Product Description

The High-Back Upholstered Executive Swivel Chair, model EXE-HB-520-GRY, presents a formal management-office look through its tall contoured back, wraparound padded armrests, grey smooth upholstery, and polished five-star base. Its coordinated grey seat and back create a streamlined silhouette, while the chrome or polished-metal base, black casters, and black tilt mechanism provide visual contrast. Overall dimensions are 680 by 700 by 1240 mm, with a 540 mm clear width between armrests and a 240 mm lumbar support zone, giving the chair a substantial executive presence suited to refined desk settings. Construction combines upholstered comfort with a structured internal assembly. The outer seat and back use grey smooth upholstery over a contoured shell; the exact leather or polyurethane composition requires confirmation in the supplier bill of materials. The seat cushion uses molded polyurethane foam at 90 mm center thickness, with a 45 kg/m3 procurement density target. Backrest padding is a polyurethane comfort layer, 60 mm thick in the lumbar and shoulder zones, and the integrated headrest pad is 80 mm thick. Curved armrests include soft outer padding over a supportive inner core. The target inner support structure includes a molded seat carrier with a 3 mm steel mechanism-mount plate, a chrome-plated telescoping gas lift, a black painted steel multi-position tilt mechanism, and a polished die-cast aluminum or chrome-finish metal base with a 3 mm wall-thickness target. Daily functions center on adjustable executive seating. The gas lift allows full 360-degree swivel and a 100 mm height-adjustment stroke through a pneumatic lever. The synchronized tilt mechanism permits backrest recline to 15 degrees, with lock positions at upright, 7 degrees, and 15 degrees. A rotary tension knob adjusts recline resistance for users up to 150 kg. Five 60 mm black twin-wheel casters support omnidirectional movement on hard floors and carpet, while fixed wraparound arms place forearm support 220 mm above the seat. The chair is appropriate for private executive offices, manager workstations, premium conference rooms, executive reception areas, and dedicated home offices. For executive use, it can be placed behind a 2000 mm desk; for standard desk work, it suits a 760 mm seated desk height. Home placement should provide at least 800 mm of rear clearance for recline and rotation. It is intended for adult office users up to 150 kg who want upper-back support. Procurement teams should note the unbranded supply model, 21 kg net weight, and verification targets including a 150 kg seat static load, 136 kg backrest static load, 100,000 gas-lift and caster cycles, and 300,000 tilt-mechanism cycles. Each set ships in two cartons with 23 kg packaged gross weight, 0.26 cubic meter total carton volume, and a 40-minute reference assembly time. A 20GP container can accommodate 135 sets at 85 percent space utilization. Buyers should confirm upholstery composition and the target base and plate specifications before finalizing orders.
