I'm puzzled by the couple of threads at the moment about car seat fitting.

We don't own a car, but we do regularly use a car sharing service, where you book one of the cars that lives nearby, by the hour or day, and only pay for it for the time you use it. I guess we use a car about once a week, at the moment.

We haven't bought a car seat yet, but I have been assuming that they are relatively easy, at most a few minutes work, to fit, and to move from car to car. We don't use the same car all the time and we can't leave a car seat in one of the share cares anyway, so we'll have to be able to move our car seat into whatever car we are using that day.

Is this going to be a problem? I'm dismayed by the thread talking about people getting their car seats professionally fitted - surely it can't take as long, or be as difficult as all that?

Is there stuff I don't know about car seats?

Can anyone recommend a seat that fits into a small car (the share cars are mostly honda jazz's), and can easily be fitted and removed?
