What’s inside

Nature, layered.

A soft, breathable organic cotton cover sits gentle against the skin. Beneath it, natural Thai latex answers every movement with responsive support, while organic wool regulates temperature the way only wool can — warmer in winter, cooler in summer.

Graphene memory foam spreads warmth evenly across the surface instead of letting it pool, and the house signature — the Sleepm BioCrystal layer, sixteen crystals balanced with gold and silver — rests at the heart of it, the same blend the family sleeps on.

Finished with elegant embroidery and hand-tufted detailing, built from eco-conscious materials, and made to be slept on for years — not seasons.
