This product is NOT Japanese traditional futon.
It is made by machines, not by a Japanese craftsman.
Extra Cotton-Padding Type
A heavy, 5kg Japanese-style mattress with a solid cotton filling.
It’s extra-thick, so just one is all you need for a great night’s sleep!
(The market standard is about 3kg.)
These futons have been made to capture the best qualities of wool futons, while improving their durability, elasticity, and thickness.
The secret to the firm, body-supporting thickness is the three-layer design, in which solid cotton is sandwiched between two layers of wool fiber.
