Super pleased with the Radian!
We purchased two Radians. In the past, we have used Britax convertible seats; I have much older kids and have had Boulevards and Marathons, and we currently have two Marathons in our other car. We needed something with a higher rear-facing weight for our beast child, and the Radians have been reviewed so well (both professionally and by friends). We were trying to choose between this and the Clek Foonf for back-to-front space and a higher weight limit, and these were smaller. We have not been let down.
They are easy to install. They are narrow. They don’t take up as much room front-to-back (but buy the wedge/positioner if you have a rear facing kiddo). The thing that impressed me the MOST is that these seats feel truly comfortable.
I like the solid, darker colors because they don’t show dirt or stains like many other seats I’ve had. I’m a sucker for bright colors and fun patterns, so this isn’t something I thought I would like, but I do.
No complaints. Be warned, though: This seat is heavy. I cannot emphasize that enough. If you are someone who has to move seats a lot or, more importantly, if you need to have a car seat that you use frequently for air travel, this may not be the right choice for you.
Otherwise, it’s a great car seat.
