Product Description

The ERC-MESH-HB-01 is an unbranded high-back ergonomic office chair designed for focused desk work in commercial settings. Its black finish gives it a neutral appearance suited to a broad range of interiors, while the tall mesh back, integrated headrest, and five-star base create a functional executive-style silhouette. Visually, the chair pairs a black flexible woven mesh back with a contoured polymer outer frame. The same mesh language continues into the curved headrest, which is mounted on a height bracket. The seat is upholstered in black woven fabric over a molded cushion, with visible edge stitching and a rounded waterfall front. Rigid black polymer arm posts and padded polymer top pads complement the frame, while the painted metal and nylon five-star base, gas lift, and twin-wheel casters complete the mobile swivel layout. Construction balances comfort and support. The seat uses 80 mm molded polyurethane foam on a 12 mm molded plywood or polymer carrier connected to a steel mechanism plate. The finished seat cushion thickness is 90 mm, and the backrest padding thickness is 70 mm. A 240 mm lumbar support zone is integrated into the high-back design. Overall dimensions are 670 by 670 by 1290 mm, with 540 mm of clear width between the armrests. The chair has a net weight of 17.5 kg and a recommended user weight capacity of 150 kg. Adjustability is centered on extended workstation comfort. A pneumatic lever provides 90 mm of seat-height travel, from 450 mm to 540 mm. The synchronized seat-and-back tilt reclines to 125 degrees and offers selectable locked positions. A rear rotary knob controls tilt tension across a five-turn setting range. Height-adjustable arm pads move through 70 mm vertically, from 230 mm to 300 mm above the seat. The headrest bracket adds further upper-back and head support for users up to the recommended maximum height of 190 cm. This model is appropriate for individual office workstations, hot desks, administrative areas, and shared staff workspaces where swivel movement, rolling access, recline control, and lumbar support are required. The twin-wheel casters have a rolling durability target of 100,000 cycles. For procurement and installation planning, each set ships in two cartons with a packaged gross weight of 23 kg and a carton volume of 0.26 cubic meters. Reference assembly time is 40 minutes per set. A 20GP container can accommodate 135 sets at 85 percent space utilization. Buyers should confirm delivery terms, assembly responsibilities, replacement parts, and quantity-based logistics before ordering.
