Product Description

This high-back ergonomic mesh office chair, model EMOC-HB-AL001, delivers a balanced blend of structured support, breathable comfort, and flexible functionality for daily seated work, with an unbranded design that fits seamlessly across a wide range of professional and personal work environments. Its overall dimensions measure 650 x 700 x 1210 mm, with a tall 580 mm backrest topped by a compact 60 mm adjustable headrest, a 505 mm wide upper back, and a polished die-cast aluminum alloy 5-star base that creates a stable, streamlined visual profile free of overly bulky detailing. The contoured form follows natural spinal curvature, with integrated lumbar support positioned to align with the lower back without protruding awkwardly, and soft polyurethane arm pads that sit at a fixed 270 mm height above the seat surface at their base setting for unobtrusive, clean line of sight across workspaces.
Construction uses durable, purpose-built materials selected for long-term regular use: the backrest is upholstered in breathable polyester mesh to promote consistent air circulation, while the 120 mm thick seat cushion uses 55 kg/m³ high-density molded polyurethane foam with a 60% rebound rate, set within a reinforced PP shell with fiber backing. Frame components combine powder-coated steel and reinforced nylon for structural rigidity, with a chrome-finished steel gas lift cylinder, dual-wheel polyurethane casters, and uniform seam stitching at 8 stitches per 30 mm to prevent premature fabric wear. The chair supports a maximum user weight of 181 kg, with gas lift durability rated for 120000 cycles and caster rolling durability rated for 100000 cycles, backed by a 5-year warranty.
Core functional features support customized comfort for extended use: pneumatic seat height adjustment offers 100 mm of total travel, the backrest tilts to a 45 degree maximum angle with multi-position lock, armrests adjust 100 mm vertically, the headrest shifts vertically and rotates 45 degrees to suit different neck positions, the height-adjustable contoured lumbar support moves to match individual spinal alignment, and 360 degree swivel paired with smooth-rolling casters allows easy movement across both hard and soft floor surfaces. The chair is well suited for corporate office workstations supporting 8+ hour daily desk work, home office setups pairing with standard desk heights, executive private offices for managerial staff, conference rooms for collaborative meetings, and co-working spaces serving rotating users, with a recommended match for 2.4 m executive desks.
For procurement planning, each unit ships across 2 cartons with a total packed gross weight of 18 kg and total packed volume of 0.42 CBM, requiring 40 minutes of assembly time per set. Buyers should account for the chair’s full footprint when planning workspace layouts, and confirm that adjustable height ranges align with existing desk setups for intended users.
