Updated as of February 2020: The Tiny Fit System of the Maxi Cosi Pria 70 is already hard to find nowadays, at least in online stores. And even if they are still widely available, I’d stick with my conclusion of choosing the Maxi Cosi Pria 85 Max* in the end.

The Maxi Cosi Pria 70 Vs 85 Max – two of the better choices when choosing which Maxi Cosi convertible car seat to get.

The Pria 70 is equipped with the Tiny Fit system and the Pria 85 Max has an infant wedge so they both can accommodate infants as young as 4 and 5 pounds. But which of the two is a better choice to get until your child is ready for the booster seat?

Read on.

Ideal Use


Pria 70 Pria 85 Max
Rear-Facing Weight: 9-40 pounds 14-40 pounds
Rear-Facing Weight with Tiny Fit Insert/Infant Wedge 4-22 pounds 5-15 pounds
Forward-Facing Weight: 22-70 pounds 22-85 pounds
Height Limit: Up to 52 inches

Using the Tiny Fit insert of the Maxi Cosi Pria 70 and using the Infant Wedge of the Maxi Cosi Pria 85 Max will allow you to use the seat for your newborn and for younger babies.

However, the Maxi Pria 85 Max has a higher weight limit.

They both have the same height limit though. But how are you able to know how heavy your child will end up to be in the future? I say it’s safer to choose a higher weight limit to maximize the seat.

For the longevity of usage, I’d go with the Maxi Cosi Pria Max 85.


Good All In One Car Seats


Will It Fit In My Car?


Pria 70 Pria 85 Max
Width 19.5 inches 20 inches
Height 25.5 inches 26  inches
Depth/Length 22.8 inches 21 inches

The size difference of the two seats is not much. They would both need as much space as they can take inside a vehicle.

If you are contemplating to get any of the two, make sure your vehicle is large enough to accommodate them.

Good 2-Way Car Seats

Do I need to use a pool noodle/rolled towel? No
Easy To Install Rear-Facing? No Yes
Easy To Install Forward-Facing? No Yes
Easy To Uninstall? Yes

Installing the Maxi Cosi Pria 85 Max seems to be way easier than dealing with the Maxi Cosi 70 Tiny Fit version.

Easy installation is one of the major factors that one must take into consideration when choosing a car seat.

Both seats are equipped with the “Air Protect” technology. This is a special kind of side impact protection that Maxi Cosi claims to be the “safest side impact protection” you can get in a car seat.

The buckle design, however, for the Max 85, is way easier to use and more secure.

The Seat


Pria 70 Pria 85 Max
Is The Material Breathable? Yes
Seat Weight: 24 pounds 17.5 pounds
Easy To Remove Cover? Yes
Machine Washable Cover? Yes
Roomy? Yes
No-Rethread Harness? Yes
Comes With An Infant Body Support? Optional Tiny Fit System/Comes With A Body Pillow Yes
Expiration 6 years 10 years
Comes With A Cup Holder? Yes
Shoulder Harness Has Pads? Yes

Both seats are as padded and comfy and have a premium, soft, plush fabrics.

The Maxi Cosi 85 Max is way lighter than the Pria 70 Tiny Fit, despite the higher weight limits.

Their seat covers are easily removable as the internal pieces are just connected with snaps and the overall seat can be easily loosened up to be removed for washing.

Although they are both machine-washable and dryer-safe, make sure that you use the gentle cycle to maintain the plushness of the fabric.

They are both roomy to accommodate a growing child and adjusting the seat-harness of both seats will not need manual rethreading. You can just slide the headrest up and down, and the harness height will go with it.

The Maxi Cosi Max 85 has a more generous expiration date so you can reuse it for younger siblings.

There’s at least a USD 60 price difference between the two seats – the Maxi Cosi 85 Max is more expensive. Now let’s see what the added USD 60 is for.

  1. It has a higher forward-facing weight limit.
  2. It is a little shorter, therefore, it would give “a little more” leg room for the seat directly where it’s installed.
  3. It’s easier to install in both the rear and forward-facing mode.
  4. It has an improved buckle design which makes it very easy for parents to secure their child in the seat, but difficult for the little hands to unbuckle.
  5. The Maxi Cosi Pria 85 Max is way lighter.
  6. It comes with an infant wedge (infant support.)
  7. The Pria 85 Max has a longer expiration date.

The only advantage of the Maxi Cosi Pria 70 with Tiny Fit insert against the Pria 85 Max is the price. You’ll save more but you’ll get fewer features and functions.

Between the two, I’d get the Maxi Cosi Pria 85 Max*.

  1. I definitely prefer the 85 Max for sure. You have done a lot of the leg work in comparing them to make this an easy choice. I just think with the 85 max, that I will be able to utilize it longer as it goes up to 85 pounds. Do you know what the car seat requirements are? I mean, how long do we need to keep them in a car seat before they can graduate to the seat belt. Is it different in each state?

    1. Hi there,

      Here is a helpful guide on child car seat laws for every state in the US as well as in Canada.

      There’s quite a difference in laws between states.

      I hope this helps.



  2. As you mentioned in your conclusion, $60 might be a lot of money for some. However, if you think of that cost being spread out over the months of usage for this product, it’s a small monthly cost.

    1. Yes Neil,

      And it’s not as if you’re only spending more for nothing. You have the six advantages over the Maxi Cosi Pria 70 to justify the additional money.
