Futon is Japanese traditional furniture, basically a mattress that makes up a bed which is still commonly used today. Futons first appeared as weed-made rags in ancient Japan. A traditional futon set usually costs under 10,000 yen (around$83) sold at specialty stores called futon-Ya in Japan and other department stores https://m.post.naver.com/viewer/postView.naver?volumeNo=39273764&memberNo=23371807
