Guide to Furniture Finish Toxicity: Understanding and Choosing Healthier Options


Choosing furniture for your home involves not only aesthetic considerations but also concerns about the materials and finishes used. Furniture finishes, in particular, can contain various chemicals that may pose health risks. This guide aims to help you navigate the world of furniture finishes, understand potential toxicity issues, and make informed choices for a healthier living environment.

1. Understanding Furniture Finish Toxicity

  • VOCs (Volatile Organic Compounds):
    • Many conventional furniture finishes contain VOCs, which can contribute to indoor air pollution. VOCs can off-gas into the air, leading to respiratory and other health issues.
  • Formaldehyde:
    • Found in some wood finishes and adhesives, formaldehyde emissions can cause respiratory problems and have been classified as a carcinogen.
  • Heavy Metals:
    • Certain finishes may contain heavy metals like lead or mercury, posing serious health risks, especially in households with children or pregnant individuals.

2. Identifying Low(er)-Toxicity Finishes

  • Water-Based Finishes:
    • Opt for water-based finishes, which generally have lower VOC levels compared to solvent-based counterparts.
  • Natural Oils and Waxes:
    • Finishes like linseed oil, tung oil, and beeswax provide a natural and low-toxicity alternative.
  • Low-VOC and VOC-Free Finishes:
    • Look for finishes labeled as low-VOC or VOC-free to minimize the impact on indoor air quality.

3. Certifications and Labels

  • GREENGUARD Certification:
    • Products with GREENGUARD certification meet strict chemical emissions limits, ensuring healthier indoor air quality. 
  • FSC-Certified Wood:
    • Furniture made from wood with Forest Stewardship Council (FSC) certification indicates sustainably sourced and responsibly harvested materials. Wood is inherently a renewable resource, but it’s a good way to ensure you’re not contributing to clear-cutting & deforestation.

4. DIY and Natural Finishing Options

  • Homemade Finishes:
    • Consider DIY options using natural ingredients like beeswax, olive oil, or vinegar for a chemical-free finish.
  • Raw and Unfinished Furniture:
    • Choosing furniture in its raw and unfinished state allows you to control the finishing process with non-toxic materials.

5. Questions to Ask When Purchasing Furniture

  • Ask about Finish Ingredients:
    • Inquire about the specific ingredients used in the furniture finish, and research any unfamiliar substances.
  • Check for Certifications:
    • Look for certifications and labels that indicate a commitment to environmental and health standards.
  • Request Material Safety Data Sheets (MSDS):
    • Manufacturers should provide MSDS, which detail the potential health hazards of the product's components.

6. Proper Ventilation

  • Air Out New Furniture:
    • When you bring new furniture home, allow it to air out in a well-ventilated space to reduce off-gassing.
  • Improve Indoor Ventilation:
    • Ensure good airflow within your home by using exhaust fans and opening windows regularly.

7. Regular Maintenance

  • Inspect and Refinish:
    • Periodically inspect furniture finishes for wear and tear. Refinish with non-toxic options when necessary.

  • Avoid Harsh Cleaning Chemicals:
    • Use natural, non-toxic cleaners to maintain furniture without introducing harmful chemicals.

Prioritizing low-toxicity furniture finishes contributes to a healthier home environment. By understanding the potential hazards and making informed choices, you can enjoy stylish and sustainable furniture without compromising your well-being. Always remember to do thorough research, ask questions, and choose furniture that aligns with your commitment to a healthier lifestyle.
