When it comes to park chairs, the most researched aspect is undoubtedly durability and material performance. Researchers and designers consistently focus on how outdoor seating withstands weather, heavy use, and vandalism. Studies often compare materials like treated wood, recycled plastic, and powder-coated metal to determine longevity and maintenance needs.

Another critical area is ergonomics, ensuring comfort for diverse users while maintaining structural integrity. Additionally, sustainability and eco-friendly materials are gaining traction in recent studies, reflecting a shift toward greener urban furniture. Whether for public parks or urban plazas, these findings help shape durable, comfortable, and sustainable seating solutions.
