Most commonly called a bed skirt or bed ruffle, this is a decorative piece of fabric placed between the mattress and box springs. It extends to the floor at the mattress's sides and bottom. Its main function is to hide the box spring, but bed skirts also add a touch of softness, color, and decor to the room.

Duvet covers often have buttons, ties, an envelope flap, or zipper as a closure to keep the insert enclosed. It should be noted that a Duvet is the insert that goes inside the Duvet Cover; usually comprised of down or a down alternative. When the insert and duvet cover are together, sometimes it is referred to as a Comforter. It is common for Duvet Covers to have finishing details like flanges or embroidery along the side and bottom edges only.
