Product Description

The Tan Upholstered Chrome Executive Office Chair (model JH-1904, unbranded) balances polished professional aesthetics with ergonomic utility for a range of work environments. Its streamlined visual profile pairs warm tan upholstery with reflective polished chrome structural elements, anchored by a wide five-star base that creates a stable, evenly balanced layout. Fixed, upholstery-matching padded armrests sit at a consistent 560mm outer span, framing a 500mm wide seat and 450mm wide, 630mm tall contoured backrest for a tailored, formal silhouette that avoids bulky overdesign. The chair’s overall dimensions measure 560 x 630 x 1070 mm, supported by a 700mm diameter five-star base that keeps the footprint unobtrusive even in tighter work areas. Construction prioritizes durable, long-wearing materials without compromising comfort. Seat and back surfaces are covered in 1.2mm thick tan PU faux leather, with cushioning tailored to support needs: the 500mm deep seat uses 80mm thick, 45kg/m³ high-density polyurethane foam that delivers 95% compression recovery, while the backrest uses 60mm thick, 35kg/m³ high-density polyurethane foam shaped for consistent lumbar contact. Structural components include 2.0mm thick polished chrome-plated steel for the five-star base, 1.5mm thick polished chrome-plated steel for fixed armrest supports, a 50mm diameter Class 3 chrome-plated steel pneumatic gas lift, and a 3mm thick black powder-coated steel tilt mechanism chassis, with an internal 1.2mm plywood panel reinforcing the backrest. 60mm diameter nylon twin-wheel casters with PU treads offer smooth, floor-safe movement across hard surfaces and low-pile carpet. Functional design supports daily work routines, with a maximum 480mm seat height via a 60mm side-lever controlled pneumatic adjustment, full 360-degree swivel rotation, and multi-position back tilt offering a 12-degree maximum recline, a 125-degree total reclined angle with three suggested lock positions, and an under-seat tension knob to adjust tilt resistance to match user weight. The chair supports a maximum user weight of 181 kg, with a tilt mechanism static load rating of 136 kg, 120,000-cycle gas lift durability, and 40,000-cycle caster rolling durability, rated for 8 hours of daily use. It is well suited for executive private offices paired with 2.4m executive desks, mid-century modern conference rooms, compact home workspaces, open plan workstations requiring easy movement between stations, and client reception areas where its finish projects a welcoming, professional tone. Procurement teams should note each unit ships in two cartons with a packaged gross weight of 23 kg and 0.26 m³ total volume, requires 40 minutes of assembly per set, and fits 135 units in a 20GP container at 85% space utilization.
