Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest and Adjustable Arms, model EMB-HB-01, is an unbranded task chair designed for focused workstation use. Its visual character is defined by a black flexible mesh back set within a curved black polymer frame, paired with a dark gray woven fabric seat cushion. The high-back form includes a headrest, matte black polymer lumbar component visible through the mesh, and fixed black polymer arm pads on molded support posts. A black painted five-star base and twin-wheel casters complete the streamlined commercial seating profile, with a clear width of 540 mm between the armrests. Construction balances breathable support with structured load handling. The backrest uses flexible mesh stretched over the curved frame and incorporates a 240 mm high lumbar support zone with 70 mm of backrest padding. The seat combines dark gray woven fabric over molded foam and a polymer seat shell, with a finished cushion thickness of 90 mm. Inside, the chair uses a 25 mm steel tube back-support frame and a 3 mm steel seat plate. Height adjustment is delivered through a metal Class 4 gas lift, while the base is specified as a black painted nylon-composite or steel radial structure fitted with nylon twin-wheel casters. For daily use, the chair offers pneumatic seat-height adjustment with 100 mm of travel, covering seat heights from 440 mm to 540 mm. A synchronized tilt mechanism allows the back to recline to 118 degrees and lock in the upright position. The gas-lift bearing and five-star caster base provide 360-degree swivel movement, and the five twin-wheel casters support multi-directional movement across hard floors and low-pile carpet. The recommended user weight is 136 kg, and the chair has a net weight of 18.5 kg. This model is appropriate for individual office workstations used six to eight hours daily, as well as meeting rooms, home offices, and study desks where adjustable height, lumbar support, swivel access, and mobile seating are required. Its restrained black and dark gray finish also makes it suitable for interiors that prefer a neutral, professional appearance without a prominent brand mark. Procurement planning should account for one set supplied in two cartons, packaged gross weight of 23 kg per set, and a reference assembly time of 40 minutes per set. Buyers should also note the fixed armrest configuration, select the base material based on project requirements, and confirm floor type before standardizing the casters across an installation.
