What to Consider Before Purchasing a Baby Car Seat

​​​​​​​It’s essential to keep a few things in mind when choosing the right car seat for your child. If you wish to learn more things to consider before purchasing a car seat for your kiddo, read our guide to select the best baby car seats.


You should think about how long you intend to use the car seat. If you are financially buoyant enough, start with an infant car seat. It is most suitable for newborns, but they can’t use it for long because of the short weight limit. You will still need to get a convertible car seat at some point. If you are on a budget, you can buy a convertible seat right away as it can last you till your baby becomes a toddler and a young child.

Car Space

Measure your car space before ordering a car seat to ensure that you are buying a seat larger to smaller than your car. The car seat must perfectly match your vehicle to prevent future accidents that put your child in danger.

Safety and Security

You have the responsibility to keep your child safe when riding in a vehicle as a parent.

Car accidents cause the deaths or injuries of thousands of young children every year. The right car seat is an integral part of keeping children safe in the car. In addition, make sure the car seat of your choice passed UNR 129-Size and the ECE R44 regulation tests to guarantee your infant’s safety.


Do you want a car seat that can grow with your kid and save you cost in the long run? Then a convertible car is a perfect choice!

You can never predict how kids will act, but one thing is for sure – they grow up fast! The moment you get used to the forward-facing seat, boom! They need a booster! Fortunately, Diono Monterey XT Latch has your back if you don’t have a convertible with booster mode.

Diono Everett NXT

Diono Everett NXT

With the Diono Everett, you can place the child’s headrest in seven different ways for maximum comfort. It includes a fabric cover that is padded and plush.

If something unexpected happens, the cover will absorb the liquid, and a parent will be able to remove it quickly.  After you have washed the material in your washing machine, slipping it back into the seat is a piece of cake.

Moreover, in an accident, the foam provides your child with protection because it is made out of a shock-absorbing material. The lightweight aluminum used in the frame further ensures this protection by preventing side impact damage as much as possible.

Diono Everett also has a slim-fit design that provides more improved support, comfort and safety for kids, especially the petite ones.

The LATCH feature lets you know that your car seat is securely fastened by listening to the click that indicates your seatbelt has been appropriately attached.

The seat’s back is narrow to provide easier access to your vehicle buckles

Another exciting feature about Diono Everett is the fact that it is lightweight. This is not a shared experience with convertible car seats. Thankfully, its lightweight and foldable quality allow you to move the car seat between vehicles quickly.

Diono Radian 3R

Diono Car Seat Radian 3R

We have the Radian 3R from Diono, another slim-fit version of this seat, but this one was intentionally designed to make transitions between modes as easy as possible. Radian slim-fit convertibles offer maximum comfort for children and passengers while fitting in most vehicles.

Due to its original Slim-Fit design, it’s pretty convenient for carpooling since it fits three across the back seat, and with its foldable design, it’s suitable for travelling as well.

Radian 3R has been designed to allow your child to remain rear-facing for even longer, up to 50 pounds.

Also, with the high-back booster feature, your child can enjoy extra safety and comfort, which can last till he exceeds the booster mode’s maximum recommended 120 pound-weight.

A reinforced steel core in the Diono Radian 3R makes it incredibly stable and sturdy, just like the previous Diono model.

In addition, the sides are reinforced with aluminum and filled with energy-absorbing foam for excellent side impact protection.

Using the Super Latch system ensures real security with minimum effort. Once the audible click occurs, your child is safe.

There are a few handy additions, including anti-slip harness pads and memory foam padding, that make a huge difference in the overall comfort level for your child.

When things get messy with kids so quickly, it will be convenient to have removable covers to clean in the washing machine and put back on.

Like other Diono convertible car seats, this model grows with your little one and can last for about 10 years or more with its rear-facing, front-facing and booster mode.

Diono Solana 2

Diono Solana 2 Latch

You don’t have to get a pillow for your child to sit on while in your car, as Solana 2 backless booster can handle that while providing safety.

Diono Solana 2 specializes in elevating your young man in your vehicle so that your car seat belt can comfortably fit, hold and secure him.

Your child can enjoy maximum comfort and stay safe as it can hold children’s weight up to 120 pounds. While the Solana 2 car seat offers maximum safety and security, its integrated LATCH connectors and front adjusters make it easy to connect and install.

Booster car seats with no backs are incredibly convenient for carpooling, and frequent vehicle changes. Space is not an issue with these seats because they are so portable.

Diono Solana is exceptionally efficient because it has the same bottom-weight limit as the high-back booster, which is not very common. And of course, it does not cost as much.

With extra length for better leg support and an ergonomically contoured seat, this booster seat is ideal for those who want to avoid slipping. It is, therefore, similar to the high-back boosters.

This backless booster has a portable and lightweight design, making it easy for you to transfer from one vehicle to another.

Also featuring two cup holders and a removable, machine washable cover, you don’t have to bother seeing stains on the Diono car seat.
