We have just fitted our isofix base in car when we put base in to isofix points and put leg down to the floor as per instructions all indicators green but could lift base up from the front including leg off the floor same when car seat was on it definitely doesnt seem right, we then managed to extend leg out at more of an angle so it stayed put but that was only because the front of the base had then lifted off the cars seat and the baby car seat was wedged against back of the seat which again im sure shouldn't happen any tips or ideas on how to resolve please
