For ages 9 months up to 4 years. These are the same chairs that were sold by Audi to fit in the back of a TT and other models. Both can be fitted either with the seatbelt or ISOFIX mounts if you have them. I have 2, one is in a black finish and the other in grey. Both from a smoke free home and never been in an accident. Both in great condition. £40 each or £70 for the pair collected, or arrange your own courier.
