A 2-in-1 booster seat with 2 modes: high-back booster 40 to 100 lb, 43 to 57 in; backless booster 40 to 110 lb, 43 to 57 in.
NHTSA lists a campaign naming this model family (16C004000). I pause shopping links until I have read the campaign and checked which build dates it covers.
This seat covers 2 stages, and a child has to meet every limit of the stage they are in. Graco 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 |
|---|---|---|---|---|
| High-back booster | 40 to 100 lb | 43 to 57 in | 4 years | At least 4 years old (manual) |
| Backless booster | 40 to 110 lb | 43 to 57 in | 4 years | At least 4 years old |
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 19.69 in at its widest, measure your back seat before counting on three across. It weighs 11.73 lb, which matters if you will move it between cars or carry it through an airport.

When they differ, follow the manual and the labels on your seat.
NHTSA currently lists one campaign naming this Graco family: 16C004000. A campaign names a family, not always every build, so check your seat’s model number and date of manufacture against the campaign itself.
I have not reviewed these campaigns for this model yet, so shopping links stay paused here.
