1. Seat cotton: Made of high-density PU cold-foamed shaped cotton, length: 500mm, width: 455mm, thickness: 155mm, density: 55-60kg/m³.

2. Back cotton: Made of high-density cold-foamed shaped sponge, the curve conforms to the ergonomic principle. Length: 740mm, width: 450mm, thickness: 130mm, 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 curvilinear beauty. Thickness: 6mm.

4. Back and outer panel: Made of high-quality high-density hardwood multi-layer board through mold injection molding, it has an arc-shaped appearance, is elegant and generous, and features a curving beauty. Length: 750mm, width: 515mm, thickness: 15mm.

5 Outer panel of the seat: Made of high-quality high-density hardwood multi-layer board through mold injection molding, length: 430mm, width: 420mm, thickness: 15mm.

6 Handrail frame: The handrail frame is made of 2.0mm thick cold-rolled steel plate. The front end design adopts an arc-shaped shape like a shell, which is formed by die stamping. The vertical pipe is made of 80*40*T1.2mm high-quality steel pipe. After welding and forming, it undergoes processes such as grinding, rust removal and phosphating, electrostatic powder coating, and high-temperature oven treatment. The base plate is made of high-quality 2.0mm thick cold-rolled steel plate through stamping. The base plate fixing parts and the base plate are formed by one-time stamping and stretching, which is more beautiful and firm than conventional welding. The surface is treated with anti-rust, anti-fouling, spray coating and electrostatic spraying. The distance between the two holes is 235mm.

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

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

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

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

11 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.

twelve Seat frame: Made of 1.5mm thick cold-rolled steel plate through die stamping, 7mm thick plywood is nailed to the surface of the iron frame to ensure the firmness of the chair seat and long-term use without failure.

13 Return function: The seat bag adopts A damping recovery mechanism (torsion spring and damper), with noise as low as A-weighted sound level (≤30DB), ensuring no impact during recovery. Sound-absorbing small holes are made on the seat surface to enhance the sound absorption function of the seat, making it convenient for use in occasions with high requirements for audio effects.

14. Ground fixation: Electrostatically sprayed hexagonal expansion screws are used, which are not prone to rust. With an additional dust cover, it looks elegant and stylish.
