This seat covers 2 stages, and a child has to meet every limit of the stage they are in. Britax gives it a 10-year life from the date of manufacture, so check the date label before using a hand-me-down.

| Mode | Child weight | Child height | Minimum age | Conditions |
|---|---|---|---|---|

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 17 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.

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.
