Product Description

The Mesh High-Back Ergonomic Office Chair, model ERG-MESH-HB-01, presents a modern task-chair profile defined by a dark-gray mesh back and matching headrest, a dark upholstered foam seat, and a light-gray molded polymer frame. Its high-back form extends support from the lumbar region through the upper body, while the integrated headrest creates a continuous visual line above the backrest. Fixed-width padded armrests sit within a 540 mm clear arm span, and the nylon five-star base gives the chair a balanced commercial-office footprint. The overall dimensions are 650 x 650 x 1290 mm, including the elevated headrest. Breathable dark-gray woven mesh is tensioned over a framed polymer back structure, helping the backrest retain a light, open appearance. The seat uses dark fabric-facing over molded polyurethane foam and a polymer load-bearing shell. Its finished cushion is 90 mm thick, with a 70 mm molded foam comfort layer specified at a 45 kg/m3 density target and 40% rebound target. The backrest includes 70 mm of padding, while a separate curved lumbar carrier occupies a 240 mm support zone. Light-gray molded polymer forms the frame, side supports, lumbar carrier, armrest posts, and arm-cap structure, with a chrome-plated steel gas lift, light-gray nylon five-star base, black telescopic trim, and twin-wheel casters completing the construction. Functionality is centered on adjustability and movement. A right-side lever controls the pneumatic seat-height lift, which has a 90 mm public lift value, and the seat rotates through 360 degrees. The synchro-style tilt mechanism coordinates seat and back movement, with a 125-degree maximum back angle. The lumbar carrier follows the lower back and is adjusted by a side knob for depth or tension. Each armrest uses a visible side release button for height adjustment, with 80 mm of adjustment travel. Casters provide mobility across desk, meeting, and home-office settings. The chair is suited to individual desks and open-plan workstations where ventilation, lumbar support, swivel access, and full-day task support are priorities. It is also appropriate for conference rooms, manager offices, and home offices used for long meetings or computer work. Its recommended user weight capacity is 150 kg, and the suggested user height range reaches 190 cm. Durability targets include 100,000 caster rolling cycles, 100,000 gas-lift height-adjustment cycles, 300,000 seat-back tilt cycles, and a 45 kg vertical load target per arm; static seat verification is stated at 680 kg. Procurement teams should note the unbranded presentation and flat-packed supply format. The product is listed as one flat-packed carton, with reference logistics data showing one set per two cartons, a packaged gross weight of 23 kg per set, reference carton dimensions of 850 x 420 x 720 mm, and reference volume of 0.26 m3 per set. Reference assembly time is 40 minutes per set, making receiving, storage, and installation planning important for multi-seat office rollouts.
