We are selling our Clek car seat because our daughter has grown out of it. The expiry date on Clek fllo seats are 9 years from manufacturing date (they outline this on their website here towards the bottom of the page https://clekinc.ca/products/fllo#:~:text=Warranty%20registration%20card-,Safety%20Standards,has%20a%209%20year%20expiration.) This seat was manufactured in 2017 (I have attached a photo of the manufacturing date on on the seat) so has four years left before expiry). The seat is in good condition and has never been in any accidents.
