Please contact me via comments beforehand! This is a double-size waterproof sheet. It has elastic bands on all four corners, so you can hook it onto a futon or bed mattress. The back side is made of waterproof material. It can be used for various purposes, such as for children, caregiving, and pets. This is a used item, so please understand and purchase with no claims and no returns. (I used it to prevent pet bedwetting, but there were no accidents.) There are a few stains (2-3 spots) from color transfer during washing. Please check the images. (They are a light brown color.) Sheet color: Pale yellow
