Cosco Finale DX 2-in-1 Booster Car Seat

With the busy lives we all lead, it can be difficult to find time to shop for the perfect gift for a baby shower or new arrival. This can be especially challenging when you have a toddler who is always clamoring for your attention. The Cosco Finale 2-in-1 Booster Car Seat is an excellent gift for a new baby, new arrival, or a child of any age that’s outgrowing the old car seat. This car seat can be used for children weighing up to 100 pounds. This seat is also compatible with most vehicles and is easy to install. The Cosco Finale DX 2-in-1 Car Seat is available in various colors and patterns to match any car or home décor.

This car seat is versatile and long-lasting. It features extended use in both of its two modes. In the first mode, it safely keeps kids in a 5-point harness up to 65 pounds. In the second mode, it acts as a belt-positioning booster for kids up to 100 pounds. The deluxe fabric provides a comfortable ride for kids in both modes.

Cosco Finale Car Seat Features


The Cosco Finale 2-in-1 Booster Car Seat meets or exceeds all federal safety standards, as well as those set forth by the Juvenile Products Manufacturers Association, and IIHS rates Cosco finale booster seats as the best bet for use in a vehicle. It has a five-point harness that can be used in one of two modes. Also, the LATCH connectors make for a stable installation in the safety-harness mode. Finally, the car seat expiration is 10 years from the manufacture date, which is indicated on the label on the side of the product.


This 2-in-1 combination seat is a great deal because it serves as both a front-facing harness seat and a seat belt booster seat. You won’t have to buy two separate seats, which will save you money in the long run. Its slim shape lets you put three of them in a row in most vehicles, which is perfect for families with several little kids. It’s also really lightweight, so it’s easy to move from car to car as needed.

The fabric can be taken off and put in the washer and dryer, making it easy enough to clean, whether dirt has gathered over time or spills or accidents have happened. Some parents who reviewed this car seat felt that the padding could be thicker, making it more comfortable.


Forward-facing mode with a harness is for children 30-65 pounds and 32-49 inches tall. They must be at least 1 year old. The belt-positioning booster seat mode is for children 40-100 pounds and 43-52 inches tall. The fit may not be accurate for all children. Some children may not be comfortable in the seat within the listed weight and height ranges.
