Choosing a duvet cover or comforter

A duvet cover slips over a separate insert and is easy to wash on its own; a comforter is one filled piece, best suited to guest rooms or a simpler bed-making routine. Thread count and fabric weight are a better fit guide than count alone: cotton percale suits warmer nights, brushed cotton or flannel adds weight for winter. Check the size guide before buying, single through king, as duvet cover and fitted sheet sizing can vary slightly between brands.
