Will only cover a mattress or a box spring, not both at the same time. Meaning you’d need to purchase an additional mattress bag if you also want to cover the box spring. Big enough to accommodate mattresses with built in pillow tops and deep (up to 15 inch) drops. Twin size covers work well for crib mattresses. Larger sizes may be used for protecting paintings and mirrors.
