What bedding do I need for a 150x200 cm mattress?
For a 150x200 mattress you use a 200x200 cm duvet, just like for a 140x200 or 160x200. Fitted sheets in exactly 150x200 are less common, but a stretch fitted sheet for widths from 140 to 160 cm usually fits well. Do check the maximum mattress height on the label.
