This is a waterproof sheet for caregiving, designed to cover the entire bed with rubber and hooks. According to my own measurements, it's about 100cm x 200cm. I used it for about two years, but I have several of this size, and I used a smaller sheet on the area of the lower back, which tends to get dirty, so I think the frequency of use was low. The rubber isn't stretched much either. It's also designed to be fastened with hooks, but we didn't use that part at home. If you don't mind that it's used, how about it? Shipping costs 60 size, so I can't lower the price much. Most of the price is the shipping cost. Depending on the item, I welcome discounts for multiple purchases. I also want to sell it quickly, so if you need more than one, please let me know.
