1. Diono Radian RXT All-in-One Convertible Car Seat
Let’s go straight to the first model in our list of the best convertible car seat for small car: Diono Radian RXT. You probably have heard a lot about the brand. Diono’s car seats are known for their slim designs; they are often chosen by people who need to install three car seats across. Diono Radian RXT is especially great because it can be used for a very long time.

It has a slim and compact design. It measures only 16 inches x 17 inches x 28.5 inches. So, it can easily fit inside a small car. When in the rear-facing position, the tall back may require a significant amount of space; however, you can purchase the optional angle adjuster in order to free up some space if your car is really narrow. The angle adjuster is not an obligatory safety piece, but the accessory is inexpensive.

Furthermore, Diono Radian RXT can fold into a flat form when not needed. This is very convenient. However, despite the size, Diono Radian RXT is actually pretty heavy, so it is not really recommended for traveling. It comes with the SuperLATCH system for easy yet secure installation. It has a rubber bottom which prevents the seat from sliding or slipping.

The build quality is exceptional. It has a highly durable steel frame which is wrapped in thick plastic to withstand severe crash forces. It also has aluminum-reinforced sidewalls and energy-absorbing EPS foam pads for side impact protection. The seat is very comfy, and the harness system is easily adjustable with 12 headrest positions.

Diono Radian RXT can remain in service for a long time. It can be used as a rear-facing car seat (for a child between 5 – 45 lbs), forward-facing car seat (for a child between 20 – 65 lbs), and belt-positioning booster seat (for a child between 50 – 120 lbs). The tall back should be able to fit your child for a long time, but make sure that your child’s head is at least one inch below the top of the headrest.

Pros of Diono Radian RXT:
– Slim, compact, and foldable
– Allows you to fit three units across
– Can convert into a belt-positioning booster
– Excellent build quality and durability
– Easily adjustable headrest and harness

Cons of Diono Radian RXT:
– Quite expensive
– The rear-facing position may require an angle adjuster

2. Combi Coccoro Compact Convertible Car Seat
This car seat is not only stylish, but also exceptionally compact. It is a design done well, and it also provides excellent protection and safety for your child. So, Combi Coccoro is definitely one model that you should consider for the best convertible car seat for small car.

Combi Coccoro measures only 15.5 inches wide and 26 inches tall. In addition, it is also fairly lightweight at about 15 lbs.

So, you can easily fit it inside your small car, and you can even easily set up three units in the same row.

The measurement from the front to the back is surprisingly small, too. As the effect, you can install it in a rear-facing position without having to pull the front seat up. This is incredibly convenient.

Combi Coccoro comes with the Tru-Safe Side Impact Protection technology. It features deep side walls with thick energy-absorbing foam to redirect crash forces away from your child. It has a removable infant car seat to provide the best fit and comfort to your child. Plus, it is FAA-certified, so you can use it to secure your child when going on an airplane flight.

You don’t need to worry about dust, bread crumbs, and spills, because the seat cover is removable and machine-washable. Unfortunately, the height and weight limits aren’t very high. Combi Coccoro is suitable for a child between 3 – 33 lbs in the rear facing position, 20 – 40 lbs in the forward-facing position. The maximum height limit is 40 inches. Combi Coccoro can fit most babies just fine except the tall ones.
