Water breaking preparation...?

I'm a first time Mum, have hear lots of stories about waters breaking some slow 'leak', some hear a 'pop' then gush, some it happens in the car, on the couch, on the loo, in bed, at work... my question is;
Is it worth putting disposable change mats on the car seat/couch/bed to protect fabrics?
Probably sounds like a strange question but it's something I've been thinking about
