Maxi Cosi Prima 85 vs Prima 70 | Which One is Better?

Car seats are an important part of parenthood. No matter what, you’re going to need one. They come in different sizes, colors, and have a ton of features to choose from. You may think that buying a car seat is simple, but since there are so many features to choose from, it makes the decision a lot harder than it has to be. 

Two car seats that have great reviews and are very popular are the Maxi-Cosi Pria 70 and the Maxi-Cosi Pria 85. Both of the car seats are from the same manufacturer and have many similar features and benefits.

For example, Pria 70 is slimmer, making it easier to fit into smaller vehicles. However, the Pria 85 can hold more weight longer. These are just two differences that set these two car seats apart. Let’s check out some other features. 

The Maxi-Cosi Pria 85 offers more comfort and longevity than the Pria 70, making it the better choice. However, both car seats have their strong suits. The Pria 70 is slimmer and can fit better in all vehicles whereas the Priam 85 is larger and is better suited for larger vehicles. Additionally, the Pria 85 has a higher weight limit than that of the 70. 

Let’s take a detailed look at everything both car seats have to offer including comfort, safety, portability, ease of use, and more. 


Safety is one of the most important features of a car seat. Both the Pria 70 and Pria 85 have an Air Protect Superior Side Impact Protection System. This is a system that surrounds the head to keep it in place during jarring movements.


The FlexTeach system is only in the Pria 70. It’s an advanced safety system that has multi-directional crash energy management and Air Protect for the best side impact protection possible. It keeps the seat stable at all times, no matter how hard or how much your child moves. 

Air Protect Side Impact Protection

Both the Pria 70 and Pria 85 have the Air Protect Side Impact Protection. This is a system that provides added safety for your child where it’s most needed-around their head.

No matter how hard you move or stop, your baby will be as safe as possible. 

Headrest Adjustment

Headrest adjustment is a feature that every car seat should have. As your child grows, the headrest will grow with them, providing optimal safety and comfort. These car seats are equipped with PerfectFit one-hand headrest adjustment. You can adjust the headrest into different positions that allow your child to feel as comfortable as possible. 


The ClipQuik system is an auto-magnetic clip in the chest that helps keep your child tight to the seat. Additionally, it’s a safety mechanism that keeps your child from opening the restraint while on the road, something that they can do with traditional car seats.

The only car seat that features this is the Pria 85. The Pria 70 allows you to easily tighten the harness, but it doesn’t have the added safety feature of the ClipQuik. 

Harness System

Both the Pria 85 and Pria 70 have 5-point harness systems. The Pria 70 has an upfront harness that has a 5-point security design that adjusts depending on how big or small your child is. The Pria 85 takes it just a step further.

Their 5-point harness system has a handy harness holder and flip-away buckle that keeps the straps out of the way so your child doesn’t sit on them while getting into their seat. It’s a great system for parents who are putting their children in the seat while they’re sleeping. 


Comfort is another important feature of any car seat. If your child isn’t comfortable, it’s going to be a long car or plane ride. Let’s check out the comfort features of the Pria 70 and Pria 85. 

Recline System

Both the Pria 70 and Pria 85 have recline systems. Both of them recline in three positions so you can make the car seat work for your toddler or newborn baby. The recline system is ideal for children who prefer to lay back or for those who may suffer from acid reflux and need to sit straight up. 

Size Limits

Both car seats can be used in two different ways. You can put them in rear or front-facing positions. The Maxi Cosi Pria 70 can accommodate babies as low as 9-pounds and as much as 70-pounds.

The Pria 85 begins at 5-pounds for front-facing (with the removable insert for smaller babies) and ends at 85-pounds for forward-facing. Both car seats have extended rear-facing mode to accommodate children up to 40-pounds since it has been advised to keep a child rear-facing until they are two years old. 

As you can see with the size limits, the Maxi Cosi Pria 85 can withstand more weight and you have 8” more room than the Pria 70. This means that you would get more usage out of the Pria 85 as opposed to the Pria 70.


The installation for both the Maxi Cosi 85 ad Maxi Cosi 70 is the same. While installing for rear-facing mode, the back padding of the car seat needs to be removed to adjust the latch or seat belt to the proper guide. 

The forward-facing mode is easier to install. In order to ensure it’s as tight and snug as it can get, you have to put all of your weight into it to remove the added slack. It’s easier to put your knee into the seat and press down while adjusting the belts. 

When the Maxi Cosi Pria 85 is installed in your car, it will take up more room than the Maxi Cosi Pria 70. This car seat is ideal for larger vehicles if you have multiple passengers. There’s just enough space for the passengers in both the front and back of the vehicle. The Pria 70 is a great fit for all vehicles with its more narrow base. 

Material & Construction

We all know that infants and toddlers are prone to blowouts and other accidents. These car seats have covers that can be removed easily for machine washing and drying. It’s best that they are washed in cold water and on a gentle cycle.

You can then throw the dryer for a fresh car seat cover that can be put right back in the car seat.  The best part is that you don’t have to remove the car seat to remove the cover. 

The overall construction of both car seats is pretty solid. It ensures your child is unmovable but still comfortable. Additionally, the fabric is self-wicking. This ensures that the seat stays dry when your baby isn’t using it. 

Additional Features

Both the Maxi Cosi Pria 70 and Maxi Cosi Pria 85 have integrated cup holders for your child’s sippy cup or light snacks. Additionally, both car seats come with a removable insert to accommodate smaller babies. The TinyFit insert on the Maxi Cosi Pria 70 is about 16-inches from the sear bottom to the top of the head area. This insert also lowers the weight limit for the Maxi Pria 85 to 5-pounds as opposed to 14-pounds.

Both car seats have a variety of colors to choose from. The Maxi Cosi Pria 85 only has 6 colors whereas the Maxi Cosi Pria 70 has 8 colors to choose from. Some are simple colors and others are multi-colored that will keep babies captivated during their ride.
