Japanese shikibuton, made in Japan.
A shikibuton is a foldable Japanese sleeping surface: laid out at night, aired and folded by day, and cared for as part of the room rather than left permanently sealed against the floor.
Shikibuton, not sofa bed
A sleeping layer built for floor-level living.
In British English, “futon” often means a convertible sofa. A Japanese shikibuton is different: it is the mattress layer of futon bedding. It rests on tatami, a suitable platform, a ventilated frame, or a carefully managed hard floor, then folds for airing and storage.
Airflow
Lift, fold, or stand it regularly so moisture does not remain trapped underneath.
Measured space
Choose from exact centimetre dimensions, not assumptions based on Irish mattress labels.
Two models · One atelier

Visit our workshopMoisture routine
The floor is part of the bedding system.
Warmth and humidity move between the sleeper, shikibuton, and base. A firm surface alone is not enough: check for condensation, air both sides, wash removable sheets separately, and never machine-wash or soak the complete shikibuton.
Inside a shikibuton
What a Japanese shikibuton is made of.
A shikibuton is quilted in layers rather than built on springs. HIMARI is approx. 10 cm thick: wool-blend filling, 25% wool, quilted above and below an approx. 8 cm firm polyester support core developed in our own workshop. SORA is approx. 12 cm thick, with a 50% premium wool blend for a fuller, balanced feel. Both have a 100% cotton outer fabric and fold into thirds for airing and storage.
HIMARI combines a firm polyester support core with quilted wool-blend layers for surface cushioning. SORA offers fuller cushioning with a balanced medium feel. Check the construction of each model when comparing it with a topper or another floor mattress.
Sizes and weights
Japanese sizes, measured in centimetres.
Japanese size names do not guarantee a matching local length and width, so compare the centimetre dimensions with the floor space, platform or frame you have. These are the sizes we deliver to your country, with the weight and the folded size of each one.

Made in Japan, and verifiable
Who makes it, and how you can check.
OFUTON KOBO Co., Ltd. sews, inspects and finishes every shikibuton in its own workshop in Oyama, Tochigi, Japan. The family business began in 1873 as a cotton shop in Tokyo and is led today by Nakajō Yūsuke, the fifth generation. The manufacturer is a J∞QUALITY member company, futon manufacturer certification No. K2600190003, and a member of the Japan Futon Manufacturers' Co-operative.
This matters because “Japanese-style” bedding sold abroad is often made elsewhere to a different specification. Ours is made in Japan and shipped from Japan, and the people who make it are named on this site.
Is a shikibuton the same as a Western futon sofa?
No. A Japanese shikibuton is a foldable sleeping layer laid on a firm surface. It is bedding, not a convertible sofa frame.
Can I use a shikibuton every night?
Yes, when the model suits the sleeper and it is used on a clean, firm, level, and breathable surface. Regular airing and moisture checks are part of nightly floor-bedding care.
Can I use it directly on the floor?
A hard floor can work, but it does not breathe like tatami. Use a suitable moisture-control layer, lift the shikibuton after sleep, and check both the underside and floor regularly.
Are the sizes the same as Single or Double?
No. OFUTON KOBO uses Japanese centimetre dimensions. Inch values are approximate references, so measure the intended floor, platform, or frame before ordering.
