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. 

Bedskirt

Warmth Brushed Cotton Bedding

To get the best night's sleep possible, you need bedding tailored to your specific sleeping type. While a duvet and comforter may be similar in appearance, the duvet is a distinct top layer that can easily be swapped out each season. Because it is a covering, duvet covers are often mistaken with other types of bedding, just like bedsheets are.

 To complete the look, consider adding a bedskirt to hide the space under your bed for a clean, uncluttered look.  This accessory can also add a decorative touch, especially if it has frills or ruffles.
