For urban balconies, patios, and rooftops, woven PE (polyethylene) rattan has become a dominant material for outdoor furniture. The central question for buyers is its long-term durability, specifically regarding sagging. The answer is that high-quality PE rattan is exceptionally durable and resistant to sagging when properly constructed.
Premium PE rattan is UV-stabilized, waterproof, and designed to withstand temperature fluctuations from harsh sun to winter cold without cracking or fading. Unlike natural rattan, it won't dry out, rot, or become brittle. Regarding sagging, the material itself has inherent elasticity and memory. The key factor is the core frame. Furniture with a sturdy, powder-coated aluminum frame provides critical support, preventing the woven strands from bearing excessive structural weight and thus minimizing sag risk.
However, not all PE rattan is equal. Low-density weaves on weak frames may stretch or deform over years of heavy use. To ensure longevity, look for high-density, thick weaves and robust frames. With proper care—simple cleaning and occasional covering during extreme weather—a quality PE rattan set should maintain its shape and integrity for a decade or more, making it a durable and sag-resistant choice for the urban outdoor environment.
