*This is a futon for autumn and winter. It can be attached to Usa-Dan M (body size 16x23) and won't slip because it has rubber bands. *Size (Usa-Dan M body 16x23) 18x25 (hidden part entrance 26x18) The entrance has a gusset and is made wide, so I think up to two animals can fit. The pattern can be changed (I have a confirmation listing, so you can see the fabric patterns there and change them). If you can't find it, please comment. I will put the fabric patterns in the second photo after creating a dedicated listing. If you want two or more, please comment first. 2-piece set: 100 yen off 3-piece set: 150 yen off 4-piece set: 200 yen off Up to 4 futons can be shipped together. *Can also be made in a horizontal type.
