Materials: What to Lookout For
With almost every brand nowadays touting sustainable credentials, it’s hard to know what’s an ethical practice and what’s greenwashing. Here’s the breakdown.

Avoid Harmful & Fossil Fuel Sofa Materials
If you didn’t know already, plastic and polyester are fossil fuel materials. It’s best to avoid Chrome-tanned leather too. The process creates toxic wastewater that has a detrimental impact, especially in developing countries. Vegetable-tanned leather is a better alternative.
Spot Certifications
We’re often told to opt for ‘natural’ materials – but what does actually mean? It’s always best to swerve past the fuzzy unsubstantiated buzzwords and rely on brands that can back up their claims with quantifiable evidence. Of course, linen, cotton, and hemp materials are good. But you can take it a step further and look for cotton that has a GOTS certification. What’s that? It’s the Global Organic Textile Standard that ensures the organic status of the textile and responsible manufacturing across the supply chain.

Look For Low VOC levels
First off, what actually is a VOC level? It stands for a volatile organic compound, and its often used in the manufacturing process for safety concerns like flammability. Interior designer, Nicola Holden for Refinery29 explains that ‘a ‘cheap’ sofa is usually filled with foam and many of these upholstery foams have been made from polyurethane. Polyurethane is flammable, so it’s also treated with flame retardants that often contain hazardous chemicals.’ So as we’re seeing interiors becoming as bad as ‘fast fashion’, these cheaper materials (cheap foam over organic filling; composite wood over solid wood), means they are more likely to be made of – and treated with – VOCs.
Look for Responsibly Sourced Wood
Responsibly sourced wood, that’s been safely treated, is your go-to. An FSC Certification is a widely recognised certification for responsibly managed wood that’s good to look out for.
