Park chairs are exposed to harsh outdoor conditions, including sunlight, rain, and temperature fluctuations, which can cause finish deterioration over time. To combat this, manufacturers use weather-resistant coatings such as polyurethane or powder coatings that provide a protective barrier against UV rays and moisture. Additionally, high-quality materials like aluminum, teak, or powder-coated steel are chosen for their durability and resistance to rust and fading.

Regular maintenance, such as cleaning with mild soap and water, also helps preserve the finish by removing dirt and debris that can accelerate wear. Some park chairs feature designs with drainage holes to prevent water accumulation, reducing the risk of wood rot or metal corrosion. By combining durable materials, protective coatings, and proper care, park chairs maintain their appearance and functionality for years, even in demanding outdoor environments.
