  • 5 to 85 lbs. weight range
  • Snap off pad for easy washing
  • Use rear or front facing
  • Space-saving design
  • Air Protect side impact protection


The Pria 85 Max by Maxi Cosi is a convertible car seat made for cushy comfort that accommodates children all the way from 5 to 85 pounds. It’s designed to make it easier to get your child in and out of the seat and to fit better in your car, allowing more room for passengers to stretch out in the front seats. This feature means it also works well in airplane seats when you’re traveling, too.

Your child can ride rear facing from 5 to 40 pounds, and forward facing from 22 to 85 pounds. A removable insert makes the seat snug for smaller babies. All stages benefit from the Air Protect side impact protection that shields your baby’s head from injury in case of a crash.

This seat is similar to the Pria 85, but has a wider weight range, starting at 5 pounds instead of the Pria 85’s 14. Both are the only convertible car seats rated to 85 pounds, and that extended weight range means you can keep your child safely harnessed longer or accommodate children on the high end of the growth curve. (The reality is that not many children will still be using a convertible car seat by the time they weigh that much—usually they outgrow the seat in height or age before they do in weight.)

It has a magnetic chest clip that opens easily with just one hand and locks on its own when you’re getting your child into the seat. Harness holders keep straps out of the way when you’re loading up, and the lower buckle has a flip-away design that keeps it from getting stuck under your baby.

The seat pad unsnaps and removes easily over the frame, which means it’s super easy to take it off without removing the seat from the car to machine wash and dry. These features make it miles easier to keep the Pria 85 Max clean compared to other car seats, where removing the cover is much more difficult and it has to be spot cleaned or air-dried.

The Pria 85 Max has several design details that make installation and adjustment less of a hassle. There’s a one-click LATCH system for easy installation, and deep rear-facing adjustment makes it easier and faster to correctly install the seat in the rear-facing position.

Very comfy - super cushy and plush - and I love the no rethread on the straps. Strap holders and the flip away buckle are nice touches too since they used to get totally tangled in my infant carseat. I do wish it had replacement covers like the Pria 85 regular. The magnetic chest clip seems cool, but confusing if you're not used to it.
