The EOCH-MESH-650GR is an unbranded high-back ergonomic office chair designed for balanced comfort and flexible use across work and study settings. Presented in a neutral grey finish, the chair features a streamlined, contoured profile, with a tall mesh backrest rising to an adjustable curved headrest, paired with softly padded 3D armrests and a polished five-star base. Its compact 650mm width allows it to fit neatly into tight layout configurations without appearing bulky, while the mesh back and padded seat create a cohesive, professional visual suited to contemporary interiors. The chair’s structure uses durable, purpose-built materials: the backrest is upholstered in high-elastic breathable woven polyester mesh set within a glass-fiber reinforced nylon frame, paired with a molded high-resilience polyurethane foam seat supported by an internal plywood board. The base is polished chrome-plated steel, fitted with PU-tread casters with nylon hubs, connected via a chrome-plated steel Class 4 gas lift. Armrests feature soft PU padding on sturdy nylon adjustment brackets, and the headrest uses matching breathable mesh over a curved nylon frame. Designed for extended seated use, the chair delivers targeted adjustability to suit varied user preferences: pneumatic seat height adjustment operates via a right-side lever, locking at any chosen position, while the backrest reclines to 135 degrees with three lock positions and adjustable tension control aligned to user weight. The 3D armrests adjust for height, fore-aft slide, and inward-outward rotation, and the headrest adjusts for both height and tilt to cradle the neck. A fixed contoured lumbar zone built into the mesh back delivers mid-back pressure relief, while full 360-degree swivel and smooth-rolling casters support easy movement across hard floors and low-pile carpet. This chair suits a wide range of spaces, including home office workstations for daily full-shift use, corporate open plan offices, conference rooms for extended collaborative meetings, home study areas for teen and adult users, and compact startup office fit-outs where dense workstation layouts are common. It also pairs effectively with height-adjustable sit-stand desks. For procurement teams, the chair ships as one set across two cartons, with a noted assembly time of 40 minutes per unit, and optimized dimensions to support efficient bulk container loading, with sufficient weight capacity to accommodate a broad range of users. Buyers should note the product arrives unassembled, and plan for appropriate on-site assembly support when ordering for large-scale fit-outs.
