Why more people are giving up on duvet covers for good

Ask around and you hear the same thing: the duvet is the worst part of changing the bed. Turning the cover inside out. Hunting for the corners. Arms up over your head, shaking until it finally sits right.

For a lot of people it has quietly become a two-person job, or a job that gets put off for another week.

A duvet cover exists because ordinary duvets are hard to wash. They're bulky, they take ages to dry, and the filling moves about. So we wrap them in a bag and wash the bag instead.

The cover gets washed every week or two. The duvet underneath, about twice a year, if that.

The One-Piece Duvet™ from Straight to Bed, who paid for this article, is duvet and cover in one. You lay it on the bed and smooth it out. That's it.

When it needs a wash, the whole thing goes in your washing machine at home at 30°C. The filling sits in BoxLock™ chambers closed on every side, so it stays where it belongs, wash after wash.

Strip it, wash it, back on the bed. No cover to wrestle on, no corners to find, nobody to call for help. It comes in five sizes and nine colours, with two matching pillowcases free and 100 nights to try it at home.
