The Light Gray Frame High-Back Segmented Mesh Ergonomic Office Chair, model ERG-OFC-LG-SEG01 from Bolongkeli Smart Furniture, presents a streamlined professional silhouette anchored by a cohesive light gray structural palette. Its tall segmented backrest flows into a matching height-adjustable headrest, paired with fixed padded armrests and a wide five-star base, creating a balanced, unobtrusive form that complements contemporary interior schemes without visual clutter. Built for long-term regular use, the chair’s frame and five-star base are constructed from reinforced PA nylon with glass fiber reinforcement for the backrest frame, paired with a breathable dual-layer polyester mesh back upholstery. The seat incorporates a plywood internal support board, topped with high-density cold-cured molded polyurethane foam wrapped in breathable laminated woven polyester fabric. Armrests use light gray PP support posts capped with soft PU padding, while the SGS-certified Class 3 steel gas lift connects to mute PU soft-wheel casters suitable for both hard flooring and carpeted surfaces. Core functional features are tailored to comfortable extended seating: a side lever controls 130mm of vertical seat height travel, complemented by a 30-degree backrest recline with upright lock, and an under-seat rotating knob to adjust tilt tension for different user weights. The headrest offers both height adjustment and angular tilt for customized neck support, while the curved segmented lower mesh section delivers passive contoured lumbar support. Full 360-degree swivel and smooth rolling casters enable easy repositioning, with a maximum recommended user weight of 136kg to accommodate a broad range of users. This chair fits seamlessly across diverse residential and commercial settings: it supports 8 hours of daily workstation use in open-plan offices, offers a professional polished look for executive private offices, stands up to frequent multi-user turnover in co-working spaces, sustains comfort through long conference room meetings, aligns with the aesthetic of modern home offices, and pairs effectively with height-adjustable sit-stand desks. For procurement planning, note that each unit ships across two cartons, with a reference assembly time of 40 minutes per set, allowing teams to accurately project installation timelines and freight volumes for bulk orders, as the durable commercial-grade components are engineered to hold up to consistent high-traffic use across shared and dedicated workspaces.
