1. Chair frame: The steel frame is made of round square pipe 19.2*32.3*T1.5mm high-quality Q235 carbon steel pipe, fully automatic robotic arm welding, strong stability, the surface is treated by high-speed sanding and rust removal, and the high-temperature baking paint spraying process is adopted, the paint surface is firm, no paint stripping, and 2 steel wires are protected to increase the tensile force.
2. Back: new PP+25% glass fiber, integrated injection molding, elastic waist support curve design, upper and lower double-layer backrest shape to achieve the support points of specific parts such as thoracic spine and lumbar spine, effectively protect the waist and back, prevent the sub-health risk of sitting for a long time, and the upper end of the backrest is designed with a handle to facilitate movement. The implicit free structure allows the back of the chair to lean back 12°±2 within a certain range, and the thickened fine hole 300 square gram mesh fabric is selected, which is breathable and tensile strong, and a thrust of 60kg is applied to it, which is maintained for 60s without abnormality
3. Seat seat: using a national standard sponge with a density of 68 and a hardness of 45, weighing 0.58kg, using a high-elasticity and breathable 280 square grams of seat cloth, comfortable and breathable, with a PP engineering plastic dustproof bottom shell. The 24-hour formaldehyde emission is less than 0.120 mg/m2 · h, which meets the QB/T 2280-2016 test standard
4. Handrails: It can slide back and forth 2.5cm, which can meet different sitting postures and crowds, and effectively relieve fatigue.
5. Foot plug: Nylon rubber plug design is used to increase ground contact, anti-slip and wear-resistant
6. Function: The cushion is turned up, folded and stored to save space
7. Writing board: using high-quality PP+30% glass fiber thickened board surface, aluminum alloy bracket with fine polishing aluminum alloy rotation mechanism, can be flexibly rotated and retracted. Load-bearing capacity of 20KG, with ergonomic design of pen tray and cup position
