It protects the futon from bedwetting. It was completely fine for a little leakage. The pile fabric on both sides feels good against the skin. In winter, it can also provide warmth, so it might even prevent bedwetting itself. I am selling three of the same item, but the price difference is due to the frequency of use and the difference in fluffiness. I will offer a discount to those who purchase multiple items. Please understand that these are used items. Thank you.
