The High-Back Grey Mesh Ergonomic Office Chair (model EOCH-GM605-FA, unbranded) presents a streamlined, professional silhouette anchored by a smooth grey finish that complements contemporary interior palettes. Its open, proportional layout centers on a tall mesh back aligned with a generously sized seat, supported by a symmetrical five-star base that delivers stable visual balance without bulky protrusions. Fixed, gently curved matte armrests sit at a consistent height relative to the seat, while the elevated adjustable headrest extends the backrest’s vertical line to create a cohesive, uncluttered form suitable for mixed work environments. Built for sustained daily use, the chair combines durable, purpose-selected materials: a tensioned breathable polyester mesh back supported by a 1.5 mm thick steel internal frame, paired with a 70 mm thick high-density polyurethane foam seat (45 kg/m³ density, 65% rebound) set atop a 14 mm bent plywood support board. The glass-fiber reinforced nylon five-star base holds 60 mm diameter polyurethane twin-wheel casters, connected to a 50 mm outer diameter pneumatic steel gas lift. The integrated headrest uses a matching breathable mesh panel on a polypropylene support frame, with fixed curved polypropylene armrests that resist scuffs from regular contact. Functional features are tailored to flexible work needs: lever-operated pneumatic seat height adjustment delivers 100 mm of vertical travel, with a maximum seat height of 530 mm, while 360-degree swivel enables easy reach across adjacent work surfaces. The back reclines to a 135 degree maximum tilt, with a 125 degree position and three additional suggested lock settings to support upright task work or relaxed postures, paired with a fixed contoured mesh lumbar zone for consistent lower back support. The headrest adjusts 100 mm vertically and tilts 40 degrees to align with varying neck positions, and the dual-wheel casters roll smoothly across both hard and soft floor surfaces. The chair supports a maximum recommended user load of 150 kg, with a static load rating of 1120 kg for the five-star base and caster durability rated for 40000 rolling cycles. This chair is suited for home office workspaces serving remote workers and students during 8 hours of daily desk work, open-plan corporate office workstations paired with standard 760 mm height desks, small meeting and conference rooms for short to medium duration gatherings, and home study rooms where its neutral grey tone coordinates with light-toned modern furniture. It pairs well with 2.4 m executive desks for cohesive workspace setups. Procurement teams should note each unit ships across two cartons, with a packaged gross weight of 23 kg per set and total carton volume of 0.26 m³; 135 sets fit in a 20GP container at 85% space utilization. Assembly requires an 40 minutes per unit, and specifiers should confirm ergonomic alignment for specific daily use cases prior to bulk purchase.
