Firm support

Portugal guide · Japanese floor bedding
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 English for Portugal, “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 Portugal mattress labels.

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.
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 place it directly on a Portugal 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 90 × 190 cm or 140 × 190 cm?
No. OFUTON KOBO uses Japanese centimetre dimensions. Inch values are approximate references, so measure the intended floor, platform, or frame before ordering.
