Chicco lists this seat on its US site. Buy from Chicco or an authorized retailer, and confirm the exact model number before you buy.
This seat covers 3 stages, and a child has to meet every limit of the stage they are in. Check the date label on the shell before using a hand-me-down; every seat has an expiry.

| Mode | Child weight | Child height | Minimum age | Conditions |
|---|---|---|---|---|
| Rear-facing harness | 5 to 40 lb | Up to 43 in | Not published | Manual: newborn insert/positioner for 5-11 lb. |

A child must meet every limit for the mode they use. The labels on your seat and its manual are the final word.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.

At 16.7 in at its widest, this seat is one of the narrower ones in its class and is a candidate for three across in many mid-size cars. It weighs 21 lb, which matters if you will move it between cars or carry it through an airport.

No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.
