【Manufacturer】R-Style I used this with a semi-double size futon. According to my purchase history, it's a double size, so it might also work for a double. Used a few times. Washed. I didn't see any noticeable stains or spots, but I apologize if I missed anything. It has elastic corners and is slightly wrinkled. This is a used item, so please understand. I plan to fold it compactly for shipping. Please be aware that there may be fold lines.
