This is an organic futon from the manufacturer Wataya Mori. I used it for one season. I am selling it because I am replacing it. I purchased it for around 40,000 yen. I used it with a cover from the beginning, so I never used it without one. The thickness has decreased considerably, so I recommend using it with something else underneath. Although there is a feeling of use, the material is of very good quality, so you can use it with confidence. It's a great deal with a cover included. (^^)
