The Light Grey Split Dual-Back Ergonomic Office Chair (model EOCH-SDB-001) from Bolongkeli Smart Furniture presents a streamlined, functional design tailored for modern work environments. Its cohesive light grey matte finish spans the split backrests, T-shaped fixed armrests, and five-star base, creating a understated, contemporary visual profile that blends seamlessly with neutral decor schemes. The chair follows a compact layout, with overall dimensions of 590 by 640 by 955 mm, featuring two 220 mm wide independent backrest pads, a 510 mm square seat, and armrests positioned 240 mm above the seat surface for consistent elbow support. Built for regular daily use, the chair combines durable, purpose-selected materials across its structure. The seat and backrests are upholstered in 0.8 mm thick light grey woven polyester fabric, with abrasion resistance rated to 50000 Martindale cycles, paired with a 40 mm thick high-resilience polyurethane foam seat cushion (45 kg/m³ density) and 30 mm thick molded polyurethane foam back padding. Structural components include a 2 mm thick steel mechanism plate, 12 mm plywood seat support, curved PP inner back frame with integrated flex points, injection-molded PP fixed T-armrests, glass-fiber reinforced nylon five-star base, and SGS-certified Class 3 steel pneumatic cylinder with 50 mm outer diameter. Dual-wheel non-marking PU casters with nylon hubs deliver smooth movement across hard and carpeted flooring, tested to 40000 rolling cycles, while the gas lift supports 100000 adjustment cycles, with a rated static user load capacity of 250 kg and net weight of 11 kg. Core functional features include 100 mm of seat height adjustment controlled via a side lever, 360-degree swivel rotation, a 30-degree rear rocking range with adjustable tension and three lock positions including a fixed upright setting, and split backrests that deliver independent spinal pressure distribution. The fixed T-armrests provide stable, non-adjustable upper limb support, and the easy-rolling casters enable simple repositioning between tasks. The chair is suited for diverse use cases: home office studies where its compact footprint fits limited space, open plan office workstations supporting 8-hour employee shifts, high-turnover co-working spaces where its neutral finish and durable fabric suit frequent shared use, student study desks for teen to adult users, and small meeting rooms where swivel and stable arm support facilitate short collaborative sessions, pairing well with a 2.4 m executive desk. For procurement planning, each chair ships in two cartons per set, with a packaged gross weight of 23 kg, total carton volume of 0.26 m³, and a reference assembly time of 40 minutes per unit. A 20GP container can hold 135 sets at 85% space utilization. Specification alignment checks should confirm the 500 mm fixed seat height meets intended user needs for the recommended maximum 1700 mm user height, and note the fixed, non-adjustable armrest design to ensure compatibility with existing desk clearances and user support requirements. The chair’s durable upholstery and robust structural components are selected to support consistent use across both private and shared work settings.
