Product Specification
1. The seat is designed based on ergonomics and aesthetics, with the curvature of the backrest and seat cushion conforming to the human body's natural curves. The armrest frame, base foot, and leg tubes are made of high-quality hot-rolled steel plates through stamping or welding, with a surface treated with rust-proof electrostatic matte black spray. The seat height and depth are reasonable, providing a comfortable sitting experience, and the seat cushion features an automatic return function.
2. The basic center distance is 540±5mm, the seat depth on the open side is 607±5mm, the writing board depth on the open side is 769±5mm, the chair height is 923±5mm, and the minimum row spacing is 850mm.
3. The writing board bracket and aluminum head are made of high-quality aluminum alloy through integrated die-casting, finished with polishing, spraying, and electrophoresis treatment. The board surface is available in painted board or plastic board, with dimensions of 250×264×15mm.
4. The fabric is made of high-grade knitted cloth, treated with anti-static and mothproofing, ensuring durability, wrinkle resistance, and resistance to pilling and fading.
5. The seat cushion and backrest use polyurethane cold-foam high-resilience sponge, with densities of 40-55kg/m³ and 35-45kg/m³ respectively, offering antibacterial properties, resistance to deformation, and excellent resilience.
6. The steel structure is made of high-quality steel, welded by robots, with a surface treated through degreasing, phosphating, and electrostatic spraying processes, ensuring strong corrosion resistance.
7. The armrests are made of imported oak with a curved design, measuring 278×50×41mm.
8. The seat cushion is equipped with a damping return mechanism, featuring two-stage buffering to achieve silent and smooth reset within 3 seconds. Rubber pads are added at collision points to reduce impact noise.
9. The inner panels of the seat and backrest are made of 15mm thick high-quality plywood, formed through bending. The outer panels are made of high-density hardwood multi-layer boards, cold-pressed and injection-molded, ensuring no deformation, no fading, and providing durability and quiet operation.
10. The stand feet are made of 1.5mm thick hot-rolled steel plates, welded and formed, with a matte black electrostatic spray finish, measuring 595×333×50mm.
11. Installation uses hidden expansion screws fixed to the ground, accompanied by plastic dust covers for an aesthetically pleasing and easy-to-clean appearance.
