The Mid-Back Ergonomic Mesh Swivel Office Task Chair with Fixed Armrests, model MB-FA-MESH-670, is an unbranded ergonomic mesh office chair designed for versatile workplace and home use. Its visual form balances understated professional styling with functional structure: a gently curved mid-back mesh panel paired with a neatly padded rectangular seat, supported by a sleek five-star base and streamlined T-shaped fixed armrests, creating a compact, polished silhouette that integrates seamlessly into formal and casual work environments without unnecessary ornamentation. Constructed for balanced durability and seated comfort, the chair features a breathable woven polyester mesh backrest set in a glass-fiber reinforced polypropylene frame, paired with a seat upholstered in woven polyester fabric over high-density molded polyurethane foam. The fixed T-armrests are made from injection-molded polypropylene, while the base uses reinforced nylon composite fitted with 60mm diameter nylon twin-wheel casters. Core functional components include a carbon steel Class 4 gas lift, a 2.5mm thick steel butterfly plate tilt mechanism, and abrasion-resistant mesh rated for 50000 Martindale cycles, with casters tested for 100000 rolling cycles for consistent long-term use. The chair weighs 11 kg, with a maximum recommended static load of 200 kg, and supports users up to 1850 mm tall. Practical functions are tailored to common work routines: a side-activated lever enables 100mm of vertical seat height adjustment to a maximum seat height of 520 mm, full 360-degree swivel supports easy reach across adjacent work surfaces, and a 135-degree maximum back tilt with adjustable tension lets users shift between focused and relaxed postures, with a single-position upright lock for concentrated task work. The contoured mesh panel delivers built-in lumbar support aligned to the lower back, fixed armrests sit 180 mm above the seat to hold forearms comfortably during typing or discussion, and twin-wheel casters roll smoothly across hard floors and low-pile carpet. This chair is suited for open office workstations, compact home office study spaces, conference rooms, and reconfigurable training room setups, and pairs appropriately with a 2.4 m executive desk. For procurement, note that each unit ships in two cartons, requires 40 minutes of assembly per set, carries a packaged gross weight of 23 kg per set, and allows 135 sets to be loaded in a 20GP container at 85% space utilization, with no custom branding or modified configuration options available at the base offering level.
