The Mid-Back Mesh Ergonomic Office Task Chair (model MB-FA-MESH-059) is an unbranded professional seating solution designed for versatile commercial and residential workspaces. Visually, it features a clean, streamlined silhouette with a neutral black finish that aligns with most commercial interior design schemes, paired with a structured mid-height backrest, fixed curved armrests, and a wide five-prong base for a balanced, professional appearance. Its overall dimensions of 590 x 640 x 1060 mm create a compact footprint that integrates seamlessly into standard desk layouts without excessive visual bulk. Constructed for long-term regular use, the chair pairs a tensioned breathable polyester mesh backrest set over a durable nylon frame, with an integrated molded nylon lumbar support structure positioned to align with the natural curve of the lower back. The seat features a 45kg/m³ high-density molded PU foam core with 40% rebound rate, upholstered in wear-resistant polyester fabric, supported by a 12mm thick plywood inner panel. Fixed curved PP armrests with padded top surfaces sit 180 mm above the seat, while the base uses a reinforced black nylon five-prong design with 700 mm diameter, fitted with 60mm black PU dual-wheel swivel casters and a black-finished Class 3 steel pneumatic gas lift. All structural components are engineered for durability, with tested load capacities and cycle ratings suited to daily multi-user use, supporting a maximum recommended user weight of 120 kg. Functional features support comfortable, flexible seated work: a side under-seat lever controls pneumatic seat height adjustment with 100mm travel, the seat and back junction enables 360-degree full swivel rotation, and a synchro-tilt mechanism offers adjustable rocking tension with a single-position lock at a 12 degree maximum backrest recline. The PU casters roll smoothly across hard floors and low-pile carpet, while the fixed contoured lumbar support and padded armrests reduce strain during extended sitting. The breathable mesh back prevents heat buildup for all-day comfort, and the seat dimensions (510 mm width, 440 mm depth) accommodate 90th percentile adult users for full-shift use. This chair is suited to a wide range of spaces: it fits standard 1200mm open office workstations and cubicle employee seating, works reliably for home office extended work sessions, presents a polished look for conference room guest seating, supports easy repositioning during training room activities, and blends seamlessly into reception visitor areas. For procurement, note that each unit ships in 2 cartons with a total packaged gross weight of 23 kg and 0.26 m³ volume, requires 40 minutes of assembly per set, and allows 135 sets to be loaded in a 20GP container at 85% space utilization, making it a practical choice for both small-scale and bulk furnishing projects.
