Product Specification
1. Stylish and simple appearance – suitable for high‑end meeting rooms, auditoriums, small conference halls, screening rooms, multi‑functional halls, and other venues.
2. Ergonomic design – medium‑height backrest with continuous raised back and lumbar support shapes made of sponge, effectively alleviating fatigue from prolonged sitting.
3. Fully‑wrapped seat cushion – paired with an exquisitely crafted wooden backrest and seat board, making your venue stand out. The mechanical device prevents violent collisions, while the pneumatic function ensures maximum guest comfort.
4. High‑resilience PU foam – seat cushion density 60 kg/m³, back cushion density 55 kg/m³, integrally moulded and ergonomically designed for soft comfort, excellent resilience, and no deformation even after prolonged use.
5. Strong shell construction – seat and back shells made of polypropylene virgin resin pellets moulded as one piece, offering strong support and impact resistance. Inner lining uses seven‑layer hardwood plywood formed by high‑frequency and high‑pressure processes, providing additional strength and anti‑deformation properties.
6. High‑performance upholstery fabric – high‑quality fabric with strong permeability, excellent sound absorption, wear resistance, colourfastness, and moderate softness. Easy to clean; colours and textures customisable. Optional treatments include 3M stain resistance, Teflon liquid/dust repellency, anti‑static, anti‑bacterial, anti‑mildew, and flame‑retardant properties. Meets Chinese standards GB8410‑94 and GB17951‑1998, as well as British standards BS7176 and BS5852.
7. Robust standing legs – utilise “Zhuang” brand products, surface‑treated with oil removal, rust removal, acid pickling, phosphating, and electrostatic powder coating. Foot bases are cold‑rolled steel plate stamped to shape with a thickness of no less than 2.4 mm. Frames, supports and legs receive anti‑rust treatment, followed by an 18‑micron electrophoretic primer and a 30‑micron epoxy resin spray coating. This ensures 400‑hour salt spray resistance or 100‑hour salt bath without rusting, with paint film adhesion exceeding Grade 2 and certified test reports.
8. Silent gravity‑damping return – advanced gravity plus imported damping device ensures smooth, zero‑noise retraction (< NR‑20), with over 200,000 trouble‑free cycles for the return mechanism and over 50,000 for the damping unit. Floor anchor screws and all metal parts are anti‑corrosion treated to standard. Optional luminous row and number plates (no power supply, wiring, or maintenance required) are available.
Note: The drawing also includes a second 970 mm value; this may indicate additional height reference or row spacing – please consult the original drawing for confirmation. Writing board dimensions are not specified in the supplied drawing; contact sales for details.
Detailed Specifications
Upholstery fabric – High‑quality fabric with strong permeability, excellent sound absorption, wear resistance, colourfastness, and moderate softness. Easy to clean, colours and textures can be customised according to client requirements. Additional treatments are available upon request, such as 3M stain resistance, Teflon liquid and dust repellency, anti‑static, anti‑bacterial, anti‑mildew, and flame‑retardant properties. Flame retardancy meets Chinese standards GB8410‑94 and GB17951‑1998, as well as British standards BS7176 and BS5852.
Seat and back cushions – Made of polyurethane foam moulded in one piece, designed according to ergonomic principles for a soft, comfortable feel with excellent resilience. The cushions do not deform even after prolonged use. Seat cushion density is 60 kg/m³, back cushion density is 55 kg/m³.
Seat and back shell – Made of polypropylene virgin resin pellets moulded in one piece, providing strong support, impact resistance, and durability. The inner lining of the seat and back is made of seven‑layer hardwood plywood, formed by high‑frequency and high‑pressure processes, offering strong support, impact resistance, and anti‑deformation properties.
Standing legs – Made of “Zhuang” brand products, surface treated with oil removal, rust removal, acid pickling, and phosphating, followed by electrostatic powder coating. The foot base is formed from cold‑rolled steel plate via stamping, with a thickness of no less than 2.4 mm. The chair frame, seat support, and chair legs undergo anti‑rust treatment, followed by 18‑micron electrophoretic coating for anti‑corrosion primer protection, and then 30‑micron epoxy resin spraying. This ensures corrosion resistance for 400 hours in salt spray or 100 hours in salt bath tests without rusting. The paint film adhesion exceeds Grade 2, and qualified test certificates are provided.
Armrests – Armrest surface is made of moulded wood with a cherry wood finish (colour options available).
Writing tablet – A flip‑down writing tablet is attached to the back of the chair, making efficient use of space. Made of melamine board with colour options available.
Return mechanism – Utilises an advanced gravity plus damping return mechanism, ensuring smooth and coordinated retraction with zero noise. It is designed for over 200,000 trouble‑free cycles. Equipped with an imported damping device, it operates completely silently (< NR‑20) and is rated for over 50,000 trouble‑free cycles.
Floor anchor screws – All screws, metal components, and chair leg screws undergo standard anti‑corrosion treatment. Metal parts such as chair legs are treated for rust and corrosion resistance.
Number and row plates – Optional luminous row and number plates are available (require no power supply, wiring, or maintenance).
