So for eco-friendly interior design dealing with any wood goods, what I want you to do, after you determine your budget and style of the item, is to look for eco-friendly pieces that are better for your health and the environment by avoiding MDF composite pieces and choose solid wood pieces. Compressed wood furniture often has formaldehyde in the wood adhesive.
Now any wood won't do. We can't just chop down jungle and habitat to get that beautiful desk or cabinet. Look for suppliers that have FSC (forestry stewardship council) certified wood, which means it was responsibly sourced. With this in mind you can curate a healthier collection for you and the planet.
