Product Description

The UEC-HBM-01 is an unbranded high-back ergonomic office chair designed for desk-based work where back support, adjustable posture, and easy movement are priorities. Its black finish and neutral profile give it a practical appearance for modern office interiors, while the tall back, integrated headrest, contoured frame, and flat arm pads create a structured seating silhouette suited to both dedicated workstations and shared workspaces. The chair has an overall footprint of 670 by 670 mm and an overall height of 1280 mm, with 540 mm of clear width between the armrests. Visual depth comes from the flexible woven mesh back, molded seat, layered headrest, and five-star caster base. Its layout places the padded headrest above the high back, a defined lumbar support zone through the lower back, and adjustable armrests alongside the seat for a balanced, task-oriented form. Construction combines a black mesh tension surface with a glass-fiber-reinforced polymer outer back frame shaped around the shoulder and waist areas. The seat uses molded high-resilience polyurethane foam with black woven-fabric upholstery, a 90 mm finished cushion thickness, and 45 kg/m3 foam density. Backrest padding is 70 mm thick, and the lumbar support zone is 240 mm high. The headrest uses a black polymer support shell with a padded cushion faced in either synthetic leather or fabric. Armrests are built from injection-molded black polymer supports with soft-touch pads. Beneath the seat are a steel tilt mechanism, chrome-finished steel gas piston, black telescopic sleeve, nylon base, and twin-wheel casters. The chair weighs 18.5 kg and is rated for a recommended user weight of 150 kg. Functional adjustment is centered on daily task-chair use. A pneumatic lever controls seat height through a 90 mm stroke using a 50 mm class-4 gas lift. The synchro-tilt mechanism allows the seat and back to move together, reclines to 18 degrees, and locks in three positions. A side rotary knob adjusts backward recline resistance, while the central gas-lift bearing and radial caster base provide 360-degree swivel movement. These features support posture changes during long computer tasks, conversation, or short reclined breaks without leaving the workstation. The model is appropriate for individual office desks, conference rooms, shared desks, and home offices. Its black, understated appearance works well where a single chair type must coordinate with existing work surfaces and storage. Residential buyers selecting it for a home office should consider the high-back profile and headrest height, while commercial buyers should evaluate quantity planning, movement across flooring, replacement needs, and whether the armrest width and seat form suit the intended user group. Procurement teams should also note that each set ships in two cartons, with packaged gross weight of 23 kg and reference assembly time of 40 minutes.
