Product Specification
1. The seats are designed based on ergonomics and aesthetics, with backrest and seat cushions curved to fit the human body, providing comfortable seating. The seat height and depth are reasonable, and the appearance is simple and elegant.
★2. Basic center distance: 560±10mm, seat side depth: 440±10mm, writing board side depth: 790±10mm, chair height: 920±10mm, minimum row spacing: 900mm.
★3. Under-seat retractable writing board: The connecting aluminum head and bracket are made of high-quality aluminum alloy through integrated die-casting, and the panel is made of ABS composite material through integrated injection molding. They are fixed with high-strength bolts, becoming tighter with use. Dimensions: 381.2±2mm × 261.2±2mm × 12mm. The armrest and writing board are tilted upward at 6.5° for natural writing. The opening and closing mechanism includes a noise-reducing function, with no rebound or noise.
4. The fabric is high-grade knitted cloth, treated with anti-static and anti-moth properties, durable, wrinkle-resistant, and colorfast.
5. The foam is polyurethane cold-cured high-resilience sponge. Seat cushion density: 40-55Kg/m³, back cushion density: 35-45Kg/m³, 75% compression permanent deformation rate ≤3%. It offers good resilience, high strength, and antibacterial properties.
★6. The aluminum alloy armrest frame is made through integrated die-casting, polished, and treated with anti-oxidation. The stand design is agile and stable, with a built-in recessed writing board storage structure. Armrest thickness: 57±2mm, height: 650±2mm, length: 435±2mm, with a curved surface. The side panels are made of anti-stain fabric composite with 3MM medium-density fiberboard.
7. The armrest cover is made of imported solid oak wood, with a curved design that resists deformation. Dimensions: 360±2mm × 58.5±2mm × 50±2mm.
8. The seat uses a damping return mechanism with two-stage buffering (fast first, then slow), resetting within 3 seconds. It includes an escape noise reduction feature and anti-collision rubber pads, ensuring quiet opening and closing and gentle return.
9. The inner panels of the seat and backrest are made of 15±2mm plywood bent and molded, while the outer panels are made of high-density hardwood multi-layer board cold-pressed and molded, resistant to deformation and fading. Outer seat panel dimensions: 410±5mm × 400±5mm × 10±5mm, outer back panel dimensions: 592±5mm × 465±5mm × 15±5mm, ensuring durability.
10. Hidden expansion screws are used for floor fixation, with plastic dust covers included. The chair legs are flat, aesthetically pleasing, and easy to clean.
