The Ergonomic Mesh Office Chair with Dual Split Back, Headrest and Retractable Footrest (model OFC-ERG-DB-FT-001, unbranded) features a streamlined, functional high-back profile defined by a clean black mesh finish and polished aluminum accents, designed to balance visual polish with user-centric ergonomic structure. Its layout centers on two independent vertical back panels, paired with a curved adjustable headrest, contoured seat, and under-seat retractable footrest that stays fully hidden when not in use, creating an uncluttered silhouette suited to both professional and residential work environments. Constructed for long-term regular use, the chair uses breathable black elastic mesh for seat and back upholstery, supported by a glass-fiber reinforced nylon internal frame and 14 mm bent plywood seat support board. The five-star base is polished die-cast aluminum, fitted with black polyurethane dual-wheel casters, soft polyurethane armrest pads mounted on nylon supports, and a chrome-plated steel Class 3 gas lift. Contact points feature targeted padding: high-density polyurethane foam for the headrest, 60 mm thick seat foam with 45 kg/m³ density and 65% rebound, with finished seat cushion thickness reaching 90 mm and backrest padding thickness at 70 mm. The fabric-padded retractable footrest uses a steel sliding mechanism for smooth operation. Core functional features are engineered to reduce seated fatigue across long shifts: the dual split back flexes independently to conform to natural spine curvature across a 240 mm tall lumbar support zone, while pneumatic seat height adjustment delivers 100 mm of travel controlled via a side lever. The backrest reclines to a 125 degree maximum angle with an adjustable tension knob, and the 380 mm pull-out footrest supports rest breaks. The chair enables 360-degree swivel rotation, with casters that roll smoothly across hard floors and low-pile carpet. It supports a maximum user weight of 150 kg, with mesh tested to 50000 abrasion cycles and casters rated for 100000 rolling cycles. Overall dimensions measure 680 x 680 x 1280 mm, with 540 mm of clear width between armrests, and a product net weight of 23 kg. This chair fits a wide range of work settings: it delivers targeted support for 8+ hour shifts in corporate open plan offices and call center workstations, its compact footprint works for home office setups, its polished base pairs with premium furnishings in executive private offices (optimally matched with a 2.4 m executive desk), and its adjustable, robust build suits diverse users in shared coworking spaces. For procurement, note each unit ships in 2 cartons, requires 40 minutes of assembly per set, and 135 sets fit a 20GP container at 85% space utilization, with packaged volume of 0.26 m³ per set.
