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. 

Solid designs are a fantastic choice if you already have a detailed bedroom décor and only want to add a burst of color to the area. If you want a duvet cover that will be used to decorate the entire bedroom, intricate designs such as branches, flowers, and stripes may be desirable. The use of embellishments like pleats add visual interest. Some duvet covers are reversible, featuring a distinct pattern on either side of the cover. Reversible duvet covers allow you to change the look of your bedroom quickly and easily without having to buy additional bedding pieces.
