When choosing the correct size products from our collection or when requesting a custom size product, there are some important sizing measurements to keep in mind.

The sizes stated for all our products are the measurements of the cut fabric casing before filling.

After the filling the casing with cotton stuffing, the shiki futon's height will increase. The width and length of the Shiki Futon Mattress will approximately decrease by about 5 cm. So if you would like to make a Shiki Futon Mattress that fits perfectly to your bedframe or tatami mat, we recommended adding an approximate additional 5 cm to both its width and length. See picture below for example.

The above pictures show the comparison of the Shiki Futon Mattress before and after stuffing. The size of the fabric casing of the Shiki Futon Mattress (see BEFORE picture) measures 100cm ×210cm. Once filled with cotton stuffing (see AFTER picture), the final Shiki Futon Mattress size will be smaller than 100cm × 210cm due to the increase in height.
