Background on Diono

When was the company started?

Diono is a relatively new American company that was founded in 1999. It was founded by Brad Keller, and the headquarters are currently located in summer, Washington. The Diono mission is to create state-of-the-art baby products that’ll keep your child safe, secure, and comfortable in every car ride.

How large is the company?

source

Diono has several locations in the US United Kingdom, China, Canada, France, Germany, and Hong Kong and has products in over 54 countries. Their estimated annual revenue is $26.5 million with over 70 employees working at each location.

What products does the company manufacture?

Diono manufactures a steady line of car seats (all-in-one convertibles, infants, and boosters), strollers, baby carriers, and accessories.

What is the reputation of the company’s products?

Diono is known for its high-quality car seats that provide enhanced protection for years to come. They’re not only strong, but they’re also certified for airplane use, which is a quality that most car seats don’t have. Diono car seats are also known to have a higher rear-facing limit and expandable leg rests to give your child plenty of legroom. Lastly, Diono is famous for integrating most of its car seats with a 3-across-fit feature that leaves plenty of space for your other passengers.

Difference between Diono Convertible Car Seats

The biggest difference between the Diono all-in-one’s and the Diono convertible car seats is that the all-in-one’s come with a 3-across-fit feature. This feature means that you can fit three of these seats in your car without worrying about it too cramped. It also means that if you have other passengers riding with you, they won’t be confined to a little space due to a bulky car seat.

Diono Convertible Car Seats vs Other Manufacturers

Diono vs Britax convertible car seats

Diono

VS

Diono Car Seat

Britax Car Seat

As far as price, Diono and Britax cost about the same. There are some Diono models that may be on the pricier side but in general, one brand is not too much more expensive than the other.

Britax does have a bit of the upper hand when it comes to their safety ratings and reputation. That’s probably due to them being around a lot longer (+70 years), so they’ve had time to build and create new products that exceed the NHTSA safety standards. But, Diono is definitely catching up.

While both brands have some sort of ClickTight or SuperLATCH installation system, Diono is the only one with a compact design that frees up more space in the backseat. Diono convertible car seats can also be adjusted to give your child more legroom and more time in the rear-racing position.

Diono vs Clek Fllo convertible car seats

Diono

VS

Diono Car Seat

Clek Fllo Car Seat

Clek Fllo convertible car seats are a bit more practical to use. They’re very compact and lightweight, which makes it easy to sit more than one of them in the back seat, much like the Diono 3-across-fit feature.

In regards to price, both brands are in the same ballpark, however, Clek Fllo may be a little bit cheaper. Also, Clek Fllo convertible car seats come with an anti-rebound bar to minimize the impact force of a car crash, and Diono car seats don’t have this option.

Lastly, Diono car seats are known to be easier to carry and travel with than Clek Fllo car seats. On the other hand, Clek Fllo car seats have a slightly better safety rating than Diono car seats.

Diono vs Graco convertible car seats

Diono

VS

Graco

Diono Car Seat

Graco Car Seat

First, all Graco convertible car seats are equipped with cup holders to make carrying your child’s drink easier and more convenient. Also, Graco car seats are bulkier than Diono convertibles, meaning they don’t the ability to free up more space in the back seat as Diono car seats do.

As far as price goes, Graco car seats are definitely cheaper than Diono. That doesn’t mean they’re lacking in quality. Both brands are equipped with state-of-the-art features to ensure that your child is getting the safest car ride every time.

Safety ratings for both brands are about the same, but Diono car seats are certified for airplane use and can fold up easily, making travel so much easier.
