The Similarities

Installation latch

A similar feature in both One4Life and 4Ever DLX models is the installation latch. Graco calls it Push-button Inright LATCH while Britax just calls it LATCH. They both function the same way by latching to the main backseat of your vehicle in the rear-facing position to ensure maximum tightness and least movement or wobble.

Harness & Strap Storage

Having the harness straps and latches dangling around when carrying the car seat is a thing of the past. Most new model car seats are built with latch holders and harness storage compartments to make sure nothing comes in the way of the other during installation or when carrying the car seat in and out of the vehicle.

Level Indicators

One of the greatest advantages in the Britax One4Life and the Graco 4Ever DLX car seats is the built-in level indicator. This is an excellent guidance system to latch the car seat in the perfect angle and recline position for maximum safety. You do not have to release and adjust the seat multiple times until it stops wobbling – the level indicator does this job for you in the first go.

Rapid Removable Covers

A hard thing to find in most baby car seats is the ability to remove the cover as quickly as possible. Most car seats including the popular ones like Graco Extend2Fit do not come with quick-remove car seat covers. You have to remove the car seat from the vehicle and unhook many different points to release the cover before you can get it washed.

The Britax One4Life and Graco 4Ever DLX both come with quick-remove car seat covers. You can remove these covers within a minute or two and have them machine-washed without any headache or complications.

Cup Holders

Both car seats come with 2 cup holders – one on each side. The ability to clean them is very important for hygienic purposes. Both One4Life and 4Ever DLX cup holders are easily removable for cleaning purposes.

The Differences

Recline positions

Having multiple recline positions helps you set the best position for your baby’s comfort. The Graco 4Ever DLX comes with 6 recline positions which on its own is a pretty high number when compared to other baby car seats on the market.

The Britax One4Life on the other hand comes with 9 quick push recline positions. The simplicity of adjusting the recline position as the name suggests – Quick push.

  • Graco 4Ever DLX 4-in-1: 0

Backless Booster

The Graco4Ever DLX comes with 4 different car seat modes, rear-facing, front-facing, high-back booster seat, and backless booster. The backless booster comes with a weight limit of up to 120 lbs. while the high back booster stops at 100 lbs.

The Britax One4Life comes with 4 modes as well with a high back booster being the final stage. The high-back booster seat has a weight limit of 120 lbs. which is similar to the limit of the backless booster in Graco 4Ever DLX.

Both backless and high-back booster seats have their pros and cons. The main advantage of a high back booster is the added safety against whiplash and side impact during a crash but it is still bulky and looks childish for a grown child.

The backless booster is more lightweight, compact, and provides more space for the child but lacks the added safety provided by a high-back booster.

Since both One4Life and 4Ever DLX support children up to 120lbs, this point lands in a tie.

The tie breaks if you as a parent decide which would be more preferred, the backless booster seat or the high back booster for a grown child weighing more than 100 lbs.

Rear Facing Weight Limit

The Britax One4Life has a weight limit of up to 50lbs in the rear-facing mode whereas the Graco 4Ever DLX stops at 40lbs in the rear-facing mode.

Babies can be chubbier for their age – they would still require to be secured in rear-facing mode but the 4Ever DLX limits the baby weight to 40lbs.

The One4Life wins this round since babies can be chubbier for their age – requiring additional weight support in the rear-facing mode.

  • Graco 4Ever DLX 4-in-1: 0


Although nothing much is mentioned about fabric type or quality in the description for the Graco 4Ever DLX car seat, we were able to understand from customer opinions and feedback that the fabric is quite breathable and comfortable.

Comparatively, Britax One4Life actively promotes the level of breathability in its car seats with cooling channels and ventilated mesh. They have deliberately made sure that the car seat is highly coolant and breathable for the child.

This makes One4Life more recommended for continuous use and long-distance traveling.

  • Graco 4Ever DLX 4-in-1: 0.5

Adjustable Head Rest

Both One4Life and 4Ever DLX come with quick-adjust headrest systems. You can adjust the height of the headrest with the pull of a button. This is a feature that should be found in most baby car seats but unfortunately, it’s limited to the elite few.

The main difference here is the number of headrest positions each car seat brings to the table. The One4Life from Britax has 15 headrest adjustment positions while the 4Ever DLX from Graco comes with only 10.

If you think deeper, the difference wouldn’t matter much. The extra 5 height positions in Britax are to support the height of a grown child weighing between 100 to 120 lbs in the high back booster position.

The 4Ever DLX goes into backless booster mode at this point, meaning the headrest of the actual vehicle seat would now be used for the child passenger on the booster seat. In this case, the extra 5 height adjustment options wouldn’t be required.

Nevertheless, some children can be taller for their age requiring higher headrest support in comparison making Britax One4Life car seat the winner in this scenario.

Optional Rebound Bar

The rebound bar is an excellent safety feature that prevents the impact of recoil in the event of a crash. Although a crash should NEVER happen, having the anti-rebound bar gives you comfort that you have done your best in providing maximum safety for your baby.

Graco 4Ever and the 4Ever DLX do not come with an anti-rebound bar, and you do not have the option to add it separately either. Check out this report on Graco Extend2Fit if you want similar features with Anti Rebound Bar included.

The Britax One4Life surprisingly provides you the option to purchase the Anti-Rebound bar separately and install it on the seat when necessary or remove it when not needed. You can also choose to purchase the One4Life with Anti Rebound bar installed.

Belt Lock Off

When installing the car seat in the front-facing position, the Britax One4Life and Graco4Ever DLX come with their special titled installation systems.

The Britax One4Life calls it Clicktight, and the Graco 4Ever DLX calls it Belt Lock-Off. Both systems are quite similar although Britax Clicktight takes a little less effort to secure with the vehicle seat belt when compared to the Belt-lock-off from Graco.

The tether that locks to the back of your vehicle seat is where the difference kicks in.

The Britax One4Life comes with a special V-Shaped tether strap that reduces any kind of movement in the car seat once secured. The Graco 4Ever comes with a standard tether strap that also does an excellent job in its own right, but when compared against One4Life, 4Ever DLX loses the score.

  • Graco 4Ever DLX 4-in-1: 0.5

Check the video below to see the difference in the belt locking systems.




  • Britax One4Life Clicktight 4-in-1: 7
  • Graco 4Ever DLX 4-in-1: 2

According to the final count of score points, Britax One4Life Clicktight 4-in-1 car is the best of both when compared to Graco 4Ever DLX 4-in-1 car seat.

The 4Ever DLX is an excellent car seat with well-rounded features. It is still an exceptional baby car seat when compared with other models in its price range, but when compared to the Britax One4Life car seat, the latter offers newer and advanced features, comfort, and user-friendliness.
