Product Description

The High-Back Adjustable Ergonomic Executive Office Chair, model EOCHB-700features a sleek, professional silhouette anchored by a polished chrome-plated steel five-star base, paired with smooth black PU leather upholstery across its tall, contoured high back and generously proportioned seat. The fixed, curved headrest aligns seamlessly with the upper back, while built-in lumbar shaping follows the natural curve of the mid-back for targeted contact, and padded height-adjustable armrests sit at a fixed comfortable height relative to both the seat and floor. The chair’s streamlined, formal lines avoid overly bulky detailing, delivering a polished executive aesthetic that balances support and refined style. Its construction prioritizes long-term commercial durability, starting with a 2.5mm thick welded alloy steel internal backrest frame, paired with a 3mm thick pressed steel butterfly tilt mechanism plate and Class 3 chrome-finished steel gas lift cylinder. The 2mm thick polished steel five-star base supports 50mm diameter dual-wheel nylon casters, while all padded surfaces use 1.2mm thick black PU synthetic leather over high-density CAL 117 flame-retardant polyurethane foam, with 20mm thick soft foam padding on armrest tops. Every core component is engineered for repeated use, with rated performance that supports regular high-frequency utilization. Core functional features include stepless pneumatic seat height adjustment controlled via an under-seat lever, full 360-degree swivel around the central axis, and a backrest that reclines from 90° to 135° with an upright position lock and rotary tilt tension knob to adjust recline resistance to match user weight. The dual-wheel casters roll smoothly across hard floors and low-pile carpet, while the built-in contoured lumbar and head support deliver ergonomic comfort suited for extended seated work, with a recommended weight capacity of 181 kg. This chair fits a wide range of professional settings, including private executive offices supporting 8+ hours of daily seated work, senior staff and manager workstations in open plan layouts, formal boardrooms and client meeting spaces, premium home office interiors, high-traffic commercial co-working spaces, and reception areas where a polished professional appearance supports positive first impressions. For procurement, note that each unit ships in two cartons, requires 40 minutes of assembly per set, has a packaged gross weight of 23 kg per set, and fits 135 units in a 20GP container at 85% space utilization. The product is unbranded, allowing for flexible customization to match organizational branding requirements as needed.
