The Amherst bed set is where casual meets contemporary. The clean color lines of this set make it simple in a way that you can accessorize any way you want. Sleek piping of the fabric on the duvet cover and pillows gives a strong visual dimension and ties the whole bed together. In addition, there is a floral pillow that adds a softness which is different from the manipulation of fabric and colors on the rest of the set. A duvet cover is a protective cover for your comforter, most likely for your down comforter. Sometimes it's referred to as a comforter cover. Duvet covers are not filled. It has an opening where you can insert your comforter. Filler not included.
