In terms of rear-facing weight, the Graco Slimfit can accommodate infants from 5 to 40 pounds, while the Maxi Cosi Pria Max All In One can accommodate babies from 4 to 40 pounds. This means that the Maxi Cosi Pria Max All In One can be used for smaller infants.
When it comes to forward-facing height limits, the Graco Slimfit can accommodate children from 27 to 49 inches, while the Maxi Cosi Pria Max All In One can accommodate children from 29 to 49 inches.

Width | 19.88 inches | 21.5 inches |
Height | 25.5 inches | 24.75 inches |
Depth/Length | 21.5 inches | 27 inches |
The Graco Slimfit and the Maxi Cosi Pria Max All In One have some differences in size and dimensions.
The Graco Slimfit is narrower than the Maxi Cosi Pria Max All In One, with a width of 19.88 inches compared to the Pria Max's width of 21.5 inches. This could be an important consideration for families who need to fit multiple car seats across the back seat of their vehicle.
However, the Maxi Cosi Pria Max All In One is slightly shorter in height than the Graco Slimfit, with a height of 24.75 inches compared to the Slimfit's height of 25.5 inches. This could be an advantage for parents who have limited headroom in their vehicle.

The Graco Slimfit car seat features a collapsible cup holder that can be folded when not in use. By collapsing the cup holder, the car seat becomes narrower, making it easier to install in smaller vehicles or in situations where space is limited. This design feature allows the car seat to be more versatile and adaptable to different situations, while still providing a convenient cup holder for your child's drink or snack when needed.

Do I need to use a pool noodle/rolled towel? | No | Yes |
Easy To Install Rear-Facing | Yes | No |
Easy To Install Forward-Facing? | Yes | No |
Easy To Uninstall? | Yes |
In terms of ease of installation, the Graco Slimfit All In One appears to be easier to install than the Maxi Cosi Pria Max All In One.
The Graco Slimfit can be installed easily using both LATCH and car seat belt in all modes, and it has a clear and easy-to-read recline indicator. The Graco Slimfit's LATCH installation is particularly easy, with the recommendation of pressing the car seat towards the back and giving the LATCH strap a sudden hard pull. For forward-facing installation, you need to pull away the cushion on the front seat to access the seat belt path.
On the other hand, the Maxi Cosi Pria Max All In One installation can be tricky, especially with the LATCH installation. It requires a specific step to route the very end of the lower latch belt through the same path back from right to left, then pull it through the opening below the lower cushion, which is not always explained in detail in videos.
The “line” indicator for the Maxi Cosi Pria Max is also more difficult to read and leveling it can be challenging. The manual suggests placing a rolled towel under one end of the base to make installation easier.
In terms of the need for a pool noodle or rolled towel, the Graco Slimfit does not require one, while the Maxi Cosi Pria Max All In One manual suggests using one to make installation smoother.
Overall, the Graco Slimfit appears to be a more straightforward and easier-to-install car seat than the Maxi Cosi Pria Max All In One.
