A duvet set comes with a duvet cover and pillowcase/s or shams. Our Saatva duvet sets come with matching shams which are designed to be more decorative and placed over your duvet cover.
Depending on the size, a duvet cover set comes with one standard/queen pillowcase or sham for Twin & Twin XL, or two Standard/Queen or King size pillowcases or shams for Queen and King/Cal King.
