This is a cover for a futon mattress. It's unopened, but I purchased it a while ago and have been storing it at home. Since it's unopened, I haven't been able to check for small stains, etc. If you understand this, I would appreciate it if you would consider purchasing it. When shipping, I will take it out of the bag and fold it up to make it smaller. - Size: 125cm x 215cm - Material: 80% polyester, 20% rayon - Usable: Fully openable - Washing: Machine washable Thank you for looking.
