After sleep, lift or stand the shikibuton so you can inspect its underside and the supporting surface. Let both release moisture. Air both faces in a ventilated place, turn the bedding over and rotate it head to foot regularly. Fold and store it only when it is dry.
Details to check before choosing
Do not machine-wash or soak the whole HIMARI or SORA. Follow the model’s spot-cleaning instructions for a small surface stain and dry the affected area completely. Wash the removable sheet or cover according to its own care label; those instructions are different from washing the filled shikibuton.
