performance and characteristics

►►The soft core of the chair back and seat is made of high-quality polyurethane material by cold foaming and high resilience process, with S-shaped spring built in. The density of the back cushion is 57kg/m3, and the density of the seat cushion is 65kg/m3. Its curved surface modeling is designed according to the principle of human body engineering, using artificial cloth refined processing, elegant appearance, comfortable seat, moderate hardness, high rebound unchanged.

►►The back plate and seat plate are made of wooden multi-layer board and high-frequency compression molding. The skin is beech skin (the skin can be selected according to user requirements), and the outer surface is coated with high-frequency polyester polishing paint. The shape is beautiful and elegant. Due to the high-frequency compression molding, it will not crack for long-term use and has good moisture-proof function. The back plate is molded of multi-layer board, and the seat plate is provided with sound-absorbing holes.

►►Streamlined conjoined handrails, high-quality wood, high-frequency pressing molding, good material stability, no deformation, no cracking, beautiful appearance, according to the needs of users to choose wood.

►►Fabric selection of high-quality high-grade fabrics, there are a variety of colors for users to choose, and anti-static, mothproof treatment, long-term use without wrinkles, fracture, pilling, fading phenomenon. The fabric is treated with flame retardant, and its flame retardant performance is tested according to international methods. All performance indexes can meet the B1 level requirements of the combustion performance judgment conditions for decorative fabrics in the Code for Fire Protection Design of Interior Decoration of GB50222-95 Buildings, and its combustion performance is the B1 level standard.

►►The chair seat is turned over by using torsion spring frame damping rebound device, with built-in slow rise and damping device. The rebound is noiseless and accurate. The structure is designed by the company's patent. The seat surface turnover test shall reach 200000 times, and the durability test of the seat (including damping device) shall reach 50000 times or more.

►►The chair leg is a single-leg air supply column, which adopts a load-bearing circular tubular air supply structure. The air supply device is composed of double-layer perforated steel pipes. The air inlet of the inner perforated steel pipe is provided with an air flow regulating plate to slow down the wind speed, reduce noise and balance the wind pressure of each tuyere. It is stamped from a metal plate and fixed with bolts and the ground. Air supply volume: 50m 3/h; Wind speed: V≤ 0.1 m/s; Noise: ≤ 12 Db;C the air supply area of the adjusting plate is 7800 ㎡, 7510 ㎡, 7200 ㎡ and 6930 ㎡ respectively. Four adjustable air supply area, can make the air supply effect to achieve a better state. The unit air volume of the adjusting plate is 17.81 ㎝ 3/㎜ 2-20.04 ㎝ 3/㎜ 2 per second, which can meet the requirements of noise standard and pressure loss. The upper half of the load-bearing and scattered air duct exposed to the ground is convenient for installing the metal part of the chair and all parts of the overall chair, which can bear more than 250kg.

►►All metal surfaces of the seat are electrostatic spray after sandblasting and derusting treatment. It has salt bath resistance, impact resistance, strong adhesion, corrosion resistance, smooth surface, beautiful appearance and durability.

►►The back and seat cushion have a sound absorption effect. The back of the seat back has a sound reflection effect, and the bottom of the folded seat has a sound absorption effect. The bottom surface of the seat is made of perforated plate, which has good sound absorption effect.

►►The seat number is embroidered on the back of the seat, and the row number is arranged on the side of the seat at each port.
