The Mid-back Ergonomic Mesh Office Task Chair with Fixed Armrests, model MESH-TASK-620, is an unbranded professional seating solution designed for consistent daily use across commercial and residential workspaces. Its streamlined, professional silhouette features a contoured mid-back profile paired with fixed curved loop armrests, creating a neat, unobtrusive visual presence that aligns with a range of modern interior aesthetics without bulky protruding elements. The all-black finish across frame, base, casters and seat upholstery delivers a cohesive, neutral look that blends seamlessly with varied furniture palettes. Constructed for long-term durability, the chair uses a reinforced polypropylene plastic frame and armrest structure, paired with a breathable polyester mesh backrest that incorporates a fixed S-curve integrated lumbar support zone. The seat features a 90mm thick cushion built from high-density molded polyurethane foam with 35 kg/m³ density, upholstered in black woven fabric, supported internally by 12mm multi-layer plywood. The base is formed from black reinforced nylon in a five-star configuration, fitted with black polyurethane dual-wheel casters, while height adjustment relies on a powder-coated steel mechanism and chrome-plated steel gas lift. The mesh back delivers 50,000 double rubs of abrasion resistance, casters support 40,000 rolling cycles, and the chair carries a 136kg recommended static load capacity with a 17kg net weight per unit. Core functional features include pneumatic lever-operated height adjustment with 100mm vertical travel, 360-degree full swivel on the central spindle, 12-degree synchro-tilt with single-position lock, and under-seat knob adjustment for tilt tension resistance. The 540mm clear width between armrests accommodates a broad range of user sizes, while five dual-wheel casters enable smooth omnidirectional movement across flooring. This chair is well suited for open office workstations, where its mid-back profile supports 8 hours of daily seated work for staff; compact dimensions make it an ideal fit for home office desks paired with standard work surfaces. Its sleek design coordinates with modern conference room furniture, while its durable build stands up to frequent multi-user turnover in training rooms, and its neutral professional appearance works for reception visitor seating. It also delivers cost-effective, long-lasting seating for small business, startup and SME workspace layouts. Procurement teams should note each unit ships across two cartons, with 40 minutes of assembly required per set.

Overall assembled dimensions measure 620 x 640 x 1060 mm, to support precise space layout planning prior to installation.
