A Japanese futon can be the mattress underneath the sleeper or the quilt above. Used with a pillow and covers, foldable bedding can be put away so a room serves other purposes during the day.

Different pieces do different jobs
The mattress and the quilt
The shikibuton lies beneath the sleeper, the kakebuton covers them and a pillow supports the head. Under-bedding has to bear and distribute body weight; a covering quilt needs to fit around the body and retain warmth. Those jobs need not call for identical firmness, thickness or fillings.
The Japan Futon Association describes one modern three-layer mattress with a firmer polyester or wool core between cushioning layers, intended to reduce the feeling of bottoming out. It is one construction, rather than the hidden structure of every futon. Futon bedding can also be used on a bed.

The shell is different from the cover
The shell contains the filling; a removable cover is a separate layer placed around the finished bedding. Cotton, wool, down, synthetic fibres and blends have different properties, so the filling label is more informative than the pattern on the cloth.
Japanese mawata is silk floss, not cotton. Down forms fine clusters that hold air, while feathers have a curved shaft. Their proportions and the quantity of filling are part of the product’s construction; a fluffy appearance alone cannot distinguish a down quilt from feather bedding.

What loft contributes
Warmth depends on more than the weight of stuffing. Air held between down clusters creates an insulating layer, allowing a light filling to occupy considerable volume. Compressing the quilt under a heavy object reduces that loft.
Cotton’s natural twists and hollow fibres contribute elasticity and thickness when layered, and the material absorbs moisture. Absorption does not mean that moisture has left the bedding: cotton releases it comparatively slowly. Drying therefore matters to loft as well as storage. Support below the body and light, conforming warmth above are different requirements.

Putting bedding away takes more than folding

Recovering a room for daytime use
The underside of floor bedding has little exposure to moving air. Folding it immediately with the covering quilt can carry retained moisture into storage. Turning back the quilt first exposes the bedding; lifting the floor-facing surface then allows it to dry by a method suitable for its material. A foam mattress may be stood up for ventilation according to its maker’s instructions; prolonged direct sunlight is not a universal solution.
Once dry, fold the bedding into a dry cupboard. Heavier under-bedding goes below lighter covering quilts, protecting the latter’s loft. The room can then serve daytime activities. Clearing the floor is a sequence of airing, drying and storing, rather than folding alone.

Care depends on the filling
First identify whether you are cleaning the removable cover or the filled bedding. A washable cover follows its own label; washing or machine-drying the filled item is a separate question. Shell fabric, quilting and filling combinations can alter the instructions even within the same material category.
The Japan Futon Association distinguishes ventilated shade drying for silk-floss bedding; Nishikawa likewise recommends shade drying for routine down care and ventilation of a foam mattress’s underside. Hard beating can damage cloth and filling. Loose surface dust can be brushed or vacuumed away as appropriate to the product.

What cotton reworking changes
Cotton layers can become compacted under repeated use. Uchinaoshi mechanically loosens that mass. The process can also shorten fibres and reduce the amount of filling, so reworking may add new cotton and replace the shell before the bedding is made up again.
It differs from airing a quilt, and cannot restore a damaged fibre to its original length. Whether to rework an item depends on its condition; one fixed replacement interval does not describe every futon.

From mats and clothes to padded night coverings
The ICU Museum’s exhibition account describes sleeping on mats under everyday clothing or coverings called fusuma (衾), before cotton-filled bedding became widespread. Large garment-shaped padded yōgi appeared in the Momoyama period. They covered the sleeper without the arms entering the sleeves; a collar fitting the neck and shoulders reduced gaps.
The museum’s yōgi with crane-roundel and drum motifs dates to Meiji–Taishō. Its collar, broad sleeves and spreading lower section make that garment-like outline visible.

Bedding cloth could reuse smaller pieces
The exhibition also shows part of a yosegire bedding cloth, with pieces in blue, grey and other tones joined into a larger surface. Its account places reused scraps alongside bedding cloth made with paper yarn, kasuri, stencil dyeing and freehand resist dyeing.
The example makes the outer cloth part of bedding’s material history: available pieces and their arrangement help form the larger item.

Regional changes before the ready-made trade
Expanded Edo-period cotton cultivation did not make filled bedding an inexpensive possession for every household; it could remain a substantial bridal purchase. The ICU account describes large rectangular quilts replacing yōgi in Kansai from the middle Edo period, while smaller kaimaki remained in use longer in Kantō and Tōhoku. Forms and timing varied by region.
Ready-made retailing changed another part of supply. Nishikawa records its Osaka shop taking up futon in 1887, followed by its Tokyo shops. Selling winter bedding complemented the company’s summer mosquito-net trade. This documents one retailer’s seasonal business, not a simultaneous nationwide replacement of older bedding.
New fillings and several ways to sleep
Nishikawa records a synthetic-filled Tsukijirushi Rose product in 1956, promoted as avoiding traditional cotton reworking. Its Rose Mitchy, introduced in 1959, was a different product with a shell that could be removed for washing. One change concerns filling; the other concerns access to the outer fabric for maintenance. The shared brand name does not make them the same model.
Cotton, wool, down, synthetics and foam still coexist, alongside floor bedding and beds. English furniture usage can also call a sofa bed a futon, but its frame is not required by the Japanese bedding term.
New fillings travelled through retail networks
A separate Nishikawa account records synthetic filling developed by the former Nishikawa Sangyō in 1958 and a long-fibre polyester developed with a German company in 1970. In 1960 it also established a retail chain from an existing group of trading partners, supporting member shops with sales, promotion and information.
The example connects material development, retail purchasing and household selection. A new filling reached users through products and distribution, rather than through fibre invention alone.
Check your understanding
What different jobs are done by a firmer mattress core and a lofty covering quilt?
The core supports the sleeper and reduces bottoming out; air held in the quilt’s loft contributes insulation.
Why does moisture-absorbing cotton still need drying?
Absorbed moisture has not automatically left it; comparatively slow release makes drying important to loft and storage.
Does a washable cover establish that its filled bedding can be washed the same way?
No. Check the cover and filled item separately; shell, quilting and filling affect treatment.
What happens between waking and putting floor bedding in a cupboard?
Turn back the quilt, expose and ventilate the underside, dry appropriately, then fold into dry storage.
Can uchinaoshi restore damaged fibres to their original state?
No. It loosens compacted cotton and may add fresh filling and replace the shell.
How was garment-shaped yōgi used, and when was this example made?
It covered the sleeper without the arms entering its sleeves; the illustrated crane-and-drum object is Meiji–Taishō.
How did futon complement Nishikawa’s seasonal trade in 1887?
Winter bedding complemented a business concentrated on summer mosquito nets.
What distinguishes the 1956 Rose product from the 1959 Rose Mitchy?
The 1956 product used synthetic filling; Rose Mitchy added a removable washable shell in 1959. The displayed image shows the latter and is itself undated.
