Common questions
Which FAA-approved all-in-one car seats have the highest rear-facing weight limit?
The Britax One4Life ClickTight, the Evenflo EveryStage DLX and the Nuna EXEC list a rear-facing limit of 50 lb, the highest here. The lowest is 40 lb (the Graco 4Ever DLX 4-in-1, the Graco TriRide 3-in-1, the Chicco Fit4 4-in-1 and 4 more). These are the makers' printed limits; your child's height also has to fit.
How heavy can a child be in the forward-facing harness?
All 10 seats here with a forward-facing harness list 65 lb as the harness limit.
Up to what weight can these be used as a booster?
In high-back booster mode the maximum is between 100 and 120 lb; the Britax One4Life ClickTight, the Evenflo EveryStage DLX and the Nuna EXEC go to 120 lb. As a backless booster the maximum is between 110 and 120 lb. A booster also needs the seat belt to fit your child, so check the height range in the manual too.
How long do FAA-approved all-in-one car seats last before they expire?
The manuals list a useful life of 10 to 12 years. In the manuals we cite, it counts from the date of manufacture, which is printed on the seat's label. For 2 of the 10, the manual we cite gives no figure, so check the label on the seat. More by brand on car seat expiration.
