About this item

Product details

The Cosco Kids™ Finale 2-in-1 Booster Car Seat may be the last car seat you will ever need! It features extended use in both of its two modes. It starts by keeping toddlers securely in a 5-point safety harness all the way up to 65 pounds. In its second mode, as a belt-positioning booster, it has them covered up to 100 pounds.

In both modes, the Finale Booster Car Seat is lightweight and easy to move from car to car which is excellent for families who are always on the go. It also easily fits 3 across in the back seat of most vehicles making it a smart choice for growing families with multiple kids in car seats at once.

With kids in the car, messes happen. But thanks to the easy-to-clean car seat pad, there’s no need to stress. The pad removes from the seat and is both machine washable and dryer safe, so a thorough wash is just a machine cycle away.

The Finale 2-in-1 Booster Car Seat is proudly made by Cosco Kids™ in Columbus, Indiana.

Lightweight car seat

Very light car seat! Makes it super easy to move in and out of the car. The straps can be a little hard to tighten at times is my only complaint.
