Should I choose one 200×200 mattress or two separate 100×200 mattresses?

If you and your partner have different sleep preferences, two separate 100×200 mattresses are a smart alternative, as each person can choose their own mattress type and firmness level. One 200×200 mattress is the better choice if you both share similar preferences and want a seamless sleeping surface without any gap in the middle. Two 100×200 mattresses give each sleeper full independence. A split topper placed on top can bridge the gap between two separate mattresses for a uniform feel.
