This integrated injection molded plastic armchair features uniquely curved vertical slatted seat and backrest structure. The gap between slats brings outstanding natural ventilation, ensuring dry and breathable sitting experience even in hot weather without stuffiness. Made of high-density UV-resistant reinforced engineering plastic, it has excellent waterproof, sun-proof, anti-fading and anti-deformation properties, supporting long-term indoor and outdoor dual-use. The ergonomic curved back perfectly fits the human back curve to offer effective lumbar support. Integrated wrap-around armrests provide comfortable arm placement to relieve upper body fatigue. The overall structure can be stacked orderly for space-saving storage, suitable for home dining rooms, balconies, courtyards, as well as cafes, bistros, dessert shops and other commercial catering spaces with frequent layout adjustments. Matte anti-fouling surface is easy to clean; coffee spills, food residues and dust can be wiped clean quickly with a damp cloth. Non-slip protective foot pads at the bottom of chair legs prevent scratches on wooden floors, tiles and laminate floors and reduce sliding noise during movement. Minimalist modern streamline shape matches Nordic style, modern minimalist and light outdoor decorative styles perfectly.
