Finding the perfect infant car seat is a daunting task. Finding the perfect toddler car seat 30 pounds later is an even greater feat. And if that’s not enough, a few years and hundreds of dollars later, you have to set out in search of yet another seat: the booster. Wouldn’t it be great if you could have all three in one perfectly safe, comfortable and stylish design? With the Diono Radian RXT, you can!

  1. Wow… one of the awesome features of this car seat is it’s AWESOME rear facing capabilities. It is VERY disappointing to see such a young child forward facing for this feature. Why would you not want to be the ultimate example for your readers of great safety? This is highly disappointing.

    • I absolutely agree with you, Ana! Diono is an amazing seat for ERF.

      This is how the photoshoot worked out, as it is usually easier to take photos of the seat in the front facing position depending on the car.

      However, we absolutely recommend rear facing for as long as possible. In fact we will be featuring Diono seats in some of our upcoming travel/roadtrip posts and the focus is going to be specifically on Extended rear facing.

      • I would disclose that at the beginning of the article then. I understand it’s easier to photograph forward facing, but you should be the ultimate example of extended rear facing for your readers if that is what you are advocating.

        • The child in the feature is 2.5 which isn’t a young age to be forward facing. However, yes we all do recommend rear facing till they outgrow the seat or the situation dictates forward facing otherwise.

  2. Totally agree about the rear-facing thing. That kid, if indeed 2.5, is tiny for his age and really should be RFing (Car Seats for the Littles, for example, one of the top sites for car seat safety, recommends rear-facing until as close to four as possible as long as the child safely fits the RFing seat, which there is room for in spades here). I’d absolutely like to see a disclaimer at the beginning of this article advising as such. It would have been nice to see some pics of it rear-facing so those of us considering it could see how it looks and fits the child in that configuration.

    • We have a travel feature coming up with some new Diono seats in rear facing position, and while it won’t be a dedicated review, you will see lots of pictures.
      Will definitely take a disclosure under advisement. Thank you, Lara!
