Choose HIMARI or SORA when the published dimensions fit your room and you can regularly lift, air and keep the bedding dry. Compare the firmer HIMARI with the fuller SORA by personal preference, storage space and the actual local offering. Thickness alone does not determine comfort.
Details to check before choosing
Measure the usable length and width of the floor, platform or bed base, including any raised edges. Compare those measurements with the exact model and size offered for your country. Then check the folded size and weight, and choose a sheet or cover that fits the same dimensions.
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.

Measure the cupboard as well as the sleeping space
For an Andorran apartment where bedding shares storage with everyday belongings, the cupboard can be the deciding measurement. A folded shikibuton still needs a clear opening, enough shelf space and a manageable route from the floor. Check these before choosing a model. You will also need somewhere to leave both faces exposed to air before closing the bedding away; a tightly packed cupboard cannot do that job.
HIMARI measures 210 cm in length and SORA 200 cm. Compare the usable platform, including any enclosing edges, with the actual model dimensions. HIMARI's steadier medium-firm feel may appeal to one person, while another may prefer SORA's fuller cushioning. Neither description predicts everybody's comfort. Both fold into thirds, so compare the folded dimensions and weight with your intended storage. If your morning routine leaves little room for airing, resolve that practical constraint before ordering.
