I purchased this from a brochure introduced by a care manager for in-home care for a family member. However, instead of covering the entire mattress with a sheet, I ended up using partial sheets (inspired by a visiting nurse's suggestion to use pet sheets for dogs). Therefore, I didn't use this item and it remains unused and unsoiled. It says, "Quickly absorbs moisture and keeps the surface dry for comfort." I think it's a good idea to use this as a preventative measure not only for nursing care but also for families with young children. For those who prefer natural materials against their skin, you could cover this sheet with a 100% cotton sheet. ● Size (width x length): 93 x 194 cm ● Material: 100% polyester ● Color: Green (the color in photo 4 is the most accurate) ● Machine washable, spin dry, and dryer safe (below 80°C) ● Compatible with both 83cm and 91cm widths ● Suitable for mattresses with a thickness of 8cm to 18cm Price: 6600 yen Made by Frontier Co., Ltd., a company specializing in nursing care supplies. I thought I might be able to use it as a general bed cover, but I prefer a smooth cotton sheet for that purpose. So, I'm offering it to anyone who needs it. *Please understand that this is a used item stored at home before purchasing. *Shipping via Yu-Yu Mercari Bin (Yu-Pack 60 size).
