The 4-Pack Polycarbonate Outdoor Chairs Piaris made of polycarbonate with a translucent finish are perfect for a variety of outdoor settings, such as terraces, gardens, patios and balconies. Its lightweight and durable design makes it ideal for poolside lounge areas, outdoor café spaces or seating areas at outdoor events. It is also a stackable chair and its easy-to-clean material makes it a practical option for high-turnover locations, such as restaurants and bars. To extend its lifespan, we recommend avoiding continuous exposure to sunlight, rain, and humidity by protecting it when not in use, either in indoor areas or by covering it. When cleaning, use a cloth, avoiding the use of chemical products. Polycarbonate is worked with a mold, it may show mold marks but this does not affect its quality.
