Width

20.5 inches

21.5 inches

Height

Depth/Length

25 inches

27 inches


The Britax One4Life is 20.5 inches wide, while the Maxi Cosi Pria Max 3 in 1 is 21.5 inches wide. The One4Life's narrower width can be an advantage for families with multiple children or larger passengers, as it can help to have more than 1 car seat in the same vehicle or accommodate larger passengers in the backseat.

The One4Life is 19.5 inches high, while the Maxi Cosi is 24.75 inches high. The Maxi Cosi Pria's taller height may be a consideration for families with smaller vehicles or lower ceiling heights.

The Britax One4Life is 25 inches deep, while the Maxi Cosi Pria Max is 27 inches deep. The depth or length of the car seat can be a consideration for parents who need to fit the car seat in a tight space or want to ensure there is enough legroom for someone sitting behind or in front of the car seat.

Both the Britax One4Life and the Maxi Cosi Pria All-In-One car seats present challenges during installation. 

While the Britax One4Life can be challenging to tighten properly when using the LATCH system, seat belt installation is relatively straightforward. However, seat belt installation can be difficult for users with weaker hands or limited mobility. 

The Maxi Cosi Pria All-In-One car seat also poses challenges during installation, with some of the installation steps not being clearly explained. Additionally, ensuring that the car seat is level using the line indicator can be challenging, although using a rolled towel may make this step easier.

The Britax One4Life car seat is equipped with multiple advanced safety features that are designed to provide enhanced protection for children while travelling. 

Firstly, the seat incorporates a high-strength steel frame, which increases its durability and strength, and is intended to maintain its structure during a collision, thereby reducing the risk of injury to the child.

Secondly, the seat comprises two layers of side-impact protection, which act as additional cushioning in the event of a side collision. 

Finally, the One4Life incorporates the SafeCell Technology, an exclusive feature that serves as a crumple zone located in the base of the seat, absorbing crash energy and minimizing its effect on the child.

Although the One4Life's safety features are advanced, some parents have reported issues with buckling and unbuckling the child, inconsistent harness tightening, and the possibility of children escaping from the harness. On the other hand, no such concerns have been raised regarding the Maxi Cosi Pria Max 3 in 1, which lacks the advanced safety features of the One4Life.

Both car seats feature breathable materials, a machine-washable cover, a spacious interior, no-rethread harnesses, two cup holders, shoulder harness pads, and a 10-year expiration date.

While the Maxi Cosi Pria Max 3 in 1 weighs 22 pounds, the Britax One4Life is heavier at 30 pounds. Additionally, the One4Life offers more headrest positions (15) and recline positions (9) than the Pria Max 3 in 1, which only has 5 headrest positions and 3 recline positions.

However, the seat cover of the Maxi Cosi Pria Max is more convenient to remove for washing than the Britax One4Life.

My Final Verdict


There is an approximately USD 100 price difference between Britax One4Life and Maxi Cosi Pria Max 3 in 1. The One4Life is more expensive.

With the Britax One4Life, you get

  • Higher rear-facing weight and height limits
  • Higher booster mode weight and height limits
  • A more compact seat
  • A steel-reinforced frame
  • Added safety features
  • More headrest positions
  • More recline positions

With the Maxi Cosi Pria Max, you get

  • A 5-point harness that is easier to buckle and unbuckle
  • A lighter seat
  • An easier-to-remover cover
