Review: Super awesome car seat - After four months, my son is about 16.5 lbs and his infant car seat was getting a little small. We still use them but I wanted something permanent in my car. This wasn’t the easiest to install, as I couldn’t tighten the belt as I wanted to. Since it’s such a big and bulky car seat, the front seat has to sit up really far when the pria 85 is fully reclined. I have a 2017 highlander. As far as comfort, my son has seemed to completely enjoy his car rides now. He’s up higher and has more room. Overall, this is a great car seat if your car is big enough for it and you have help installing it. Review: Excelente! - Tengo un vehículo compacto y la silla queda perfecta, no choca con el asiento de adelante estando reclinada y a contramarcha. Fue fácil instalarla, quedó super justa y no presenta movimiento. No tiene ningún olor raro, ni penetrante o desagradable. Llegó en perfectas condiciones. Volvería a comprar otra sin pensarlo ## Features - ALL-IN-ONE DESIGN: The convertible car seat is designed to support your child as they grow: infant rear-facing (4–40 lbs. and 19"–40"), toddler forward-facing (22–65 lbs. and 29"–49"), and big kid belt-positioning booster (40–100 lbs. and 43"–52"). - QUICK BUCKLING: ClipQuik is our magnetic chest clip on the all-in-1 convertible car seat and belt-positioning booster that you can open 1-handed to make buckling and unbuckling fast and struggle-free. - OUT-OF-THE-WAY HARNESS: The convertible carseat includes an out-of-the-way harness system that helps eliminate fumbling with straps and buckles. - COMFORTABLE PURECOSI FABRICS: Our PureCosi plush fabric, padding, and cushions on these carseats are made without wool or added fire retardant treatments. - EASY INSTALLATION: The 1-click LATCH connectors on the all in one car seat simplify installation, offering a secure and fast setup for your all in one car seat. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09RRWDQWL | | Age Range Description | Kid | | Best Sellers Rank | #65,903 in Baby Products ( See Top 100 in Baby Products ) #60 in Convertible Child Safety Car Seats | | Brand | Maxi-Cosi | | Color | Essential Black | | Colour | Essential Black | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.5 out of 5 stars 1,962 Reviews | | Forward Facing Maximum Weight | 65 Pounds | | Harness Type | 5 Point Harness | | Installation Type | Latch | | Installation type | Latch | | Item Dimensions D x W x H | 68.6D x 61W x 50.8H centimeters | | Manufacturer | Dorel Juvenile Group | | Material | Wool | | Material Type | Wool | | Maximum Height Recommended | 52 Inches | | Maximum Weight Recommendation | 45.36 kg | | Minimum Weight Recommendation | 4 Pounds | | Model Number | CC208FNA | | Number of Height Positions | 10 | | Orientation | Forward Facing | | Product dimensions | 68.6D x 61W x 50.8H centimeters | | Rear Facing Maximum Weight | 40 Pounds | | Rear Facing Minimum Weight | 4 Pounds | | UPC | 884392949457 | | Unit Count | 1 Count | ## Product Details - **Brand:** Maxi-Cosi - **Colour:** Essential Black - **Installation type:** Latch - **Material:** Wool - **Orientation:** Forward Facing ## Images ![Maxi-Cosi Pria Max All-in-One Convertible Car Seat, Rear Facing Car Seat (4-40 lbs), Forward Facing Car Seat (22-65 lbs), High Back Booster Seat (40-100 lbs), Pure COSI, Essential Black - Image 1](https://m.media-amazon.com/images/I/81wc3FEGPaL.jpg) ![Maxi-Cosi Pria Max All-in-One Convertible Car Seat, Rear Facing Car Seat (4-40 lbs), Forward Facing Car Seat (22-65 lbs), High Back Booster Seat (40-100 lbs), Pure COSI, Essential Black - Image 2](https://m.media-amazon.com/images/I/810rr7R-rKL.jpg) ![Maxi-Cosi Pria Max All-in-One Convertible Car Seat, Rear Facing Car Seat (4-40 lbs), Forward Facing Car Seat (22-65 lbs), High Back Booster Seat (40-100 lbs), Pure COSI, Essential Black - Image 3](https://m.media-amazon.com/images/I/71LkdxT+88L.jpg) ![Maxi-Cosi Pria Max All-in-One Convertible Car Seat, Rear Facing Car Seat (4-40 lbs), Forward Facing Car Seat (22-65 lbs), High Back Booster Seat (40-100 lbs), Pure COSI, Essential Black - Image 4](https://m.media-amazon.com/images/I/81D9TelfmhL.jpg) ![Maxi-Cosi Pria Max All-in-One Convertible Car Seat, Rear Facing Car Seat (4-40 lbs), Forward Facing Car Seat (22-65 lbs), High Back Booster Seat (40-100 lbs), Pure COSI, Essential Black - Image 5](https://m.media-amazon.com/images/I/81I+uPn84YL.jpg) ## Questions & Answers **Q: What is the difference between the Pria 85 3-in-1 and Pria 85 Max 3-in-1?** A: Hi!

Volvería a comprar otra sin pensarlo ### ⭐ Save yourself from this disappointment. *by S***A on 6 July 2021* This car seat is only usable from 6 months. This is appraiser an estimate as of now. It could be 9 months too. Too big for rare facing position. The bottom of the car seat seems to damage the seat leather. ## Frequently Bought Together - Maxi-Cosi Pria Max All-in-One Convertible Car Seat, Rear Facing Car Seat (4-40 lbs), Forward Facing Car Seat (22-65 lbs), High Back Booster Seat (40-100 lbs), Pure COSI, Essential Black - Maxi-Cosi Pria All-in-One Convertible Car Seat, Rear Facing Car Seat for Infants from 4-40 lbs, Forward Facing Car Seat up to 100 lbs in Booster Seat Mode, After Dark - Maxi-Cosi Emme 360 Car Seat: Rotating Car Seat 360, All-in-One Convertible, Car Seat 360 Rotation, Swivel Car Seat in Midnight Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/443669160-maxi-cosi-pria-max-all-in-one-convertible-car-seat](https://www.desertcart.jp/products/443669160-maxi-cosi-pria-max-all-in-one-convertible-car-seat) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-06*
