Natural Materials

The materials in a Japanese bedroom aren’t decorative choices — they’re functional ones. Tatami is made from rice straw and rush grass because those materials regulate humidity and support the body. Futon cotton compresses and breathes in ways that synthetic alternatives don’t. This section covers the natural materials at the core of Japanese sleeping design: what they are, how they’re made, how to care for them, and why natural materials in bedroom design make a measurable difference to how a space feels and how well you sleep in it.
