The Chicco OneFit LX is an all-in-one car seat for children 5 to 100 pounds that transitions from harnessed mode to booster mode as your child grows. In CR’s tests, the Chicco OneFit LX provides excellent crash protection and secure installation in both rear-facing and forward-facing positions and with either LATCH or seat belt installations. Adjusting the harness is simple, but adjusting the crotch strap means you’ll need to first remove the seat pads, cup holders, and buckle cover, which is not as ideal.
CR’s testers note that the seat is bulky and fairly heavy at 26 pounds. The seat’s weight has some drawbacks beyond making it harder to move the seat between cars, too: because the seat is on the heavier side, your child will only be able to use the seat inLATCH install mode up to 35 pounds in the rear-facing position, since the LATCH system has a weight limit that includes the weight of the car seat and the child rider.
This seat may be a good choice for:
- Families who want to purchase an all-in-one car seat (as opposed to using an infant seat for the first year and then switching to a convertible seat)
- Families who don’t need to move their car seat between multiple cars
- Anyone who needs a simple and straightforward installation, thanks to the push-on LATCH connectors and seat belt lockoff
