A bedroom lives or dies by its bed. Everything else in the room can be working hard and it will not matter if the bed looks like an afterthought. We have spent more time than we care to admit thinking about duvet covers specifically, because they cover more surface area than anything else in the room and most people are settling for ones that pill after six washes or feel scratchy against skin or photograph well but sleep terribly. The cover that earns its place does both jobs. It looks considered at ten in the morning when the bed is made and it feels good at eleven at night when it actually matters. We have been looking at weave, weight, how the fabric behaves after repeated washing, and whether the buttons or ties are the kind that hold rather than give up quietly. Percale for crispness, washed cotton for that relaxed broken in feel, linen for converts who will not go back. These are the ones worth making your bed for.
