Many vehicles come out of the factory with the urban driver in mind. If your driving involves long hours behind the wheel, or bumpy conditions then you will probably start to feel quite uncomfortable before too long, eg. Landcruiser 75 and 78 series utilise a 2 seater bench seat
with absolutely no side support to stop you rolling around, particularly in offroad conditions.
Planning a Long Journey
If you are about to travel around the continent for a few months then it would certainly be a worthy investment to take a look at what alternatives you have for improving the seats in your vehicle. It's fair to say that any seat
will get uncomfortable after a few days of continuous driving, but if the seat
can be adjusted to shift your weight, even marginally, the effect can be quite astonishing - and this is one of the features to look for in aftermarket seats.
