A practical item that doubles as storage and interior! I would like to introduce the idea of Daiso's "storage bag that transforms into a cushion" that is used for packing bedding.
The one I found was a storage size of 55 x 55 x 20 cm, 400 yen (excluding tax). The price is high at the store, but it is quite reasonable compared to similar products.
A soft cotton-blend material is used for the side fabric, giving it a silky feel. You can stuff the contents by opening the fasteners on the top three sides. I could store about 5 blankets and rugs, and 1 off-season kotatsu futon (185 cm square).
The size of the cushion allows you to comfortably store your body, making it ideal for sleeping pillows and backrests. With a handle, it is easy to move.
It can be used as a storage bag even when it is not used as a cushion, so it is an item that seems to be flexible if you have it. If you are considering a large bead cushion, why not try using your own futon first?
