Britax Marathon Vs. Sunshine Kids Radian
Are you trying to figure out which convertible car seat is better: The Britax Marathon vs. the Sunshine Kids Radian?
Good question! Both of these convertible car seats are favored by car seat technicians and parents alike. Below the images of these car seats are some facts to help you out with your decision:
- The Britax Marathon 70 is known to be easier to install than the Sunshine Kids Radian. If you are going to have your car seat professionally installed and then keep it there, this may not be a huge concern; however, if you might be switching your car seat between different cars regularly, then this will be an important factor in your decision.
- The Britax Marathon sits up on a base, which makes it higher than the Sunshine Kids Radian. This is great for younger children, but may be an issue with older — or taller — kids bumping their heads on the ceiling of a compact car when you are getting them in and out of the car seat. On the other hand, younger children appreciate being higher up, as it gives them better access to the view outside of the window!
- The Sunshine Kids Radian has an eight year expiration, vs. the Britax Marathon, which has a six year expiration.
- Both the Britax Marathon 70 has a rear facing weight limit of 40 lbs and forward facing weight limit of 70 lbs. The Sunshine Kids Radian 65 has a rear facing weight limits of 45 lbs, and forward facing weight limits of 65 lbs.
- The top harness height of the Britax Marathon is 17″, while the top harness height of the Sunshine Kids Radian is 18″. Since children generally outgrow car seats by height (rather than by weight), the extra inch of harness height means that the Radian will last you longer as your child grows taller.
- The Britax Marathon has more cushioning under the seat, and therefore feels more comfortable than the Sunshine Kids Radian.
- In compact cars, the Britax Marathon is far easier to install in the rear facing position. The Sunshine Kids Radian leans back more and therefore takes up more front-to-back space in the rear facing position, making it very difficult to install correctly in compact cars. (In the forward facing position, the Radian does not have this issue.)
- Parents reported receiving a better level of customer service via phone from Britax than Sunshine Kids.
- There is more leg-room for older children riding rear facing in the Sunshine Radian than the Britax Marathon, due to the design of the car seat.
- The Britax Marathon 70 (not the older, Marathon 65 version) does not require re-threading of the harness straps to raise or lower the height of the harness straps, unlike the Sunshine Kids Radian. If you will regularly be using your car seat for play dates and carpools, this can be a significant consideration. If you will only use the car seat for your own child, then you’ll probably only need to adjust the harness straps height every couple of weeks or months.
- The Sunshine Kids Radian can fold up when not in use to save space, which is a tremendous convenience if you will be doing a lot of traveling out of your the car. (i.e. on airplanes, trains, etc.) The Britax Marathon cannot be folded.
