Product Description

Enjoy peace of mind with the latest innovation in child passenger safety, the Maxi-Cosi Pria 70 Air Car Seat.

Experts agree that the safest car seat is the one that fits your car, fits your child and will be used correctly every time. The specially designed TinyFit system allows the Pria 70 to remain upright while in a rear-facing position. This seat within a seat design creates a snug harness for tiny occupants, with low shoulder slots and a comfortable reclined position. The Pria 70 is designed to fit where other convertible car seats do not. The unique design of the Pria 70 requires less space in the vehicle, giving more room for the front seat passengers, and an easier installation. As the child grows, the TinyFit system is removed, creating a comfortable forward facing riding position for children all the way up to 70 pounds. Advanced safety features, like Air Protect and FlexTech energy management, provide superior protection in both forward-facing and rear-facing modes.

When it comes to car seats, a superior fit is superior safety. Enjoy peace of mind with the Pria 70.

Comments about Cosco Inc Maxi-Cosi Pria 70 Convertible Car Seat with Tiny Fit - Walnut Brown:

We were search for a small car seat for our Toyota Access Cab (Tacoma 2005) and a mini cooper. This was too big for both, but the grandparents kept it for their car! What a lovely looking carseat, with so much support. The tiny fit insert is great, and means this carseat will take us from birth on up to when our baby is a big kid and outgrows car seats! Loved the color options.

Comments about Cosco Inc Maxi-Cosi Pria 70 Convertible Car Seat with Tiny Fit - Walnut Brown:

This is a wonderful car seat! My son is 5 months old and is too long for his bucket seat. I was looking for a safe, comfortable, size appropriate, and something that would fit in my 4 door car. This is an awesome seat. I'm very satisfied that my child is very secure and safe and comfortable in this seat. It tilts easily and adjust with 1 hand. It looks bulky but fits with ease in my car. The padding around the 5 point buckle is fabulous! I'm buying a second for my other vehicle!
