Our Materials

A Natural Beginning

Silk is a natural protein fiber created by silkworms as they form their cocoons.

Mulberry silk comes from the domesticated silkworm, traditionally nourished on mulberry leaves. From leaf to cocoon, the material begins through a process rooted in nature.

Naturally Smooth, Quietly Refined

  • Fine Natural Fibers

    Fine silk filaments help create a smooth and even surface.

  • Soft, Fluid Drape

    Mulberry silk settles into light, natural folds.

  • Subtle Natural Sheen

    Silk reflects light softly rather than producing a harsh synthetic shine.

Rooted in Nature

  • Mulberry Leaves

    Mulberry leaves provide the traditional food source for the silkworms that produce mulberry silk.

  • Silkworm Cocoons

    Silkworms form cocoons from fine, continuous silk filaments created naturally by their bodies.

  • Silk Filaments

    These fine filaments become the foundation of the smooth, flowing fabric known as mulberry silk.

  • Silk Fabric

    Finally, through processes such as reeling and weaving, it becomes silk.

Mulberry Silk at the Heart of RoraSilk

We select it because its natural origin, smooth feel, and softly flowing character reflect the kind of sleep essentials we want to create—simple, gentle, and considered.
The silk fabric used across our collection is made from 100% mulberry silk.

Nature, Woven into Silk

From mulberry leaves to silkworm cocoons, our material story begins with nature and continues in every soft fold of mulberry silk.
