Get the car seat that’s designed with your family’s real life in mind. The Cosco MightyFit™ 65 DX Convertible Car Seat keeps your child safer in the car all the way from 5-65 pounds. It’ll keep your baby comfortably rear facing up to 40 pounds, and then transitions to forward-facing mode up to 65 pounds.

Not too big and not too small, the MightyFit 65 DX is designed to be the right size. In rear-facing mode, it takes up less room, which gives parents more leg room in the front seats. The car seat will also fit three across the back seat of most vehicles, which is great for growing families.

MightyFit 65 DX keeps kids safer with Side Impact Protection built right in, and a 5-point harness that adjusts easily from the front of the seat. The harness features 5 heights and 3 buckle locations so you can be sure you’re giving the best fit to your growing child.

The MightyFit 65 DX Convertible Car Seat is mighty comfortable for kids and convenient for parents too. Kids will love the plush padding and deluxe materials that give them an extra comfy ride. You'll love that the fabric is both machine washable and dryer safe, making this seat super easy to clean when messes happen.

If your chosen vehicle happens to be an airplane, this convertible car seat has got you covered. Certified for use on aircraft, it gives your child a familiar seat during the flight. Its compact design also makes it easier to manage through airport security checks.
