Thank you for viewing. This is a single-size waterproof sheet. I used it on my child's bed for several years, but I removed it and stored it at home because I didn't need it anymore. It was attached to the mattress, so the elastic is a bit worn and coming off in one place. - Color: Pink - Material: Waterproof material - Condition: Elastic is coming off Antibacterial and deodorizing treatment for peace of mind. Dryer and spin dry safe.
