FYI ➜ “Non-toxic” doesn’t have a definition, and I use the words chemical-free, toxin, and toxic on Interior Medicine inaccurately. I do this for practical purposes, for now: they’re accessible terms that allow people to find what they’re looking for, and they’re shorthand for a complicated problem. I made an entire (free!) course about this. Check it out here.

More About Mycelium Furniture

What is mycelium?

Mycelium is essentially the roots of mushrooms, or more accurately, a “network of hyphae.” They live in soil and on other organic things like logs, and are beneficial to plants around them. They are safe, and are used in bioremediation and composting. Now, mycelium is also being used to make furniture, and even foam alternatives.

Why is mushroom furniture popular?

Furniture made with mushroom roots is becoming more popular because it is carbon-negative, very strong, insulating,  and can be used as an alternative to foam and plastic. It’s a type of biophilic design.

What is Biophilic Design?

In short, it connects the people inside a building to nature— in all its forms. That means using rocks, metals, geometry, warm light, vistas, refuges, and views, in addition to greenery. It also includes fresh air, pure water, and natural noise. It includes physical, sensory, metaphorical, morphological, material, and spiritual aspects of nature.
