricia’s comment… Remember not to use the two inner of the outboard LATCH’s for the infant carrier/convertible car seat to be place in the center of the back seat. The lower LATCH’s are meant to work together on each side of the car in the event of an accident. Using one from each side to place the car seat in the center defeats that purpose and makes the car seat and placement unsafe for baby. I actually read once that it has the possibility to rip the car seat in half. So be safe with that… Read more »

Also, most cars(and my truck) only have the lower LATCH for the two outboard positions. Which means you can either use it for those two, or just the center one, but not all three, as they are not designed to “share” the latch hooks.


Make sure to check your Auto manufacturer’s owners manual. Even though the carseat says up to 80 lbs for latch the auto latches may not be rated beyond 45 lbs.!
