OK, that's good to know. I was worrying that we might not be able to use a car at all, if it was impossible to move them around once fitted.

I do think we'll just have to get good and fast at it. At least we'll be fitting it to the same kind of car all the time (or nearly all the time), so the adjustments should be the same.

I am planning to get a combo rear/front facing seat, and use it in the rear-facing position for as long as possible, because I read it's safer. Don't want to spend a load of money on something we'll not use often, though, that's why I want to get the combination one.
