Families who chose Diono

The folks over at Diono work hard to keep our children safe while traveling… What can be safer than a full steel frame and aluminum reinforced sides specifically for unmatched safety?? Even though the Diono Radian RXT is a bit on the heavy side, it assures great stability for a smoother ride with less shaking and wobbling.

For those of you in the market for a car seat that will grow with your child, spend the money. Save a life. I will recommend these seats until the day I die. Especially for those of you with more than two kids... Just bite the bullet and spend the money on a Diono radian rXT. I promise it will be the safest decision you could ever make for your kids.

Heavy is Good

We get it. Really, we do… Hauling kids, bags, groceries. Stuff gets heavy. Mommy muscles are great and all, but do you really want a heavy car seat?

In a word, yes.

Diono radian rXT all-in-one convertible car seat is made with a full steel frame and aluminum reinforced side walls. Energy absorbing EPS foam and reinforced, adjustable head supports are lovingly engineered to keep your little one safe. The fully integrated steel frame is riveted together with thicker engineered plastic, rather than blow-molded plastic, to withstand severe crash forces. The rigidity of the frame enables the car seat to stay intact during a crash.


What Other Parents Have to Say...

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!


As a mother to five children, I can’t stress how much I love these seats. Our daughter is 10 and, while she is technically old enough to be strapped in by a seat belt only, she is still in a 5 point harness! While she is on the shorter side and will be on to the booster mode soon, I love the relief I’ve had knowing she was kept in the safest harness for such a long time.
