Drycleaning is costly and not very environmentally friendly. I can only guess how much chloro-fluorocarbon liquid is required to dry clean my double duvet, twice a year. The whole process of using volatile organic solvents in this way seems like a good way to kiss what’s left of the ozone layer goodbye.
Today’s invention provides a way to wash the said item in a domestic machine. Double duvets would be formed by poppering together, lengthways, two slightly wider than normal single duvets so that one overlaps the other down the centre of the bed. This unit would then be placed inside an outer cover and poppered in place around its internal periphery.
This would allow almost all the flexibility and thermal comfort of a traditional duvet, whilst allowing each ‘half’ to be washed separately.
