Review: 10/10 Car Seat - This car seat is so nice! The install is very easy, how to adjust height is easy! I got it cause my little man hated the infant bucket seat and he loved this car seat as it seems to be more solid, more comfortable (padding is nice), and allows him to sit up straight better. 10/10! Also, I was worried it wouldn't fit well into a 2014 Toyota Corolla and it fits perfectly! 😁
Review: 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.)

### ⭐⭐⭐⭐⭐ Highly Recommend! We love this car seat!
*by E***S on January 12, 2026*

Bought this car seat for my 15 month old. I did so much research on car seats and their safety features/comfortability and this one was highly rated so I purchased it. She has been using it for a month now and I literally have no complaints! Easy to install the seat, as well as buckle and unbuckle her. She seems to be comfortable buckled in this seat.
