  • QuikFit Headrest and Harness System: One-hand height adjustment raises the harness and head support together, so a growth spurt never means rethreading straps or reinstalling the seat
  • ReclineFit Comfort: Three reclining positions suit a relaxed ride, and plush infant pillows in ultra-soft padding keep smaller riders snug, then lift out once outgrown

Description

The Maxi-Cosi Pria All-in-One Convertible Car Seat is a 3-in-1 car seat for every stage: rear-facing car seat (5–40 lb, 19–40 in), forward-facing seat (30–65 lb, 34.4–49 in), and belt-positioning seat (40–100 lb, 43.4–52 in). One-hand height adjustment raises the QuikFit headrest and harness together, and the ReclineFit system adds three positions. Plush infant pillows in ultra- soft padding lift out easily. Fabrics pair PureCosi, made without added fire retardant treatment, with EcoCare recycled fabric, and the machine-washable cover is dryer-safe. A 5-point harness and two removable, dishwasher-safe cup holders finish this infant toddler car seat. Engineered and tested to meet or exceed federal safety standards. Meets federal Side Impact standard. Actual fit may vary; not all children will comfortably fit the full weight and height ranges listed. Designed by Parents, for Parents.

Comfortable, Easy to Clean, and Built to Last
We've absolutely loved this car seat and have been using it for quite some time. One of the biggest selling points for me is how easy it is to clean. As any parent knows, spills, snacks, and messes are inevitable, and the removable fabrics make cleanup much less stressful. My daughter has always seemed very comfortable in it, even on longer car rides. The padding is supportive, the harness adjusts easily, and I appreciate that it grows with your child through multiple stages, making it a great long-term investment. The seat feels sturdy, secure, and well-made, which gives me peace of mind every time we're on the road. Installation was straightforward, and it's held up beautifully through daily use. Overall, this has been one of our favorite baby purchases, and I would absolutely recommend it to other parents looking for a comfortable, durable, and easy-to-maintain car seat. ... show more

MAXI COSI PRIA CARSEAT (HIGHLY RECOMMEND) ⭐️⭐️⭐️⭐️⭐️
MAXI COSI PRIA CAR SEAT (INFANT & TODDLER) ⭐️⭐️⭐️⭐️⭐️ 5 STARS OUT OF 5 STARS MY FAMILY LOVES THIS CAR SEAT & CAN’T RECOMMEND IT ENOUGH. WE’VE ORDERED THREE OF THEM NOW FOR ALL OF OUR CHILDREN AND ARE EXTREMELY PLEASED! THE DESIGN IS MORE BULKY THAN MANY OTHER CAR SEATS BUT IT FEELS MORE SECURE AND COMFORTABLE AND PADDED FOR THE SEATED CHILD. INITIAL INSTALLATION IS A BIT TOUGH AND CONFUSING. THE CAR SEAT LATCHES THOUGH THE SEAT BELT SYSTEM IN THE CAR ITSELF, SO MANEUVERING THE CARS EXISTING SEATBELT THROUGH THE NECESSARY LATCHES IN THE CARSEAT CAN GET TRICKY, AT FIRST, KNOWING WHERE EACH STRAP SHOULD GO. ALSO, IF YOU DON’T HAVE SMALL HANDS THREADING THE SEATBELT STRAP PROPERLY IS DIFFICULT TO MANEUVER. THERE ARE TWO CUP HOLDERS INCLUDED WHICH SIMPLY TWIST IN TO CLASP. THE CUP HOLDER CUP ITSELF CAN BE REMOVED EASILY BY A CHILD BUT ARE QUICK AND EASY TO RESET. THIS CARSEAT COMES WITH PADDING AND INFANT INSERT PIECES TO ACCOMMODATE CHILDREN OF ALL AGES AND SIZES. EACH INSERT PIECE IS EASILY INSTALLED AND CAN BE SIMPLY REMOVED ONCE OUTGROWN. WE’VE USED THIS CARSEAT BOTH FORWARD FACING AND REAR-FACING AS ITS DESIGN IS MADE TO GROW WITH THE CHILD. ONE PROBLEM WE ENCOUNTERED WAS HAVING ENOUGH SPACE FOR THE DRIVER TO EXTEND THEIR SEAT BACK WITH THE CARSEAT PLACED DIRECTLY BEHIND THEM, WHEN REAR FACING. MEANING, AS A TALL PERSON, I WAS NOT ABLE TO HAVE MY DRIVERS SEAT AS FAR-BACK AS I NEEDED IT WHILE ALSO HAVING A REAR-FACING CARSEAT DIRECTLY BEHIND ME. WE HAD TO PREMATURELY FRONT FACE THE CARSEAT DIRECTLY BEHIND THE DRIVER TO HAVE ENOUGH SPACE TO COMFORTABLY DRIVE. (I AM 5’ 11” TALL AND THIS WAS IN A JEEP GRAND CHEROKEE— JUST FOR CAR AND DRIVER SIZE REFERENCE.) ... show more

Huge Upgrade from Safety 1st – Maxi-Cosi Pria is a Game Changer!
Review Image by Marie💕
After using the Safety 1st car seat for years, we finally switched to the Maxi-Cosi Pria for our 4-year-old—and I honestly wish we had done it sooner. The difference between the two is incredible. With the Safety 1st, my daughter constantly complained it was “not so comfy.” On longer drives, she would be fussy and miserable. The seat never felt stable, no matter how tightly we installed it—it wobbled every time we drove. The Velcro would peel off easily, the cup holders would either fall out or get unscrewed by my toddler, and there was no recline option, so she couldn’t rest or relax. Now with the Maxi-Cosi Pria, it’s a completely different experience: 1. My daughter tells me every day how comfy she is and so much more content on car rides. 2. The cup holders are built in and secure..they don’t come loose, twist, or fall off. 3. Installation was SO much easier. My husband said it snapped in effortlessly, and it feels solid in our back seat. 4. The seat reclines 3 ways and it has made naps+ long drives way more comfortable for her. The only minor downside is that the cup holders are a bit small, but so far all of her cups have fit. It’s also bulkier than our old seat, but that’s not an issue for us since we only have one child. Honestly, the added comfort and safety are worth every bit of extra space. If you’re going back and forth between Safety 1st and the Maxi-Cosi Pria, choose the Maxi-Cosi. It’s far more secure, better built, and clearly designed with both parent and child in mind. I’m so happy knowing we’ll be using this seat until she outgrows it around age 10. No regrets. This was one of the best upgrades we’ve made! ... show more

Very cushioned and sturdy

Review Image by Emily Christensen
We needed to switch my tall one-and-a-half-year-old to a front facing car seat. I read reviews about several different brands and price ranges for car seats. Many people mentioned that comfort and ease of installation were some of the reasons why certain car seats were more expensive. I decided to go with this one (after reading some good reviews), so my child could be more comfortable on long drives— which we do frequently. So far I am very happy! This seat is very cushioned and sturdy. My daughter seems very at ease now when we drive around! And installation wasn’t too bad. ... show more

Not the best for newborns
Color: SeaDrift Style: Original
The chair is nice! But it sits a too high of an angle for your newborn and doesn't offer the correct head support as his head slumps forward. We installed it correctly and triple checked, read the manual and even had my mum triple check. Thankfully we have an older Graco seat that sits lower so he'll sit in that and I'll have my 2 yr old move to the Maxi. It's a shame because I really wanted him to have a nice new car seat but it's really not suitable for when they're small ... show more

The best car seat! It is so secure and safe. The cleaning process is so simple and it has washed well for us several times. I love the safety latch system. It is so easy to get in and out of cars. Looking forward to continuing to use it as my little one grows
