The Ergonomic High-Back Mesh Office Chair with Adjustable Headrest, model EOCH-MESH-660, is an unbranded task seating solution built for balanced support and versatile placement across work and study environments. Its visual profile features a streamlined high-back form anchored by a wide nylon five-star base, with a breathable mesh backrest, fixed curved matte armrests, and a curved padded headrest that sits atop the back frame to follow the natural line of the upper spine. The chair’s compact layout fits seamlessly beneath standard height desks without excess overhang, creating a polished, unobtrusive look suitable for both professional and residential interiors. Construction centers on durable, purpose-selected materials: the backrest uses tensioned slatted polyester mesh set in a reinforced polypropylene frame with fiberglass additive, with an integrated contoured lumbar zone formed directly into the frame structure. The seat features a core of molded high-density polyurethane foam wrapped in woven polyester fabric, paired with a Class 3 black steel gas lift, 60mm diameter mute PU swivel casters, and fixed curved polypropylene armrests with a smooth matte finish. Material performance metrics validate long-term use, including rated mesh abrasion resistance, gas lift and tilt mechanism cycle durability, and a five-star base static load rating aligned with daily use requirements. Core functional features support customized comfort for extended seating: a side-lever operated gas lift adjusts seat height across its full vertical travel, while the padded headrest offers dedicated vertical adjustability to align with different user heights. The backrest reclines to a 125° maximum angle with lockable positions, paired with a tension control knob to adjust recline resistance to match user weight. The chair delivers 360-degree swivel rotation and smooth rolling mobility across both hard and soft floor surfaces, with an integrated lumbar zone that maintains consistent lower back support without separate adjustment parts. This model is well suited for a wide range of spaces: it works at open plan office workstations with standard desk heights for daily task work, fits compact home office layouts, provides appropriate support for two-hour conference room meetings and collaborative sessions, serves as adjustable shared seating in cubicle environments, withstands eight hours of daily use in administrative staff work areas, and maintains comfort during long study sessions in student spaces. Procurement teams should note that each unit ships across two cartons, with a stated reference assembly time per set, packaged gross weight, and carton volume that supports predictable shipping planning; 135 sets can be loaded into a 20GP container at 85% space utilization for bulk orders. The chair supports a maximum recommended user weight of 150 kg, and its fixed armrest design should be evaluated against workspace requirements that may call for adjustable arm support, while its 15 kg net weight enables easy repositioning within dynamic work environments.
