I am selling this item because the size didn't fit after I purchased it. There are some fold wrinkles. They should be no problem if ironed. ~The following is from the internet~ The DVALA box spring sheet is 100% natural cotton. It's made of a material that is breathable and absorbent, so it keeps you comfortable all night long. It becomes softer and more comfortable to the touch with each wash. Size: 120x200 cm
