Thank you for viewing. This item was purchased online. I am selling it because I didn't particularly like the feel of the fabric. After the product arrived, I attached it to the mattress once to check the size, but it has not been used. The size is 120 x 200 x 27 cm, and the width is slightly larger than the standard size. Although it is unused, I have cleaned it at home since I attached it once. Thank you.
