If you like the current mattress size you’re on, then don’t change it.  If you’re changing lifestyle (e.g.marriage, pregnancy, retirement), you might be thinking of increasing or decreasing the size of your mattress.  If you find that your partner disturbs you during sleep, one solution might be to upgrade to a larger mattress.
