Product Specification
Ergonomic contour, versatile backrest styles & silent return – Backrest and seat cushion follow natural body curves, and a wide variety of backrest shapes are available. The advanced gravity plus damping return mechanism ensures coordinated, zero‑noise motion (<NR‑20) and trouble‑free performance for over 200,000 cycles (with imported damper, over 50,000 cycles).
High‑density polyurethane foam – Both seat and back cushions are one‑time moulded polyurethane foam conforming to ergonomic principles, offering soft comfort and excellent resilience. Seat cushion density is 60 kg/m³, back cushion density is 55 kg/m³, maintaining shape even after prolonged use.
Durable PP shell with steel‑reinforced seat – Seat and back shells are injection‑moulded from virgin polypropylene plastic with a thickness of no less than 4mm, providing strong support, impact resistance, and deformation resistance. The seat board is internally reinforced with a steel frame for extra strength.
Premium multi‑functional fabric – High‑quality fabric with strong permeability, excellent sound absorption, wear resistance, colourfastness, and easy cleaning. Colours and textures can be customised. Optional treatments include 3M soil resistance, Teflon liquid/dust repellence, anti‑static, antibacterial, anti‑mildew, and flame retardancy meeting Chinese GB8410‑94, GB17951‑1998 and UK BS7176, BS5852 standards.
Robust "Pearl Steel" base & anti‑corrosion finish – The base is made from cold‑rolled steel plates (≥2.4mm) with degreasing, derusting, pickling, phosphating, and electrostatic powder coating. Chair frames and legs receive an 18‑micron electrophoretic primer plus 30‑micron epoxy resin spray, passing 400‑hour salt spray or 100‑hour salt bath tests without rusting, with adhesion exceeding Level 2.
Rotatable armrests with cup holders – Armrests are equipped with integrated cup holders and can be rotated up and down for added comfort and convenience.
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 determined according to customer requirements. Optional treatments include 3M soil resistance, Teflon liquid and dust repellence, anti‑static, antibacterial, anti‑mildew, and flame retardancy. The flame retardant effect meets Chinese standards GB8410‑94 and GB17951‑1998, as well as UK standards BS7176 and BS5852.
Damping mechanism – Advanced gravity plus damping return mechanism ensures coordinated and consistent return motion with zero noise (<NR‑20) and trouble‑free operation for over 200,000 cycles. With an imported damping device, it guarantees trouble‑free performance for over 50,000 cycles.
Automatic return – The seat cushion automatically returns to the upright position when not in use, ensuring a tidy and safe aisle.
Seat & back cushions – Made of polyurethane through one‑time foam moulding, conforming to ergonomic principles, offering soft, comfortable, and resilient seating. The seat cushion density is 60 kg/m³, and the back cushion density is 55 kg/m³, maintaining shape even after prolonged use.
Seat & back shells – Injection‑moulded from virgin polypropylene plastic pellets with a thickness of no less than 4mm, providing strong support, impact resistance, and deformation resistance. The seat board is internally reinforced with a steel frame for enhanced support and durability.
Base/legs – Constructed from selected "Pearl Steel" product. The surface undergoes degreasing, derusting, pickling, and phosphating before electrostatic powder coating. The foot base is stamped from cold‑rolled steel plates of no less than 2.4mm thickness. Chair frames, seat supports, and legs receive anti‑rust treatment, followed by an 18‑micron electrophoretic anti‑corrosion primer and a 30‑micron epoxy resin spray, ensuring the coating passes 400‑hour salt spray tests or 100‑hour salt bath tests without rusting. Coating adhesion exceeds Level 2, with qualified test certificates.
Armrests – Equipped with integrated cup holders and can be rotated up and down for comfort and convenience.
Floor fixing screws & metal parts – All screws, metal components, and chair leg screws undergo anti‑corrosion treatment according to standards. Metal parts such as chair legs receive anti‑rust and anti‑corrosion treatment.
