Product Description

The ERC-MESH-HB-01 is an unbranded high-back ergonomic office chair designed for users seeking structured support, breathable contact surfaces, and adjustable posture control in a professional task chair. Its appearance combines a black flexible woven mesh back with a charcoal woven-fabric seat, black polymer armrests and frame components, and a black five-star base. The contoured backrest rises to a padded headrest, while the integrated curved elastic mesh lumbar zone creates a defined support area in the lower back. The layout follows a conventional swivel task-chair form, with dual-wheel casters beneath the five-star base and side controls positioned under the seat. The backrest uses black flexible woven mesh stretched over a contoured polymer outer frame, balancing visual lightness with a supportive seating surface. The seat combines charcoal woven fabric over molded polyurethane foam, with a finished cushion thickness of 90 mm and foam density specified at 45 kg/m3. The backrest padding thickness is 70 mm, and the lumbar support zone height is 240 mm. Armrests are made from rigid black polymer supports with soft-touch polymer pads, with 540 mm clear width between them. The mechanism uses a black stamped-steel tilt assembly with a polymer cover, paired with a chrome-plated steel telescopic gas lift and black polymer shroud. The recommended user weight capacity is 150 kg, and the chair net weight reference is 18 kg. Functional adjustment is centered on extended seated comfort. A right-hand under-seat lever operates the pneumatic seat-height lift, which has a 90 mm stroke. The synchronized seat-and-back tilt offers an 18-degree recline with multi-position lock, while a rear rotary knob changes back tension to suit the user’s body weight. The padded headrest adjusts through 90 mm vertically and pivots 25 degrees, adding neck support for high-back seating. The swivel base and dual-wheel casters support movement between desk zones, and the product is rated for 100,000 gas-lift height cycles, 100,000 caster rolling cycles, a 1,200 N back mesh tensile rating, and a 950 N seat-slide static load test target. This chair is suitable for private office workstations, open-plan professional environments, home offices, and meeting-focused task areas where a rolling high-back chair is needed. It is intended for standard 760 mm office desks and supports an 8-hour desk-work setup through its lumbar mesh, headrest, tilt control, and adjustable seat height. Procurement planning should account for delivery as one set in two cartons, with a packaged gross weight of 23 kg per set and carton dimensions of 850 by 420 by 720 mm. The reference carton volume is 0.26 cubic meters per set, the indicative loading for a 20GP container is 135 sets at 85 percent space utilization, and the reference assembly time is 40 minutes per set. Buyers should also confirm site flooring, assembly resources, and desk compatibility before installation.
