You really can only answer this yourself. you might have a 'bogstandard' bed, or a superdooper de luxe model from Harrods; you might have a sound system in your living room, as opposed to a portable tv set.
Its not rocket science to get a bit of paper/calculator and walk from room to room putting a value on all the contents.
Then add something for clothing - again depends on shopping habits - Pennys/Dunnes or BT. Add for kitchen utensils, any books/cd's/dvd'd/ toys etc.
If all was bog standard then you are probably not under insured at €50/60K on contents.
