Understanding VOCs and Why Natural Materials Matter Indoors
That new furniture smell has a name: VOCs. Here is what they are, why some materials contribute more than others, and how certifications like GOTS and GOLS offer a documented reference point.
If you have ever unwrapped a new piece of furniture and noticed a strong, distinct smell, you have likely encountered volatile organic compounds, or VOCs. Understanding what they are helps explain why the materials inside a home can matter as much as how a room looks.
VOCs are a broad category of carbon based chemicals that evaporate easily at room temperature. Many are released gradually from certain adhesives, foams, and synthetic finishes as they cure or age, a process sometimes called off gassing. According to publicly available research from environmental health organizations, indoor air can carry meaningfully higher concentrations of some VOCs than outdoor air, in part because so many everyday products contribute small amounts over time.
Materials vary widely in how much they contribute to this. Certain polyurethane foams, particle board, and synthetic adhesives are commonly cited sources, while natural materials processed without those additives, such as natural latex, organic wool, and organic cotton, generally involve fewer added chemical compounds to begin with. That does not mean every natural material is automatically free of any emissions, but it does mean there are typically fewer synthetic inputs in the first place.
This is part of why certifications like GOTS and GOLS matter beyond the word organic itself. These standards restrict certain chemical additives during processing and require independent testing at various stages, giving shoppers a documented reference point rather than relying on a label alone. No certification can promise a completely emission free environment, since ventilation, room size, and a household's full mix of furnishings all play a role too, but it does offer a transparent, third party verified starting point.
Paying attention to material choices will not solve indoor air quality on its own, but it is one of the more concrete steps within a household's control. Small, informed choices about what comes into a home add up over time.
