Bed dress is a term used for the bedding used to cover mattresses, which is also known as a bedspread or bed cover. Synonyms for bed dress include quilt, coverlet, bedspread, comforter, and duvet. Quilts are typically made of layers of fabric and provide warmth. Coverlets are lightweight and used for decoration. Bedspreads are designed to cover the entire bed and often hang down to the floor. Comforters are a type of bedspread filled with synthetic material or natural down. Duvets are similar to comforters but are typically filled with feathers or down and have a removable cover that can be washed. No matter which synonym is used, the goal is to enhance the look and comfort of the bed.
