Product Description

The ERC-MESH-HB-GN-01 is an unbranded high-back ergonomic executive chair designed for workstations that call for structured support, adjustable seating, and a polished professional appearance. Its tall grey mesh backrest follows a contoured silver metal frame, creating an open visual profile while supporting full-back contact. The green woven-fabric seat cushion contrasts with the grey mesh, while the curved mesh-faced headrest, black polyurethane arm pads, silver frame, and polished aluminum five-star base complete the executive styling. Dual-wheel casters keep the chair mobile across typical office settings. With overall dimensions of 680 x 680 x 1260 mm, the chair provides a 540 mm clear width between armrests, a 90 mm finished cushion thickness, 70 mm of backrest padding, and a 240 mm lumbar support zone. Construction combines a grey flexible mesh back, green upholstered cushion, load-bearing seat shell, silver painted metal structure, polished aluminum-alloy base, and black arm-contact surfaces. The specified internal build uses a 3.0 mm steel plate and an 18 mm molded polymer seat shell. The cushion is formed with an 80 mm molded foam core under green woven fabric. A 50 mm class-4 gas lift connects the seat to the five-star base, and the dual-wheel caster arrangement supports swivel movement. Functional adjustment is centered on extended comfort during desk work. A side lever controls pneumatic seat-height movement through a 90 mm stroke. The synchro-tilt mechanism allows the back to recline from 93 to 120 degrees, using a seat-to-back ratio intended to maintain continuous lumbar contact. Users can select from three tilt-lock positions and turn the rear tension knob to match recline resistance to body weight. The arms move through 70 mm of vertical adjustment and use soft polyurethane pads for forearm support. The chair is suited to executive offices, managerial workstations, professional private offices, open-plan work areas, meeting rooms, and home offices. It is intended for users from 1600 to 1900 mm tall, with a recommended user weight capacity of 150 kg. Procurement planning should account for delivery as one set packed in two cartons, with a packaged gross weight of 23 kg per set, reference carton volume of 0.26 cubic meters per set, and a reference assembly time of 40 minutes per set. The headrest housing may be supplied in black or grey molded support housing, so buyers should confirm finish consistency when coordinating a fleet of chairs.
