What to know

The AACE is a belt-positioning booster, high back from at least 4 years old at 40 to 110 pounds and backless from at least 5 years old at 50 to 120 pounds. Its manual says not to use the booster if it is more than 10 years old, and tells you to check the manufacturer label or the stamped do-not-use-after date on the bottom of the booster. Ten years is longer than the 7 Nuna gives its PIPA carriers, which is normal: a booster is a much simpler structure than a harnessed seat. The manual is blunt that this restraint is not certified for aircraft use, so the AACE stays home when you fly.

The date of manufacture is on the seat itself. The model number, date of manufacture, and stamped do-not-use-after date are on a label on the bottom of the child restraint (and on the underside of the base for seats sold with one). Nuna also prints this information on the registration card packed with the seat.

Safety note: SeatCheck summarizes manufacturer and NHTSA guidance, but the label on your own seat and its manual are the final word. When in doubt, contact the manufacturer with your model and serial number.

Frequently asked questions

How long is the Nuna AACE good for?
The Nuna AACE has a useful life of 10 years from its date of manufacture. The exact date is printed on the seat's own label, so check the sticker on the shell or base rather than counting from the purchase date.
Where is the expiration date on the Nuna AACE?
The model number, date of manufacture, and stamped do-not-use-after date are on a label on the bottom of the child restraint (and on the underside of the base for seats sold with one). Nuna also prints this information on the registration card packed with the seat.
Should I replace the AACE after a crash?
Nuna's US manuals reproduce the NHTSA criteria: never use a seat that has been in a moderate or severe crash, while a seat may continue in use after a minor crash only if the vehicle drove away, the door nearest the seat was undamaged, no one was injured, no airbags deployed, and the seat has no visible damage. Nuna also says to stop using a seat with frayed straps or damage from any crash and to call 1-855-NUNA-USA with questions.
