Baby in a carrier

With so many baby brands out there, you may sometimes ask which ones are good and which ones should you avoid? I know I did and still do whenever I’m buying something for my daughter or to make parenting easier. When it came to reviewing car seats between the Diono vs Britax vs Clek brands, I also discovered a whole lot more about them.

I feel more confident buying from a brand when I know more about them. I think this applies to all parents. So, I’m sharing all I know about these three baby brands because I want you to feel confident when you decide to buy from one of them.

And, FYI – I picked the Diono Radian 3RXT 4-in-1 Convertible Seat as the best car seat out of the three brands. It offers flexibility, safety, comfort and can be used from newborn to 10 years.

Diono – Who Are They and What Are Their Products?

Diono started in 1999 when they introduced the Mighty-Tite, a solution to tightening seat belts. Inspired to improve their products, they became more innovative while relying on their extensive knowledge and skills on car-seat safety. Their passion for helping parents give their kids the best safety while traveling in cars, Diono engineered and developed the Radian range, the first folding steel framed car seat.

But Diono hasn’t stopped at producing some of the safest car seats on the market. They’ve expanded out into manufacturing strollers and baby carriers. To do all of this they rely on a team of designers, engineers and marketers who have many years of experience, skill and knowledge shared between them.

Some parents may not be too familiar with the Clek brand. This proudly Canadian brand came about when its founders searched for the safest car seats for their own children. Based on their research, they realized they wanted to develop better and safer car seats with added convenience and style. Clek – What to Know About This Brand and Their Products

Combined with their automotive industry background and knowledge, Clek explored how other countries were designing their car seats. Europe uses anti rebound features and rigid-UAS systems while Sweden encourages rear seat facing until your child is four years old.

The result? A Clek car seat that includes all of the above features plus metal infrastructures that vehicle car seats use as part of the vehicle’s crash management system. Clek focuses on producing a car seat that uses an all-round, advanced safer technology. Which also means Clek ONLY manufactures car seats.

While Diono’s infant seat Nuna Pipa range is good, I opted for the Radian 3RXT 4-in-1 Convertible Seat simply because it grows with your newborn to up to 10 years old. And, if you’ve got more than one child traveling in the car, the Radian fits comfortably three across in most vehicles.

The newborn travel wedge allows for positioning your newborn in recline. And, when they outgrow the wedge, you simply remove it.

Diono vs Britax vs Clek Booster Seats

Booster seats are wonderful for when your child is older and out of toddlerhood. Many experts do suggest you don’t move over to a booster seat until your child is at least 4 years old. They advise you only use a booster seat when your child learns not to fidget with the seat belt and doesn’t tend to slump over when traveling.

Diono vs Britax Travel Systems

Clek doesn’t offer travel systems. However, their infant car seats are compatible with most top brands and their strollers. Both Diono and Britax do offer various travel system options and I’ve reviewed one from each brand.

Diono Quantum 2 3 in 1 Luxury Multi-Mode Stroller

The Quantum 2 series offer a number of options for converting to a travel system with their Nuna Pipa range of infant seats. Plus, this stroller offers various features making it a very user-friendly product. I love the aesthetics of this stroller. It will make any parent and baby feel smart!

The Diono fold system is easy and is power-assisted for a quick unfold. It has a 5-point harness system that grows with your baby. Your baby will be kept comfortable with the layered and padded cushions which are removable for washing.

An adjustable canopy keeps your baby well-protected without getting too stifled. The “one foot” braking system is convenient plus the asymmetrical design ensures the stroller is well-balanced.

How do I decide which brand is right for me?

Research the brand and discover what drives them to produce baby products. Make sure they use high-quality materials and that their products meet stringent safety standards. It may also help to read customer reviews to get a better sense of what other parents, like you, feel about a brand and their products.

What should I look out for when selecting a car seat?

The number one key feature should always be safety. Then, ease of use, comfort, convenience and additional features such as cup holders, lightweight, portability and weight limitations. You may also want to see if the car seat is best suited for your child’s age. And, if you have a smaller car, looking for a slim fit design is useful.

Are booster seats safe?

Experts will tell you high back booster seats are safer than backless booster seats. A high back booster seat gives added protection around the head and neck. But, it’s better to have a backless booster seat than nothing at all.

Final Thoughts

If picking between the Diono vs Britax vs Clek brands became my sole responsibility, I would battle to say which one comes out top. All three brands are serious about child safety and offer the best in high-quality products. I did pick the Diono Radian 3RXT 4-in-1 Convertible Seat because of its versatility. But, I honestly believe you can’t go wrong with any of the products reviewed here.

It all depends on what you want for your baby’s own needs while traveling in the car. I’ve given you all the information you need to know about the brands and their products. Now, it’s up to you to decide which one you would pick.
