It has a layer of side impact protection, making it 2X safer in side impact crashes and received a 5-star rating in all categories in tests conducted by the National Highway Traffic Safety Administration (NHTSA).

It also offers more cushion and plush foam padding, a 15-position headrest for better support, and more recline options and headrest adjustability for a more customized fit.

Safety

According to expert reviews, both the Graco 4Ever DLX and Britax One4Life car seats are designed with advanced safety features to protect children in case of accidents. However, the Britax One4Life has a layer of side impact protection, making it 2X safer in side impact crashes and received a 5-star rating in all categories, including frontal crash, side crash, and rollover in tests conducted by the National Highway Traffic Safety Administration (NHTSA).

Additionally, it has a solid steel frame, SafeCell impact absorbing technology, an anti-rebound bar, and two layers of side-impact protection in infant mode. On the other hand, the Graco 4Ever DLX has the ProtectPlus Engineered safety technology, which is tested to protect children in every possible direction in case of frontal, side, rear, and rollover crashes.

It also exceeds the minimum requirements set by Federal Motor Vehicle Safety Standard 213 for crashworthiness, flammability, and other important safety features.

If side-impact protection is a top priority, the Britax One4Life may be the better choice as it has specific safety ratings for side-impact protection and additional safety features such as SafeCell technology and EPS foam. However, if ease of use and frequent adjustments are important, the Graco 4Ever DLX may be a better option as it has a no-rethread harness.

Ultimately, it's important to consider the specific needs of your child and prioritize safety when choosing a car seat.

The 2021 Britax One4Life is a convertible car seat that can be used from birth until 120lbs, making it the only car seat parents will need for their child's life. It is easy to install, has excellent safety features, and offers convenience and comfort for both parents and children.
+ pros
  • Easy installation for all parents, with a belt tensioning plate and steel rod to lock in pressure.
  • Sturdy construction with a hard steel frame and two layers of EPS foam for side impact protection, as well as safecell technology to spread force away from the child.
  • Comfort features such as dual cup holders, non-rethread harness, 9-position recline, and built-in cooling channels and ventilated mesh.
  • Longevity, with the potential to last from age 1 to when the child no longer needs a car seat.
- cons
  • The author suggests using an infant car seat for the first year for comfort and ease.
  • The height limit on the seat may be reached before the child is done with car seats altogether, so parents should consider their child's age and size before transitioning to a booster seat.

The Graco 4Ever DLX has good crash test results and easy-to-use shoulder height adjustment, but falls short in quality and comfort compared to similarly priced competitors. The author does not recommend this seat and suggests purchasing specific seats for each stage of life, with the Graco Extend2Fit being a better option.
+ pros
  • Better-than-average crash test results with sensor data significantly better than federal guidelines.
  • Bubble level indicator and adjustable angle for comfort.
  • Easy-to-use shoulder height adjustment and onboard manual storage.
- cons
  • Challenging installation using LATCH and vehicle belt with threading the straps being a pain.
  • Stiff and less intuitive harness buckle and chest clip.
  • Falls short in terms of quality and comfort compared to similarly priced competitors, with a wider seat that makes it difficult to use with multiple safety seats or for an adult to sit between two seats.
The Graco 4Ever DLX is a versatile car seat that can be used from infancy to booster age, with a weight range of 4-120 pounds and a height range of 43-57 inches tall. It has a RapidRemove cover and forward facing lockoffs, making it easy to use and install, and is a solid choice for caregivers looking for a reliable car seat that can be used for many years.
+ pros
  • Versatile and can be used in multiple modes from infancy to booster age.
  • RapidRemove cover system allows for easy cleaning.
  • Can be installed with lower anchors or vehicle seat belt.
  • Has forward facing lockoffs for easy installation.
  • Optional shoulder belt guide adjuster for backless booster mode.
  • FAA approved for use on board aircraft when the harness is in use.
- cons
  • Cupholders are not removable and must be installed before the car seat is installed in the vehicle.
  • Lower anchor storage locations are not clearly explained in the manual.
  • More pieces to put back together if fully disassembled for cleaning.
