Product Description

The ERG-HBM-01 is an unbranded high-back ergonomic task chair designed for regular office and home-workstation use. Its appearance is understated and functional, with a black mesh back and matching mesh headrest, a black fabric seat, black polymer framing, fixed T-shaped armrests, and a five-star nylon base. The tall back creates a structured silhouette, while the curved headrest and layered padding give the chair a supportive, task-oriented profile. The overall footprint is 650 by 650 by 1250 mm, with a 540 mm clear width between the armrests. Construction combines cushioned support with a molded internal structure. The seat uses black woven fabric over an 80 mm molded polyurethane foam cushion and features a rounded waterfall front; the stated finished cushion thickness is 90 mm. The backrest uses tensioned black polyester mesh within a black polymer outer frame, with 70 mm of backrest padding and a 240 mm lumbar support zone. The inner seat and back structure includes a 12 mm glass-fiber-reinforced polypropylene shell with steel reinforcement plates. The headrest pairs a curved mesh center panel with black polymer side padding, while the fixed armrests are injection-molded nylon with soft-touch polyurethane pads. A gas-lift steel spindle connects the seat to the nylon five-star base, which is fitted with twin-wheel casters. The chair provides practical adjustment for seated work without adding complex armrest controls. A right-hand pneumatic lever adjusts seat height through a 100 mm stroke, from 450 to 550 mm. The synchronized recline allows the backrest to move 18 degrees from upright with linked seat-to-back movement and a single-position lock. A rotating tension knob controls recline resistance, and the headrest offers 80 mm of height travel plus a 15-degree angle tilt. The fixed T-armrests keep the layout simple and maintain clear lateral space. This model is suited to open-plan offices, private workstations, meeting rooms, shared desks, and adult home-office use, including users up to 190 cm tall and a recommended user weight of 135 kg. It is intended for hard floors or low-pile carpets. Procurement teams should plan for assembly, with a reference time of 40 minutes per set, and note that the product ships as one set across two cartons. The chair weighs 16 kg net, while packaged reference details show 23 kg per set and a carton volume of 0.26 cubic meters. Buyers should also confirm that fixed armrests, black upholstery, swivel mobility, and the listed adjustment range match the intended workstation and user requirements.
