Product size requirements:

Foot size requirements:

The connection of the writing board is die-casted with the aluminum alloy feet, making the writing board more sturdy and durable. A sample of the aluminum alloy feet is required.

Technical requirements:

1. Seat width (center in the armrest): 580mm, total seat height: 990±10mm, seat height: 450±10mm. Seat depth: 823±10mm, armrest height 662±10mm: minimum row spacing: 900mm.

2. Writing board: The panel is made of ABS composite material and is formed by a mold in one step. The thickness is 9±2mm. The shaft adopts a unique positioning device, and the supporting rotating structure is made of zinc alloy injection molding. The length is 360±2mm and the width is 280±2mm. The armrest cover and writing board are tilted upward by 6.5 degrees to ensure a comfortable and natural writing state.

3. The fabric is made of high-grade knitted fabric and has been treated with anti-static and anti-moth treatment. It feels comfortable and will not wrinkle, break, pilling or fade after long-term use.

4. The seat foam is polyurethane cold foam high-resilience shaping sponge. Seat sponge size: Seat sponge: High-density cold foam PU shaping sponge. The seat sponge length is 480±10mm, the width is 475±5mm, the height is 140±10mm, and the sponge density is 40-55KG/M3. Back sponge size: Back sponge: High-density cold foam PU shaping sponge is used. The upper back sponge length is 480±5mm, the width is 300±5mm, the height is 100±5mm, the lower back sponge length is 480±5mm, the width is 450±5mm, the height is 100±5mm, and the sponge density is 35-45KG/M3. High strength, good resilience, unique formula, make the foam antibacterial, can effectively kill bacteria such as Escherichia coli.

5. The seat armrest is made of aluminum alloy mold high temperature one-time die casting, cathode electrophoresis (black) and then fine polishing, weighing 2.9KG.

6. Seat back outer panel: Back outer panel: Made of high-quality high-density hardwood multi-layer board, cold-pressed and injection-molded by mold, no fading, and anti-deformation. Upper back outer panel specifications: length 490±2mm, width 285±2mm, thickness 15mm, lower back outer panel specifications: length 490±2mm, width 425±2mm, thickness 15mm. Back inner panel: Made of high-quality plywood, pressed and bent by mold. The appearance is arc-shaped, beautiful and elegant, with curvaceous beauty. Upper back inner panel size specifications: length 420±2 mm, width 265±2mm, thickness 6 mm, lower back inner panel size specifications: length 420±2 mm, width 405±2mm, thickness 6 mm. Seat iron frame: Made of high-quality steel plate, stamped and welded, 5 S-shaped snake springs are welded on the sponge contact surface to ensure that the seat is comfortable and elastic. Dimensions: length 420±2mm, width 410±2mm, height 56±2mm.

7. The seat adopts a damping return mechanism, and a rubber pad is added to the seat return collision part to prevent collision and reduce noise, so that the seat opens without noise and returns slowly without impact.

8. Chair feet: The foot tube is made of high-quality square tube, and the foot tube is made of high-quality steel plate. It is pressed by mold and then welded with carbon dioxide. The appearance is a single-foot under-ventilation structure device. The surface is rust-removed, cleaned, oxidized, dried, electrostatically treated, high-temperature treated, and statically sprayed matte black. The dimensions are: length 495±2mm, width 285±2mm, and height 300±2mm.

9. The seat is fixed to the ground with hidden pressure-explosive screws, and the appearance is specially designed with a plastic dust cover to ensure that the chair legs are smooth and beautiful while preventing dust accumulation and facilitating cleaning.
