The High-Back Ergonomic Mesh Office Chair with Adjustable Headrest, model KL-08A/B-MESH-OFC, is an unbranded ergonomic office seating solution designed for balanced support and versatile commercial and residential use. Its streamlined, professional silhouette features a tensioned polyester mesh backrest paired with a black woven polyester fabric seat, supported by a matte black plastic frame, reinforced nylon five-star base, and black polyurethane casters. The fixed padded armrests sit 240mm above the seat surface, with 540mm of clear space between them to accommodate a range of body types, while the contoured, foam-padded headrest and integrated rigid contoured lumbar zone align with the natural curve of the spine for upright seated posture. At full assembly, the chair measures 680 x 670 x 1050 mm, with a 90mm thick seat cushion built on 40mm high-density molded foam and 70mm of backrest padding, creating a compact footprint that integrates seamlessly into standard workspace layouts. Construction prioritizes long-term durability for frequent use, with a 2.0mm cold-rolled steel tilt chassis, Class 3 steel gas lift with 50mm outer diameter, 2.5mm wall thickness reinforced nylon base, and 50mm diameter polyurethane casters rated for 40000 rolling cycles. The mesh and fabric upholstery delivers 50000 Martindale cycles of abrasion resistance, while the full chair weighs 18kg for easy repositioning. Key functional features include pneumatic lever-operated seat height adjustment with 100mm vertical travel, synchro-tilt backrest movement with 15 degrees of recline and upright position lock, 360-degree full swivel around the central gas lift, and smooth, quiet 360-degree caster movement suitable for all floor types. The chair supports a maximum user weight of 150kg, with ergonomic zoning calibrated for 8+ hours of daily desk work. This model is suited for a wide range of spaces: private office workstations, open-plan office task areas where its neutral black finish aligns with standard commercial fit-outs, home office workspaces where its compact size fits 1200mm wide desks, conference rooms where its smooth swivel and quiet casters support natural movement during discussions, shared hot-desking environments where durable upholstery stands up to multi-user wear, and training rooms where its lightweight design allows quick repositioning between sessions. For procurement, note that each unit ships in 2 cartons with a total packaged gross weight of 23kg and total carton volume of 0.26 m³, requires 40 minutes of assembly per set, and fits 135 units per 20GP container at 85% space utilization, making it a practical choice for bulk and individual orders alike.
