The Gray High-Back Ergonomic Mesh Office Chair, model EMOC-GR-510FH, features a streamlined, professional profile finished in neutral gray that complements a wide range of interior design palettes. Its layout balances structured support with a compact footprint, with a contoured high back, adjustable headrest, fixed integrated padded armrests, and a five-prong base with evenly spaced casters for stable, balanced positioning. The chair’s construction uses durable, performance-focused materials selected for long-term regular use. The backrest uses breathable woven mesh stretched over a reinforced nylon PA+GF frame, with an integrated contoured lumbar zone molded directly into the frame structure for consistent lower back support. The seat pairs a high-density molded polyurethane foam core with a breathable mesh fabric upholstery surface, while the headrest is a curved, mesh-covered foam pad. The frame, fixed loop armrest structure, and glass-fiber reinforced five-star base use tough nylon formulations, with the base featuring a 2.5mm wall thickness for structural rigidity. A Class 3 black steel gas lift with 50mm tube diameter connects the seat to the base, paired with a 3mm steel plate under-seat mechanism for control functions, and 60mm dual-wheel PU soft casters for floor contact. Designed for extended seated use, the chair delivers a suite of user-centric adjustability functions. Pneumatic seat height adjustment operates via an under-seat lever, with 100mm of total travel and a maximum seat height of 510mm. The synchronized back tilt includes tension adjustment and a maximum 15° recline angle, with a tilt lock to hold the chair in an upright position for focused task work. The chair supports 360° swivel around its central axis, while the headrest offers both vertical height and angle adjustment via its side mounting bracket. The casters roll smoothly across hard floors and low-pile carpet, supporting easy repositioning. This chair is well suited for a range of commercial and residential spaces. It fits standard 760mm desk heights to support full workday seated use at corporate open office workstations and dedicated employee task seating, where its adjustable features accommodate a broad range of user body types. Its compact 680mm depth footprint fits small home work areas, making it a strong choice for home offices and study spaces. The neutral gray finish and smooth swivel function make it appropriate for conference and meeting room seating, while its durable mesh construction and reliable casters stand up to the frequent multi-user turnover of shared co-working spaces. It pairs effectively with 2.4m executive desks for private office setups. For procurement planning, note that each chair ships across two cartons, with a reference assembly time of 40 minutes per unit. It holds a recommended user weight capacity of 136kg, with material performance ratings suited to high-frequency daily use. The unbranded design allows for flexible integration across different facility furnishing schemes without conflicting with existing brand standards, and its modular component construction supports straightforward long-term maintenance.
