Futon

Before recycled cotton cloth was widely available in Japan, commoners used kami busuma, stitched crinkled paper stuffed with fibers from beaten dry straw, cattails, or silk waste, on mushiro straw floor mats. Later, futons were made with patchwork recycled cotton, quilted together and filled with bast fiber.^[4] Later they were filled with cotton. Wool and synthetics are now also used.^[5]

Yogi (よぎ, literally "nightclothes") are kimono-shaped bedclothes. They were used in the 1800s and early 1900s.^[6] Rectangular kakebutons are now widely used. Kakebutons vary in materials; some are warmer than others. Those with traditional cotton filling feel heavier than those with feather or synthetic fillings.^[5]

Traditional makura (まくら) are generally firmer than western pillows.^[5] They may be filled with beans, buckwheat chaff,^[5][7] bran,^[8] or, modernly, plastic beads,^[5][7] all of which mold to the head. Historically, some women used wooden headrests to protect their hairstyles.^[6]

Futons are traditionally laid on tatami rush mats,^[7] which are resilient and can absorb and re-release up to half a liter of moisture each.^[9] Tatamis measure 1 by 0.5 ken, just under 1 by 2 meters,^[10] the same size as a Western twin bed. A traditional shikibuton is also about the size of a Western twin bed. As of 2010^[update], double-bed-sized shikibutons were available, but they can be a bit heavy and awkward to stow.^[5]

The shikibuton is usually 2–3 inches (5–8 cm) thick,^[7] and rarely as much as 6 inches (15 cm) thick; they need to dry well, or they will become heavy and mouldy.^[5] A shikibuton is thus about as thick as a Western mattress topper.^[11] If more thickness is needed, shikibutons are layered.^[5]

Kakebutons may be wider than shikibutons,^[12] and they vary in thickness. Depending on the weather, they may be layered with a warm mōfu (毛布), or replaced with a lighter taoruketto (タオルケット).^[7]

The traditional makura is usually smaller than a western pillow.^[5]

In the 1980s, futons became fashionable in North America.^[13] The construction method was similar to that of contemporary Japanese futons: cotton batting, covered in cotton ticking and held in place with hand-sewn tufting (through-thickness stitches).^[13] This was also the structure that had been used in the United States' 1940-1941 Cotton Mattress Program, designed to use excess cotton production by subsidizing materials for people to make their own cotton mattresses.^[14][15]

However, Western-style futons, which typically resemble low, wooden sofa beds, differ considerably from their Japanese counterparts.^[1][16] They often have the dimensions of standard western mattresses, and are too thick to fold double and stow easily in a cupboard. They are often set up and stored on a slatted frame,^[13] which avoids having to move them to air regularly, especially in the dry indoor air of a centrally-heated house^[17] (most Japanese homes were not traditionally centrally-heated^[18]).

Traditional European beds resembled Japanese-style futon sets, with thin tick mattresses. These were only sometimes set on a bedframe. The term "bed" did not originally include the bedframe, but only the bedding, the same components included in a Japanese futon set.^{[19]: 674–5 vol1}

It was also traditional to air these beds, and duvets are still aired in the window in Europe. In English-speaking cultures, however, airing bedding outdoors came to be seen as a foreign practice, with 19th-century housekeeping manuals giving methods of airing beds inside, and disparaging airing them in the window as "German-style".^[20]
