The Split Dual-Back Ergonomic Office Chair with Adjustable Headrest, model EOCH-SB320-LBGR from an unbranded line, features a refined two-tone light blue and light grey palette suited to contemporary work environments. Its visual design centers on distinct split dual back panels paired with a smoothly contoured seat and matching padded headrest, supported by a sleek five-star base for a balanced, professional silhouette that avoids bulk. The chair measures 610 x 705 x 1320 mm overall, with proportional dimensions that align with standard office desk setups without overwhelming surrounding space. Construction prioritizes durability and long-session comfort: the backrest uses breathable light blue polyester mesh to support air circulation, while the 50mm thick, 45 kg/m³ density molded polyurethane foam seat is upholstered in light grey woven polyester fabric with a 45% rebound rate to reduce pressure buildup. The headrest carries 20mm thick high-density foam wrapped in matching light blue mesh. Structural components include a glass-fiber reinforced nylon PA+GF five-star base with light grey finish, Class 4 steel gas lift with 85mm stroke, 2.5mm thick steel plate tilt chassis, fixed curved engineered PP plastic armrests in white and light grey, and 50mm grey PA nylon dual-wheel casters. Key performance ratings include a 136 kg maximum recommended user weight, 1200 kg five-star base static load rating, 100,000-cycle caster rolling durability, and 120,000-cycle backrest tilt fatigue rating, with a net weight of 25 kg. Core functional features include pneumatic seat height adjustment with 60mm total travel for a 500mm adjustable seat height, synchro-tilt backrest recline up to 145° with multi-position lock, 360° swivel, height and angle adjustable headrest for targeted neck support, and independent dynamic lumbar support from the split back panels. Fixed curved armrests sit 180mm above the seat to support forearms at desk height, while dual-wheel casters glide smoothly across hard floors and low-pile carpet. This chair is suited for a wide range of workspaces: private and executive offices supporting 8+ hours of daily seated work at standard 760mm height desks, home offices where its neutral color scheme complements modern residential interiors, open-plan workstations where its low-profile armrests tuck neatly under standard desk surfaces, corporate conference rooms where swivel and caster mobility enable easy collaborative movement, and coworking hot desks where adjustable features accommodate diverse user body types. For procurement, note that each unit ships across 2 cartons with a total packaged gross weight of 23 kg and total carton volume of 0.26 m³, with an 40-minute assembly time per set. A 20GP container can hold 135 sets at 85% space utilization, for large-scale deployment planning.
