Do I need special bedding for a 160x220 cm mattress?
Yes, because 160x220 is a long size. Choose a fitted sheet of 160x220 cm, or a stretch fitted sheet that is explicitly suitable for a length of 220 cm. A 240x220 cm duvet fits well. If you each want your own duvet, choose two duvets of 140x220 cm. A Tuur® mattress protector and topper are also available in 160x220 cm.
