We were given this seat to use for our grandson when he was five and have never explored all the configurations for smaller children so there’s no guarantee everything works. However, it was in good condition when we received it and it appears that the previous owners looked after it so I would expect everything to be OK. I don’t know how old it is. It comes with the manual.
