Mattresses come in different thicknesses, which can affect the way linens fit, especially fitted sheets and mattress pads. An average size for the comforters for a queen-size bed is 90-inches wide by 94-inches long, though some variation in comforter dimensions exists.
Queen-size hard-side waterbed mattresses are slightly longer than traditional mattresses, but the width is the same. A queen-size waterbed mattress measures 60-inches by 84-inches. Soft-side waterbed mattresses have the same dimensions as a foam or innerspring mattress.Learn more about Beds & Mattresses
