What to know
The KNOX convertible has a 10-year lifespan from the date of manufacture, the longest in UPPAbaby's lineup.
The date of manufacture is on the seat itself. The expiration date and date of manufacture are printed on labels on the bottom of the seat shell and on the car seat base. The serial number needed for registration and support is on the same label.
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.
