The unbranded EMOC-HB625-FA ergonomic mesh office chair features a sleek, professional all-black finish that complements modern commercial and residential work environments. Its high-back silhouette integrates a curved, neck-supporting adjustable headrest, fixed closed-loop armrests, and a sturdy five-star base, delivering a balanced, streamlined visual presence without protruding or overly decorative elements. The chair measures 625 x 660 x 1240 mm overall, with seat dimensions of 490 mm width and 470 mm depth, armrests positioned 190 mm above the seat surface, and a 580 mm tall backrest tailored to support the full length of the spine. Durable, purpose-built materials form the core of the chair’s construction. The backrest uses a reinforced nylon-fiberglass frame strung with tensioned breathable mesh, with an integrated molded PP contoured dual-lobe lumbar support built directly into the frame to align with the natural lower back curve. The seat holds a 50 mm thick core of 45D high-density molded polyurethane foam, upholstered in woven black polyester fabric for soft, resilient seating. Fixed armrests are formed as one-piece black PP units connected between the seat and back frame for stable upper body support. The glass-fiber reinforced black nylon five-star base supports a Class 3 black powder-coated steel gas lift, fitted with 50mm black PU dual-wheel swivel casters. The headrest uses a 30D soft foam pad wrapped in black fabric, curved to cradle the neck. The mesh back holds an abrasion resistance rating of 50000 double rubs, the gas lift is rated for 100000 height adjustment cycles, the five-star base carries a 1000 kg static load rating, and the chair supports a maximum user weight of 136 kg, with a net weight of 16 kg. Core functional features support varied work styles: pneumatic seat height adjustment delivers 100 mm of vertical travel via an under-seat lever, locking at the user’s preferred position within the 415 mm to 515 mm floor-to-seat range. The chair offers full 360-degree swivel rotation for multi-directional access to desk materials, plus a lockable backrest recline that tilts up to 126 degrees from upright, with adjustable tension control and a dedicated lock for the fully upright position for focused task work. The headrest adjusts 100 mm vertically to match varying user neck heights, and the dual-wheel PU casters roll smoothly across hard floors and low-pile carpet for easy repositioning. This chair is suited for a wide range of work settings, including open office workstations, where its ergonomic support structure accommodates 8 hours of daily task work; home office spaces, where its compact 625 mm width fits standard desk setups with ample seated knee clearance; conference and meeting rooms, where swivel and recline functions support collaborative discussion; administrative and staff work areas, where fixed armrests deliver consistent support for regular desk tasks; and commercial co-working spaces, where its durable mesh and foam construction withstands high-frequency multi-user use. It pairs well with a 2.4 m executive desk for a cohesive, professional setup.
