Mycelium (Mushroom Composite)
Grown, not mined — furniture from mushroom roots
5 IMAGES — CLICK TO EXPAND
Mycelium is a composite grown from fungal root networks (mushroom mycelium) on organic substrate (sawdust, straw, hemp shiv). Process: substrate + spores → 5–14 days growth → heat treatment (fixing) → finished material. 100% biodegradable: after disposal → compost in 30 days. For furniture: panels, acoustic tiles, decor, packaging, art objects, prototypes.
TECHNICAL PASSPORT
Reception Space experiments with mycelium on 0.5% of projects: acoustic panels (porous structure = sound absorption), decorative inserts (organic texture), art installations (wow-factor: 'furniture from mushrooms'). Leaders: Ecovative (MycoComposite, Mylo), Grown.bio (Netherlands), MOGU (Italy). 2026 trend: mycelium leather (Mylo — Bolt Threads: leather replacement for luxury brands).

Expert Reviews
Average Rating · 5 expert reviews
«Mycelium: my primary material for 4 years. Lamps, vases, panels: 100+ objects. Growth: 7 days (Ganoderma on hemp shiv). Molds: 3D-printed (PLA). Heat treatment: oven 176°F, 24 hrs. Result: lightweight, warm, organic texture. Issue: sterility (1 in 5 molds — contamination). For art market: 10× vs MDF — but story sells.»
«MOGU Foresta: 15 offices in 3 years. NRC 0.75: excellent absorption. Design: textured, ribbed — not boring foam. Install: adhesive to wall (lightweight). ESG: clients write in sustainability report. Price: 3× vs standard acoustics. But: wow + eco = sells. Recommendation: for co-working and tech companies.»
«Mycelium packaging: testing 5 years (replacing EPS for KALLAX). Result: protection = EPS. Decomposition: 30 days (vs 500 years). Issue: scale (production: 10,000 units/month vs 1,000,000 for EPS). Price: 3×. By 2028: scaling (Ecovative partnership). For: luxury lines (current): eco-message.»
«Mylo (Bolt Threads): using for armchair upholstery (luxury: 2 projects). Tactile: like nubuck (soft, velvety). Color: natural beige → dyed (black, brown). Durability: sufficient for upholstery (test: 50,000 Martindale cycles). Price: $300/sq ft (vs natural leather: $60/sq ft). But: vegan + story = luxury clients pay.»
«Mycelium for prototyping: 7 days = 3D object (vs 3D printing: 2 days, but plastic). For: concept models, exhibition mockups. Organic texture: unreplicable by other methods. Minus: accuracy ±3% (living organism). For final product: needs finishing (sanding, coating). For 'first reveal': perfect.»
Frequently Asked Questions
Mycelium is the root system of fungi (underground part). Mushroom (cap) is the fruiting body. For material: mycelium is used (not caps). It grows as 'white web,' penetrating substrate and binding it together. Result: lightweight, porous, strong (for its weight) material. 100% organic.
Safe — after growth: heat treatment (176–212°F, 24 hrs) → mycelium dies. Further growth: impossible. Material becomes inert (like dried wood). Allergens: none (after heat treatment). Certifications: ISO 14001, USDA BioPreferred.
No — mycelium is weak (29–72 PSI: like styrofoam). Countertops need 4,350+ PSI (quartz, wood). Mycelium: for non-load-bearing elements (panels, decor, acoustics, inserts). For structural: combination (mycelium + wood/metal frame). Future: pressed mycelium (2028+).
Density: comparable (4–7.5 lb/ft³). Insulation: comparable. Sound absorption: mycelium better (NRC 0.65 vs 0.25). Ecology: mycelium — compost in 30 days (styrofoam: 500 years). Price: mycelium 3–5× more expensive. Fire: mycelium better (self-extinguishing vs flammable). For packaging: mycelium wins (IKEA, Dell, Puma).
No — mycelium leather: grown mycelium → processed (tanning, dyeing). Tactile: like suede/nubuck. Strength: comparable to natural (tensile). Brands: Mylo (Bolt Threads — for Adidas, Stella McCartney), Reishi (MycoWorks — for Hermès). Price: from $300/sq ft (luxury positioning). Vegan: 100%.
Yes — MOGU (Italy): acoustic panels from mycelium. Foresta series: textured (designer). Colors: natural (beige, grey, brown). NRC: 0.75 (office standard: 0.70). For: open-space, co-working, meeting rooms. Price: from $30/panel (24×24"). Eco-statement for ESG reporting.
Yes — DIY kits: Grown.bio, Ecovative. Process: substrate + spores → mold → 7–14 days (77–86°F, 80% humidity) → heat treatment (oven 176°F, 24 hrs). Mold: 3D-printed or cardboard. Result: decor, lamp, vase. Difficulty: medium (needs sterility — otherwise contamination). For: education, prototyping, hobby.
2026: niche (acoustics, packaging, luxury leather). 2028: mass packaging (IKEA, Amazon). 2030: structural mycelium (pressed, 1,450+ PSI). 2035: mycelium building material (insulation, panels). Investment: $500M+ (Bolt Threads, Ecovative, MycoWorks). Trend: bio-manufacturing = 'factory is a bioreactor.'
