What to know

Evenflo's FAQ names the Symphony as one of the exceptions to its old 6-year rule and gives it 8 years from the date of manufacture, because it is an all-in-one used from infant seat through belt-positioning booster. Read the date of manufacture label on the seat: units made from January 2025 on fall under Evenflo's newer 10-year policy.

The date of manufacture is on the seat itself. The date of manufacture label, which also shows the model name, model number, and expiration information, is usually on the bottom, side, or back of the seat. On infant seats check the underside of the carrier and the base.

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 Evenflo Symphony good for?
The Evenflo Symphony has a useful life of 8 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 Evenflo Symphony?
The date of manufacture label, which also shows the model name, model number, and expiration information, is usually on the bottom, side, or back of the seat. On infant seats check the underside of the carrier and the base.
Should I replace the Symphony after a crash?
Evenflo instructs owners to replace a car seat after any crash, regardless of severity. It does not apply the NHTSA minor-crash exception. Buyers of Evenflo Gold products also get an accident replacement program through the ParentLink consumer care team.
