FAQ. Materials, Certifications & Sustainability | Covelle

No. CertiPUR-US certifies that polyurethane foam meets safety standards for content and emissions. It does not require or verify organic materials. All CertiPUR-US certified foam is polyurethane (petroleum-derived). For organic certification, look for GOLS (latex) or GOTS (textiles).

Yes. We provide SDS documents for every material layer, the same documentation required in commercial and medical environments. Request them via the certification package download or email support@covelleliving.com.

Yes. Every certification is renewed on its standard cycle and verified annually. We can provide current certificates with license numbers and expiration dates on request.

A Declare label is the building-materials equivalent of a nutrition label. It discloses intentionally added ingredients and residuals at or above 100 ppm (parts per million), reported by chemical name and CAS number. Each ingredient is then screened against the Living Building Challenge Red List — a registry of the worst-in-class materials and chemicals. A product rated 'Red List Free' contains none of these restricted substances. Covelle's Tribeca leather carries Declare Certified status with Red List Free designation. This means every chemical in the leather — down to 100 ppm — is disclosed and verified safe.

Because each certification has a specific, limited scope. CertiPUR-US covers foam. OEKO-TEX covers textiles. GOLS covers latex. GREENGUARD Gold covers room-level emissions. Declare covers material composition. No single certification tests everything. A comprehensive certification stack covers every material and every exposure pathway.

GREENGUARD Gold, because it tests the assembled product at room level, catching interactions between materials that component-level testing misses. But it should be supported by material-specific certifications like GOLS, GOTS, and OEKO-TEX.

They take different approaches to the same goal: verified material safety. OEKO-TEX® Standard 100 Tests finished textiles against a catalog of 350+ harmful substances — including heavy metals, pesticides, phthalates, and restricted chemicals. If the substance is found above the limit, the product fails. This is the certification carried by Washed California fabric. Declare Provides full ingredient disclosure at 100 ppm, then screens against the Living Building Challenge Red List. Rather than testing for specific bad actors, Declare names everything that's in the product and lets you verify it. This is the certification carried by Tribeca leather. Both certifications require third-party verification and are renewed periodically. Different methods, same commitment to transparency.

No. We do not treat our fabrics with PFAS, PFOA, PFOS, or any per- or polyfluoroalkyl substances. Our OEKO-TEX Standard 100 and Declare Red List Free certifications independently verify this.

Yes. Most certifications require annual renewal with updated testing. Always ask a brand if their certifications are current and request the certificate with its expiration date.

Structural support requires properties that natural latex alone does not provide, specifically the high-resilience density needed to support a frame and maintain sofa geometry for 15+ years. Verid Bio-Core achieves this with 61% plant-derived content and CertiPUR-US certification. We disclose it because most brands do not, and transparency about trade-offs builds more trust than pretending they do not exist.

We welcome scrutiny. Many customers with chemical sensitivities have verified our products with personal VOC meters. We provide complete SDS documentation and GREENGUARD Gold emissions data for review by your environmental medicine provider. Contact support@covelleliving.com for a materials package tailored to medical documentation requirements.

GREENGUARD Gold tests emissions, not material composition. A sofa can pass GREENGUARD Gold while using conventional polyurethane foam and chemical flame retardants, as long as total emissions stay below threshold. GOLS and GOTS require organic materials, which most mass-market products do not use.

We encourage comparison. See our certifications, ask other brands for theirs, and compare documentation, not marketing claims. We hold six independent certifications from six different organizations. Most competitors hold one or two.

GREENGUARD Gold tests the assembled product in a sealed chamber, measuring total VOC emissions at room level over a defined period. It is the most stringent indoor air quality certification available for furniture, originally developed for environments like hospitals and schools where air quality is medically critical.

It depends on what is inside it. If your sofa contains polyurethane foam with chemical flame retardants (most do), it is releasing VOCs and flame retardant compounds into your indoor air. These chemicals migrate into household dust and are ingested through hand-to-mouth contact, especially by children. If you are concerned, an indoor VOC monitor can measure your current exposure.

Ask for documentation. Genuine certifications have license numbers that can be verified on the certifying organization's website. If a brand says "non-toxic" but cannot provide a specific certification with a verifiable number, the claim is marketing. If they say "natural materials" but will not disclose every material in the product, they are selectively transparent, which is the same as opaque.

Because there is no legal requirement to do so, and because disclosure would reveal the gap between marketing claims and material reality. A brand that markets "luxury craftsmanship" while using particle board frames and polyurethane foam benefits from your not knowing. Disclosure is voluntary in this industry. The brands that do it are the brands with nothing to hide.

It is off-gassing: the release of volatile organic compounds from foam, adhesives, fabric treatments, and engineered wood products. The smell is strongest in the first days and weeks, but many compounds continue to off-gas at lower levels for months to years. It is not a sign of quality. It is a chemical event.

Not necessarily. Price reflects design, brand, retail markup, and materials cost, but not always materials safety. A $7,000 sofa may use the same polyurethane foam and chemical flame retardants as a $700 big-box sofa. Price is not a proxy for purity. Certifications are.

GOLS-certified organic latex is the safest comfort material. For the frame, FSC-certified solid hardwood joined without formaldehyde adhesives. For fabric, OEKO-TEX Standard 100 or GOTS-certified organic textiles. The safest overall sofa combines all of these with GREENGUARD Gold certification verifying room-level emissions.

CertiPUR-US is a meaningful baseline but only covers the foam. It does not test fabric, frame, adhesives, or the assembled product. For comprehensive safety, look for CertiPUR-US plus GREENGUARD Gold plus material-specific certifications like GOLS, GOTS, or OEKO-TEX.

Genuinely certified non-toxic sofas with organic materials, solid hardwood frames, and comprehensive testing typically start around $2,500 and range to $6,000+ depending on size and configuration. Products below $2,000 claiming "non-toxic" usually hold only baseline certifications. The certification stack is a better indicator of value than the price tag.

"Organic" refers to how materials are grown and processed (supply chain standard). "Non-toxic" refers to what the finished product emits and contains (safety standard). A product can be organic but still emit VOCs from adhesives. A product can be non-toxic (low emissions) but use non-organic materials. The most protective products are both: organic materials AND verified non-toxic emissions.

Peak off-gassing occurs in the first 24 to 72 hours. Noticeable smell fades within 2 to 4 weeks. Measurable VOC emissions from polyurethane foam continue for 6 months to 2 years. Formaldehyde from engineered wood can emit for 3 to 8 years. Flame retardant migration into household dust is continuous.

You can smell some VOCs, but many are odorless. Flame retardant compounds migrate through dust, not air. The absence of smell does not mean the absence of chemical exposure.

The smell is a mixture of VOCs from foam, adhesives, and fabric treatments. Prolonged daily exposure can contribute to respiratory irritation, headaches, and hormonal disruption, particularly in children and people with chemical sensitivities.

Covelle sofas eliminate the source materials that cause off-gassing: organic latex instead of polyurethane foam, wool instead of chemical flame retardants, solid hardwood instead of engineered wood with formaldehyde adhesives. GREENGUARD Gold certification verifies the assembled product meets the strictest indoor air quality standard available.

Babies are the most vulnerable population. They breathe more air per body weight, spend more time at floor level where VOCs settle, have higher hand-to-mouth contact with contaminated dust, and have developing organ systems more susceptible to chemical exposure. Nursery furniture should be certified low-emission and ventilated for 60+ days before a baby is present.

Covelle does not accept self-reported sustainability claims. Every material in the product must carry independent, third-party certification with verifiable documentation. For fabrics: OEKO-TEX Standard 100 with a valid certificate for the specific SKU. For leathers: Declare label with Red List screening for the specific SKU. For all components: an evidence pack including ingredient disclosure, SDS, VOC emissions test, certification copies, and chain of custody documentation. This is Covelle's baseline — not a premium tier. Every sofa ships with this standard.
