The original vegetable cashmere.

Soybean fiber is the world's first plant-based protein textile — born from the same soybeans that feed the planet. Softer than cashmere, as lustrous as silk, and built from food industry byproduct that would otherwise go to waste.

Soybean fiber science
Plant-Based
Protein
Not Synthetic
The Science

From tofu factory to your bedroom — the real story.

Soybean fiber begins as a byproduct of tofu and soy milk production. The protein-rich pulp left behind after food processing — which would otherwise be discarded — is collected, refined, and bio-spun into one of the world's finest natural fibers. No new land. No dedicated water. Just brilliant use of what already exists.

1
Soy Protein ExtractionDefatted soybean meal from tofu production is processed to isolate globulin — the plant protein that gives soy fiber its skin-friendly properties.
2
Wet SpinningThe protein is dissolved and extruded through precision nozzles to form ultra-fine filaments with a natural silk-like luster and exceptional tensile strength.
3
Bio-Active FiberThe finished fiber carries multiple amino acids, natural antibacterial properties, and a moisture-wicking structure that outperforms conventional cotton and polyester.
Why It Performs

What makes soybean fiber genuinely different

Known as “vegetable cashmere” in the textile world, soybean fiber earns that title through measurable performance — not marketing language.

🥬

Softer Than Cashmere

Soybean fiber filaments are exceptionally fine, producing a fabric that feels smoother than cashmere and sits against skin like a second layer — without any pilling or static.

Cashmere-Level Softness
🌞

Natural Thermal Balance

The unique micro-porous structure creates air pockets that insulate in winter and breathe in summer — making every product in this collection genuinely all-season.

All-Season Comfort
💧

Superior Moisture Wicking

Soybean fiber absorbs moisture as efficiently as cotton but ventilates far better — keeping your skin dry and the surface fresh throughout the night.

Anti Night Sweat
🌿

Natural Antibacterial

Soy protein naturally inhibits bacterial and mite growth — the same amino acid structure that nourishes your skin also actively resists the microbes that cause odor and irritation.

Anti-Mite Shield
☀️

UV Protective

Soybean protein fiber offers greater UV resistance than most natural fibers including cotton — an underrated benefit that makes it especially valuable for daytime throws and loungewear use.

Every product in this collection is made from a byproduct of the food industry. No dedicated land, no extra water, no additional agricultural footprint — just circular production done right.

What Customers Say

You notice it from the very first night.

★★★★★

I wake up cooler and less itchy

I have eczema and most bedding makes it worse by morning. Since switching to the soybean fiber blanket I have noticeably fewer flare-ups. The fabric is genuinely different — softer and cooler than anything I have tried before.

The mattress topper changed everything

I bought the 10cm mattress topper expecting it to feel like a regular pad. It does not. It is remarkably soft but still supportive. The elastic bands hold it in place perfectly and it has not shifted once in three months.

Got it for my baby — it is exactly right

The Class A certification was the main reason I chose this. My daughter has sensitive skin and she has slept better since we switched her quilt. I love that it is a plant-based material and not just another synthetic blanket.

Common Questions

Everything you want to know before buying

Soybean fiber is still new to most shoppers. These are the questions we hear most often.

What exactly is soybean fiber and how is it made?
Soybean fiber is a plant-based protein textile derived from the byproduct of tofu and soy milk production. The protein-rich pulp left after food processing is refined and wet-spun into ultra-fine filaments. The result is a fiber that is naturally soft, breathable, and antibacterial — with no synthetic origin and no dedicated agricultural footprint.
What does Class A safety certification mean?
Class A is the highest textile safety standard, originally established for products intended for infants and mothers. It means the fabric has been tested for harmful substances, formaldehyde levels, pH balance, and colorfastness — and meets the strictest thresholds. All products in this collection carry Class A certification, making them safe for even the most sensitive skin.
Is soybean fiber suitable for people with allergies or sensitive skin?
Yes. Soybean fiber is naturally hypoallergenic, pH-neutral, and resistant to dust mites and bacteria. Its smooth filament structure also reduces friction against sensitive skin. The Class A certification further confirms it is free from irritating chemicals. For people prone to eczema or skin reactions from synthetic bedding, soybean fiber is one of the best alternatives available.
How do I care for soybean fiber products?
Most products can be machine washed on a gentle cycle at 30°C with mild detergent. Avoid bleach and high-temperature washing as these can degrade the protein fiber over time. Air dry or tumble dry on low heat. Soybean fiber has natural anti-crease properties so heavy ironing is rarely needed.
Why do some products have 100% soy filling and others have 20%?
The filling ratio depends on the product type. The mattress topper uses 100% soybean fiber fill for maximum performance. The blankets and pillows use a 20% soy / 80% supportive fiber blend — which is the optimum ratio for loft, durability, and antibacterial performance in those specific product formats. Both ratios carry the same Class A certification.
