Don't worry, you're not alone. Many people use these terms interchangeably, but the truth is that they refer to two different types of bedding that serve different purposes.
Most sheet sets typically include a flat sheet, fitted sheet, and one or two pillowcases. There’s not much need for wondering if you need a flat or fitted sheet for this reason — both are useful and usually come as a package deal. Some other sheet sets, like those Casper offers, also include a duvet cover.

A duvet cover is the cloth case that encases your duvet and closes with buttons, snaps, or zippers. It is commonly made of cotton or polyester. It makes washing bedding simpler, gives more design flexibility, and even provides a distinct sensation beneath the covers.
