The model ERG-MSH-625-GRY ergonomic office chair comes in a neutral grey finish with a contoured high-back silhouette, balanced dimensions that fit standard workstation footprints without excess bulk, and a streamlined profile that blends into professional and residential spaces alike. Its construction pairs a breathable polyester mesh back supported by a glass-fiber reinforced polypropylene frame, with a molded high-density polyurethane foam seat resting on a 12 mm thick plywood support board. The frame connects to a reinforced nylon five-star base fitted with smooth-rolling PU casters, anchored by a black powder-coated Class 3 steel gas lift and 2.5 mm thick steel butterfly tilt plate. A fabric-wrapped molded foam fixed curved headrest sits atop the backrest, matched with integrated fixed loop polypropylene armrests that sit at a consistent height for stable forearm support, and a contoured mesh section that delivers built-in targeted lower back support without separate adjustment controls. Core functional features support extended seated comfort: full 360-degree swivel rotation enables easy reach across adjacent work surfaces, while 100 mm of vertical seat height travel adjusts via a convenient side lever to align with individual user positioning. The lockable butterfly tilt mechanism offers three secure recline positions with a maximum 15-degree recline angle, paired with an under-seat knob that lets users adjust tilt tension to match their weight for consistent, controlled movement. The 35 kg/m³ seat foam offers a 45% rebound rate, and the mesh back delivers consistent airflow to reduce heat buildup during 8 hours of daily desk use, with a mesh abrasion rating of 50000 Martindale cycles. The chair supports a recommended user weight of 136 kg, with a maximum static load capacity of 159 kg and a gas lift rated for 120000 cycles, and accommodates users up to 185 cm tall. This chair suits open-plan office workstations, home office spaces, conference rooms, and standard cubicle workstations, pairing seamlessly with fixed-height or height-adjustable desks at the standard 760 mm work surface height; its 625 mm width fits standard 800 mm cubicle openings, and its rolling casters work smoothly on hard residential flooring. For procurement planning, each chair ships in 2 cartons, requires 40 minutes of assembly per unit, and holds a packaged gross weight of 23 kg with a total carton volume of 0.26 m³, supporting 135 sets per 20GP container at 85% space utilization. As an unbranded product, it delivers reliable core ergonomic features without premium branding costs, with fixed armrest and support components that reduce long-term maintenance points in high-traffic work environments.
