In this review, we will compare The Graco 4ever and the Britax Allegiance. The Britax Marathon G4.1 is the old name before they “upgraded” it to become the “Britax Allegiance.” In essence, they are the same seats.

While the Britax Allegiance can be tempting because of its good reputation, the Graco 4ever is a sure winner when compared side by side with it.

See why.

Comparing the two seats is like comparing apples and oranges. The Graco 4ever is an All-In-One car seat while the Britax Allegiance is only a two-way car seat.

Graco 4ever will definitely be more usable longer.

Be careful when choosing the color of the seat fabric of the Graco 4ever. Avoid the dark ones as they can be unbreathable.

The Allegiance is lighter than the Graco 4ever. If you need to keep on transferring it between vehicles, it’s good to know that it’s not that heavy.

You have to remember that the seat cover of the Allegiance is only good for hand-washing.

The Graco 4ever has three years more than the Allegiance before it expires.

And lastly, the Allegiance does not come with a cup holder as it is. However, some sellers*, as a promotional offer, include a cup holder for selected colors.

Conclusion


 

The Graco 4ever is approximately USD10 away from the Britax Allegiance and is more expensive. Let’s see what the added cost for Graco 4ever is.

  1. We can use it as a booster with a height limit of 57 inches and a weight limit of 120 pounds.
  2. It is easier to install both in the rear facing and forward facing mode.
  3. It has a machine washable cover.
  4. It has a more generous expiration date.
  5. Regardless of where you buy it from, it comes with a cup holder.

The above six points are more than enough to justify the added USD 10 cost.

As for the advantages of the Allegiance against the Graco 4ever, you have the following to take note of.

  1. It can be a space-saver in the forward-facing position.
  2. It is made in the USA.
  3. Regardless of the color that you choose, you’ll end up with a breathable seat.
  4. It is lighter, just in case you need to air travel with it.

If it’s on sale, the Allegiance doesn’t seem so bad. But its longevity is restricted.

Given the above points, I’ll choose the Graco 4ever.*

  1. Hi Pitin, I have a 9 months baby boy. 6 months ago I bought a Baby car seat brand name Aprica because my wife’s parent is living in Wakayama. We have to drive around 4-5 hours from Osaka to reach there. The baby car seat seems not so comfortable ’cause my baby keeps moving and yelling. I wonder which baby car seat is the most suitable for long journey. Your advice will be greatly appreciated. Thanks

    Regards, 
    Wilson

    1. Hi Wilson,

      Both seats are padded enough for comfort, but the Graco 4ever will surely give you back your money’s worth. As long as you stay away from the Matrix color (which is said to be unbreathable), I personally think that going the Graco 4ever way is a wiser choice.

      Regards,
      Pitin
