Durable HIPS Material: Crafted from wood-like HIPS material with anti-corrosion and moisture-proof properties, it offers more stable structure than real wood, effectively resisting outdoor mold and insect damage, with a longer service life than ordinary wooden furniture. Ergonomic Streamlined Backrest: Features a streamlined ergonomic design that perfectly fits the natural curve of the human spine, providing even support from neck to waist for fatigue-free leaning over extended periods. Multi-Functional Wide Armrests: Precisely calculated armrest width offers a comfortable angle for natural arm placement and serves as a stable temporary platform for small items like books and snacks without slipping. Rust-Proof Stainless Steel Hardware: All connections use rust-treated stainless steel hardware, preventing rust and loosening in humid, rainy outdoor environments for enhanced structural stability. Eco-Friendly Wood Oil Finish: Coated with imported environmentally friendly wood oil, it preserves the natural wood grain beauty while forming a protective layer against UV-induced fading and cracking.
