Major Similarities Between Maxi Cosi Pria 85 vs Maxi-Cosi Pria 3-in-1

While the Pria 85 and the Pria 3-in-1 are both high-quality car seats, they only share a few small similarities. The biggest similarity between these two models is that they both utilize the One-Click LATCH Connectors to make installation faster, easier, and safer. These connectors also ensure that you install the car seat securely and correctly.

Smaller similarities between the Pria 85 and Pria 3-in-1 include the machine-washable seat pad and covers, the infant positioning wedge, and the 3 position recline base. Both car seats are equipped with a removable seat pad that can be removed without rethreading the harness. The infant positioning wedge provides comfort and support and ensures that your little one is seated properly and comfortably. Also, the 3-position recline base offers more room to position your child at an angle that’s comfortable and safe.

Additionally, while both of these car seats come with different harness systems, you don’t have to rethread them to adjust the harness. Both models use special harness adjustments that make it easier and quicker to adjust the harness with little effort.

Major Differences Between Maxi Cosi Pria 85 vs Maxi-Cosi Pria 3-in-1

The biggest difference between the Pria 85 and the Pria 3-in-1 is that that the Pria 85 is a 2-in-1 car seat that only offers the rear-facing and forward-facing positions with a minimum weight limit of 14 pounds, so it can’t be used from birth. The Pria 3-in-1, on the other hand, is a convertible car seat that offers the rear-facing, forward-facing, and booster positions with a minimum weight limit of 4 pounds, so you can use it from birth.

That being said, the Pria 85 will eventually need to be replaced when it’s time for your child to transition to a booster because it has a maximum weight limit of 85 pounds. Conversely, the Pria 3-in-1 has a maximum weight limit of 100 pounds, so it can be used until the time your child outgrows the need for a car seat.

Another difference between these models lies in the side impact protection. The Pria 85 is equipped with an Air Protect air cushion system that surrounds your child’s neck and head to provide superior protection against the impact force of a collision, and it’s been tested safe in both the rear-facing and forward-facing positions. The Pria 3-in-1 comes with built-in patented GCell foam that’s designed to absorb crash energy and provide the ultimate protection for your child’s neck and head.

Finally, the Pria 85 is equipped with a One-Hand Harness Adjustment that makes it easy to adjust the harness quickly and without too much effort. It can also be easily adjusted without rethreading the harness. The Pria 3-in-1 utilizes the Quick-Fit Shoulder Harness that automatically adjusts to comfortably fit your child’s growing height. Similar to the Pria 85, the Shoulder Harness can also be adjusted without rethreading the harness.

The Pria 85

Maxi Cosi Pria all-in-one vs 3-in-1

The Pria 85 is a 2-in-1 car seat that’s outfitted with CosiCushion fabrics and ample padding to provide a luxurious and first-class car riding experience for your little one. For an added measure of safety, the Pria 85 utilizes Air Protect side impact technology to provide superior head and neck protection in both the rear-facing and forward-facing positions.

 In addition to that, the Pria 85 comes with a One-Hand Harness Height Adjustment that makes it easier and quicker to adjust the harness, so much so that you can do with one hand. Along with the harness are convenient harness holders that secure the straps and buckle out of the way to make it easier and hassle-free to get your child in and out of their car seat. The Pria 85 also comes with a removable seat pad that’s machine-washable, and you don’t have to uninstall the car seat to remove it or put it back on. 

For added comfort, the Pria 85 features an infant wedge pillow that also offers support and promotes proper alignment while your child is their seat.

  • The Pria 85 is ues Air Protect side impact technology to provide superior protection for your child’s neck and head.
  • It comes with three recline for safer and comfortable installation.
  • The seat pad can be removed without installing the car seat, and it’s machine-washable.
  • For a 2-in-1 car seat, the Pria 85 has a high weight limit of 85 pounds.
  • The harness can be easily adjusted with one hand and without rethreading it.

  • For a 2-in-1 car seat, it’s a bit pricey.
  • The Pria 85 won’t be the first or last investment you make in a car seat. It can’t be used from birth, and it’ll have to be replaced when it’s time for your child to transition to a booster seat.

The Bottom Line

The Pria 85 is a high-quality car seat with premium features that work to drastically enhance safety and comfort. It comes with superior side impact protection and utilizes an easy-to-adjust harness system that can be adjusted without rethreading the harness. It also comes with One-Click LATCH connectors that make installation safer and easier. However, I will say that while the Pria 85 is equipped with such enhanced features, it may not be worth it to spend that much money on this car seat when it won’t be the first or last one you buy.

The Pria 3-in-1

Maxi Cosi Pria all-in-one vs 3-in-1

The Pria 3-in-1 is a convertible car seat that can last from birth until your child outgrows the need for a car seat. It has a very low weight limit of 4 pounds with a high maximum weight limit of 100 pounds. The Pria 3-in-1 comes with three recline angles to ensure that your child is seated at the safest and most comfortable angle.

It’s the only car seat you’ll ever need, and it has an exceedingly low weight limit of 4 pounds, unlike other name brand car seats. The Pria 3-in-1 is heavy-duty and comes with standard features that make it a worthy first and last car seat.

Maxi-Cosi Pria 85 and Pria 3-in-1 Video Overview

Conclusion

The Pria 85 and Pria 3-in-1 are both highly exceptional car seats that offer that ultimate safety and protection for your little one. Furthermore, they both have things, like any other car seat, that makes and breaks them from being the perfect car seat.

Out of the two, I recommend the Pria 3-in-1 because while it's pricey, it's the only car seat investment you'll have to make. It can be used from birth until your child outgrows the need for a car seat.

The Pria 85 is pricey, but you can't use it from birth and it can't be used as a booster, so somewhere down the line, you'll have to invest in another car seat. I don't think it's worth the money to do that when instead, you can buy the Pria 3-in-1 that'll last.
