Technology
Biotechnology, guided by design.
A pure mycelium mat grown through biotechnology and design — engineered for structural independence, process stability and eco-integrity.
Structure
The mat is the material.
Most leather alternatives laminate a coating onto a textile or polymer backing. Mycerra™ uses no non-woven backings, scaffolds or foreign substrates: it is a self-supporting mat cultivated entirely from mycelium. That is what lets it be shaved, dyed and embossed like a hide — and composted at the end of its life.
Cultivate
Mycelium is grown into a continuous, self-supporting mat in controlled facilities in Korea — no backing fabric, no scaffold, no foreign substrate in the final material.
Stabilize
Where hides are tanned, Mycerra™ is stabilized. A proprietary process turns the cultivated mat into a durable material, defining its strength, flexibility and handfeel.
Finish
Like premium hides, Mycerra™ takes aniline dyeing, embossing and protective finishing — from a raw natural surface to deep, three-times-dyed colour.
Performance
Redefining how performance materials are made.
Pure mycelium structure
No textile or polymeric backing — a self-supporting mat cultivated entirely from mycelium.
Leather-grade performance
Naturally strong, flexible, and shavable — comparable to premium hides.
Process stability
Uniform growth under ambient conditions ensures scalability and industrial consistency.
Finishing versatility
Supports aniline-style, embossed, or undyed natural surface options.
