Product Description

The Black Mesh Mid-Back Swivel Task Chair with Fixed Arms is a practical office seating solution designed for regular desk-based work. Model OC-MB-FA-50B is supplied unbranded, presenting a clean, neutral appearance that fits easily into coordinated commercial and residential work environments. Its visual character is defined by a gray-black woven flexible mesh back set within a black molded polymer frame. The mid-back form includes a structured lumbar support zone, while the black seat uses woven fabric over a rounded-edge molded foam cushion. Black T-shaped fixed polymer armrests with flat pads and vertical supports frame the seating area, and the black five-prong caster base reinforces the chair’s functional, understated profile. A chrome-plated telescoping gas lift with a black lower shroud provides a subtle metallic accent. The chair measures 610 by 620 by 1010 millimeters overall, with a 610-millimeter five-star base diameter, 540 millimeters of clear width between the armrests, a 90-millimeter finished seat cushion, and 70-millimeter backrest padding. Its construction pairs a molded polymer seat shell with a steel tilt mechanism. The base is produced in black molded nylon or glass-filled nylon, and the chair uses a Class 4 chrome gas lift, twin-wheel casters, 45 kilogram per cubic meter seat foam, and mesh rated for a 25 kilogram lateral support load. The recommended user weight capacity is 120 kilograms, and net weight is 12.5 kilograms. Everyday operation is centered on straightforward task-chair functions. A pneumatic lever adjusts seat height through a 100-millimeter stroke, with a maximum seat height of 540 millimeters. The center-tilt mechanism allows the backrest to recline to 12 degrees and return under body weight, while a rear rotary knob adjusts recline resistance. The seat rotates 360 degrees, and five 50-millimeter twin-wheel casters support rolling movement on hard floors. This model is appropriate for individual office workstations where a compact 610-millimeter-wide task chair is required. It is also suitable for conference rooms, home offices, and study desks that benefit from swivel access and basic recline. Procurement planning should account for fixed arm height and width, black-only styling, hard-floor caster use, assembly time, and packaging supplied as one set across two cartons with a packaged gross weight of 23 kilograms.
