This review used to be for the Maxi Cosi Pria 70 Tiny Fit version of the Maxi Cosi Pria 70 Convertible Car Seat. It seems that the Tiny Fit version has already been discontinued, so I have updated this review to reflect the version without the Tiny Fit. Learn more.

The Maxi Cosi Pria 70


Ideal Use


Rear-Facing Weight: 9-40 pounds
Forward-Facing Weight: 22-70 pounds
Height Limit: Up to 52 inches

The Maxi Cosi Pria 70 Convertible car seat is one of the few convertible car seats that have a high minimum requirement for placing a child in the seat for the first time.

Its rear-facing weight limit starts at 9 pounds. Parents who would like to use it for their child from birth should get the Tiny Fit version, which has a “seat” within the seat.

The tiny fit insert will allow you to have your child seated for as early as 4 pounds.

See the video on how to do it.

Will It Fit In My Car?


Width 19.5 inches
Height 25.5 inches
Depth/Length 22.8 inches

The Maxi Cosi Pria 70 comes with three recline positions. When you fully recline it in the rear-facing mode, expect to occupy a lot of space in your vehicle.

Also, it is not narrow compared to some seats that can fit three in a row. You won’t be able to do that with the Pria 70.


Good Two-Way Car Seats




Do I need to use a pool noodle/rolled towel? No, but allowed as per manual
Easy To Install Rear-Facing? Yes by LATCH

Relatively by seatbelt

Easy To Install Forward-Facing? Relatively
Easy To Uninstall? Yes

There are only a few parents who got lucky with easily installing the Maxi Cosi 70 seat. Rear-facing, it’s apparently easier to tighten the straps if you first pull the seat cover aside and pull it from the inside under the seat cover. See how the car seat lady does it.

However, there are also some people who can tighten it without having to remove the car seat cover aside. See this video.




Country Of Origin: USA
Steel Frame: No
Five-Point Harness? Yes
Side Impact Tested: Yes
Approved For Airplane Use: Yes
Easy To Buckle And Unbuckle? No

There’s a major safety concern that the Pria 70 has. It’s difficult to tighten the harness once your child is in the seat.

I don’t know if you notice, but from the first video on top where it shows how to attach the tiny fit insert, they pulled the seat harness from behind the seat “to make it easier” to tighten it.

That is not ideal especially when your seat is installed in the forward-facing mode where you have to get hold of the straps from behind the car seat, which is pressed firmly against your vehicle seat.

You need to “help” move the strap from behind the car seat since it can get caught in the “ridges” behind.

See this video.


Why Is It Hard To Tighten The Seat Harness Of The Maxi Cosi Pria 70?

The Seat


Is The Material Breathable? Yes
Seat Weight: 23 pounds
Machine Washable Cover? Yes
Roomy? Yes
No-Rethread Harness? Yes
Comes With An Infant Body Support? Yes, body pads
Easy To Remove Cover? Yes
Expiration 6 to 8 years
Comes With A Cup Holder? Yes, 1 
Shoulder Harness Has Pads? Yes
Crotch Pads? No

It has a machine-washable cover that’s easy to remove.  It is good that the fabric is breathable and “draws liquid away from the skin,” which is useful especially during hot weathers.

The Maxi Cosi 70 is not the lightest convertible car seat there is, but it is also not the heaviest.

It is roomy and wide, no problems with trying to fit even older chubby kids.

You wouldn’t have to manually rethread the seat harness as it is connected to the headrest which you can just move up and down should you need to adjust the harness height.

The seat expires six to 8 years from the date of manufacturing.

It’s good it already comes with a cup holder and shoulder harness pads.

And lastly, it comes in pretty colors and designs.

The first thing I am worried about this seat is how difficult it can be to adjust the seat harness. If this will be used on a daily basis, then you will have a problem.

It is doable to access the straps from behind the seat when in a rear-facing mode so you can adjust the straps easily. But I doubt if you can comfortably adjust it in the forward-facing mode, especially that the back of this car seat will be firmly pressed against your vehicle’s seat.

The installation issues, I can probably handle. 

I like how padded and comfy it looks, just like how most parents would say that it is.

I also like how beautiful the seat colors and prints are. But that would not be enough to convince me to get it.

I highly suggest that you check out the feedbacks of the parents who got this seat to learn more about it.

  1. You point out that it’s very difficult to strap in, in particular for daily use. Let’s be honest you do need daily use if not multiple daily uses? Also, I am also not sure if it has a reclining function once it’s forward facing for those long trips?

    1. Hi Helen,

      I’m not sure how you intend to use a seat, but for parents driving their kids to somewhere every single day, the difficulty in strapping in their kids to the seat can possibly cause them to get late for school, or the parent for work. Unless you are going to use the Maxi Cosi Pria 70 only when you are not rushing to go somewhere.

      For the forward facing recline, children who are 22-40 pounds must use the angle 2, while children who are 40-70 lbs must use the angle 1.


  2. I like the look of the seat, but after reading your review on it, I don’t think I would purchase this until I do more searching of other car seats. This car seat is for babies starting at 9 pounds. All my babies were less than that, This information was very helpful.
