UPPAbaby owners have to check their exact model, because this is one brand where the answer changed mid lineup. The MESA V2 and MESA MAX expire 7 years after the date of manufacture. The newer MESA V3 jumps to 10. Two seats with nearly the same name, three years apart in lifespan. The expiration date is printed on the seat, so read it before you assume anything, and if you want the date checked a second way, enter the manufacture date into our Baby Car Seat Expiration Checker.
UPPAbaby Expiration Rules
- 7 years: the MESA V2 and MESA MAX infant seats
- 7 years: the ARIA and ARIA V2 infant seats
- 10 years: the MESA V3, the first UPPAbaby infant seat with a 10 year life
- 10 years: the KNOX convertible and the ROVE convertible
- 8 years: the ALTA belt positioning booster
MESA bases follow the same guidance as the seats they pair with, so a base does not get extra life of its own. One number to keep separate: UPPAbaby’s limited lifetime warranty runs up to 10 years from the date of manufacture for the original owner, with registration required within three months of purchase. That warranty covers defects. It is not a lifespan, and it does not stretch a 7 year MESA past its expiration date.
Where Is the Date on an UPPAbaby Seat?
The expiration date and the date of manufacture are printed on labels on the bottom of the seat shell, and on the base for MESA models. The serial number you need for registration and support is on the same label. Read the printed date rather than counting from when you bought the seat, because UPPAbaby counts from manufacture.
What If the Seat Has Been in a Crash?
The manuals are plain about it: discontinue use of the seat after a crash. UPPAbaby’s customer experience team reviews crash cases individually and can provide the documentation an insurer needs for a replacement. Call them at (844) 823-3132 with the crash details and your serial number before any crashed UPPAbaby goes back into service.
Can You Fly With an UPPAbaby Seat?
MESA infant seats are certified for aircraft use and install on the plane without the base, secured by the aircraft lap belt. The KNOX is certified in harness mode. The ALTA booster is not certified for aircraft, because boosters need a lap and shoulder belt. The certification statement is printed on each seat’s label.
UPPAbaby Expiration FAQs
When does the UPPAbaby MESA expire?
It depends which MESA you own. The MESA V2 and MESA MAX manuals say to stop using the seat 7 years from the date of manufacture. The MESA V3 manual sets 10 years. Check the labels on the bottom of the carrier and the base for the date that governs your seat.
How long do the UPPAbaby KNOX and ALTA last?
The KNOX convertible has a 10 year lifespan from the date of manufacture. The ALTA high back booster has an 8 year lifespan. Both print the governing date on the seat’s label.
Is the UPPAbaby MESA FAA approved?
Yes. MESA infant seats are certified for aircraft use and install without the base. The KNOX can fly in harness mode. The ALTA booster cannot, since it needs a lap and shoulder belt.
