Diono Radian 3RXT- Best Slim Car Seat
Are you looking forward to investing in a long-term slim car seat? Diono Radian 3RXT is your best bet as it fits in multiple small cars 3 across due to its 17 inches width and will stay in the family for almost 10 years.
Use it for your newborn from his 5 pounds till he turns 50 pounds in the rear-facing. Compared to other car seats, it offers 4 years of rear-facing mode or until your baby touches 44 inches in height.
It has a high wedge that gives your baby’s back additional comfort. This wedge is removable once your baby is past the newborn stage. One of the best parts that makes it reliable is the steel frame that soaks the impact and protects your baby in case of an accident.
If you still want to add a layer of protection to the safety system of your baby, you can buy Diono Ultra Mat Pack. The car seat is so easy to install and remove. However, you can take the help of videos online to figure out the process.
What sets it apart from Radian 3R are the head positions and cup holder. The car seat has to offer 12 adjustable headrest positions so the little one rest peacefully. In contrast, the cup holder holds your baby’s drink to prevent spills.
After 50 pounds of your baby, you can face the car seat forward. Its 12 inches, shoulder, and hip width are sufficient to nestle your growing baby. The depth of 16 inches and breathable fabric is also why babies nap in this car seat for long hours.
On its downside are the weight of the car seat and armrest. To keep the width less than others, Radian 3RXT lacks an armrest. At 28.1 pounds, it is the heaviest unit, so moving it from one car to another can be challenging.
Chicco KeyFit 30 Slim Infant Car Seat

Equipped with a LATCH system, it is so simple to snug fit on the base. While the base is plastic, and the housing is rated great for safety. It has side impact protection and a head and body insert to ensure your infant stays sound during a crash.
It is 17 inches in width, so that goes without saying, it fits in a small car, leaving space for two more car seats to fit adjacent.
Made for babies from 4 to 30 pounds or 30 inches in height, it limits car seat usage. However, that’s not a big deal if you are planning to have a convertible or booster car seat in the near future.
At 16.6 pounds, the car seat is easy to shift between cars. So, it’ll be easy for you to get it fastened in your husband’s car. And, let us mention that it weighs just 9 pounds without the base.
Two of its incredible features are the removable canopy and seat padding. The seat padding is machine washable, minimizing your house chores that multiply with a baby to feed.
