The MBM-FA-650 Mesh Task Chair is an unbranded mid-back ergonomic office task chair designed to support comfortable seated posture across daily work and meeting scenarios. The chair features a streamlined, functional silhouette with a contoured mid-back structure, fixed flat-top armrests, and a five-star rolling base that balances a compact footprint with stable, unrestricted movement. Its clean black finish integrates seamlessly across varied interior design schemes without visual clutter. Constructed for long-term regular use, the chair pairs a breathable polyester mesh backrest with a high-density molded polyurethane foam seat, supported by a 12mm plywood seat core and wrapped in breathable woven mesh fabric. Its frame is built from reinforced nylon blended with 15% fiberglass, matched with fixed black polypropylene armrests and a reinforced injection-molded nylon five-star base. The seat cushion holds a thickness of 60mm with a foam density of 45 kg/m³, delivering consistent support, while 60mm twin-wheel nylon casters, a steel hydraulic pneumatic cylinder, and durable mesh upholstery rated for 50000 Martindale abrasion cycles support extended use in high-turnover settings. Core functional features address core office seating needs: a 100mm stroke pneumatic seat height adjustment controlled via an under-seat lever reaches a maximum seat height of 520mm, paired with full 360-degree swivel from the central gas-lift joint. A built-in contoured lumbar support is integrated into the mid-back section to maintain natural spinal alignment, while the lockable tilt mechanism offers up to 12 degrees of backward recline with adjustable tension control and a single upright lock position for focused desk work. The fixed armrests sit 180mm above the seat to support forearms during typing, and the casters roll smoothly on hard floors including wood and tile, as well as low-pile carpet, with tested caster durability for repeated daily use. The chair supports users up to 136kg, and is calibrated to support ergonomic posture for adults up to 185cm tall. This model fits a broad range of commercial and residential spaces: it works for standard office workstations paired with 760mm height work surfaces, fits compact home studies and small home office desks, serves as practical conference room seating for short to medium duration meetings, and stands up to the demands of high-traffic open-plan shared work areas. Procurement teams and individual buyers should note the chair ships in two cartons per set, with a reference assembly time of 40 minutes per unit, and a packaged gross weight of 23kg per set. For large-scale commercial orders, 135 sets fit in a 20GP container at 85% space utilization, supporting efficient bulk deployment.
