Word of warning…
My Mother, Nan, saving money as usual, decided to buy one second hand a reasonably new Britix one, cost her a few notes, from gumtree.
I decided to check it over before she used it to transport our little one.
Glad I did, as the previous owner had removed all the strappings, I asume to clean it and in their wisdom used zip ties to secure the main seat belts back into the chair, as they could not work out how it all went back together!
Britex back then, would not supply parts to fix second hand seats, they ask for the seat to go back to them for checking, I know why they do that now. 😉
