Useful life
—
10 yrs from manufacture
Chicco KidFit ClearTex Plus: From the Chicco KidFit Plus manual (ClearTex = fabric only, same limits). The 44–57″ height is the seat's stated overall range; weight differs by mode (highback 40–100 lb, backless 40–110 lb). Useful life is set by a “Do Not Use After” date on the label.
Nuna AACE: Belt-positioning booster convertible between high-back and backless mode — the two modes have genuinely different weight floors and minimum ages (high-back: 40 lb / 4y+; backless: 50 lb / 5y+), same height range for both. Do not use if more than 10 years old (printed number, per manual).
That is the record of the brand — not a verdict on these models. A recall names specific models and manufacture-date ranges, and a seat missing from the record is not "recall-free": check nhtsa.gov/recalls with the model and date of manufacture on your seat's label.
