1. When Surface Becomes Art
It is no coincidence that High Level Nubuck is regarded as one of GreenMoss’s most distinctive leather lines.
Unlike conventional aniline or semi-aniline finishes, GM857 features a nubuck crackle effect—a velvety, matte surface interwoven with naturally occurring micro-cracks that resemble the marks of time.
Each hide is a one-of-a-kind piece. No two surfaces are ever identical, as the crackle pattern emerges from the inherent structure of the grain itself.
Under warm lighting (D65 daylight reference), High Level Nubuck subtly transforms—soft yet powerful—evoking the presence of a living sculpture within an interior.
“GM857 is not just a material—it is emotion you can touch.”
2. Technical Integrity — Where Art Meets Standards
High Level Nubuck balances softness, durability, and light stability through carefully controlled finishing:
| Key Parameter | Standard | Performance |
|---|---|---|
| Thickness | ISO 2589 | 1.2 – 1.4 mm |
| Dry Rub Fastness | EN ISO 11640 | 50 cycles ≥ Grade 3 |
| Wet Rub Fastness | EN ISO 11640 | 20 cycles ≥ Grade 3 |
| Tensile Strength | EN ISO 3376 | ≥ 10 N/mm² |
| Tear Strength | EN ISO 3377-1 | ≥ 20 N |
| Flex Resistance | EN ISO 5402 | ≥ 20,000 cycles (no cracking) |
| Light Fastness | EN ISO 105-B02 | ≥ Grade 3 (Blue Scale) |
| pH Value | EN ISO 4045 | 3.2 – 4.0 (Pass) |
| Cigarette & Match Resistance | BS 5852:1979 | Pass |
Notably, the surface is finished in aniline nubuck—with no glossy topcoat—preserving the leather’s natural texture and breathability. This allows better thermal comfort on contact and helps reduce static electricity in interior environments.
3. The “Crackle Grain” Visual Effect — The Language of Time
The soft crackle visible on the surface is not a defect. It is the result of a controlled surface treatment, where tanning engineers deliberately induce micro-fractures within a thin aniline layer.
When light strikes at an angle, these cracks reflect differently, producing a vintage glow reminiscent of patinated walls in classical Italian architecture.
For this reason, GM857 is frequently selected for:
-
Lounges & private villas – conveying warmth and a sense of time
-
Luxury showrooms – creating a strong visual focal point
-
Hotels & hospitality spaces – refined elegance without ostentation
“True beauty lies not in perfection, but in how a material preserves time.”
4. Tactile Emotion — When Leather Is Meant to Be Felt
What truly sets GM857 apart is its tactility.
The nubuck surface is lightly sanded, resulting in a velvety texture that absorbs light and responds gently to body temperature.
The touch is often described as:
-
“Dry to the touch, yet warm and alive”
-
“Soft without being slippery”
-
“A surface with perceptible depth the moment you touch it”
Applied to sofas, lounge chairs, or headboards, GM857 delivers a premium tactile experience and an aesthetic depth that synthetic materials cannot replicate.
5. Applications & Ideal Spaces
GM857 is designed for interiors that value individuality and emotional expression:
| Application | Recommended Spaces | Aesthetic Impact |
|---|---|---|
| Sofa & Armchair | Villas, lounges, boutique hotels | Warm luxury, handcrafted feel |
| Wall Panels | Showrooms, executive offices | Striking texture under angled light |
| Headboards | Penthouses, resorts | Relaxed, organic comfort |
| Art Installations | Galleries, concept stores | Natural depth, one-off character |
Lighting tip: GreenMoss recommends warm lighting at 3000K–3500K to enhance the natural crackle, allowing the surface to visually “move” with light.
6. A Signature Statement — When Material Becomes Brand Language
GM857 is more than a product; it is a declaration of GreenMoss’s material philosophy:
-
Respecting natural character—never concealing imperfections
-
Merging advanced tanning techniques with handcrafted sensibility
-
Subjecting every hide to rigorous inspection before delivery
Through High Level Nubuck, GreenMoss reinforces its role as a Material Solutions Partner—where materials do more than serve design; they help tell the story of contemporary Vietnamese living in an international design language.
