#1 Britax One4Life Clicktight
Britax’s One4Life convertible car seat – like other convertible car seats – can be used from the time of birth until your child uses the regular shop seat. But unlike most other cars, Brita’s One4Life has a different advantage: ClickTight’s company installation system, which is foolproof and ensures the right installation.
#2 Graco 4Ever DLX
True to its name, the Grace 4Ever DLX 4-in-1 car seat is designed for kids in terms of small storage space that is only 4 to 120 schoolgirls. Its four modes – the rear-seat car, the front-seat car, the high-pressure rear, and the rear booster – mean you will never buy your child a second car seat.
This car seat grows with your child by providing six different seating positions, as well as ten different positions.
#3. Evenflo Symphony DLX
This adjustable car seat is transformed from a car seat capable of keeping a newborn pound safe, to a forward-facing car seat and moved boostered.
#4 Cosco Scenera Next
The next Cosro’s Next is a small, adjustable lightweight car seat, boasting enough to fit three-in-a-row in most cars. Also, for those who love the country, Cosco insists Scenera Next is produced in Indiana, USA.
#5. Graco Extend2Fit
Graco’s Extend2Fit is a convertible car seat that allows babies and toddlers to ride backward or forward. Not once, however, does it change from car seat to booster.
This chair is not listed in the Consumer Reports list, but the rear weight limit is 50 lbs – higher than the other few seats, and allows children to sit back for longer. It does not limit the length of the back, however, except that the baby’s head needs to be at least 1 ″ “under the red handle.”
Forward, the seat is suitable for infants and toddlers weighing between 22-65 lbs (9.98-29.48 kg) and 124.5 inches high.
#6. Diono Radian 3RXT
A smaller seat like the Clek Fllo, Diono’s R-All-in-One Rionan 3RXT allows parents to fit three car seats in the back row. Unlike the Clek, this seat can be used as a rear-facing car seat, front-facing car seat, and a high-rise passenger (with no harness).
#7. Chicco NextFit
Rated Consumer Report’s top pick, the Chicco NextFit is a convertible car seat given a crash protection of “best,” and its SuperCinch easy-installation feature makes LATCH installations easier.
Though this is a popular and well-loved car seat, it does not convert to a booster seat – something reflected in its forward-facing weight limit.
#8. Britax Marathon ClickTight
As a car seat that can rear-face or forward-face (but doesn’t convert to a booster), Britax’s Marathon ClickTight has everything going for it: easy installation for both forward- and rear-facing positions, an anti-rebound bar which can be bought together with the seat, a no-rethread harness, and a crash protection rating of “better.”
#9. Clek Fllo
The convertible Clek Fllo convertible car seat offers a few important safety features: anti-backlash bar, locking doors, easy installation, and consumer protection crash rate “better.”
Simply put, this Clek is also a star: Although the seat is heavy, it is narrow and can easily fit in the back row with another spray or car seat. Also, Fllo is easy to clean, soft, and very comfortable when touched.
