Here are the 6 Best Diono car seats (convertible seats) reviews for 2022!
Diono is one of the top leading brands in convertible infant car seats. Here is a review of the 6 best Diono car seats and convertible seats, along with my number one choice of the best seat for the price.
Convertible car seats are becoming more popular among parents. They have a larger range of height and weight limits. Many of them start in a rear-facing position but can later be transitioned to forward-facing. The convertible seat also sports booster mode. This allows parents to only need to purchase one car seat for the entire time their child is in need of one.
In fact, Diono’s trademark is “10 years, one car seat.” The convenience of this is great for any parent, but the main reason I like Diono car seat manufacturers is their safety features. Even the most basic Diono all-in-one car seat comes with a steel core (or steel alloy frame) which helps protect your child in the event of a crash. Some of their car seats come with additional safety features that protect in the event of an accident which I will highlight below. These car sear manufacturers are on the path to making the perfect car seat.
I set out on a quest to find the best Diono car seat that had great car seat safety as well as a great car seat review. Though Diono also offers many booster seats, this article will focus on their car seats. But just in case you would like to know what my favorite booster seat is, I’ll include that info at the bottom. I’m reviewing their top 6 convertible car seats and then will pick my favorite based on features for the price.
For an easy-to-view comparison chart of all the features, see below.
Ease of Use for Diono Car Seats
All of these Diono seats have a superlatch system that is easy to use, extended rear-facing use (see below), and easy cleaning. Other notable features are that the covers to the car seats are machine washable, Simply throw it in the washing machine and lay it flat to dry. The shell of the car seat is spot clean only. These are also the only car seat I have found that has a slim fit design, meaning if you need three in your back seat at one time, that’s completely doable!
Extended Rear-Facing use is important considering that the AAP (American Academy of Pediatrics) recommends that babies stay rear-facing in their car seats until two years of age. This can be tough to accomplish with a standard car seat, but the Diono brand is making it easier for parents to accomplish.
You can purchase any of these seats at Diono’s website, but I noticed that Amazon actually offers them for less, so unless there is a promotion happening from Diono, Amazon may be your best bet for the best price.

Alright, the verdict is in. After tons of research on all of the great stuff Diono has to offer, I have picked my favorite overall Diono Car Seat. This is only my opinion and different things work for different families. But based on safety features, design, and price, the best Diono Car Seat in my opinion is the Diono Radian 3RXT. It comes with great safety features and the 12-point adjustable headrest that is vital for my kids as they grow. It helps them sleep better when traveling. Plus, I like the color options. Personally, I don’t feel the need for extra cup holders or an infant leg rest.
The Best Diono Booster Seat

It also has a six-position, easy-to-adjust headrest. The price is fair at around $100 and it comes in 3 color options. See it here.
