Product Description

The EOF-WF-GM-01 ergonomic office chair from Bolongkeli Smart Furniture balances clean, modern visual design with supportive, purpose-built construction for long-duration seated use. Presented in a crisp neutral palette, the chair features a crisp white structural frame paired with light gray upholstered surfaces, anchored by a matching white five-star base for a cohesive, unobtrusive look that fits seamlessly across diverse interior schemes. Its high-back profile extends to a dedicated headrest, with smoothly contoured lines that avoid bulky, overly industrial visual weight to complement both contemporary commercial and residential spaces.
Durable, performance-focused materials form the core of the chair’s construction. The backrest uses light gray breathable polyester mesh to promote air circulation during extended use, while the seat pairs a 45 kg/m³ high-resilience injection molded foam core with light gray woven polyester upholstery, supported by a 12 mm thick molded plywood internal plate. The white frame is built from reinforced polypropylene, with the five-star base constructed from rib-molded reinforced nylon for structural rigidity. The central support column uses a black powder-coated steel Class 3 gas lift, paired with dual-wheel PU-coated nylon casters accented in white. Armrests feature soft PU padded surfaces for comfortable contact.
Built for flexible, user-centric function, the chair supports 360-degree swivel rotation and pneumatic height adjustment via a side lever, with 100 mm of vertical travel to align with standard desk heights. The synchronized recline mechanism offers a single-position lock and tension adjustment knob to accommodate different user weights, reaching a maximum recline angle of 135 degrees. The padded mesh headrest adjusts 70 mm in height and tilts 30 degrees to cradle the neck, while height-adjustable armrests offer 70 mm of vertical travel for customized upper body support. A contoured mesh back with fixed built-in lumbar curvature delivers consistent lower back support, and the dual-wheel casters roll smoothly across both hard flooring and carpeted surfaces. The chair supports a maximum recommended user weight of 136 kg, rated for 8 hours of daily use.
This model is well suited for private executive and administrative office workstations, residential home office and study spaces paired with standard 750 mm height desks, open-plan shared task workstations, and student study or public computing lab environments, with a recommended pairing with 2.4 m executive desks for optimal layout alignment. For procurement planning, each chair ships in two cartons, with a packaged gross weight of 23 kg per set, and requires 40 minutes of assembly per unit. A 20GP container can hold 135 sets at 85% space utilization, supporting efficient bulk ordering for large-scale workspace fit-outs. Teams planning deployments should confirm alignment with specific ergonomic requirements for intended user groups prior to large-scale purchase.
