    The mycelium acts like an organic glue, binding the chair together and transforming the flimsy husk into a sturdy household item. Tiny perforations in the surface gave way and allowed mushrooms to sprout, creating an unplanned organic upholstery. *Photo: Studio Eric Klarenbeek*

    "We can 3-D print both the house, insulating structure and its skin at once," he says. "By combining 3-D printing and mycelium, the applications are endless." *Photo: Studio Eric Klarenbeek*

    Klarenbeek believes getting more designers involved in probiotic production is critical and is trying to productize his mobile lab with hopes that other designers will take up the challenge. *Photo: Studio Eric Klarenbeek*

    Klarenbeek attempted to print the chair's form in a traditional manner using a straw-based polymer with the hopes that mushrooms would grow on the surface. Sadly, it didn't work out as expected. *Photo: Studio Eric Klarenbeek*
