Futon is a mattress type that originates from Japan and other eastern countries. Futons mattresses are usually filled with cotton or wool. Though some have also more exotic fillings such as latex layers in them. Compared to usual mattresses, futons are much less soft. Because they don't give up under body weight, many say that they are better for your back. Some also like them better for sex as they give better support.
Futons can be used with almost any interior design, but they are probably best for simplified Japanese styling:
Because futons don't have springs or other complex parts, they can change shape. Usual Japanese style is to roll mattress away from bed after waking up and hiding it into a closet - great way if you're tight on space. Futons are also great for quest room or for sofa-bed.
