Can two 80x220 cm mattresses be used in a double bed?

Yes, two 80x220 cm mattresses placed side by side fit a 160x220 cm double bed frame. The advantage of two separate mattresses is that each partner can choose their own firmness independently, and each mattress is easier to rotate than a single wide one. A Tuur® topper in 160x220 cm bridges the gap between both mattresses, creating one seamless sleeping surface.
