Outdoor seating in urban areas, such as park benches and café tables, may seem inconsequential to most, but for microscopic organisms like water bears (tardigrades), these structures can create unique microhabitats. Tardigrades, known for their extreme resilience, often inhabit moss, lichen, and damp surfaces—conditions replicated in the crevices and shaded areas of outdoor furniture.

Urban outdoor seating provides moisture retention and shelter from direct sunlight, mimicking natural environments where tardigrades thrive. The accumulation of organic debris, such as fallen leaves or spilled beverages, further enriches these microhabitats, offering food sources and breeding grounds. Studies suggest that water bears in cities may adapt to these artificial niches, demonstrating their remarkable ability to colonize human-altered landscapes.

However, frequent cleaning or use of chemical treatments on seating can disrupt these microhabitats, posing challenges for tardigrade populations. By understanding these interactions, researchers gain insights into urban biodiversity and the unintended ecological roles of everyday structures.
