The YUXIANG EMC-670ADJ Mesh Task Chair is a high-back ergonomic seating solution engineered to balance comfort, durability, and functional flexibility for daily use. Its streamlined profile features a 570 mm tall contoured backrest paired with a 315 mm wide adjustable headrest, supported by a polished nylon-reinforced polymer five-star base for a clean, professional aesthetic suited to modern work environments. All adjustment controls are positioned for intuitive access, with the contoured lumbar pad integrated directly into the back mesh to deliver consistent lower back support without protruding hardware that disrupts the chair’s sleek form. Built for long-term commercial and residential use, the chair’s backrest and headrest are upholstered in breathable woven polyester-nylon blend mesh, rated for 30000 Martindale abrasion cycles to resist wear from regular use. The seat cushion uses molded high-resilience polyurethane foam with a density of 65 kg/m³ and 40% rebound rate, mounted on a 12 mm thick molded plywood support board for stable weight distribution. Structural components include reinforced glass-fiber nylon polymer back frames and armrest supports, a chrome-plated precision steel tube gas lift, a 3 mm thick stamped steel tilt mechanism plate, and dual-wheel polyurethane casters designed to roll smoothly across both hard flooring and carpet. Key performance ratings include a 150 kg recommended static user load capacity, 1360 kg five-star base static load rating, 120000 cycles of caster rolling durability, and 120000 tilt cycles for the recline mechanism. Functional features are tailored to support varied working postures: pneumatic seat height adjustment delivers 85 mm of vertical travel to a maximum floor-to-seat height of 530 mm, the headrest offers 60 mm of height adjustment plus pivot tilt, and armrests adjust 80 mm vertically to match desk and user height. The synchronous tilt mechanism allows a 120° maximum recline with lock functionality, while 360° swivel and smooth-rolling casters enable easy repositioning. The chair suits private offices for full-time staff requiring 8+ hours of seating support, open-plan workstations for quick movement between adjacent work points, home offices for shared use across different household members, conference rooms for extended meeting comfort, desk-based IT and task work settings to reduce posture-related strain, and high-traffic co-working spaces where multi-user durability is critical. For procurement planning, each unit ships in 2 cartons with a total packaged gross weight of 23 kg, requires 40 minutes of assembly per set, and 135 sets fit a 20GP container at 85% space utilization, supporting efficient bulk ordering for commercial fit-outs.
