Forensic transparency down to thread and glue, every Covelle material disclosed, certified, and traceable. We don't sell the cover. We disclose the core stack: frame, barrier, support, comfort, upholstery. Every material documented. Every active certification verifiable through its issuing body.

What touches your skin is tested against 350+ harmful substances.
The fabric your family touches every day. Certified against 350+ regulated substances at the supplier's OEKO-TEX Standard 100 article level, including phthalates, heavy metals, formaldehyde, and pesticide residues. No PFAS. No antimicrobial treatments. No synthetic stain coatings.
Our upholstery is sourced from Dorell Fabrics, a supplier that holds OEKO-TEX Standard 100 across its product line. The standard tests the finished fabric, not just raw materials: every dye, finish, and treatment in the final fabric has been verified for safety at the strictest consumer threshold available for textiles.
Conventional upholstery fabrics are often treated with PFAS (per- and polyfluoroalkyl substances) for stain resistance, antimicrobial chemical finishes, and synthetic dyes with undisclosed chemical profiles. None of those exist in our fabric.
Your skin is your largest organ. Children absorb chemicals through skin contact at a higher rate than adults. The fabric that touches your family has been cleared under OEKO-TEX Standard 100 at the supplier's article level.
OEKO-TEX Standard 100 is administered by the International Association for Research and Testing in the Field of Textile Ecology. Testing covers over 350 substances regulated for consumer products, including allergenic dyes, chlorinated phenols, organotin compounds, and heavy metals.

Inherent flame resistance without chemical treatments. Naturally breathable.
Joma Wool that meets TB117-2013 fire safety through wool and construction alone, without a single chemical flame retardant. Wool's keratin protein structure chars rather than melts, self-extinguishes, and produces no toxic fumes.
California's original TB117 open-flame furniture-flammability test effectively required added chemical flame retardants to pass. The 2013 revision (TB117-2013) replaced it with a smolder (cigarette-ignition) resistance test that can be met WITHOUT added flame retardants, paired with mandatory flame-retardant disclosure labeling (California SB 1019). Barrier-material and construction routes, like Covelle's Joma Wool batting + construction approach, meet TB117-2013 without chemical additives.
Wool does the same job through molecular structure, not chemistry. It breathes, regulates temperature, and does the job that toxic coatings pretend to do.

Replaces petroleum-based polyurethane foam entirely.
4-inch natural latex core, tapped from Hevea rubber trees in Sri Lanka. This is what replaces the petroleum-based polyurethane foam found in virtually every sofa under $10,000, and most above it.
Polyurethane foam, the comfort material in nearly every conventional sofa, is a petroleum derivative that off-gasses volatile organic compounds including toluene, benzene, and formaldehyde for months to years. It is also the primary carrier for chemical flame retardants. Organic latex replaces all of it.
Latex is naturally antimicrobial, naturally dust-mite resistant, and naturally hypoallergenic, without chemical additives. It is also dramatically more durable: where polyurethane foam compresses and degrades within 3 to 5 years, organic latex maintains its resilience for 15 to 20 years. The sofa will not sag. The cushions will not flatten. The material will not decompose into the compounds it was made from.

100% bio-based. No petroleum. Not a polyurethane.
The layer most brands pretend does not exist. Verid Bio-Core is a 100% bio-based support foam: plant-derived polyols, no petroleum, not a polyurethane. We disclose it because disclosure is the point.
We are transparent about what this layer is and what it is not. It is not a natural material. No structural support foam is, regardless of what any brand claims. What it is: a support foam made from plant-derived polyols, with no petroleum, that is not a polyurethane.

Kiln-dried. Mortise-and-tenon joinery. No formaldehyde adhesives.
FSC-certified kiln-dried hardwood, joined with mortise-and-tenon joinery. No particle board, no plywood, no MDF, no formaldehyde-based adhesives. The skeleton you never see is built to outlast the sofa itself. Lifetime warranty.
Most furniture frames, including many in the $3,000 to $8,000 range, use engineered wood products bonded with urea-formaldehyde or phenol-formaldehyde adhesives. These adhesives off-gas formaldehyde (a Group 1 carcinogen) for years. They are also the reason expensive furniture falls apart: engineered wood loses structural integrity when adhesives degrade.
Kiln-dried hardwood with mortise-and-tenon joinery does not rely on adhesives for structural integrity. The joint itself carries the load. That is why we offer a lifetime frame warranty.
FSC Chain-of-Custody tracks our wood from responsibly managed forests through every stage of processing to the finished frame: sustainable forestry practices, chain-of-custody integrity, and legal compliance at every transfer point.

The invisible layer that matters most.
Adhesives and finishes are the hidden source of VOCs in furniture. These volatile compounds degrade indoor air quality for years. Every adhesive and finish in a Covelle is water-based. No solvents, no lacquers, no added formaldehyde. What you cannot see is just as important as what you can.
Every material documented. Every active certification verifiable through its issuing body.
Hardwood frames are built with lumber from FSC-certified suppliers. Chain-of-Custody certifications are held at the supplier level by Martco / RoyOMartin (FSC-C022036, Louisiana) and Boss Wood Products (FSC-C190932, Brazil). Both are verifiable in the FSC public database.
