Seat cotton: Made of high-density cold-foamed shaped sponge, the curve conforms to the ergonomic principle. Length: 475mm, width: 435mm, thickness: 105mm, density: 50-55kg/m³. This ensures that the seat does not deform during long-term use, providing good comfort and resilience, and will never deform.

2. Back cotton: Made of high-density cold-foamed shaped sponge, the curve conforms to the ergonomic principle. Length: 700mm, width: 470mm, thickness: 150mm, density: 45-50kg/m³. This ensures that the seat does not deform during long-term use, providing good comfort and resilience, and will never deform.

3. Back inner panel: Made of high-quality plywood through mold injection molding, it has an arc-shaped appearance, is elegant and generous, and features a curving beauty. Length: 685mm, width: 425mm, thickness: 10mm.

4. Inner seat panel: Made of high-quality plywood through mold injection molding, it has an arc-shaped appearance, is elegant and generous, and features a curvilinear beauty. Length: 460mm, width: 425mm, thickness: 12mm.

5. Back shell: Made of high-quality PP (polypropylene) multi-element composite material through injection molding, it is resistant to high-strength impact and aging. Length: 770mm, width: 470mm, thickness: 2mm, with a 4mm thick and 6mm wide reinforcing rib around the periphery.

6 Seat shell: Made of high-quality PP (polypropylene) multi-element composite material through injection molding, it is resistant to high-strength impact and aging. Length: 480mm, width: 440mm, thickness: 2mm, with a 4mm thick and 6mm wide reinforcing rib around the edge.

7 Handrail frame: The handrail frame is made of 2.0mm thick cold-rolled steel plate. The front end design is an arc-shaped shape like a shell, formed by die stamping. The ground foot plate is made of high-quality 4.0mm thick steel plate, formed by stamping. The surface is treated with anti-rust, anti-fouling, spray coating and electrostatic spraying. The distance between the ground explosion installation holes is 190mm.

8 Central shaft: Made of high-quality solid iron with a diameter of φ14mm, it is durable.

9 Handrail cover: Made of imported oak, coated with polyester paint, length :415mm, width: 83mm, thickness: 25mm.

10 Fabric: Made of high-grade special fabric, it is wear-resistant, stain-resistant, anti-static and anti-fading.

11 Side panel: Made of high-quality high-density medium-density fiberboard, it is shaped by an engraving machine, with a thickness of 2mm.

twelve Writing board: The panel is made of high-density board formed in one piece, and the edges are sealed with high-quality injection molding. It has pen slots (160±1mm in length, 17±1mm in width, and 6±1mm in depth), which is convenient for placing pens. The panel specification is 265±1mm×255±1mm×15±1mm. The writing board mechanism adopts a new type of directly welded formed connection piece +14mm solid cold-drawn round iron bracket with 3mm cold-rolled steel plate welded. After the writing board bracket and the writing board are combined, they can bear a static pressure of ≥100KG. There is no deformation or fracture, thus ensuring that the writing board bracket and connecting parts will never be loose or deformed.

13 Seat bag: The seat bag's recovery is typically spring recovery, but it can also be made into gravity recovery or damping recovery, and it will never fail.

14. Ground fixation: Electrostatically sprayed hexagonal expansion screws are used, which are not prone to rust.
