Car Seat Purpose

Traveling is convenient with a private vehicle, but the road is not the safest place to be, especially for small children. Motor vehicle accidents are still one of the highest contributors to injury and death, but it is also preventable. We can’t see the future and what happens out there, but we can always prepare for them. When traveling, children need their car seats because the seatbelt cannot retain their small and fragile bodies. Parents can use the ideal safety seat according to the capacity.

The function of a car seat for children is to retain their body to the seat. The retaining purpose is what a seatbelt does for an adult, but a standard seatbelt is too large to fit the smaller users properly. The children’s car seat uses a harness instead of a seatbelt. The five-point harness lock on the crotch and chest to retain the passenger when there is an impact. The harness distributes impact and reduces concentrated effects that can be more dangerous for the passenger.

The other function is to reduce the overall impact transferred to the body. There will be an energy transfer from the collision to the passengers, and the car seat has a shell that bridges this process. Car seats also have standards, so every US unit must meet or surpass them. Parents can see the information on each product. But, some models have added features to reduce impact transfer further and are considered a better choice for increased protection.

About Britax Emblem and One4Life

Parents have to provide an ideal car seat for their children and follow the instructions, including the capacity for each growing stage. In general, parents can install a car seat facing the rear or the front of the vehicle. We also can’t use a rear-facing car seat on the front or passenger side because the airbag may injure or kill the younger children. The convertible car seat is the most convenient and long-lasting among the car seat types because it promotes two installation modes.

Models like Graco Grows4Me Vs Graco 4Ever DLX can fit babies from day one until they are in elementary school because the seats convert into a booster. For parents who plan on changing their seats later, Britax Emblem and One4Life are two exciting options from the company. They are quite different because one is a convertible model. The latter is a 3-in-1 variant meaning parents may be able to use the One4Life for longer than Emblem, especially if your little one is growing rapidly.

However, does it mean that One4Life is the better choice? Unfortunately, we don’t think so because the crash test for this seat produces more energy transfer than many similar seats in Britax’s collection, including the Emblem. The Emblem is Britax’s Essential line of the car seat, and it has a good amount of features but is also more basic. The crash test shows that Emblem can dampen the force more effectively than One4Life. But, we have to put more effort into installing Emblem than the other seat.

Overall we think the Britax Emblem and One4Life are good options for different parents. The two meet or surpass FMVSS 213, so they are safe, but Emblem has better impact absorption. If parents don’t mind spending on a booster seat later, we highly recommend the Emblem as it is more reassuring. While not the most convenient, the Emblem is still relatively easy to install.

Britax Emblem and One4Life Design

Like most car seats, the Britax Emblem and One4Life are very similar. There are no unique features upon looking at these seats, but they look pretty different. The One4Life is a bigger seat because it also converts into a booster, and it is heavy. The Emblem is approximately 18 pounds, and One4Life is 30 pounds. The aesthetic is also different, and One4Life has a wider seat pan to accommodate taller or older children. The fabric quality is the same, and they are soft to touch.

The padding or fabric is removable for cleaning and maintenance. Because the One4Life converts to a booster, the back or sides are not streamlined with its base. The One4Life also has two cup holders, which is missing from Emblem. The widest part of Emblem is approximately 18.5 inches, while the latter is slightly wider at 19 inches. Both seats will expire after 7 and 10 years from the manufacturing date.

Installing Britax Emblem and One4Life

Car seat installation is vital because the seat needs a proper installation to work and secure the passenger. Parents can install the Britax Emblem and One4Life using low anchors or seatbelts and add a tether when in forward-facing mode. The main difference in installation between Britax Emblem and One4Life is the ClickTight feature missing from Emblem. This feature is present in many other Britax seats and very useful to open the seat panel without manually removing the fabric.

ClickTight only requires a button press to expose the belt path, which is convenient and straightforward, especially for new users. The seats can use LATCH or lower anchor for rear and front-facing, but there is a weight limit; 35 pounds for One4Life and 50 pounds for Emblem. There are two versions of One4Life because some people get the seat with a traditional hook, and some have the more modern Safeguard connector. The low anchor weight limit is also due to One4Life heavier seat weight.

The forward-facing installation is just as easy with the ClickTight feature, as parents only need a button press to open the base and route the seatbelt or low anchor to the forward-facing mode. The installation is the same for Emblem, but it requires more effort since we have to open the seat manually; the actual routing and installation are the same. Make sure to attach the tether for forward-facing because it improves safety.

Britax Emblem and One4Life Fitting

Next is the fitting, which is similar to Britax Emblem and One4Life. They are suitable for day one, depending on the baby’s length. Preemies and smaller babies will need the insert to improve fitting, or if your baby is bigger, we can remove the insert so they can be more comfortable. The seat should fit a baby and toddler up to 40 pounds for Emblem and 50 pounds for One4Life, or the head is one inch lower than the top of the headrest.

We can move into the front-facing mode after the kid is tall enough or too heavy for rear-facing mode. The Emblem will be ideal for toddlers and children up to 65 pounds using front-facing mode and seatbelt installation with tether. The upper height limit is 49 inches, and the highest harness point is 16.75 inches. The One4Life also has a capacity of 65 pounds for front-facing mode with a harness and 49 inches height limit. But, it can convert into a booster with up to 120 pounds of weight capacity.

The harness is tucked away behind the seat in booster mode as parents secure the seat and children with the seatbelt. Children who are no longer comfortable or fit in the harness can use the seat in booster mode until they are 63 inches tall. Because One4Life doesn’t convert into a backless booster, some kids who grow faster or have the genetics to be tall may be able to use the seatbelt without a booster shortly.

Britax Emblem and One4Life Performance 

Lastly, let’s see the impact testing for Britax Emblem and One4Life. The testing essentially measures the vibration that happens to the body or, in this case, sensors placed on the dummy. The lower the vibration, the more effective the seat is at dampening the impact from accidents. The test shows that Emblem, along with the Allegiance from the same line, is more effective at reducing impact transferred to the dummy than One4Life, which, surprisingly among the lower of several Britax’s seats.

Britax Emblem Vs One4Life

Both Britax Emblem and One4Life are good car seats and are easy to install. But, these seats are also quite different because One4Life is a 3-in-1 seat that converts into a high back booster with a higher weight or height capacity. The seat has ClickTight, which improves the installation process and makes it even more convenient. But, the impact test shows that Emblem is more effective at reducing energy transfer. The Emblem also has a higher weight limit for front-facing mode using low anchors.

There is no wrong option because both seats meet and exceed the FMVSS 213 standard. But, we recommend the Emblem, especially if you have a greater concern about impact transfer. The One4Life is ideal for parents who want to use the seat for longer or have a baby who will grow rapidly and may need a booster before their same-age friends.
